Service operations to be performed before customer delivery
are specified in the applicable model year PREDELIVER Y AND
SET-UP MANUAL.
The performance of new motorcycle initial service is required
to keep warranty in f orce and to ensure proper emissions systems operation. See 1.2 MAINTENANCE SCHEDULE.
SAFE OPERATING MAINTENANCE
NOTES
•Do not attempt to retighten engine head bolts. Retightening
can cause engine damage.
•During the initial break-in period, use only Harley-Davidson
20W50 engine oil. F ailure to use the recommended oil will
result in improper break-in of the engine cylinders and
piston rings.
A careful check of certain equipment is necessary after periods
of storage, and frequently between regular service intervals,
to determine if additional maintenance is required.
Check:
1.Tires for abrasions, cuts and correct pressure.
2.Secondary drive belt for proper tension and condition.
3.Brakes, steering and throttle for responsiveness.
4.Brake fluid lev el and condition. Hydraulic lines and fittings
for leaks. Also, check brake pads and rotors for wear.
5.Cables for fraying, crimping and free operation.
General maintenance practices are given in this section.
NOTES
•Repair = Disassembly/Assembly.
•Replacement = Substitute a new part for existing com-
ponent.
All special tools and torque values are noted at the point of
use.
All required parts or materials can be found in the appropriate
PARTS CATALOG.
Safety
Safety is always the most important consideration when performing any job. Be sure you have a complete understanding
of the task to be performed. Use common sense. Use the
proper tools. Protect yourself and bystanders with approved
eye protection. Don't just do the job - do the job safely.
Removing Parts
Always consider the weight of a part when lifting. Use a hoist
whenever necessary. Do not lift heavy parts by hand. A hoist
and adjustable lifting beam or sling are needed to remove some
parts.The lengths of chains or cables from the hoist to the part
should be equal and parallel and should be positioned directly
over the center of the part. Be sure that no obstructions will
interfere with the lifting operation. Nev er leav e a part suspended
in mid-air.
Be sure to check capacity rating and condition of hoists,
slings, chains and cables bef ore use. Exceeding capacity
ratings or using lifting devices that are in poor condition
can lead to an accident, which could result in death or
serious injury. (00466c)
Always use blocking or proper stands to support the part that
has been hoisted. If a part cannot be removed, verify that all
bolts and attaching hardware have been removed. Check to
see if any parts are in the way of the part being removed.
When removing hoses, wiring or tubes, always tag each part
to ensure proper installation.
Cleaning
If you intend to reuse parts, follow good shop practice and
thoroughly clean the parts before assembly. Keep all dirt out
of parts; the unit will perform better and last longer. Seals , filters
and covers are used in this vehicle to keep out environmental
dirt and dust. These items must be kept in good condition to
ensure satisfactory operation.
When you are instructed in a step to clean fastener threads or
threaded holes, proceed as follows: Clean all LOCTITE material
from fastener threads and threaded holes. Use a wire brush
to clean fastener threads. Use a thread chaser or other suitable
tool to clean threaded holes. Use PJ-1 cleaner or equivalent
to remove all traces of oil and contaminants from threads. Blo w
out all threaded holes with low pressure compressed air.
Clean and inspect all parts as they are removed. Be sure all
holes and passages are clean and open. After cleaning, co ver
all parts with clean lint-free cloth, paper or other material. Be
sure the part is clean when it is installed.
Always clean around lines or cov ers bef ore the y are remo v ed.
Plug, tape or cap holes and openings to keep out dirt, dust and
debris.
Always verify cleanliness of blind holes before assembly.
Tightening a screw with dirt, water or oil in the hole can cause
castings to crack or break.
2008 Softail Service: Maintenance 1-1
Page 19
Disassembly and Assembly
Always assemble or disassemble one part at a time. Do not
work on two assemblies simultaneously. Be sure to make all
necessary adjustments. Recheck y our work when finished. Be
sure that everything is done.
Operate the vehicle to perform any final chec k or adjustments.
If all is correct, the vehicle is ready to go back to the customer .
Checking Torques on Fasteners with Lock
Patches
To check the torque on a fastener that has a lock patch:
1.Set the torque wrench for the lowest setting in the specified
torque range.
2.Attempt to tighten fastener to set torque. If fastener does
not move and lowest setting is satisfied (torque wrench
clicks), then the proper torque has been maintained.
Magnetic Parts Trays
Magnetic parts trays are becoming common in the service
facility because they are convenient and can keep parts from
becoming lost during a repair procedure.
Howev er , hardened steel parts can become magnetized when
held in magnetic parts trays. Metal fragments that would
ordinarily be washed away in the oil and tr apped in the oil filter
or magnetic drain plug during vehicle operation could be captured by magnetized parts in the engine, potentially causing
accelerated engine wear and damage.
Parts that will be returned to service inside the vehicle's
powertrain such as gears, thrust washers and especially
bearings should never be kept in magnetic parts trays.
REPAIR AND REPLACEMENT
PROCEDURES
Hardware and Threaded Parts
Install helical thread inserts when inside threads in castings
are stripped, damaged or not capable of withstanding specified
torque.
Replace bolts, nuts, studs, washers, spacers and small
common hardware if missing or in any way damaged. Clean
up or repair minor thread damage with a suitable tap or die.
Replace all damaged or missing lubrication fittings.
Use Teflon pipe sealant or LOCTITE 565 THREAD SEALANT
on pipe fitting threads.
Threadlocking Agents
Always f ollow specific service manual procedures when working
with fasteners containing preapplied threadlocking agents when
fastener replacement is recommended. When re-using
fasteners containing threadlocking agents, be sure to completely remove all existing threadlocking agent from fastener
threads with a wire brush or wire wheel. Also, be sure to
remove residual threadlocking agent from fastener hole using
an appropriate thread chasing device and compressed air when
using new or existing f asteners. Alwa ys use the recommended
threadlocking agent for your specific procedure.
Wiring, Hoses and Lines
Hoses, clamps, electrical wiring, electrical switches or fuel lines
if they do not meet specifications.
Instruments and Gauges
Replace broken or defectiv e instruments and gauges. Replace
dials and glass that are so scratched or discolored that reading
is difficult.
Bearings
Anti-friction bearings must be handled in a special way. To
keep out dirt and abrasives, cover the bearings as soon as
they are removed from the package.
Wash bearings in a non-flammable cleaning solution. Knock
out packed lubricant inside by tapping the bearing against a
wooden block.Wash bearings again. Cover bearings with clean
material after setting them down to dry. Ne ver use compressed
air to dry bearings.
Coat bearings with clean oil.Wrap bearings in clean paper.
When bearings are installed against shoulders, be sure that
the chamfered side of the bearing always faces the shoulder.
Lubricate bearings and all metal contact surfaces before
pressing into place. Only apply pressure on the part of the
bearing that makes direct contact with the mating part. Install
bearings with numbered side facing out.
Always use the proper tools and fixtures for removing and
installing bearings.
Bearings do not usually need to be removed. Only remove
bearings if necessary.
Bushings
Do not remove a bushing unless damaged, excessively worn
or loose in its bore. Press out bushings that m ust be replaced.
When pressing or driving bushings, be sure to apply pressure
in line with the bushing bore. Use a bearing/bushing driver or
a bar with a smooth, flat end. Never use a hammer to drive
bushings.
Inspect the bushing and the mated part for oil holes. Be sure
all oil holes are properly aligned.
Gaskets
Always discard gaskets after removal. Replace with new gas-
kets. Never use the same gasket twice. Be sure that gasket
holes match up with holes in the mating part. But be aware
that sections of a gasket may be used to seal passages.
If a gasket must be made, be sure to cut holes that match up
with the mating part. Serious damage can occur if any flange
holes are blocked by the gasket. Use material that is the right
type and thickness.
Lip Type Seals
Lip seals are used to seal oil or grease and are usually installed
with the sealing lip facing the contained lubricant. Seal orientation, however, may vary under different applications.
Seals should not be removed unless necessary. Only remove
seals if required to gain access to other parts or if seal damage
or wear dictates replacement.
Leaking oil or grease usually means that a seal is damaged.
Replace leaking seals to prevent overheated bearings.
1-2 2008 Softail Service: Maintenance
Page 20
Always discard seals after remov al. Do not use the same seal
twice.
O-Rings (Preformed Packings)
Always discard o-rings after removal. Replace with ne w o-rings.
T o pre vent leaks , lubricate the o-rings before installation. Apply
the same type of lubricant as that being sealed. Be sure that
all gasket, o-ring and seal mating surfaces are thoroughly clean
before installation.
Gears
Always check gears for damaged or worn teeth.
Remove burrs and rough spots with a honing stone or crocus
cloth before installation.
Lubricate mating surfaces before pressing gears on shafts.
Bearings
Remove shields and seals from bearings before cleaning.
Clean bearings with permanent shields and seals in solution.
Using compressed air to "spin dry" bearings can cause
bearing to fly apart, which could result in death or serious
injury. (00505b)
Clean open bearings by soaking them in a petroleum cleaning
solution. Never use a solution that contains chlorine.
Let bearings stand and dry. Do not dry with compressed air.
Do not spin bearings while they are drying.
TOOL SAFETY
Shafts
If a shaft does not come out easily, check that all nuts, bolts
or retaining rings have been removed. Check to see if other
parts are in the way before using force.
Shafts fitted to tapered splines should be very tight. If shafts
are not tight, disassemble and inspect tapered splines. Discard
parts that are worn. Be sure tapered splines are clean, dry and
free of burrs before putting them in place. Press mating parts
together tightly.
Clean all rust from the machined surfaces of new parts.
Part Replacement
Always replace worn or damaged parts with new parts.
Exhaust System Leakage
In the event of an exhaust system leak at a muffler or header
pipe connection location, disassemble and clean all mating
surfaces. Replace any damaged components. If leak still e xists,
disassemble and repair the leak by applying a bead of HarleyDavidson High-Performance Sealant (Part No. 99650-02) (or
an equivalent 02 Sensor/Catalyst-safe alternative). Reassemble
components, wipe off any excess sealant and allo w adequate
curing time following sealant product instructions before operating vehicle.
CLEANING
Part Protection
Before cleaning, protect rubber parts (such as hoses, boots
and electrical insulation) from cleaning solutions. Use a greaseproof barrier material. Remove the rubber part if it cannot be
properly protected.
Cleaning Process
Any cleaning method may be used as long as it does not result
in parts damage. Thorough cleaning is necessary for proper
parts inspection. Strip rusted paint areas to bare metal before
priming and repainting.

FUEL
Refer to Table 1-4. Always use a good quality unleaded gas-
oline. Octane ratings are usually found on the pump.
Avoid spills. Slowly remove filler cap. Do not fill above
bottom of filler neck insert, leaving air space for fuel
expansion. Secure filler cap after refueling. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00028a)
Use care when refueling. Pressurized air in fuel tank can
force gasoline to escape through filler tube. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00029a)
Modern service station pumps dispense a high flow of gasoline
into a motorcycle fuel tank making air entrapment and pressurization a possibility.

be used in your motorcycle.
•ETHANOL is a mixture of 10% ethanol (Grain alcohol) and
90% unleaded gasoline. Gasoline/ethanol blends can be
used in your motorcycle if the ethanol content does not
exceed 10%.
•REFORMULATED OR OXYGENATED GASOLINES
(RFG): Reformulated gasoline is a term used to describe
gasoline blends that are specifically designed to burn
cleaner than other types of gasoline, leaving fe wer tailpipe
emissions. They are also formulated to evaporate less
when you are filling your tank. Reformulated gasolines
use additives to oxygenate the gas. Your motorcycle will
run normally using this type of gas and Harley-Davidson
recommends you use it when possible, as an aid to cleaner
air in our environment.
•Do not use race gas or octane boosters. Use of these fuels
will damage the fuel system.
Some gasoline blends might adversely affect the starting,
driveability or fuel efficiency of the motorcycle. If any of these
problems are experienced, try a different brand of gasoline or
gasoline with a higher octane blend.
ENGINE LUBRICATION
GASOLINE BLENDS
Your motorcycle was designed to get the best performance
and efficiency using unleaded gasoline. Most gasoline is
blended with alcohol and/or ether to create oxygenated blends .
The type and amount of alcohol or ether added to the fuel is
important.
Do not use gasoline that contains methanol. Doing so can
result in fuel system component failure, engine damage
and/or equipment malfunction. (00148a)
•Gasoline containing METHYL TER TIARY BUTYL ETHER
(MTBE): Gasoline/MTBE blends are a mixture of gasoline

H-D RATINGVISCOSITYH-D TYPE
Do not switch lubricant brands indiscriminately because
some lubricants interact chemically when mixed. Use of
inferior lubricants can damage the engine. (00184a)
Engine oil is a major factor in the performance and service life
of the engine. Alwa ys use the proper grade of oil f or the low est
temperature expected before the next scheduled oil change.
Refer to Table 1-5. Your authorized dealer has the proper oil
to suit your requirements.
If it is necessary to add oil and Harley-Davidson oil is not
available, use an oil certified for diesel engines. Acceptable
diesel engine oil designations include: CF-4, CG-4, CH-4 and
CI-4.
The preferred viscosities for the diesel engine oils in descending order are: 20W50, 15W40 and 10W40.
At the first opportunity, see an authorized dealer to change
back to 100 percent Harley-Davidson oil.

miles (24 kilometers), in ambient temperatures below 60°
F (16° C), oil change intervals should be reduced to 1500
miles (2400 kilometers). Motorcycles used only for short runs
must have a thorough tank flush-out before new oil is put in.
The tank flush-out should be performed by an authorized dealer
or qualified technician.
NOTE
The further below freezing the temperature drops, the shorter
the oil change interval should be.
Water vapor is a normal by-product of combustion in any
engine. During cold weather operation, some of the water vapor
condenses to liquid form on the cool metal surfaces inside the
engine. In freezing weather this water will become slush or ice
and, if allowed to accumulate too long, may block the oil lines
and cause damage to the engine.
If the engine is run frequently and allowed to thoroughly warm
up, most of this water will become vapor again and will be
blown out through the crankcase breather.
If the engine is not run frequently and allowed to thoroughly
warm up, this water will accumulate, mix with the engine oil
and form a sludge that is harmful to the engine.

CHECKING AND ADDING OIL
sm03037
sm03039
See Figure 1-1. Checking engine oil level:
•As part of the pre-ride inspection.
•At every scheduled service interval.
Type of Oil
Refer to Table 1-5. Use the proper grade of oil for the lowest
temperature expected before the ne xt oil change. See 1.3 FUEL
AND OIL for specific information regarding winter needs.
If it is necessary to add oil and Harley-Davidson oil is not
available, use an oil certified for diesel engines. Acceptable
diesel engine oil designations include CF-4, CG-4, CH-4, and
CI-4. The preferred viscosities for the diesel engine oils, in
descending order, are 20W-50, 15W-40 and 10W-40. At the
first opportunity, see a Harley-Da vidson dealer to change back
to 100 percent Harley-Davidson oil.
1.5ENGINE OIL AND FILTER
Figure 1-2. Oil Tank Dipstick Upper Groove
Checking Oil Level
Oil level cannot be accurately measured on a cold engine.
For pre-ride inspection, with motorcycle leaning on jiffy
stand on level ground, oil should register on dipstick
between arrows when engine is cold. Do not add oil to
bring the level to the FULL mark on a COLD engine.
(00185a)
Ride motorcycle until engine is warmed up to operating temperature, then do the following.
1.Idle motorcycle on jiffy stand for 1-2 minutes.
2.Shut motorcycle off and leave motorcycle resting on jiffystand.
3.See Figure 1-2. Check oil level on dipstick. If necessary,
add oil until oil registers at upper groove on dipstick. Do
not overfill oil tank.
•If the motorcycle is ridden hard, under dusty conditions,
or in cold weather, the oil and filter should be changed
more often.
•All Softail models are shipped from the factory with SAE
20W50 Harley-Davidson 360 Motor Oil.
•All Softail models come equipped from the factory with a
premium 5 micron synthetic media oil filter, Part No.
63798-99 (Chrome) or 63731-99 (Black). These are the
only recommended replacement filters.
1.Ride motorcycle until engine is warmed up to normal
operating temperature.
2.See Figure 1-1. Remove the engine oil filler plug/dipstick
by pulling steadily while moving plug back and forth.
3.See Figure 1-3. Remove the engine oil drain plug with oring (2). Allow oil to drain into a suitable container.

use your hand to check for air leaks or to determine air
flow rates. (00061a)
6.Clean filter element.
a.Wash the paper/wire mesh air filter element and
breather hoses in lukewarm water with a mild detergent. Do not strike filter element on a hard surface to
dislodge dirt.
b.Allow filter to either air dry or blow it dry, from the
inside, with low pressure air. Do not use air cleaner
filter oil on the Harley-Davidson paper/wire mesh air
filter element.
c.Hold the filter element up to a strong light source. If
light is uniformly visible through the element, it is
sufficiently clean.
7.Inspect seal ring (3) on cover for cracks or tears. Verify
that it seals tightly to backplate. Replace as required.
8.Inspect breather hoses for tears, cuts, holes or other
damage. Replace as necessary.
NOTE
The breather hoses allow crankcase vapors to be directed into
the air filter element. By providing effective recirculation of
crankcase vapor, the hoses serve to eliminate the pollutants
normally discharged from the crankcase. Air cleaner mounting
without installation of the breather hoses, or with breather hoses
that are not air tight, allows crankcase vapors to be v ented into
the atmosphere in violation of legal emissions standards.This
will also negatively affect the engine's breather system as it
will cause the umbrella valve to flutter.
9.Wipe inside of air cleaner cover and backplate with damp
cloth to remove dust.

1.8TIRES AND WHEELS
TIRES
Match tires, tubes, air valves and caps to the correct wheel
rim. Contact a Harley-Davidson dealer. Mismatching can
result in damage to the tire bead, allow tire slippage on
the rim or cause tire failure, which could result in death
or serious injury. (00023a)
Use only Harley-Davidson approved tires. See a HarleyDavidson dealer . Using non-approved tires can adversely
affect stability, which could result in death or serious
injury. (00024a)
Use inner tubes on laced (wire spoked) wheels. Using
tubeless tires on laced wheels can cause air leaks, which
could result in death or serious injury. (00025a)
Table 1-7.Tire Pressures: 2008 Softail Models
NOTES
•Tubeless tires are used on all Harley-Davidson cast and
disc wheels.
•Tire sizes are molded on the tire sidewall. Inner tube sizes
are printed on the tube.
•New tires should be stored on a horizontal tire rack. Avoid
stacking new tires in a vertical stack. The weight of the
stack compresses the tires and closes down the beads.
Check tire pressure and tread:
•As part of the pre-ride inspection.
•At every scheduled service interval.
1.Inspect each tire for punctures, cuts and breaks.
2.Inspect each tire for wear . Replace tires bef ore they reach
the tread wear indicator bars.
NOTE
Missing indicator wear bars represent less than 1/32 in. (0.8
mm) tread pattern depth remaining.
3.Check for proper front and rear tire pressures when tires
are cold. Compare results against Table 1-7.
TIRE REPLACEMENT
Inspection
Harley-Davidson tires are equipped with wear bars that
run horizontally across the tread.When wear bars become
visible and only 1/32 in. (0.8 mm) tread depth remains,
replace tire immediately. Using a worn tire can adversely
affect stability and handling, which could result in death
or serious injury. Use only Harley-Davidson approved
replacement tires. (00090b)
See Figure 1-12. Arrows on tire sidewalls pinpoint location of
wear bar indicators.

Figure 1-13. Always replace tires before the tread wear indic-
ator bars appear.
When To Replace Tires
New tires are needed if any of the following conditions exist:
1.Tread wear indicator bars become visible on the tread
surfaces.
2.Tire cords or fabric become visible through cracked sidewalls, snags or deep cuts.
3.A bump, bulge or split in the tire.
4.Puncture, cut or other damage to the tire that cannot be
repaired.

2.Inspect any time the wheels are removed.
a.Inspect the play of the wheel bearings by finger while
they are in the wheel.
b.Rotate the inner bearing race and check for abnormal
noise.
c.Make sure bearing rotates smoothly.
3.Check wheel bearings and axle spacers for wear and
corrosion. Excessive play or roughness indicates worn
bearings. Replace bearings in sets only. See 2.6 SEALED
WHEEL BEARINGS, Inspection.
WHEEL SPOKES
Spokes that are too tight can draw nipples through the rim
or distort hub flanges. Spokes that are too loose can
continue to loosen when put in service. Either condition
can adversely affect stability and handling, which could
result in death or serious injury. (00286a)
If nipples require more than one full turn to tighten spoke,
remove tire to check that spoke protrusion has not damaged tube. (00526b)

When a drive belt is replaced for any reason other than stone
damage, it is recommended that the transmission and rear
sprockets also be replaced to increase the longevity of the ne w
drive belt. In the case of stone damage, inspect sprockets for
damage and replace as required.
Never bend belt forward into a loop smaller than the drive
sprocket diameter. Never bend belt into a reverse loop.
Over bending can damage belt resulting in premature
failure, which could cause loss of control and death or
serious injury. (00339a)

•Cuts or unusual wear patterns.
•Outside edge bevelling (8). Some bevelling is common,
but it indicates that sprockets are misaligned.
•Outside ribbed surface for signs of stone puncture (7). If
cracks/damage exists near edge of belt, replace belt
immediately. Damage to center of belt will require belt
replacement eventually, but when cracks extend to edge
of belt, belt failure is imminent.
•Inside (toothed portion) of belt for exposed tensile cords
(normally covered by nylon la yer and polyethylene layer).
This condition will result in belt failure and indicates worn
transmission sprocket teeth. Replace belt and transmission
sprocket.
•Signs of puncture or cracking at the base of the belt teeth.
Replace belt if either condition exists.
•Replace belt if conditions 2, 3, 6 or 7 (on edge of belt)
exist.
NOTE
Condition 1 may develop into 2 or 3 over time. Condition 1 is
not grounds for replacing the belt, but it should be watched
closely before condition 2 develops which will require belt
replacement.

TOOL NAMEPART NUMBER
BELT TENSION GAUGEHD-35381-A
NOTE
Do not rely on "feel" for the proper deflection as this typically
results in belts which are under tensioned. Always use BELT
TENSION GAUGE (Part No. HD-35381-A) to determine the
10 lbs (4.5 kg) deflection force. Loose belts will fail due to
"ratcheting" (jumping a tooth) with resultant tensile cord
crimping and breakage.
Check rear belt deflection:
•As part of the pre-ride inspection.
•At every scheduled service interval.
When checking belt deflection:
•Set belt tension at tightest point in belt.
•Perform procedure with motorcycle cold.
NOTE
Customers may purchase belt tension gauge from an authorized Harley-Davidson dealer.
1.See Figure 1-26. Obtain BELT TENSION GAUGE (Part
No. HD-35381-A).
2.To use the belt tension gauge:
a.Slide o-ring (4) toward 0 lbs (0 kg) mark (3).
b.Fit belt cradle (2) against bottom of drive belt half-way
between drive pulleys (point 1 in Figure 1-27.)
c.Press upward on knob (6) until o-ring slides down to

Adjustment
The throttle control must operate freely without binding. With
the throttle friction adjustment screw backed off, the throttle
grip must freely return to the closed (idle) position.The throttle
control also must open and close freely when the front wheel
is turned to both the right and left fork stops. If the throttle grip
does not return to the idle position freely, check the throttle
friction adjustment screw tension. If the adjuster screw is
backed off, inspect the cables for short bends.

adjuster mechanism with rubber boot.
6.Turn the front wheel full right.Turn the idle cable adjuster
counterclockwise until the cable housing (4) just touches
the spring (6) in the cable guide (as seen through slot).
7.Work the throttle grip to verify that the throttle cable returns
to the idle position when released. If the cable does not
return to idle, turn the cable adjuster clockwise slightly
until the correct response is achieved.
8.Tighten jam nut against the cable adjuster and cover cab le
adjuster mechanism with rubber boot.

Safety Precautions
Never charge a battery without first reviewing the instructions
for the charger being used. In addition to the manufacturer's
instructions, follow these general safety precautions:
•Always wear eye, face and hand protection.
•Always charge batteries in a well-ventilated area.
•Turn the charger off before connecting the leads to the
battery to avoid dangerous sparks.
•Never try to charge a visibly damaged or frozen battery.
•Connect the charger leads to the battery; red positive (+)
lead to the positive (+) terminal and black negative (-) lead
to the negative (-) terminal. If the battery is still in the
vehicle, connect the negative lead to the chassis g round.
Be sure that the ignition and all electrical accessories are
turned off.
•Make sure that the charger leads to the battery are not
broken, frayed or loose.
•If the battery gets hotter than 110° F (43° C) during
charging, discontinue charger and allow the battery to
cool.
•Always turn the charger off before removing charger leads
from the battery to avoid dangerous sparks.
Using a Battery Charger
Charge the battery if any of the following conditions exist:
•Vehicle lights appear dim.
•Electric starter sounds weak.
•Battery has not been used for an extended period of time.
Voltmeter Test
Refer to Table 1-13. The voltmeter test provides a general
indicator of battery condition. Check the v oltage of the battery
to verify that it is in a 100% fully charged condition. If the open
circuit (disconnected) voltage reading is below 12.6V, charge
the battery and then recheck the voltage after the battery has
set for one to two hours. If the voltage reading is 12.7V or
above, perform a load test. See the ELECTRICAL DIAGNOSTIC MANUAL for the load test procedure.
1-38 2008 Softail Service: Maintenance
Explosive hydrogen gas, whic h escapes during char ging,
could cause death or serious injury. Charge battery in a
well-ventilated area. Keep open flames, electrical sparks
and smoking materials away from battery at all times.
KEEP BATTERIES AWAY FROM CHILDREN. (00065a)
If battery releases an excessive amount of gas during
charging, decrease the charging rate. Overheating can
result in plate distortion, internal shorting, drying out or
damage. (00413b)
Page 56
1.Perf orm a voltmeter test to determine the state of charge.
See the ELECTRICAL DIAGNOSTIC MANUAL. If battery
needs to be charged, proceed to the next step.
The figures listed in the table assume that the battery is charging at room temperature. If warmer than room temperature,
use a slightly shorter charging time. If colder, use a slightly
longer charging time.
The use of constant current chargers to charge sealed maintenance-free batteries is not recommended. Any overcharge
will cause dry-out and premature battery failure. If a constant
current charger is the only type available, do not exceed the
charge times listed above and do not continue charging the
battery if it gets hot.When charging, never exceed 15 v olts f or
more than 30 minutes.
Unplug or turn OFF battery charger before connecting
charger cables to battery . Connecting cables with charger
ON can cause a spark and battery explosion, which could
result in death or serious injury. (00066a)
Do not reverse the charger connections described in the
following steps or the charging system of the motorcycle
could be damaged. (00214a)
2.Connect red battery charger lead to the positive (+) terminal of the battery.
3.Connect black battery charger lead to the negative (-)
terminal of the battery.
NOTE
If the battery is still in the vehicle, connect the negative lead
to the chassis ground. Be sure that the ignition and all electrical
accessories are turned off.
4.Step away from the battery and turn on the charger. See
the charging instructions in Table 1-14.
Unplug or turn OFF battery charger before disconnecting
charger cables from battery. Disconnecting clamps with
charger ON can cause a spark and battery explosion, which
could result in death or serious injury. (00067a)
5.After the battery is fully charged, disconnect the black
battery charger lead to the negative (-) terminal of the
battery.
6.Disconnect the red battery charger lead to the positive (+)
terminal of the battery.
7.Mark the charging date on the battery.
8.Perf orm either a conductance test or load test to determine
the condition of the battery. See the ELECTRICAL DIAGNOSTIC MANUAL.
9.If charging battery because voltmeter test reading was
below 12.6 V, perform voltmeter test. See the ELECTRICAL DIAGNOSTIC MANUAL.
DISCONNECTION AND REMOVAL
Disconnect negative (-) battery cable first. If positive (+)
cable should contact ground with negative (-) cable connected, the resulting sparks can cause a battery explosion,
which could result in death or serious injury. (00049a)

Batteries contain sulfuric acid, which could cause severe
burns to eyes and skin. Wear a protective face shield,
rubberized gloves and protective clothing when working
with batteries. KEEP BA TTERIES A W A Y FROM CHILDREN.
(00063a)
Do not allow battery to completely discharge.The electrolyte in a discharged battery will freeze. The more discharged a battery is, the more easily it can freeze and crack
the battery case. (00218a)
If the motorcycle is to be stored with the security system armed,
connect a GLOBAL BATTERY CHARGER (Part No. 9986301A) to maintain battery charge.
If the motorcycle is to be stored with the battery installed, a
GLOBAL BATTERY CHARGER unavailable, and with the
security system not armed, unplug the maxi-fuse.
If the motorcycle will not be operated for sev eral months , such
as during the winter season, remove the battery from the
motorcycle and fully charge.
See Figure 1-46. Self-discharge is a normal condition and
occurs continuously at a rate that depends on the ambient
temperature and the battery's state of charge. Batteries discharge at a faster rate at higher ambient temperatures. To
reduce the self-discharge rate, store battery in a cool (not
freezing), dry place.
Charge the battery every month if stored at temperatures below
60° F (16° C). Charge the battery more frequently if stored in
a warm area above 60° F (16° C).

INSPECTION
Disconnecting spark plug cable with engine running can
result in electric shock and death or serious injury.
(00464b)
1.After the engine has cooled to room temperature, disconnect cables from both spark plugs.
2.Remove spark plugs. If a plug has eroded electrodes,
heavy deposits or a cracked insulator, discard it.
3.See Figure 1-52. Compare your observations of the plug
deposits with the descriptions provided below.
a.A wet, black and shiny deposit on plug base, elec-
trodes and ceramic insulator tip indicates an oil fouled
plug. The condition may be caused by one or more
of the following: worn pistons, worn piston rings, worn
valves, worn valve guides, worn valve seals, a weak
battery or a faulty ignition system.
b.A dry, fluffy or sooty black deposit indicates an air-
fuel mixture that is too rich.
c.A light brown, glassy deposit indicates an overheated
plug. This condition may be accompanied by cracks
in the insulator or by erosion of the electrodes and is
caused by an air-fuel mixture that is too lean, a hotrunning engine, valves not seating or improper ignition
timing. The glassy deposit on the spark plug is a
conductor when hot and may cause high-speed misfiring. A plug with eroded electrodes, heavy deposits
or a cracked insulator must be replaced.
d.A plug with a white, yellow, tan or rusty brown
powdery deposit indicates balanced combustion.
Clean off spark plug deposits at regular intervals.
6.Check condition of threads on cylinder head and plug. If
necessary to remove deposits, apply penetrating oil and
clean out with a thread chaser.
7.Apply LOCTITE ANTI-SEIZE to the spark plug threads.
Install and tighten to 12-18 ft-lbs (16.3-24.4 Nm).
8.Connect spark plug cables. Rear cylinder plug cable
attaches to top coil terminal.Verify that cables are securely
connected to coil and spark plugs.
Figure 1-52.Typical Spark Plug Deposits
SPARK PLUG CABLE INSPECTION
Compressed air can pierce the skin and flying debris from
compressed air could cause serious eye injury. Wear
safety glasses when working with compressed air. Never
use your hand to check for air leaks or to determine air
flow rates. (00061a)
4.If the plugs require cleaning between tune-ups, proceed
as follows:
a.Degrease firing end of spark plug using ELECTRICAL
CONT A CT CLEANER. Dry plug with compressed air.
b.Use a thin file to flatten spark plug electrodes. A spark
plug with sharp edges on its electrodes requires 2540% less firing voltage than one with rounded edges.
c.If the plugs cannot be cleaned, replace with new
spark plugs.
5.Check electrode gap with a wire-type feeler gauge. Bend
the outside of the electrode so only a slight drag on the
gauge is felt when passing it between electrodes. Proper
gap measurement is 0.038-0.043 in. (0.97-1.09 mm).
1-44 2008 Softail Service: Maintenance
1.Inspect spark plug cables. Replace cables that are worn
or damaged.
a.Check for cracks or loose terminals.
b.Check for loose fit on ignition coil and spark plugs.
2.Check cable boots/caps for cracks or tears. Replace
boots/caps that are worn or damaged.
3.See Figure 1-53. Check spark plug cable resistance with
an ohmmeter. Compare values from test with Table 1-15.
Replace cables not meeting resistance specifications.
1.Support motorcycle in an upright position so the front end

8.Check light beam for alignment.
a.The main beam, which is a broad, flat pattern of light,
should be centered equally above and below the
horizontal line.
b.The main beam of light should also be directed
straight ahead. Properly adjusted headlamps project
an equal area of light to right and left of center.
If the motorcycle will not be operated for sev eral months , such
as during the winter season, there are several things which
should be done to protect parts against corrosion, to preserve
the battery and to prevent the buildup of gum and varnish in
the fuel system.
This work should be performed by your local Harley-Davidson
dealer or other qualified technician following Service Manual
procedures.
PLACING IN STORAGE
TOOL NAMEPART NUMBER
STORAGE COVER98716-87A
Do not store motorcycle with gasoline in tank within the
home or garage where open flames, pilot lights, sparks or
electric motors are present. Gasoline is extremely flammable and highly explosive, which could result in death
or serious injury. (00003a)
1.Run motorcycle until engine is at normal operating temperature. Stop the engine then drain the oil tank, install a new
oil filter, and fill oil tank with the proper grade oil. Check
the transmission lubricant level.
Avoid spills. Slowly remove filler cap. Do not fill above
bottom of filler neck insert, leaving air space for fuel
expansion. Secure filler cap after refueling. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00028a)
8.Inspect operation of all electrical equipment and switches.
9.Check tire inflation and inspect tires for wear and/or
damage. See 1.8 TIRES AND WHEELS. If the motorcycle
will be stored for an extended period of time, securely
support the motorcycle under the frame so that all weight
is off the tires.
Be sure that brake fluid or other lubricants do not contact
brake pads or discs. Such contact can adversely affect
braking ability , which could cause loss of contr ol, resulting
in death or serious injury. (00290a)
10. Wash painted and chrome-plated surfaces. Apply a light
film of oil to exposed unpainted surfaces.
Unplug or turn OFF battery charger before connecting
charger cables to battery . Connecting cables with charger
ON can cause a spark and battery explosion, which could
result in death or serious injury. (00066a)
Explosive hydrogen gas, whic h escapes during char ging,
could cause death or serious injury. Charge battery in a
well-ventilated area. Keep open flames, electrical sparks
and smoking materials away from battery at all times.
KEEP BATTERIES AWAY FROM CHILDREN. (00065a)
11. Remove battery from vehicle. Charge battery until the
correct voltage is obtained. Charge the battery every other
month if it is stored at temperatures below 60° F (16° C).
Charge battery once a month if it is stored at temperatures
above 60° F (16° C). See 1.17 BATTERY MAINTEN-
ANCE.
Use care when refueling. Pressurized air in fuel tank can
force gasoline to escape through filler tube. Gasoline is
extremely flammable and highly explosive, which could
result in death or serious injury. (00029a)
2.Prepare your fuel system by filling fuel tank and adding a
gasoline stabilizer. Use one of the commercially availab le
gasoline stabilizers following the manufacturer's instructions.
3.Remove the spark plugs, inject a fe w squirts of engine oil
into each cylinder and crank the engine 5-6 revolutions.
Reinstall spark plugs.
4.Inspect rear belt deflection. See 1.13 REAR BELT
DEFLECTION.
5.Inspect rear belt and sprockets. See 1.12 REAR BELT
AND SPROCKETS.
6.Inspect air cleaner filter. See 1.7 AIR CLEANER AND
EXHAUST SYSTEM.
7.Lubricate controls. See 1.24 CABLE AND CHASSIS
LUBRICATION.
Unplug or turn OFF battery charger before disconnecting
charger cables from battery. Disconnecting clamps with
charger ON can cause a spark and battery explosion, which
could result in death or serious injury. (00067a)
12. If the motorcycle is to be covered, use a material that will
breathe, such as STORAGE COVER (Part No. 9871687A) or light canvas. Plastic materials that do not breathe
promote the formation of condensation, which leads to
corrosion.
REMOVAL FROM STORAGE
The clutch failing to disengage can cause loss of control,
which could result in death or serious injury. Prior to
starting after extended periods of storage, place transmission in gear and push vehicle back and forth several times
to assure proper clutch disengagement. (00075a)
1.Charge and install the battery.
