Read OWNER’S MANUAL before operating.

Foreword

This manual is designed primarily for use by
trained mechanics in a properly equipped shop.
However, it contains enough detail and basic in­formation to make it useful to t he owner who de­sires to perform his own basic maintenance and
repair work. A basic knowledge of mechanics,
the proper use of tools, and workshop proce­dures must be understood in order to carry out
maintenance and repair satisfactorily. When­ever the owner has insufficient experience or
doubts his ability to do the work, all adjust­ments, maintenance, and repair should be car­ried out only by qualified mechanics.

In order to perform the work efficiently and
to avoid costly mistakes, read the text, thor­oughly familiarize yourself with the procedures
before starting work, and then do the work care­fully in a clean area. Whenever special tools or
equipment are specified, do not use makeshift
tools or equipment. Precision measurements
can only be made if the proper instruments are
used, and the use of substitute tools may ad­versely affect safe operation.

For the duration of the warranty period,

we recommend that all repairs and scheduled
maintenance be performed in accordance with
this service manual. Any owner maintenance or
repair procedure not performed in accordance
with this manual may void the warranty.

To get the longest life out of your vehicle:

Follow the Periodic Maintenance Chart in the

•

Service Manual.

Be alert for problems and non-scheduled

•

maintenance.

Use proper tools and genuine Kawasaki Mo-

•

torcycle parts. Special tools, gauges, and

testers that are necessary when servicing

Kawasaki motorcycles are introduced by the

Special Tool Catalog or Manual. Genuine

parts provided as spare parts are listed in the

Parts Catalog.

Follow the procedures in this manual care-

•

fully. Don’t take shortcuts.

Remember to keep complete records of main-

•

tenance and repair with dates and any new

parts installed.

How to Use This Manual

comprehensive Table of Contents.

For example, if you want ignition coil informa­tion, use the Quick Reference Guide to locate
the Electrical System chapter. Then, use the
Table of Contents on the first page of the chap­ter to find the ignition coil section.

Whenever you see these WARNING and
CAUTION symbols, heed their instructions!
Always follow safe operating and maintenance
practices.

This warning symbol identifies special

instructions or procedures which, if not

correctly followed, could result in per-

sonal injury, or loss of life.

CAUTION

This caution symbol identifies special

instructions or procedures which, if not

strictly observed, could result in dam-

age to or destruction of equipment.

This manual contains four more symbols (in
addition to WARNING and CAUTION) which will
help you distinguish different types of informa­tion.

NOTE

This note symbol indicates points of par-

○

ticular interest for more efficient and con-

venient operation.

Indicates a procedural step or work to be

•

done.

take based on the results of the test or inspec-

tion in the procedural step or sub-step it fol-

lows.
In most chapters an exploded view illustration
of the system components follows the Table of
Contents. In these illustrations you will find the
instructions indicating which parts require spec­ified tightening torque, oil, grease or a locking
agent during assembly.

1-2 GENERAL INFORMATION

Before Servicing

Before starting to perform an inspection service or carry out a disassembly and reassembly opera­tion on a motorcycle, read the precautions given below. To facilitate actual operations, notes, illustra­tions, photographs, cautions, and detailed descriptions have been included in each chapter wherever
necessary. This section explains the items that require particular attention during the removal and
reinstallation or disassembly and reassembly of general parts.

Especially note the following:

Battery Ground

Before completing any service on the motorcycle, discon­nect the battery wires from the battery to prevent the engine
from accidentally turning over. Disconnect the negative wire
(–) first and then the positive (+). When completed with the
service, first connect the positive (+) wire to the positive (+)
terminal of the battery then the negative (–) wire to the neg­ative terminal.

Edges of Parts

Lift large or heavy parts wearing gloves to prevent injury
from possible sharp edges on the parts.

Solvent

Use a high flush point solvent when cleaning parts. High
flush point solvent should be used according to directions
of the solvent manufacturer.

Cleaning vehicle before disassembly

Clean the vehicle thoroughly before disassembly. Dirt or
other foreign materials entering into s ealed areas during ve­hicle disassembly can cause excessive wear and decrease
performance of the vehicle.

Before Servicing

Arrangement and Cleaning of Removed Parts

Disassembled parts are easy to confuse. Arrange the
parts according to the order the parts were disassembled
and clean the parts in order prior to assembly.

Storage of Removed Parts

After all the parts including subassembly parts have been
cleaned, store the parts in a clean area. Put a clean cloth
or plastic sheet over the parts to protect from any foreign
materials that may collect before re-assembly.

GENERAL INFORMATION 1-3

Inspection

Reuse of worn or damaged parts may lead to serious ac­cident. Visually inspect removed parts for corrosion, discol­oration, or other damage. Refer to the appropriate sections
of this manual for service limits on individual parts. Replace
the parts if any damage has been found or if the part is be­yond its service limit.

Replacement Parts

Replacement Parts must be KAWASAKI genuine or
recommended by KAWASAKI. Gaskets, O-rings, Oil seals,
Grease seals, circlips or cotter pins must be replaced with
new ones whenever disassembled.

Assembly Order

In most cases assembly order is the reverse of disassem­bly, however, if assembly order is provided in this Service
Manual, follow the procedures given.

1-4 GENERAL INFORMATION

Before Servicing

Tightening Sequence

Generally, when installing a part with several bolts, nuts,
or screws, start them all in their holes and tighten them to
a snug fit. Then tighten them according to the specified se­quence to prevent case warpage or deformation which can
lead to malfunction. Conversely when loosening the bolts,
nuts, or screws, first loosen all of them by about a quar­ter turn and them remove them. If the specified tightening
sequence is not indicated, tighten the fasteners alternating
diagonally.

Tightening Torque

Incorrect torque applied to a bolt, nut, or screw may
lead to serious damage. Tighten fasteners to the specified
torque using a good quality torque wrench.

Force

Use common sense during disassembly and assembly,
excessive force can cause expensive or hard to repair dam­age. When necessary, remove screws that have a non

-permanent locking agent applied using an impact driver.
Use a plastic-faced mallet whenever tapping is necessary.

Gasket, O-ring

Hardening, shrinkage, or damage of both gaskets
and O-rings after disassembly can reduce sealing per­formance. Remove old gaskets and clean the sealing
surfaces thoroughly so that no gasket material or other
material remains. Install new gaskets and replace used
O-rings when re-assembling.

Liquid Gasket, Locking Agent

For applications that require Liquid Gasket or a Locking
agent, clean the surfaces so that no oil residue remains be­fore applying liquid gasket or locking agent. Do not apply
them excessively. Excessive application can clog oil pas­sages and cause serious damage.

Before Servicing

Press

For items such as bearings or oil seals that must be
pressed into place, apply small amount of oil to the con­tact area. Be sure to maintain proper alignment and use
smooth movements when installing.

Ball Bearing and Needle Bearing

Do not remove pressed ball or needle unless removal is
absolutely necessary. Replace with new ones whenever
removed. Press bearings with the manufacturer and size
marks facing out. Press the bearing into place by putting
pressure on the correct bearing race as shown.

Pressing the incorrect race can cause pressure between
the inner and outer race and result in bearing damage.

GENERAL INFORMATION 1-5

Oil Seal, Grease Seal

Do not remove pressed oil or grease seals unless removal
is necessary. Replace with new ones whenever removed.
Press new oil seals with manufacture and size marks facing
out. Make sure the seal is aligned properly when installing.

Apply specified grease to lip of seal before installing the
seal.

Circlips, Cotter Pins

Replace circlips or cotter pins that were removed with new
ones. Take care not to open the clip excessively when in­stalling to prevent deformation.

1-6 GENERAL INFORMATION

Before Servicing

Lubrication

It is important to lubricate rotating or sliding parts during
assembly to minimize wear during initial operation. Lubri­cation points are called out throughout this manual, apply
the specific oil or grease as specified.

Direction of Eng ine Rotation

When rotating the crankshaft by hand, the free play
amount of rotating direction will affect the adjustment. Ro­tate the crankshaft to positive direction (clockwise viewed
from output side).

Electrical Wires

A two-color wire is identified first by the primary color and
then the stripe color. Unless instructed otherwise, electrical
wires must be connected to those of the same color.

Torque and Locking Agent

Tighten all bolts and nuts to the proper torque using an accurate torque wrench. An insufficiently
tightened bolt or nut may become damaged or fall off, possibly resulting in damage to the motorcycle
and injury to the rider. A bolt or nut which is overtightened may become damaged, strip an internal
thread, or break and then fall out. The following table lists the tightening torque for the major bolts
and nuts, and the parts requiring use of a non-permanent locking agent or liquid gasket.

When checking the tightening torque of the bolts and nuts, first loosen the bolt or nut by half a turn
and then tighten it to the specified torque.
Letters used in the "Remarks" column mean:

EO: Apply engine oil to the threads and seating surface.

L: Apply a non-permanent locking agent to the threads.

LG: Apply l iquid gasket to the threads.

Lh: Left-hand threads.

M: Apply molybdenum disulfide grease.

MO: Apply molybdenum disulfide oil (mixture of the engine oil and molybdenum disulfide grease in

a weight ratio 10 : 1)
R: Replacement parts.
S: Tighten the fasteners following the specified sequence.

SS: Apply silicone sealant to the threads.

St: Stake the fasteners to prevent loosening.

Maintenance Procedure

Fuel System

Throttle Cable Inspection

Throttle Grip Free Play Inspection

Check throttle grip play [A] by lightly turning the throttle

•

grip back and forth.
If the free play is improper, adjust the throttle cable.

Throttle Grip Free Play

Standard: 2 ∼ 3 mm (0.08 ∼ 0.12 in.)

Check that the throttle grip moves smoothly from full open

•

to close, and the throttle closes quickly and completely in
all steering positions by the return spring.
If the throttle grip does not return properly, check the throt­tle cable routing, grip free play, and cable damage. Then
lubricate the throttle cable.
Run the engine at the idle speed, and turn the handlebar

•

all the way to the right and left to ensure that the idle speed
does not change.
If the idle speed increase, check the throttle cable free
play and the cable routing.

Throttle Grip Free Play Adjustment

If the free play is incorrect, loosen the locknut [A] and turn

the adjuster [B] of the accelerator cable until the 2 ∼3mm
(0.08 ∼ 0.12 in.) of throttle grip play is obtained.

Tighten the locknut against the adjuster securely.

•

Check that the throttle pulley [A] stops against the idle

•

adjusting screw [B] with the throttle grip closed.

Maintenance Procedure

If the play can not be adjusted by using the adjuster at the
throttle grip, use the adjuster [A] of the decelerator cable
under the fuel tank.
Screw in the adjuster fully at the throttle grip and tighten

•

the locknut.
Remove the fuel tank (see Fuel Tank Removal in the Fuel

•

System chapter).
Make the necessary free play adjustment at the lower ca-

○

ble end.

Check that the throttle pulley stops [A] against the idle

•

adjusting screw [B], with the throttle grip released and
stops against the carburetor stopper with the throttle grip
opened.
Turn the handlebar from side to side while idling the en-

•

gine.
If idle speed varies, the cable may be poorly routed or
damaged.

PERIODIC MAINTENANCE 2-15

WARNING

Operation with an improperly adjusted, incorrectly
routed, or damaged cable could result in an unsafe
riding condition.

Throttle Cable Inspection

Remove both ends of the throttle cables.

•

With the throttle cable disconnected at both ends, the ca-

•

ble should move freely [A] within the cable housing.
If cable movement is not free after lubricating, if the cable

○

is frayed [B], or if the cable housing is kinked [C], replace
the cable.

Idle Speed Inspection

Idle Speed Inspection

Start the engine and warm it up thoroughly.

•

With the engine idling, turn the handlebar to both sides.

•

If handlebar movement changes the idle speed, the throt­tle cable may be improperly adjusted or incorrectly routed,
or it may be damaged. Be sure to correct any of these
conditions before riding.

WARNING

Operation with improperly adjusted, incorrectly
routed, or damaged cables could result in an un­safe riding condition.

Check idle speed.

•

If the idle speed is out of the specified range, adjust it.

Idle Speed

1 200 ±50 r/min (rpm)

2-16 PERIODIC MAINTENANCE

Maintenance Procedure

Idle Speed Adjustment

Start the engine and warm it up thoroughly.

•

Turn the adjusting screw [A] until idle speed is correct.

•

Open and close the throttle a few times to make sure that

○

the idle speed is within the specified range. Readjust if
necessary.

Carburetor Synchronization Inspection

Synchronization Inspection

Situate the motorcycle so that it is perpendicular to the

•

ground.
Remove the fuel tank and connect the auxiliary fuel tank

•

to supply the fuel.
Warm up the engine.

•

Check idle speed and adjust if necessary.

•

Pull the vacuum hoses off, and attach vacuum gauge [A]

•

to the vacuum hose fittings on the carburetors.

Special Tool - Vacuum Gauge: 57001-1369

Synchronization Adjustment

The pilot screw is set at the factory and should not be

○

removed. But if necessary, check the pilot screw opening
as follows.
Turn in the pilot screw and count the number of turns until

•

it seats fully but not tightly, and then remove the screw.
This is to set the screw to its original (correct) position
when assembling.

Special Tool - Pilot Screw Adjuster, C [A]: 57001-1239

NOTE

Each carburetor has different opening of the pilot screw.

○

When setting the pilot screw, do not refer to the specifi­cations which show mean opening of the pilot screws.

Maintenance Procedure

Coolant Filter Cleaning

Before winter season starts, clean the coolant filter [A] in

○

the carburetor system.
Drain the coolant (see Coolant Draining).

•

Remove the coolant filter from the cooling hoses in the

•

carburetor system.
Blow dirt and sediment off the filter with compressed air.

•

Fuel Hoses and Connections Check

The fuel hoses are designed to be used throughout the

○

motorcycle’s life without any maintenance, however, if the
motorcycle is not properly handled, the high pressure in­side the fuel line can cause fuel to leak [A] or the hose to
burst. Remove the fuel tank (see Fuel Tank Removal in
the Fuel System chapter) and check the fuel hose.
Replace the fuel hose if any fraying, cracks [B] or bulges
[C] are noticed.
Check that the hoses are securely connected and clamps

•

are tightened correctly.
When installing, route the hoses according to Cable,

•

Wire, and Hose Routing section in the General Informa­tion chapter.
When installing the fuel hoses, avoid sharp bending, kink-

•

ing, flattening or twisting, and route the fuel hoses with a
minimum of bending so that the fuel flow will not be ob­structed.
Replace the hose if it has been sharply bent or kinked.

PERIODIC MAINTENANCE 2-17

Air Cleaner Element Cleaning and Inspection

NOTE

In dusty areas, the element should be cleaned more

○

frequently than the recommended interval.
After riding through rain or on muddy roads, the element

○

should be cleaned immediately.

WARNING

Clean the element in a well-ventilated area, and
make sure that there are no sparks or flame any­where near the working area. Because of the
danger of highly flammable liquids, do not use
gasoline or a low-flash point solvent to clean the
element.

2-18 PERIODIC MAINTENANCE

Maintenance Procedure

Remove the element assembly from the air cleaner hous-

•

ing (see Air Cleaner Element Removal in the Fuel System
chapter).
Separate the element [A] from the element holders [B].

•

Clean the element in a bath of high-flash point solvent,

•

and then dry it with compressed air or by shaking it.
Visually check the element for tear or breaks.

•

If any of the parts of the element are damaged, replace
them with a new one.

After cleaning of the element, saturate it with high quality

•

form air filter oil and squeeze out excess oil.
Wrap the element [A] in a clean rag [B] and squeeze it as

•

dry as possible.
Assemble the element with the holders, and install them

•

into the air cleaner housing.

Cooling System

Coolant Level Inspection

Situate the motorcycle so that it is perpendicular to the

•

ground.
Check the level through the coolant level gauge on the

•

reservoir tank [C]. The coolant level should be between
the "H" (High) [A] and the "L" (Low) [B] level lines.

NOTE

Check the level when the engine is cold (room or ambi-

○

ent temperature).

If the coolant level is lower than the "L" (Low) level line,
add coolant to the "F" (Full) level line.

CAUTION

For refilling, add the specified mixture of coolant
and soft water. Adding water alone dilutes the
coolant and degrades its anticorrosion properties.
The diluted coolant can attack the aluminum en­gine parts. In an emergency, soft water alone can
be added. But the diluted coolant must be returned
to the correct mixture ratio within a few days. If
coolant must be added often, or the reserve tank
has run completely dry, there is probably leakage
in the cooling system. Check the system for leaks
(see Visual Leak Inspection, and Cooling System
Pressure Testing).

Maintenance Procedure

Radiator Hoses and Connections Inspection

The high pressure inside the radiator hose can cause

○

coolant to leak [A] or the hose to burst if the line is not
properly maintained. Visually inspect the hoses for signs
of deterioration. Squeeze the hoses. A hose should not
be hard and brittle, nor should it be soft or swollen.
Replace the hose if any fraying, cracks [B] or bulges [C]
are noticed.
Check that the hoses are securely connected and clamps

•

are tightened correctly.

Engine Top End

Air Suction Valve Inspection

The air suction valve is essentially a check valve which
allows fresh air to flow from the air cleaner into the exhaust
port. Any air that has passed the air suction valve is pre­vented from returning to the air cleaner.

Remove the air suction valves.

•

Visually inspect the reeds [A] for cracks, folds, warps,

•

heat damage, or other damage.

If there is any doubt as to the condition of the reed, replace

the air suction valve as an assembly.

Check the reed contact areas [B] of the valve holder for

•

grooves, scratches, any signs of separation from the

holder, or heat damage.

If there is any doubt as to the condition of the reed contact

areas, replace the air suction valve as an assembly.

If any carbon or other foreign particles have accumulated

•

between the reed and the reed contact area, wash the

valve assembly clean with a high flash-point solvent.

PERIODIC MAINTENANCE 2-19

CAUTION

Do not scrape off the deposits with a scraper as this

could damage the rubber, requiring replacement of

the suction valve assembly.

Valve Clearance Inspection

WARNING

Be sure that the outer cable end at the clutch lever
is fully seated in the adjuster at the clutch lever, or
it could slip into the place later, creating enough
cable play to prevent clutch disengagement.

After the adjustment is made, start the engine and check

•

that the clutch does not slip and that it releases properly.

Wheels/Tires

Air Pressure Inspection/Adjustment

Measure the tire air pressure with an air pressure gauge

Tire Tread Wear Inspection

As the tire tread wears down, the tire becomes more sus­ceptible to puncture and failure. An accepted estimate is
that 90% of all tire failures occur during the last 10% of tread
life (90% worn). So it is false economy and unsafe to use
the tires until they are bald.

Measure the tread depth at the center of the tread with a

2-24 PERIODIC MAINTENANCE

Maintenance Procedure

Wheel Bearing Damage Inspection

Using a jack and attachment, raise the front wheel off the

•

ground (see Wheels/Tires chapter).

Turn the handlebar all the way to the right or left.

•

Inspect the roughness of the front wheel bearing by push-

•

ing and pulling [A] the wheel.

Spin [B] the front wheel lightly, and check for smoothly

•

turn, roughness, binding or noise.

If roughness, binding or noise is found, remove the front

wheel and inspect the wheel bearing (see Hub Bearing

Inspection in the Wheels/Tires chapter).

Spoke Tightness and Rim Runout Inspection

Spoke Tightness Inspection

Check whether all the spokes are uniformly tightened.

•

Uniformly tighten the spokes if any spoke is loose or un-

evenly tightened.

Torque - Spoke Nipple: 3.0 N·m (0.3 kgf·m, 26 in·lb)

(On and after EJ650-A3/C3): 5.1 N·m (0.52 kgf·m,

45 in·lb)

Inspect the rims.

•

WARNING

If any spoke brakes, it should be replaced immedi-

ately. A missing spoke places an additional load on

the other spokes, which will eventually cause other

spokes to break.

Rim Runout Inspection

Raise the front/rear wheel of the ground.

•

Special Tool - Jack: 57001-1238

Check the rim for damage or warpage.

•

If there is any damage to the rim, replace the rim.

Measure the radial [A] and axial [B] rim runout by placing a

•

dial gauge against the sides and the outer circumference

of the rim, and slowly rotating the wheel.

Rim Runout (with tire installed)

Standard:

Axial Runout

Radial Runout

Service Limit:

Axial Runout

Radial Runout

0.5 mm (0.02 in.)

0.8 mm (0.03 in.)

1.5 mm (0.06 in.)

1.5 mm (0.06 in.)

If rim runout exceeds the service limit, inspect the hub

bearings. If the problem is not due to the bearings,

retighten the spokes.

WARNING

Never attempt to repair a damaged wheel part. If

the wheel part is damaged, it must be replaced with

a new part.

NOTE

Check the slack with the motorcycle setting on its side

○

stand.
Clean the chain if it is dirty, and lubricate it if it appears

○

dry.

Check the wheel alignment (see Wheel Alignment Inspec-

•

tion/Adjustment).
Rotate the rear wheel to find the position where the chain

•

is tightest.
Measure the vertical movement (chain slack) [A] m idway

•

between the sprockets.
If the chain slack exceeds the standard, adjust it.

Chain Slack

Standard: 35 ∼ 45 mm (1.4 ∼ 1.8 in.)

PERIODIC MAINTENANCE 2-25

Drive Chain Slack Adjustment

Remove:

•

Cotter Pin [A]

Loosen:

•

Axle Nut [B]
Chain Adjuster Locknuts [F] (both sides)

Turn the chain adjusting nuts [C] forward or rearward un-

•

til the drive chain has the correct amount of chain slack.
To keep the chain and wheel properly aligned, the left ad­juster mark [D] position should align with the same grad­uation that the right adjuster mark [E] position aligns with.

WARNING

Misalignment of the wheel will result in abnormal
wear and may result in an unsafe riding condition.

Tighten both chain adjuster locknuts securely.

•

Tighten the axle nut (see Front/Rear Wheel Installation in

•

the Wheels/Tires chapter).

Torque - Rear Axle Nut: 108 N·m (11 kgf·m, 80 ft·lb)

Insert a the new cotter pin [A].

•

NOTE

When inserting the cotter pin, if the slots in the nut do

○

not align with the cotter pin hole in the axle shaft, tighten
the nut clockwise [A] up to next alignment.
It should be within 30 degree.

○

Loosen once and tighten again when the slot goes past

○

the nearest hole.

2-26 PERIODIC MAINTENANCE

Maintenance Procedure

Bend the cotter pin [A] over the nut.

•

Turn the wheel, measure the chain slack again at the tight-

•

est position, and readjust if necessary.

Check the rear brake.

•

Wheel Alignment Inspection/Adjustment

Check that the left adjuster mark [A] position should align

•

with the same graduation [B] that the right adjuster mark

position aligns with.

If they do not, adjust the chain slack and align the wheel

alignment.

NOTE

Wheel alignment can also be checked using the

○

straightedge or string method.

WARNING

Misalignment of the wheel will result in abnormal

wear, and may result in an unsafe riding condition.

Drive Chain Wear Inspection

Remove:

•

Chain Cover

Rotate the rear wheel to inspect the drive chain for dam-

•

aged rollers, loose pins and links.

If there is any irregularity, replace the drive chain.

Lubricate the drive chain if it appears dry.

Stretch the chain taut by hanging a 98 N (10 kg, 20 lb)

•

weight [A] on the chain.

Measure the length of 20 links [B] on the straight part [C] of

•

the chain from the pin center of the 1st pin to the pin center

of the 21st pin. Since the chain may wear unevenly, take

measurements at several places.

If any measurements exceed the service limit, replace the

chain. Also, replace the front and rear sprockets when the

drive chain is replaced.

Drive C hain 20-link Length

Standard: 317.5 ∼ 318.2 mm (12.50 ∼ 12.53 in.)

Service Limit: 323 mm (12.7 in.)

Maintenance Procedure

WARNING

If the drive chain wear exceeds the service limit, re­place the chain or an unsafe riding condition may
result. A chain that breaks or jumps off the sprock­ets could snag on the engine sprocket or lock the
rear wheel, severely damaging the motorcycle and
causing it to go out of control.
For safely, use only the standard chain. It is an end­less type and should not be cut for installation.

Drive Chain Lubrication

If a special lubricant is not available, a heavy oil such as

•

SAE 90 is preferred to a lighter oil because it will stay on
the chain longer and provide better lubrication.
If the chain appears especially dirty, clean it before lubri-

•

cation.

[A] Apply oil

PERIODIC MAINTENANCE 2-27

CAUTION

The O-rings between the side plates seal in the lu­bricant between the pin and the bushing. To avoid
damaging the O-rings and resultant loss of lubri­cant, observe the following rules:
Use only kerosene or diesel oil for cleaning an O

-ring drive chain.
Any other cleaning solution such as gasoline
or trichloroethylene will cause deterioration and
swelling of the O-ring.
Blow the chain dry with compressed air immedi­ately after cleaning.
Complete cleaning and drying the chain within 10
minutes.

Apply oil to the sides of the rollers so that oil will penetrate

•

to the rollers and bushings. Apply the oil to the O-rings so
that the O-rings will be coated with oil.
Wipe off any excess oil.

•
