®
T111 Engines are designed and intended for
S&S
installation in a stock Harley-Davidson
®
Twin Cam 88
chassis. It will bolt directly to the stock transmission and
engine mounts of chassis designed for stock Twin Cam 88
engines. The T111 Engine is available in silver powder
coat or black powdercoat finish.
Installation can be performed by any Harley-Davidson
repair shop equipped to do complete engine overhauls.
No special tools other than those used in normal engine
®
building operations are required.
®
NOTES
Installation of a fuel injected engine in a motorcycle that
was originally equipped with a carburetor is fairly difficult
®
and expensive. This conversion requires a fuel pump
equipped gas tank as well as wiring harness.
All S&S T111 assemblies are for Twin Cam 88
counterbalanced engine applications, and are not for use
®
in Twin Cam 88B
counterbalanced applications.

used on the completed engine.
2- Additional Features:
Greater overall strength than stock crankcases, especially
in the front motor mount, an important consideration in
high performance applications.
All oil passages between the crankcase and cam support
plate are O-ring sealed.
Compatible with stock components. Use stock oil pump,
cam support plate, gear cover, etc.

Uses 1999-2002 Timken
style sprocket shaft bearing.
Uses 2003-up pinion shaft bearing
®
T111 instructions often refer to procedures
S&S
described in other S&S instructions or a Harley-Davidson
Service Manual. These materials should be crossreferenced as necessary.

IMPORTANT
Before proceeding, verify that serial numbers on crankcases
match numbers on packing carton and certificate of origin.
Contact S&S immediately if numbers do not match.
NOTE - Valid certificate of origin is required for any transfer
or sale of longblock assemblies. Certificate of origin is
required to title and license any motorcycle which is to be
driven on public streets and highways.
®
3- Modification Notes
®
Cycle cautions against modifying these crankcases
S&S
due to the possibility of damaging or weakening them.
Modifying S&S crankcases in any fashion voids all
manufacturer warranties. Should the customer elect to
modify the crankcases regardless, it is imperative that
hey and the information tag attached to them be
t
inspected beforehand to confirm that the correct model,
style, bore size, etc. have been provided. The customer
must confirm that crankcases and related parts are correct
before assembling them or having them modified in any
manner, and assumes all liability for modifications.
Under no circumstance will S&S be held responsible for
xpenses related to the modification of any S&S part in
e
the event warranty service is required. Modified parts will
not be accepted for credit or exchange. This will apply
regardless of cause or fault: customer, retailer,
manufacturer, or other.
For further information, contact S&S Technical Services at
608-627-8324, FAX 608-627-1488 or e-mail
sstech@sscycle.com
NOTE - Modification includes but is not limited to appearance
changes such as painting, powdercoating, plating, and
polishing. Proper preparation for these procedures as well as
the processes themselves may require the use of polishing
compounds, chemicals or procedures that are potentially
harmful to crankcases.
CAUTION
Passages and internal cavities may become obstructed by
residues from materials used to polish, paint, plate or
powdercoat surfaces. Additionally, surface finishing
processes can damage critical machined surfaces. Any of
the above may cause premature wear, damage or failure
of other engine components as well as the crankcases
themselves.
Glass bead and polishing residues are abrasive and can be
difficult to remove from recesses and small passages.
Abrasive residues can cause oil contamination and
extensive engine damage. Engine damage caused by
powder coating, polishing, glass bead blasting, or other
modification will not be covered under warranty.
- Engine To Frame Assembly
4
The engine should be installed into the frame before
the ignition, fuel, exhaust, and oil system components
are installed.
Follow the engine to frame fitting below:
Engine to Frame Test Fit
NOTE - The engine must be fitted to the frame it is installed
into. It must rest squarely on its attachment points, and bolted
olidly to the frame without stressing the engine case at any
s
point.
CAUTION
Failure to correctly mount the engine can cause problems not
covered under warranty including but not limited to,
excessive vibration, driveline mis-alignment, and broken
castings.
- Test-fit instructions for T111 style cases with stock
A
1999-up engine mounts.
1- Clean frame engine mounts and carefully remove
any irregularities from mounting surfaces. Also
inspect crankcase mounting bosses for burrs.
2- Position engine in frame, check for clearance at
frame, and alignment to transmission. It is a
good idea to replace rubber engine mounts at
this time. Old mounts deform over time and can
induce unwanted stresses on the engine case.
Replace all other motorcycle components removed for
engine installation. Consult authorized Harley-Davidson
service manual for installation procedure for stock parts
not covered in S&S instructions.
NOTE- On certain models it may be necessary to switch the
shift linkage to the outside of the shift lever. Make certain
that there is clearance between the shifter rod and the engine
crankcases.
®
Powder Coating - Subjecting heat-treated alloys such as
those used in S&S crankcases to excessive heat can
drastically alter their strength and their critical properties.
The degree of change depends upon the temperatures
reached and the duration of exposure. When powder
coating or otherwise processing alloy parts, S&S exposes
them to a maximum temperature of 370°F for no longer
than 20 minutes. Under no circumstances should parts be
heated past 400°F!
S&S strongly recommends trial-fitting every engine
before frame is painted or powdercoated.
5
5- Ignition System Installation
A- All Carbureted S&S T111 assemblies come with an S&S
IST (Intelligent Spark Technology) ignition. Use of this
ignition system is highly recommended. All aspects of
ignition timing- advance, retard, and curves are
andled automatically by the S&S IST ignition.
h
B- Once the IST ignition has been installed per the
included instruction sheet 51-1155, no other
adjustments are necessary
NOTES
If the S&S IST ignition is not used, S&S recommends using
electronic ignition with adjustable advance curve in S&S
T111 engines. Adjustable curve permits slowing rate of
advance to control or eliminate pinging under heavy load
or when elevated temperatures or poor quality gasoline
encountered.
All other ignition systems other than the included S&S IST
ignition install per manufacturers instructions.S&S
recommends setting the total ignition advance to 28
degrees. Timing degree recommendations given by S&S
take precedence over the ignition manufacturers
instructions.
CAUTION
Timing that is too advanced will result in detonation and
engine damage. Timing that is too retarded will result in
engine over-heating and engine damage. (This caution
applies only to installations other than the S&S IST Ignition)
- Fuel system installation and tuning

®
Engine assemblies are available with either
1- Engine assemblies supplied with Super “E”
arburetors, refer to included instruction sheet
c
51-1012.
2- Engine assemblies supplied with fuel injection, refer
to included Induction System instruction Sheet.
1- Refer to appropriate service manual. Inspect fuel
lines and clamps - replace as necessary.
2- Check fuel line connections and routing. Avoid
hot surfaces. Make certain that the protective
cover has been placed over fuel line, and that it
is clear from sharp edges and abrasive surfaces.
3- Fill the fuel tank with a sufficient quantity of
gasoline for the initial start-up procedure.
4- Double check that all fuel line connections have
been made correctly and there is no gas leakage
at any point in the system.
CAUTION
If S&S determines that engine damage was caused by
improper ignition timing, repair will not be covered under
warranty.
Excessive ignition advance will cause engine to kick back
against the starter during start-up and “buck” when ridden at
steady speed with partial throttle. An advanced condition can
also cause pinging or ignition knock and possible piston
damage. These symptoms may not be noticed if electronic
ignition with “soft” advance curve is used.
Excessive ignition retard causes sluggish performance and
severe overheating with possible subsequent damage to the
engine, and must also be avoided. Immediate or rapid exhaust
pipe discoloration is usually a sign of retarded ignition timing.

NOTE - Make certain that the exhaust system is not preloaded, or in a bind, at the lower mounting points. Make all
spacing adjustments prior to final-tightening of the upper
exhaust mounting hardware at the cylinder heads. Failure to
follow this procedure may cause excessive vibration and result
in failure of exhaust pipes or mounting hardware.
- Initial Start-Up And Engine Break-In
9
NOTE - engines are designed for high performance and as
uch are not as tolerant of inadequate break-in as stock or
s
lower performance engines. Correct break-in will assure
longer engine life and will prevent unnecessary engine
damage. Engine damage caused by improper break-in is not
®
covered under the S&S
warranty.
A- Initial start-up
1- For the initial start up, the fuel and ignition
systems should be adjusted to their baseline
settings. (Baseline settings allow the bike to start
and run, and are the starting point for tuning.)
This is adequate for the initial start-up and heatcycling of the engine.
NOTE - Because there are several ignition and fuel system
®
combinations possible with the S&S
T111 engine, baseline
settings are not listed here. Refer to the appropriate ignition
or fuel system instruction sheet.
2- Run engine approximately one minute at 1250-
1750 rpm. DO NOT crack throttle or subject to
any loads during this period as head gaskets are
susceptible to failure at this time. During this
time, check to see that oil pressure is normal, and
that oil is returning the oil tank.
3- Shut off engine and thoroughly check for any oil
leaks, fuel leaks, or other problems. Let engine
cool to the touch.
4- After engine has cooled, start up again and allow
the motor to build some heat. Engine should not
be run longer than three to four minutes. When
the cylinders become warm/hot to the touch
(approximately 150°) shut the motor down and let
it cool to room temp. Follow the same cautions as
for the initial start-up, and continue to watch for
problems.
5- Repeat this procedure 3 or 4 times. Each
successive time it should take slightly longer to
warm up and you can increase the temperature
slightly each time. You can be more liberal each
time with the rpm, gently vary rpm continuously
from idle up to 2500 rpm in the final cycle. The
motor should not reach full operating
temperature during these cycles. Do not allow
engine temperature to become excessive.
. Engine break-in
B
1- Closely monitor engine for excessive heat build-
up. Do not allow the engine to idle for long
periods of time. Be especially watchful when air
emperatures exceed 90 degrees. Slow speed
t
operation in urban areas during the summertime
is especially hard on engines.. Temperature for
engine oil should be between 180º - 240º F. If
engine oil temperature stays above 220º F, and
correct ignition timing has been verified, S&S
Cycle suggests that an oil cooler be installed. Do
not run engine under conditions where oil
temperatures continue to remain high.
2- For the first 50 miles ride the motorcycle in a very
conservative manner. The first 50 miles are most
critical for new rings and piston break-in. Engine
damage is most likely to occur during this period.
Keep heat down by not exceeding 2500 rpm.
Avoid lugging the motor, riding in hot weather
or in traffic. Vary the engine speed. Do not lug
the engine. Change the oil at 50 miles. This will
remove the heavy accumulation of break in
residue from the oiling system.
3- The next 500 miles should be spent running
engine no faster than 3500 rpm or 60 mph.
Correct any obvious ignition or fuel problems, if
present. Avoid continuous steady speeds, and do
not lug the engine. Vary engine rpm. change the
oil again at 500 miles.
CAUTION
Lugging or running engine prematurely at sustained high rpm
may result in damage to pistons and other engine
components. S&S voids it’s guarantee if engine is not broken
in properly.
4- For the balance of the first 1000 miles the motor
can be run in a normal but conservative manner.
You can be more liberal with the rpm range and
motorcycle can be operated at normal highway
speeds. Avoid overheating or putting any hard
strain on the engine: no drag racing, dyno runs,
excessive speed, trailer towing or sidecar
operation.
5- After 1000 miles, verify Ignition and fuel system
settings and adjustments. Change the engine oil.
The break in process is complete.

A- Exhaust Systems
Muffled exhaust systems.
If you have an existing 2-into-2 system that uses slipon style mufflers, whether it is an OEM or an
aftermarket system, we recommend the new S&S slip-
®
on mufflers. S&S
dyno tests achieve almost 8 more
horsepower and 5 ft. lbs. of torque on a stock Harley-
®
Davidson
Twin Cam 88®engine using stock header
pipes and S&S slip-on mufflers, and S&S Super
®
Sidewinder
engines have produced 1-1.1
horsepower per cubic inch using stock style exhaust
and S&S slip-on mufflers. These mufflers will allow
your engine produce more horsepower and torque
than straight-through drag pipes in street and
highway driving, and work equally well on both stock
and large displacement engines.
Drag pipes
While drag pipes can be used with good results to
achieve top end horsepower, they are generally not
recommended for street applications. Carburetor
adjustment and jetting is generally easier for engines
with muffled exhaust systems.

B- Gearing
Gearing depends on the total weight of the machine
and rider, the size of the engine, cam, exhaust system
and type of riding. Most high performance engines,
and particularly those with larger displacements, are
capable of pulling more gear. We suggest you break
the engine in with stock gearing to minimize the load
on the engine. After the engine is broken in, you will
have a better feel of its potential and can change
gearing accordingly.
The following formula will determine final drive gear
ratio:
Engine Revolutions Per One Revolution of Rear Wheel=
(Clutch Sprocket*) x (Rear Wheel Sprocket*)
(Motor Sprocket*) x (Transmission Sprocket*)
*Number of teeth on each sprocket
