Modification Notes
S&S

Cycle cautions against modifying these crankcases

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
they and the information tag attached to them be
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
expenses related to the modification of any S&S part in
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.

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.

G 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.

G 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.

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.

Engine To Frame Assembly
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
solidly to the frame without stressing the engine case at any
point.

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
1999-up engine mounts.

Clean frame engine mounts and carefully remove
any irregularities from mounting surfaces. Also
inspect crankcase mounting bosses for burrs.

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.
