3- 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

hey 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

xpenses 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.

 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.

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

olidly 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.

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.
