Under no circumstance will S&S® be held responsible for expenses related to the modication of any S&S part in the event warranty service is
required. Modied parts will not be accepted for credit or exchange. This will apply regardless of cause or fault: customer, retailer, manufacturer,
or other.

NOTE: Modication 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 nishing 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.
Powdercoating - 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!

NOTES
Valid certicate of origin is required for any transfer or sale of aftermarket crankcases or complete engines built with aftermarket crankcases. Certicate

of origin is required to title and license any motorcycle which is to be driven on public streets and highways.
S&S crankcases manufactured before Fall, 1998, require modication for use with 45 amp Harley-Davidson® alternator supplied on ‘97-up fuel injected

big twins and available as upgrade kit H-D® #29999-97. See Section 2, Final Preparation, for modication procedure. Performed correctly, 45 amp
alternator modication will not void S&S warranty.
*All reference to Harley-Davidson® part numbers is for identication purposes only. We in no way are implying that any of S&S® Cycle’s products are
original equipment parts or that they are equivalent to the corresponding Harley-Davidson® part number shown.
