S&S Cycle Super Stock and Special Application Crankcases for 1936-99 Big Twin Engines - Manual (Page 2)

2
INTRODUCTION
Installation of S&S® Super Stock® crankcases for big twin engines is easy and can be performed by any v-twin repair shop equipped to do complete
engine overhauls. No special tools other than those used in normal engine building operations are required. S&S Special Application big twin
crankcases can be ordered for heavy duty street or race applications. Special Application crankcases ordered for street engines are very similar to
Super Stock cases and will be supplied with the same type of hardware. Special Application crankcases for racing engines are a special order part
and are machined to customer specifications, so hardware and installation requirements may vary. If Special Application cases are ordered without
an alternator cut out for racing, the alternator cut out cannot be machined afterward. All S&S Special Application crankcases must be used with a
special S&S pinion shaft 33-2040 which is .250” longer than stock.
NOTE: S&S crankcases are sold in matched sets only. Individual case halves are not available.

POLISHING, PAINTING, PLATING OR POWDERCOATING S&S CASES
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, year group, bore size, flywheel
diameter, oil pump mounting bolt hole pattern, 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.
