About S&S Cycle Special Application Crankcase

S&S Cycle Special Application Crankcase

  • Cam chest is moved outward. 250in. to allow crankcases to handle large cylinder bore sizes
  • Relocated cam chest oil pick-up increases gear case scavenging and virtually eliminates oil carry-over at sustained high rpm
  • Machined to accept the stock oil filter assembly used on 92-99 Big Twins
  • A ported breather passageway and a machined breather window allows the air/ oil mist to flow from the flywheel cavity to the cam chest of the engine with the least possible restriction
  • Crankcase venting can be achieved via two crankcase breathers, the cylinder heads, or both; S&S recommends using both crankcase breathers in engines larger than 95in.
  • Clearanced for strokes as long as 5in.
  • Machined for installation of a crank position sensor which allows the cases to be used in EFI applications and also allows easy installation of S&S IST Ignition and VFI Fuel Injection; a plug kit is included for applications that do not use a crank position sensor.
