S&S Cycle

SUPER STOCK ® ALTERNATOR STYLE CRANKCASES

FITMENT • 1984–‘99 big twins under 4" bore

EO #D-355-8

FEATURES AND BENEFITS • Relocated cam chest oil pick-up increases gear case scavenging and virtually eliminates oil carry-over at sustained high speeds • Machined to accept the stock oil filter assembly used on 1992–’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. We recommend using both crankcase breathers in engines larger than 95" • Clearanced for strokes as long as 5" • Compatible with stock 1984-’99 flywheel assemblies, primary covers and gearcovers, making them perfect for stock replacement or high performance applications • Machined for installation of a crank position sensor. This allows the cases to be used in stock 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 • Exempt from emissions tampering regulations under CARB EO# D-355-8 when used with stock bore cylinders for 31/2" Bore (stock)

OPTIONS • Available for stock, 35/8", and 313/16" bore applications with deck heights as much as 3/16" taller than 31/2" stock

KIT CONTENTS • Crankcase assembly • All required hardware, fittings, and bearings

Two crankcase breather holes allows increased flexibility.

Relocated oil scavenge pick-up reduces oil carry-over by increasing oil scavenge efficiency.

NOTE: All S&S crankcases manufactured after June 1, 2008 do not have case interlock groove and ring and do not use case alignment studs. Case mating surface is flat, and cases are aligned with alignment dowels.
