S&S Cycle 53-80 BT Oil Passage Drill Jig

The S&S crankcase oil passage drilling jig is used to perform crankcase drilling modifications when installing an S&S oil pump assembly on early big twin crankcases. Made of hardened steel for durability, this fixture enables the builder to do four modifications.

• Primary chain oil supply passage from the breather valve gear cavity to the back side of the oil pump body on late generator and early alternator crankcases


• Pressure relief passage from behind the main oil pressure valve to the gear cavity on alternator crankcases


• Crankshaft and main bearings supply passage on early alternator crankcases


• Crankshaft and main bearings supply passage on generator crankcases
