Sifton 45 Crank Pin for Harley G Models (1933–1942) with Dual Oil Feed Holes
The Sifton 45 Crank Pin (Part Number 10-1192) is a precision-fit, dual-oil-feed crank pin designed specifically for Harley Davidson G models from 1933 to 1942, delivering reliable lubrication and engine longevity.
Constructed from 8620 steel with a heat treatment depth of.062 inch, it features two oiling feed holes that accommodate both early and later flywheels. Its shorter length—approximately 0.025 inches less than the standard V-Twin 2-Hole Sifton Crank Pin—enables compatibility with a range of flywheel configurations.
Correct oil-feed alignment between the flywheels and the crank pin is critical for engine longevity and smooth operation. When installing, order the nut kit separately for secure assembly. For best results, use with the #10-1049 Truett & Osborne Flywheel Set. This part is manufactured in Taiwan to meet precise tolerances for vintage Harley restorations and rebuilds.
