S&S Pinion Shaft Bearings

4 products — part of all Pinion Shaft Bearings

S&S pinion shaft bearings for Harley-Davidson provide precision-grade replacements for the bearings that support the pinion shaft within the engine crankcase, enduring the constant rotational loads and thermal cycling of the V-twin. The pinion shaft bearing supports the right flywheel assembly and is a high-load crankcase component — wear introduces flywheel runout, increasing vibration, reducing primary chain alignment accuracy and eventually risking catastrophic crank failure. S&S Cycle engineers their Harley-Davidson pinion shaft bearings to tighter dimensional tolerances than OEM, with load ratings matched to the demands of stock and modified Big Twin engine builds. Correct bearing specification is critical during any crank rebuild — S&S provides the dimensional confidence that a precision engine assembly requires. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks S&S pinion shaft bearings. Browse the full S&S Pinion Shaft Bearings range below.
