Description
Overview:
This Crankshaft Pinion is a genuine BSA component for the BSA 120 cc industrial engine, supplied under OEM reference 86 2565. It is a precision-machined steel gear that mounts on the crankshaft and drives the engine's timing gear train, helping to maintain accurate valve timing and smooth running. Built for robustness and long service life, it supports reliable power transmission in stationary and site-used machinery powered by BSA industrial engines. As unused old stock, the part is new and unused but may show light storage ageing such as surface tarnish, which does not affect performance. Ideal for restorations, repairs, and routine overhauls, this pinion helps keep vintage BSA 120 cc engines operating efficiently in mixers, pumps, generators, and other small plant where dependable timing drive is essential.
