Description
Overview:
This genuine BSA tappet (OEM No. 86 2543) is a precision-made valve train component for the BSA 120CC industrial engine. Manufactured from durable metal, it transfers motion from the cam to the valve gear, helping to maintain correct valve timing and smooth running. It is suitable for maintenance, repair, and restoration of vintage BSA stationary engines used in industrial and light plant settings. Supplied as unused old stock, the part may show cosmetic ageing such as light tarnish or storage marks, but remains fully serviceable. A correct, like-for-like replacement, it supports reliable operation when installed and adjusted to the clearances specified in the engine manual, helping to reduce valve train noise and wear while protecting overall engine performance.

Typical Applications:
Used during valve train repair or overhaul on BSA 120CC industrial engines, including routine clearance adjustment, cam and follower replacement, and noise or wear diagnosis. Common in restoration projects where maintaining original specification is important. Suitable for engines powering small plant and stationary equipment found in workshops, agriculture, construction sites, and general industrial settings.
