Description
Overview:
This Crankcase Tappet Bush is a genuine Jap OEM component for the JAP 55 CB Twin Industrial Engine, supplied under MPN 18612. It is a precision bush that supports and guides the tappet (cam follower) where it passes through the crankcase, helping to maintain correct valve timing and quiet, smooth operation. Typically produced from a durable bronze bearing alloy for wear resistance and stable oil film, it is well suited to the demands of vintage industrial engines. Designed specifically for JAP 55 CB and 55CB units, it is a direct-fit service part for restoration and maintenance. As unused old stock, the bush may show light storage tarnish that does not affect performance, making it ideal for authentic rebuilds where original specification matters.
