Description
Overview:
The Con Rod Bush Small End is a genuine JAP component for the small end of the connecting rod on JAP 4/3 engines. Made from a durable bronze alloy, it supports the gudgeon pin and maintains the correct running clearance, reducing friction and wear under load. This bush helps keep piston alignment stable and restores smooth operation in classic engines that have developed play at the small end. Supplied as vintage unused old stock (NOS), it is suitable for restoration work where authenticity and correct fit are important. OEM No. 6527 confirms compatibility with JAP 4/3 applications, and it is commonly used on JAP 3 and JAP 4 engines found in vintage machinery. Genuine JAP part for dependable fit and function.
