Description
Overview:
The Valve Spring Collar Exhaust is a genuine JAP component designed for the JAP 444H and 444H-2 industrial engines. It sits at the top of the exhaust valve spring to locate and retain the spring securely, helping to maintain correct valve timing and smooth engine operation. Manufactured from durable steel with a precise OEM profile, it withstands the heat and repetitive loads found in the exhaust valve train. This collar is suitable for engines used in industrial equipment such as site generators, pumps and concrete mixers. Supplied as unused old stock, it may show minor cosmetic ageing such as tarnishing, but this does not affect performance. OEM reference 29089 supports straightforward identification and like-for-like replacement during routine servicing or restoration work.
