Description
Overview:
This inlet valve rocker is a Genuine Lister Petter part for Petter PAZ diesel engines, designed to restore accurate valve timing and smooth running. Built from robust metal for long service life, it transfers motion from the pushrod to the inlet valve, maintaining correct lift and duration under working loads. As a direct-fit replacement for the original rocker on PAZ engines, it helps recover compression, starting performance, and fuel efficiency after wear. Supplied as unused old stock, it may show light tarnishing that does not affect function. Identified by MPN ZPB 20, it suits engine rebuilds, routine maintenance, and preservation of vintage plant using Petter PAZ units.
