Description
Overview:
This exhaust rocker arm is a genuine Lister Petter component for Petter PJ series diesel engines. Made from durable metal with a robust, machined finish, it transfers motion from the pushrod to the exhaust valve to open and close the valve accurately. Correct rocker action helps maintain valve timing, compression, and smooth running. Suitable for restoration, servicing, or repair, it is an unused vintage stock item that may show light tarnish or storage marks without affecting function. Designed for direct replacement of worn or damaged parts, it helps protect the camshaft, pushrods, and valve gear from accelerated wear. Ideal for use on compact industrial and agricultural machinery powered by Petter engines, including PJ1 and PJ2 models.
Key Features:
- Genuine Lister Petter part for assured fit and compatibility on PJ series diesel engines
- Purpose-built for exhaust valve operation to maintain reliable timing and performance
- Durable metal construction designed to withstand cyclic loading and high temperatures
- Direct replacement to restore correct valve lift and reduce valve train noise and wear
- Unused old stock (vintage) that may show tarnish or dust from storage only
- Suitable for routine maintenance, rebuilds, or engine restoration projects
- Helps improve starting, emissions control, and overall engine efficiency when replacing a worn rocker
- Straightforward installation using standard workshop tools (no modifications expected)
- Supports long service life when paired with proper lubrication and valve clearance adjustment
- Manufacturer reference: CB15 for easy identification
Typical Applications:
Used during top-end servicing, overhaul, or restoration of Petter PJ diesel engines found in generators, pumps, compressors, mixers, and other plant and agricultural equipment. Ideal when addressing poor starting, misfiring, noisy valve gear, or inconsistent exhaust valve actuation caused by a worn, cracked, or seized rocker arm.
