Description
Overview:
This tab washer is a Genuine Lister Petter part for securing the extension shaft on classic Petter diesel engines. Made from durable metal, it locks the shaft nut or bolt in place by bending the tab against a flat, helping to prevent loosening from vibration and normal running loads. It is intended for PJ-series stationary engines, including PJ3 and PJ4, and supports reliable operation in long service intervals. Supplied as unused vintage stock, it can show minor storage marks that do not affect function. Identified by MPN CC90A, it offers a straightforward, correct-fit solution for routine maintenance or full rebuilds where the extension shaft assembly must be held secure to protect the engine and driven equipment.
Key Features:
- Genuine Lister Petter part for correct fit and function on PJ-series engines
