Description
Overview:
This coupler for the decompressor shaft is a genuine Lister Petter part designed for the PJ series, including PJ2 and PJ3 engines. Made from durable metal, it links the decompression mechanism components so the system engages and releases smoothly during starting. A correct, rigid connection helps protect the valve gear and keeps timing consistent across the decompression cycle. Engineered for a precise fit on Petter PJ2, PJ3, PJ4, and PJW engines, it supports reliable starting and long-term operation, especially on older and restored engines. As an original component, it matches the manufacturer's specification for geometry and tolerances, helping to reduce vibration and premature wear. Robust even as stored old stock, it is a straightforward replacement for worn or damaged couplers.
