Gudgeon Pin for Piston Fitted to Villiers MK25 Engines – OEM No. 30961

Description

This Gudgeon Pin (OEM No. 30961) is a Genuine Villiers part designed for the MK25 engine. The pin links the piston to the connecting rod, allowing smooth pivoting through the engine cycle under high load and temperature. Made from hardened, precision-ground steel for strength and wear resistance, it is built to maintain correct alignment and motion of the piston. Suitable for Villiers MK25 engines commonly found in construction and garden machinery, it serves as a direct replacement to restore reliable operation. As unused vintage old stock, the pin may show light tarnishing or storage marks, but this does not affect performance. Use it to keep classic Villiers-powered equipment running correctly and to maintain original specification and fit.
