Description
Overview:
The Outer Valve Spring for Lister Petter PD2 Range engines is a genuine OEM component designed to control valve movement and maintain correct seating throughout the engine's operating range. Made from high-grade, heat-treated spring steel, the helical coil construction delivers stable tension and long service life under continuous vibration and temperature cycles. As the outer spring in the PD2 valvetrain, it works with the inner spring (where fitted) to prevent valve float and ensure reliable combustion. This Genuine Lister Petter part (OEM No. FB57) is a direct-fit replacement for maintenance and repair on PD2 Range engines, helping to restore factory performance and smooth running. Suitable for professional workshops and DIY users working on generators, pumps, compressors, and other PD2-powered machinery.
