Description
Overview:
This Valve Spring is a genuine Kohler part designed to keep the engine valves operating with the correct tension for smooth, reliable running. Made from high-quality spring steel in a compact helical form, it maintains proper valve closing force to protect timing, compression, and performance over time. It is suitable for Kohler SV-series vertical shaft engines used in garden and light construction machinery, including models such as SV470 and SV480. As a direct replacement for OEM 20 089 03-S, it restores factory specification when servicing worn or weakened springs. Using the correct genuine spring helps reduce valve train wear, prevents valve float at working speeds, and supports clean combustion and easier starting. Ideal for both tradespeople and DIY users carrying out routine maintenance or repairs.
