The Pump Piston Kit for Stihl MS192C chainsaws is a genuine Stihl replacement for the lubrication pump piston that drives chain oiling. Built from precision‐machined metal components for long service life, it restores correct oil delivery to the guide bar and chain, helping prevent premature wear and overheating. This kit is engineered for a precise, factory‐spec fit in the oil pump assembly of Stihl MS192C and MS192T machines, maintaining the reliability expected by professional users and homeowners. As an OEM Genuine Part (No. 1137 120 9701), it matches the original tolerances and performance, ensuring consistent operation after servicing. Use it when the chain runs dry, oil flow is weak, or the original pump piston shows wear, scoring, or sticking.
