Description
Overview:
This crankcase-side oil seal is a Genuine Stihl part for professional cut-off saws, including the TS 410 and TS 420. It is designed to seal the crankshaft where it passes through the crankcase, helping to prevent oil and fuel/air leakage and to maintain correct crankcase pressure. The seal is made from a durable, oil- and heat-resistant elastomer with rigid reinforcement for stability and long service life in dusty, high‐load environments. A precise fit ensures reliable seating and consistent performance. It is a practical replacement during routine servicing or an engine rebuild, helping to restore smooth running, easy starting, and reduced seepage. Stihl reference: 9630 951 1696.
