Description
Overview:
The crankcase oil seal is a circular, lip-type seal fitted around the crankshaft to keep engine oil where it belongs and to protect the crankcase from contamination. This Genuine Stihl part (OEM 9640 003 1610) is made from a durable, oil‐resistant elastomer with a metal‐reinforced body to hold shape and grip the housing securely. It is designed for Stihl cut‐off saws and related machines, including the TS350 and TS360, and is essential for maintaining correct crankcase sealing for smooth running and reliable starting. By preventing oil leaks and air ingress, the seal helps protect internal components and supports consistent performance over long service intervals in both trade and DIY use.
