Description
Overview:
This Genuine Husqvarna oil seal is a direct replacement for the lubrication and crankcase sealing points on selected Husqvarna petrol chainsaws, including the 435 and 435E. Built from an oil‐resistant elastomer with a rigid metal reinforcement, it keeps oil in and contaminants out, helping maintain correct crankcase pressure and reliable lubrication around the shaft and bearing areas. A precise fit to the OEM housing helps prevent air leaks that can affect starting, idling, and performance. Suitable for routine maintenance or engine rebuilds, it restores the sealing integrity needed for everyday cutting work. Manufacturer Part Number (MPN): 544 25 13 01, also referenced as 544251301.
