STIHL HS81 HS82 HS86 HS87 Gearbox Gasket

The Gasket Genius gearbox / gearcase gasket (no. 2) fits Stihl HS81(T), HS82(T), HS86(T) and HS87(T) hedge trimmers, replacing part number 4237 649 0302. The HS81/HS82/HS86/HS87 series uses two gearbox gaskets of different profiles within the gearcase assembly this is the no. 2 variant, distinct from the no. 1 gasket listed for the same models. A worn or damaged gearbox gasket allows gearbox grease to escape from the gearcase joint, leaving the gear train insufficiently lubricated and accelerating wear on the drive teeth and blade crankshaft.

A direct replacement that helps maintain proper gearbox sealing and reliable blade drive performance during use.
