STIHL HS72 HS74 HS76 HS85 Gearbox Gasket

The Gasket Genius gearbox / gearcase gasket fits Stihl HS72, HS74, HS76 and HS85 hedge trimmers, replacing part number 4226 649 0300. The gearbox gasket seals the joint between the two halves of the gearcase at the cutting head, preventing gearbox grease from escaping during operation. When the gasket compresses or cracks, grease leaks from the gearcase joint, leaving the gear train running dry and accelerating wear on the drive teeth and blade crankshaft. Replacing it helps ensure the gearcase stays correctly sealed and the gear train remains properly lubricated throughout the working season.

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