OLEO-MAC GSH400 Chainsaw Oil Drive Pump Cover & Screws

Oil drive pump cover with screws fits Oleo-Mac GSH400 and many other chainsaws. The cover encloses the oil pump mechanism against the crankcase, keeping the pump’s internal plunger or rotor correctly seated while the screws hold it firmly clamped in place. When the cover cracks, warps, or its screws work loose or strip, the pump housing can no longer seal or sit correctly, which may let the pump’s drive slip out of alignment or allow oil to seep out around the joint instead of being delivered to the guide bar. Fitting a replacement cover with screws restores a secure, correctly seated oil pump housing.
