Yanmar Tractor Hydraulic Screen O-Ring. This O-ring seals the hydraulic / transmission screen to the transmission housing. It goes up on the screen near the triangle plate.
How To Use: Carefully remove old gasket with a razor and steel wool. Do not scratch mating surfaces. Apply a THIN FILM of automotive silicone to both sides and follow manufacturer's directions. Do not apply so much that blobs form when tightening. These blobs can break off and clog tiny ports in your hydraulic system.
