Technical Notes

This gasket seals the gearbox front cover to the transmission housing, helping to retain gearbox oil and prevent leaks around the front of the gearbox.

Whenever the front cover is removed for gearbox repairs or bearing replacement, it is recommended that a new gasket is fitted during reassembly. Both mating faces should be thoroughly cleaned and inspected for damage before installation to ensure an effective seal.

This gasket is specifically intended for single clutch tractors fitted with the 5 x 2 gearbox. If your tractor is fitted with a different gearbox or a dual clutch arrangement, please check the parts diagram or contact us before ordering to ensure you receive the correct gasket.
