For installing all mechanics gearbox parts we recommended to use professional services!
If you decide on a home made installation of any gearbox parts it is equal with losing your warranty on a given part!
The warranty on gearbox parts is valid when a given part was installed by our authorized service. We remind that when a replica was bought in our shop, the installation of parts is free.
All parts (e.g. gearbox or external parts) bought and installed in our service contain the 3-month warranty.
