Gearbox output shaft oil seal
Just wondered if anyone could help please?
Gearbox is leaking oil into swinging arm on my 1990 R100GS.
I need to replace the output shaft oil seal therefore.
Can I bang a new one in from the outside i.e. without splitting the gearbox, or does it have to be replaced from the inside, necessitating opening the gearbox to get to the inside of the gearbox cover? Am hoping won't have to open the gearbox as it involves heating etc.
Would really appreciate any know-how on this.
