parky265 Posted December 22, 2012 Report Share Posted December 22, 2012 A supplimentary question to the gear removal thread. Do I have to split the cases to change the crank seals or any of the other seals for that matter? If not then I'll be a happy man. Quote Link to comment Share on other sites More sharing options...
nh014 Posted December 22, 2012 Report Share Posted December 22, 2012 Replacement of the crankshaft seals does not require that the cases be split. Just remove the flywheel on one side and the clutch drive gear on the other side to gain access to the seal carriers. Previous advice on removing the drive gear is correct. It is a tapered fit to the crankcase and requires a good fitting puller. Don't bother with heat as the gear and the crankshaft are both steel and will expand at the same rate. Tighten the puller and give it a couple of goods raps with a hammer. Retighten and hit it again, then retighten and hit it again. Repeat until it comes loose. If you have access to an impact tool that may help. Quote Link to comment Share on other sites More sharing options...
