rear cover oil leak

Post by Barry Barker »



I have tried to find info/parts list on the rear cover, looks like it covers the main seal. I have a leak from this cover that has two bolts. Does the cover seal with an oring or a gasket? I can make a new gasket, have not had any luck finding a parts pic of this area to determine what might be wrong or old.

Got the carbs all back together and installed on the bike, should be able to try them out next week. Thanks for the reply's.

thanks for the info, but it is not the entire rear case, there is a small cover plate on the back of the rear case, it has 2 bolts and is about 4" in diameter. It looks to me to be a gasket, so i am going to pull the plate and just make a new gasket.

Thanks a bunch, the parts list will be helpful, I need to go and stare at the problem a little longer now. I didn't see the seal, Not much room in there with the swing arm and tire in place.

Let us know if this can be done with the engine in the frame. Some have suggested the engine must come out. The stator requires engine removal I believe.

Yes it can be done with the engine still in the frame. It will be easier if the bike was on a workbench or bike lift. Save working on knees.
Remove the clutch cable from the casing. Undo the lock nut and remove the washer. Remove the lever and spring. Now with a small spike push it into the oil seal and gently prize out the main clutch mechanism will stay in place.
Then get a socket the same diameter as the seal to help push it home once it is in place. Put back in reverse order re adjust clutch.
I have a gl1000 on the workbench so if you want some photos of the casing with the oil seal and lever just ask

once I got the oil changed and installed the correct amount, the oil leak has stopped. I think the crankcase was at least 1 1/2 quarts over full.
