RH Crank Oil Seal

[Guest]

After damaging TWO new seals (let them sit in the freezer overnight too) because I couldn't get the darn things in. Looking for advice, I've read people will use PVC, or large sockets and a bolt to draw them in?

Fortunately the previous owner didn't install a new one correctly, it was sticking out of the bore and slathered in RTV... no wonder it was leaking behind the ignition cover.

What's your method of choice? Any tips?

EDIT - 1980 GS550

I've not no idea what kind of bike you have but regardless, the crank seal is to be installed while the crankcase is split. If you are trying to drive the seal in on a built engine it's difficult. Only thing I can think to suggest is to lube the OD of the seal with something like Threebond 1184. You can try loosening up some of the crankcase screws in the general area but that may cause issues later so use that technique as a last resort.

I have heard of people chamfering the bore in the cases slightly to ease the installation. Dar

Sorry, its a 1980 GS550. I did put the 1184 on the OD but they did not want to go in straight . I was nervous about messing with the case bolts and causing future leaks. I think this is the last one left after chasing a few for the last few months.

Good idea, I read that one was well. have to be very careful not to get any metal in that bearing though.
