83 GS1100E RH crankshaft oil seal replacement?

Nothing stopping you from grinding a small lead-in taper on the rubber edge of the seal. I've used a bench grinder for this previously, a sanding/linishing belt would do it too. Only a small taper on the leading edge is needed.
Grimly's method of protecting the inner lips is a good one too.

Yeah that seems necessary, I could see just with pushing it in to test fit by hand that it was peeling back the outer shiny layer so I started to do that just a little, but stopped as I wasn't real comfy with it.

Sorry to bogart your thread Ron but good info here for all doing this job. Love that signature

Good info popping up here! I still haven't attempted replacing mine yet. Been working on getting other bikes running, and it only leaks when I ride it! LOL

If a person were to install this seal without splitting the cases, I would recommend filing or sanding a small chamfer on the leading edge of the seal bore. It will install easier and may not cut or scrape the seal. Dar

Agree. There was a thread here recently where a member was scheming on replacing a countershaft seal on his Triumph and putting a chamfer on the case was part of the process.

Thanks mine is in and no leaks, I tried re-installing the removed one as a dry run, and it was chewing it up, and the chamfer trick was just the ticket. I used a Dremel very lightly and then a 600 grit, with the bearing area sealed well with tape. I used this makeshift tool which is just a 2" PVC and some spare wood to push it in, and used the old seal as well in between as it just seemed like a better idea.

It got a bit dicey and I had to give some taps to straighten it out but I went slowly. Doing again I'd use a larger wood piece and employ the 3 outer cover bolt holes, that would allow fine adjustment (now I get it...!)
