Rear crankshaft seal qustion

[DasWaff]

Hey all, I'm putting my 'new' engine in my 86 GL-10 Turbo. I was replacing the rear main seal and in setting the new seal I accidentally tapped it in deeper, by about 3mm, than the old one. Is this going to bite me in the rump roast if I leave it? Now is definitely the time if I need to do it again. Thanks, DasWaff

I don't think a 3mm difference would be a HUGE deal. If the seal was cheap, I'm one of those anal people who would just redo it, but probably could leave it this way.

 

Is the crank itself new? I guess over time the original crank can actually get a slight groove worn in it from the old hardened seal. When the seal is replaced with the stock size, since the crank is fractionally smaller in the exact area where the seal rode, there are leaks since there is not a tight seal. This is not a given, but I have seen it before.

 

You are probably good. On the other hand, this is one of those cases where even though the chances of it being messed up are real small, the consequences of finding out we are wrong later are large enough that it would probably bother me to continue without just redoing it. It would suck to have to do it again after it was so easy at this point.
