Little advice needed..
It was easy getting the oil seal out, but I can't seem to get the new one in without damaging it ( I tried a few times )
After I got it out I heard that normally you need to split the cases...
I replaced a few of these before on other engines but never had a problem getting a new seal in with a little grease or oil.
Has anybody done this before? thanks!
