Counter shaft oil seal

(1/2) > >>

TwiggsiiieS:
Can anyone tell me if this seal can be replaced without splitting the crankcase, its the one behind the front chain sprocket.
The schematic seem to show a locating pin on the top. Seems like this could be common problem but I can't find any threads, so sorry if I've missed it and thanks in advance. Its a 1978 400f

MCTID:
Hi....check out the recent post from Roy Hall......I'm sure that he had a problem with a seal on his 350F, but managed to replace it without any drama.

Not sure if it's the same seal as yours.....but it might well be.

Good luck anyway.

Chris400F:
I was thinking about Roy's thread too (http://www.sohc.co.uk/index.php/topic,9636.0.html) but it was for a different seal.
Might be the same principle though, worth a read.

Bryanj:
Proper location of the peg is vital to bearing life so you have to split the cases mate sorry

TwiggsiiieS:
Thanks all, have only just got the bike and want to ride it a bit( well alot) before I pull it to bits. Yes Royhalls thread is very smilar but different seal. I will re read the whole thread again. Dont know how to go back to it while replying but i remember someone mentioning "opening the crankcase a tadge" is this doable in situ?I think I will buy a seal just to what it looks like.
