Cam out?

[Swiss Toni]

I’m replacing a gearbox bearing in a mates 1127 engine. I’ve been presented with the engine,  lower case removed. My question is; Is it a fiddle replacing the lower case around the lower protruding end of the front camchain tensioner? Will it locate ok in its pocket? Or, is it better to whip the exhaust cam out, and remove said tensioner???

C’mon! One of you hairy arsed OSSer’s  must have done it?

Crank cases come apart without removing the top end.

I know, Clive. Not what I’m asking.

Yep I trouble lining it back up so took a cam out .

@colinworth79Colin, I had to take all the gubbins out of the lower case to clean it out thoroughly. It was full of dust and black silicone. So, I put a dob of grease on the heel of the front tensioner, and offered the case up. Split the cases, and behold the pocket full of grease! Result! HAving said that, no selector forks to line up, so mightn't be such a success for real!

But it was! Straight in, no bother.

It's easy use a steel ruler to guide it into place

I've done few just splitting lowers never had issue, perhaps was lucky. I just made sure I went down square.
