fitting the camshaft or not!

<< < (3/5) > >>

billdn:
Wish it was Peter , it's just a naff angle and my poor photographic skills. unfortunately it is round  :-\
John  - i thought i might try that but there doesn't even seem to be enough slack to persuade it off the sprocket - unless you have a nifty trick. i have tried it. my thoughts would be take off the chain, remove head and have a look inside - if i could just get that b****y chain of.! >:(

Would it not be easier to split the chain ?
Edit....my thought is based entirely on Women's logic by the way !!!!

Dave487:
Can you take the chain off the sprocket, then lay the camshaft into it's bearings with the sprocket fitted into the undercut next to sprocket boss, then wind the chain onto the sprocket and finally slip the sprocket onto its boss.
I think that's how I did mine.

Dave.

Front chain guide removed will give more room I think.
I ended up removing the rear slipper blade temporarily, being careful that the small location damper it sits in did not come out of the tensioner horseshoe at the same time.
From memory the chain was off the sprocket when fitting the camshaft.

mike the bike:
The camshaft has got to be on the head bearings, the sprocket off the shoulder on the cam to fit the chain and then lifted onto the shoulder.  To get the timing right it's got to come off the shoulder, moved on link by link until it's right then put back on the shoulder.
Hope this helps.
