Can't realign Cam Shaft Pulley

[shevik]

working on my bike tonight I attempted to replace the timing belts. When I took the belts off the right side cam pulley sprung forward. I think I attempted to turn it back into place without the T1 marker properly aligned on the fly wheel. Now when I have the T1 marker lined up I still cant get the pulley to move back to it's aligned position. What am I doing wrong here?

Hopefully you are doing all this with the spark plugs removed. That should make it much simpler.

The right side cam can be stubborn, there's a valve starting to open at TDC and the valve spring pushes the cam sprocket about two belt cogs CCW from the timing mark. You can turn it back but it fights.

For the right side belt, I simply use a wrench on the crank bolt and turn the crank a corresponding two cogs CCW, that way you don't have to fight the valve spring while getting that belt on. After the belt is on, you can turn the crank back to TDC (the T1 mark) and confirm the timing mark on the cam gear lines up correctly.

OK, I was able to figure it out. After temporarily misaligning the crank shaft and the right cam shaft I was able to finesse it by slowly rotating the fly wheel and the cam until they were realigned. I had to C-clamp it to get it to stay put. It wasn't as big of deal as I thought it was, I just needed to take a break and come back to it.

I'll usually use a clamp on the right cam pulley FIRST, before the belts come off, to avoid having it spring out of alignment like that.
