Just swapping cams and stuff around today.

Quick question, if the cam sprocket drops just enough so that I can't get it back on the cam, can I just wind the tensioner out and back in again to get it on.
Or do I have to do the whole reset process?

Any help much appreciated, cheers.
Dave.

how far has it dropped,,releaseing the tensioner would be the safest way.

Oh only a couple of mm.
I found that by winding it out a couple of turns I was able to get the sprocket back on.

But I'm wondering whether it will be safe to do back up, or If I should release it all and do it properly.

for the love of god reset it!

The tensioner not only extends out on a spring, but does so incrementally. Once its out so far, it will not go back in the same distance. If you've ever had it out, you'll see that it extends in a ratchet like manner, and needs to be rotated in order to get it fully seated again. This prevents chain slap on very worn engines, but allows the spring to give it initial tension.

If you tighten up the cam, you risk breaking something, and if you don't, the chain will have too much tension on it and start tearing into the guides.
