chain tension.....how to adjust.

Whats the proper way to adjust chain tension?

Loosen lock nut and hand tighten?
I was told by another guy to turn in tight then back it off 1/2 turn?

Whats the right way to do it?

Turn it in finger tight, then back it off half a turn. Lock it down.

That will work but the best is to have the cover off and vissually see the chain. All you want is to be sure the chain has enough tension so that it doesn't hit the sides! If the chain is worn then even if you tighten it all the way down it could still hit?

Question Bad Chain Tensioner??

My chain case was rebuilt last year when the motor was rebuilt. I heard a slight noise so I checked chain tension. There's 170 miles on the new motor/chain case. I can hand tighten the tension bolt all the way in by hand.

I was told that is likely a bad tensioner. I'll be pulling the case open on Wednesday. What do I look for and how do I tell if it's the tensioner? If so what would I need to replace. (My service manual is still in the dang mail).

What did you replace?

If you didnt put a new chain in, do that. The one thats in there is stretched out.

If you have bottomed out the tensioner then the cain has streched? Open it up and see what is wrong! I hope you don't find what I found! This weekend my ZRT Blew up the chain case! I have to replace the whole thing as well as bearings and gears!

I think you will find that you only have a bad chain and they may look the same but when you put the new one on you will find that very little makes a big difference.

I just bought this. Chain and gears were replaced when the motor was completely rebuilt.
