I'm running a 4" pully and was wondering how many threads should be showing on the tensioner bolt, when installing a brand new belt. how tight should the you screw the pulley bolt? when checking the belt you use a 19mm wrench and turn the actual sc counterclock wise to see if the belt is installed correctly right? any input you have is greatly appreciated. thanks.
MMMmmm, Not a easy one....the thread count on the bolt is not a good way to gauge belt tension imo. I reach down and test belt deflection from the tensionor pulley to the crank pulley(under the motor mount). If it more than a 1/4 inch, time to tighten the belt. After you get the tension right, remember to get at least 50ft lbs on the 17mm pulley bolt.....or it will come off.
Ok cool. Is there a tool that is used to test belt tension? i'll have to make sure the pulley bolt is ok too, is it possible to over tighten the pulley bolt?
Its a grade 10.8, Its tough.....I have a 1 foot long 17mm wrench that I just lean on( I am not a small guy) and I have not had a issue.Originally Posted by si4life
Dude, you really don't need that tool. I did mine by using a 20in screwdriver and it never came off/loose. Just feel the tension of the belt as you're tightening it.
