The chain tensioner/ roller assembly is held in place by a nut that IS the shaft the tensioner pivots on. A screw comes in from outside the case (by the brake disk) to hold the nut in place. This came loose, the screw moved out creating and oil leak and allowing the roller assembly to bang around inside the case, although it never completly fell of the screw (thank God).
When you try and tighten it all back up, the nut/shaft binds the pivot action of the tensioner assembly before the nut is tight. If you do not thighen it down you can turn the nut with one finger so it will surely come loose again. This could be a major disaster if the tensioner assembly falls down in the gear case. What to do? The dealer basicly say's leave it loose. I'm smart enough to know that is not a good idea.
Is there any reason NOT to grind/mill down the width of the "bushing" that rides on the nut/shaft to eliminate interference so the nut can be tighted down and the tensioner assembly still pivots?
