I did get my generator belt changed and fan belt back on- bit of a challenge- now the three nuts on the pulley I did loosen and it never moved more than 1/2" and now trying to get it to move back to tighten belt but not going- I would think it would move? Thanks.

It seems to me you could free it up by removing the 3 bolts and working but I would have to look at one to verify.

As Olliejunkie said, it will be necessary to remove the pulley and take the slip ring off. You may even need to rent a gear puller from Autozone or someplace to get the adjuster ring off without damaging it. Your pulley is probably beat up from previous adjustment actions. You will need to use various tools to smooth out the damage. My theory is that these pulleys were often adjusted while the tractor engine was hot (Probably overheated). To further speculate, the main part of the pulley was getting a lot of heat from the engine and expanding more than the adjustment ring which was exposed to moving air. This would effectively lock up the pulley assembly. I think this explains why you see so many pulleys on Fleetlines (66, 77, 88) beat up and difficult to adjust. Oliver had to stay with this design so they could fully cover the engine compartment with sheet metal. A typical single V-belt arrangement would often throw the generator into interference with the side panel.

I see and that's probably the way to do this- might be a rainy or snowy day before I get to it! I will have to remove the hood and the from metal and the radiator. Thanks.

Last one I did I took apart and either greased it or used anti sieze on it.
