Fan belt shredding

[officertyo]

Ok, i have finally got my 71 1900 wagon on the road and have been driving it for the past 2 months or so. I seem to have a problem with the belt that is just down right driving me nuts. The edge of the belt keeps shredding away and making the belt loose. I am on my third belt now, this one being one of those heavy duty agricultural belts and its doing the same thing. I have cleaned all the grooves in all the pulleys of rust and all pulleys seem to be in line. Has anybody else on here dealt with this and what did you do to fix it?

Just to clarify the belt is not being streched its being worn away on the sides of the "V" the ride in the grooves of the pulleys.

Thanks Ron

I had the same problem in my GT. For some reason the alternor was out of alignment. I solved the problem by adding washers, or spacers, to the alternator.

MOST LIKELY THE PULLEY ON THE CRANK AND THE PULLEY ON THE ALTERNATOR ARE NOT IN LINE. If you stand by the side of the car and sight inline with the belt you should be able to detect the misalignment. Probably the alternator needs to be shimmed towards the front or back. It is possible, but not as likely that the crank pulley is loose. Check the large 19mm? bolt that holds in on the crank to make sure it is tight. If so then you must move the alternator. I have had the same problem and may be caused by worn rubber bushings that hold the alternator.

I was thinking the same thing on the rubber bushings. Maybe they are just worn out. Is there any way to just get rid of them and mount the alt solid?

Some people replace them with ali bushes - but it is probably better to use Nolathane suspension bush material to keep a bit of flexibility and vibration isolation in the mounting system. Use one of the harder grades (black?)
