anyone can help me ?
The beginning of this was lost in the mess-up a few days ago,but now I am looking for parts.
So here is a follow up to my belt wear problemo!!!
Well here I go again,I need your help again.I have analyzed and scrutinized my belt problem and I think I have identified the problem.I bought a set of Gates pulley and belt wear guages,and these have told me that the fan pulley is virtually un-worn,the guage for degrees of correct is designed to show sheave V wear at 3 different OS diameters.FYI>
For the B and BX belts a pulley diameter 3.60" to 4.56" dia. should be 32 degrees.
For the B and BX belts a pulley diameter 4.60" to 7.00" dia. should be 34 degrees.
For the B and BX belts a pulley diameter OVER 7.00 dia should be 38 degrees.
Using the guage I find minimal wear on the fan pulley ( over 7 inch) (this is good,I won't need to remove the radiator yet) the wear guage clearance in the fan pulley V's,is less or close to less than .005-.008
Using the guage I find severe wear on the adj,idler pulley in the 4.60" to 7.00" dia. range, the wear guage clearance in the V's is geater than .030-.050 per/on each side of the guage.
Using the guage I find severe wear on the angle drive pulley greater than the wear on the adjuster pulley.
So I quess what I need to know is who or where I can get these pulleys from, does anyone have spares,take offs or salvages ? At least these particular ones are more easily accessed.
The pulleys/belts with the most wear show that the pulley V's wear the belts mostly on the V side nearest the radiator which I will refer to as the outside.
The outside V's have more wear than the inside V's but still well worn.Thus perhaps the reason that the outside belt turned over in the groove.And the inside remained in the groove.
I THINK that the alignments are good.
Any Eagle fans, BusNuts or BCM folks got any suggestions.
PS. I am posting this on all the boards,THANX for any help.
