RE: [DML] Re: Alternator & WP Belt

Harold and group, 
With our 20+ year old V belt technology, A good V belt that will ride
moderately high in the grove is and 11A type ( 11mm wide at top) for the
alternator and WP and 13A ( 13mm wide) for the AC compressor. 
US manufactures are trying to cheapen the belts and making them thinner and
they are sitting further down in the grove. Stay away from them. You want a
belt that will be a little above the pulley 1/16th" or so and it should be
11MM across the top for WP and Alt and 13mm for AC belt. The Gates and Dayco
are normally running about 10.66mm wide . I have also found that Dayco is
selling a 10A belt to replace the 11A type and it won't work. They ride to
far into the grove and they will heat up and stretch and break real fast.
I have found a foreign made belt that is 4 Nylon plies with the new inside
teeth technology that will help it run cooler that is 11mm + wide. Looks
like a good belt and I have several people running them now.

P.S. I sent all the 10A Dayco back, but the Gates are or seem to be holding
up good.

Good question. The manual (M:04:01) says 6-10 mm with moderate thumb 
pressure from the top. So what is moderate and how do you measure 
the deflection? I use to do it with a long straight edge I had and I 
used a flat edge to deflect the belt.
