Issue: have a full pressure 235 (originally from a car). I’m using a duralast 17430 belt. Ive burnt up 2 belts in 3 days.
Discussion: after the first V belt became a flat belt, I removed the belt and used my gun sighting laser to ensure my belts were aligned correctly. What I found was that I need to slide my alternator 1/8” forward to have it aligned almost perfectly. I replaced the belt and went for a test drive. During the test drive, I stopped and rechecked everything and thought I had the belt too tight. I loosened the belt very slightly. (I used a red paint marker to see how far I adjusted everything) when I got home, I found that the new belt doesn’t want to ride in the crank pulley. It was sitting on the front of the lip (just forward of the groove). The water pump numbers are the same car vs truck (same pulley width). The alternator pulley is the same width as a truck 235 (reused pulley from when I rebuilt my 261 and replaced the alternator).
Moving forward: I’m going to slide the alternator slightly back from the original position before I moved it. I’m also going to go the my local flaps to see if a narrower belt (duralast 15430) fits the grove better.
Questions:
Is a car 235 belt width the same as a truck 235 belt?
Are there other things I should consider?
Thanks gents any guidance you may offer.
Chris
