Two "fan" belts on my 12A (80SA) build:
I didn't mark which belt is which. (*sigh*)
One is slightly larger than the other. Can anyone tell me which Belt drives which accessories?
!@#$%!

thanks

Thinking taking size of pulleys into account,larger belt would go around water pump/air pump.Do a trial fit and look at marks left on respective adjustment brackets by their tensioning hardware,should be real close to where they were previously.

 

Good thought - Longer run looks like the air-pump/w-pump...got a 50% chance of nailing it
my thanks...

Just installed dual-sheave pulley on my alternator, and that's correct - the slightly longer belt is for the Main, Waterpump, Air Pump run.

 

Thanks Duck! you are (both) correct and the belts are mounted and set. I know there are 'no dumb Qs' but this one was pretty close.
Now lets get on with helping folks with Real problems!
(some of which may still be mine as I get close to first-fire-up of rebuild 12A I am resurrecting here in Alaska as we speak...!)
