I had the fan belt come off on my 2000 B2410 When a large snake got caught in it. Trying to get it back on is impossible. It's like it's to short. I get it around the drive pulley, the alternator pulley than it's to tight to go over the fan pulley. I loosen the alternator and moved it as close as I could but that still doesn't give it enough slack to fit. Anyone know the secret to getting it back on?
