I just became a member and a friend of mine said I could probably get some valuable info on trying this job myself.
Welcome to HEF, Chuck ! A 580L fan belt change is very much like the one rdavision is dealing with today in his thread.
Welcome to HEF @Chuck58 Remove the 4 x bolts at the pump coupling & slide the coupling away from the pulley.
I got the bolts out, but I can’t get the coupler to move more than a 1/16”. Any tips on how to get it to slide?
Lots of penetrating oil and keep working it back and forth. The splines dry out over time and can get so rusty they will lock up.
I ad to go down and buy a air chisel and a few bit. I cut the end off the one chisel, and with 3 guys and a lot of PB blaster, kreoil and some blood on the fan bases we finally got it to move. We celebrated with plenty mich ultra and Busch lites. It took me 2 hrs to get that coupler to move back but it finally did and I wanted to thank all on here for the advice and knowledge to make it a success. Thank you Guys!
