A/C, power steering, and fan (water pump/alternator) belts

[timsrv]

I've changed that bearing a few times. It's been a while, so I don't remember all the details, but I don't think it needed any pressing. I think it just pops out and the new one pops right back in. That bearing is used a lot on motorcycles, so if Napa doesn't have one a motorcycle shop should. Good luck. Tim

So i am in a similar spot as some of the other folks in this thread where in i need to get my hands on a new power steering drive belt idler assembly.. Long story short i was driving and my water pump / alt belt snapped, I managed to get the van home and went to remove the front power steering belt to get access to the rear alt belt and after loosening the pulley bolt i was still having a really tough time backing off the adjustment bolt on the tensioner.. a few tries and i snapped the bolt off in it .. Then wasn't able to drill it out either so looks like I need a replacement..

Hope you don't mind, I grabbed the pics from page 1 of this thread to help illustrate the part I am looking for .. If anyone has one in a parts pile, parts van etc .. id really appreciate the chance to buy one from a member here.. There is only one van in norcal at the yards at the moment and that is all the way up in Sacramento.. The way things are with work n kids at home at the moment.. well, its a stretch to think ill get a whole day to make that drive .. needless to say its a gamble if that one van even has the part still...



I am really hoping i can get the van back on the road soon .. I recently added a rear bumper with tow hitch and have been using the van to launch my tin boat at my local marina been sneaking away for a couple hours with my son on the Petaluma river a couple days a week .. he (and I) are really missing it ..

Well small update . I actually managed to drill out the busted bolt and re-tap the belt tensioner .. I am going to re-assemble tomorrow and see how it looks .. I may still be interested in a replacement depending on how well it goes together if anyone out there has a lead ... but fingers crossed this goes back together and looks like it will hold up.

What's the length and thread of the long vertical bolt on the idler pulley? I remember Tim posting it somewhere but I cant find it for the life of me...

EDIT: GOT IT - M8 x 1.25 x 90

Tim et al.,
Looks like the best post to add to instead of starting a new one. Having trouble with the alignment of my pulleys. Specifically the AC compressor (see attached pic). It is about one-half pulley width offset to the adjacent tensioner pulley. With the AC compressor bracket bolt-on design, it doesn't look like there's a possibility to shim anything here. Any thoughts or suggestions? I'm concerned about belt failure with such a drastic offset over a short distance. Note that the tensioner pulley and associated crank pulley are pretty close to being aligned.

More importantly, what is the pressure rating for that fuel filter, fuel hoses, and the clamps? Normal operating pressure for the van's fuel system is ~ 40 psi and that stuff looks to be only rated for ~ 5 psi. If any of that springs a leak things can get very exciting in a bad way. Especially if it blows all at once in a hot engine bay on a hot day.

Regarding the AC alignment, I didn't know it was possible, but it looks like the AC compressor pulley is installed backwards. Check out this pic from one of my parts vans:

Thanks, Tim. Fuel line is 30R7 with a 200+ psi rating, same as the remote filter (not pictured). Added the clear filter just to see what the gas looks like. Thanks for the reminder, that wix filter doesn't have a high psi rating, so I decided it was best to remove it. 👍

Thanks for the compressor pulley pick. You are correct, it's not possible to install backwards. Looks like the pulley is pressure fit around the clutch pulley core. I think it must've gotten hot and slipped back? Tried to torch it and press it back to position with no luck. Found that the '86- '88 vans offer a separate clutch pulley #88412-22030 potentially available for purchase at a few places. Still trying to figure out the difference between the '86-88 compressors vs the '89, but it's not clear. Any insight?

The extent of my AC knowledge is pretty much all here in THIS THREAD. It's a long thread (11 pages), but there is some good info and part numbers, so you should take some time to scan/review. On page 4 I made a post that shows the part number for the compressor in my picture above.
