I have an '87 BJ73 with 13B TD engine and 24VDC electrical system. My A/C compressor has locked up. Can anyone suggest a source for a replacement. The faulty compressor is a Denso 047200-8720. Other numbers on the tag are 0G-0026 and JOP15C.
 
Most AC shops can find you a comparable replacement, and then you'll have to use your 24v clutch or wire a converter and relay to operate a 12v clutch. Try part number 57389.
 
Hello Chevota3232,
We do have those compressors, they come with a 12V clutch coil, you may have to install you clutch assembly on the Denso compressor.

What all is involved in swapping the clutch coil? Any pics of the process?
 
Any thoughts on a replacement clutch for a BJ74?
(who might have one)

Actually not too difficult, especially if I can do it, which I just did a couple weeks ago. I had a 12v clutch with a relay center tapped from my 24v system from the PO. Ordered the appropriate 24v clutch from Amayama and switched them out to get my wiring in order. Only tools needed were snap ring pliers, appropriate sockets and a strap wrench to hold the pulley while loosening the nut. Loosen belt, remove nut/washer, pull clutch drive plate and spacers, remove snap ring, remove pulley, remove second snap ring, remove magnetic coil, replace coil then put back everything in reverse order. All of the above courtesy of ih8mud forum search.

I'm in Denver if you want a hand.
 
Took a little over a week. And $531-($350+$50)= $131.

Also, I didn't even look into US suppliers, just assumed 24v wouldn't be available:doh:

Should've contacted you, I guess:flipoff2:
 
The compressor I got from Coolstreamac came with a new 12V clutch.
The awesome a/c tech I found in town swapped just the 24V magnet; the new clutch pulley, bearings, etc. remained on the new compressor.
I think if I was looking to replace the clutch I'd go 12V with a 24V/12V relay.

That's what I had but the relay was supplied with 12 volts from my low side battery via center tap...not good. I guess I could have supplied 12v from my 12v auxiliary fuse panel but it introduces a level of electrical complexity I wasn't excited about. I'm trying to mess with the 24v electrics as little as possible. Easy enough to switch out just the magnet but I ordered the whole setup so got new pulley, bearings, etc. as well. Wondering why you didn't just go with 12v with a relay if that's your preference?

Any chance you can post up some pics of how you wired this up?What converter and relay did you use and where did you mount the setup to keep it clean?

Thanks for the info, I don't actually have the vehicle yet, but I know the AC isn't working properly. For now I am just researching so I can run through the trouble shooting when I get it and have an idea of what's involved in the fix.
