where do you buy replacement compressors for 4430, though I delt with air conditioner specilist out of iowa, but cant find them
 
Old trick from the deep south: Wire in a 1,000w power inverter, cut a hole in your cab and mount a small window A/C. Hey, it really does work! *grin*
 
Do a search for "Automotive AC Compressors". There will be a lot to choose from. Find one that has a customer service number, and will help you find the correct compressor.

There should be some numbers on the old compressor, at least a name brand, if all else fails a picture and some clutch/pulley measurements should get one coming your way.

What kind of failure did it have? If it locked up, shredded metal, or has been sitting open, you will need to do some flushing, oil changing, orifice tube/expansion valve, and a new receiver dryer to protect the new compressor. A good supplier should have everything and walk you through the process.
 
If using r-134a I would switch to a sanden compressor as the delco doesn't work as well with r-134a. Hy-Capacity and AP Air both offer kits that use the original lines on a sanden compressor and new brackets and pressure switches.
 
I used to sell a few when I was with O'Reilly's. Seems we didn't have applications on the farm tractors that was very accurate but they were easy to match up from the pictures. Seems many were the old A6 Harrison/Delco compressors with a dual belt pulley and a chaff shield over the clutch (which the auto apps never had).
 
If he's wanting to stay original I did have reasonably good success with the A6's. That being said, the condenser efficiency was usually the limiting factor I ran into since the 12 units weren't as efficient. Good airflow across the condenser is a must.

If he's gonna use 134 he needs a high pressure cut out are don't let it idle with the ac on.. I stopped by a muffler shop they were working on a 73 chevy C10 they had put a compressor kit on it did not use a A6 compressor it had a compressor like this.

It came with accumulator and new hoses the liquid line had a place for the high pressure switch, switch installed it looked neat. He said the customer brought it from Autozone. I would call ap air inc update it and enjoy my cool air.

I convert all GM HT6 to sanden SD7H15 compressors get them from AP. Life is good no more compressor leaks

:D
 
Ditch the A6. Junk. They were designed for a twelve pound system and last forever under those terms. In a three pounder they are junk. Most systems don't use low or high pressure switches and the condenser is poor at best. The condenser is unavoidable. Put a nipendenso conversion is better than a sanden but a sanden is OK. If you want it to work and stay working put the nip on it. Let's it cycle properly and shuts off in excess pressure situations. All tractors plug condensers daily. It then builds to much head pressure and pushes freon out the pressure relief then it runs low on freon and burns up the compressor. A nip conversion avoids this. Some sandens as well but don't waste money on an a6.
