 Topic: Electric A/C compressor
Posted: 15 Jul 2025 at 10:56pm |
John Deere 4050, [6359t (French) engine], a/c compressor is located on top of the engine between exhaust and the radiator. No way to relocate it to another area. Believe me.....if it was possible it would have been moved years ago. The compressors only last 2 or three years. Spoke with others with the same problem. Alternatives are converting from a Denso to a Sanden compressor. This requires a mounting bracket adapter kit.
Another idea it to convert to an electric a/c compressor. Hybrid cars and cars with stop/run engines have electric compressors. Curious to know if anyone has put an electric a/c compressor on a tractor.

You'd probably need a 100+ amp alternator for that mode. Besides, to go from
-mechanical belt to ac compressor is more efficient
than
-mechanical belt to alternator to electricity to ac compressor.

Most of the "KITS" are 24v and pull something like 90- 100 amps...... 24 x 100 is 2400 WATTS or about 3 HP....

Sounds like a 200 amp 24 Volt alternator should suffice

If you run that high of capacity alternator at capacity, best force feed it air somehow or it most likely won't last long. A ducted fan forcing air at/through the alternator would probable work, but you'll have to deal with space constraints and packaging.

I just put in an order for a Sanden A/C Compressor Conversion Kit (AMX10167), $540, from Abilene Machine. Planning to flush the system. Install compressor , receiver/ dryer $28, expansion valve $20 and synthetic Ester Oil $14.

I'm not sure of why so many failures?? Is it possible that you need to fabricate a simple tin heat shield to reduce exhaust system heat onto the A/C compressor ?? That surely wouldn't be too difficult or costly. This heat shield could also maybe help direct radiator fan blast air towards the A/C compressor to help cool it off some. I dunno. I'm not there looking at it.

whatever you do, adding a heat shield is a GREAT mustdo !!
not just a single slab of tin, but 2 separated by a 1/2" air gap, 3 if you've got room. adding a duct or dedicated cooling fan will also be a BIG help !!

There are a few heat deflectors in place. This configuration was NOT one of John Deere's better ideas. I know several people who have the same problem with the same model.

A duct is a great idea. Ducts work great on aircraft engines to direct cool air onto various engine accessories. I think I know where I can lay my hands on some SCAT tubing.

I have no idea what vintage/age this particular tractor is. Does it happen to have what I call an R-4 type Delco A/C compressor like from the mid/late 1980's ?? cause they were junk.

i would modify the side panel or cut and louver the hood if needed to get a fresh air duct from outside to the back or top of the compressor... Let the radiator fan pull the cooler air thru instead of over the hot engine.... assuming you have a pusher fan.

The fan pull the air through the radiator.
