Has anyone put on an aftermarket AC compressor on their LS tractor?

[brs78660]

I have an XR 4140 HC and the AC compressor locked up. I was told they use a pretty generic AC compressor, so I don't want to pay the dealer $600 for one and wait on it forever.

Has anyone done this? I would really rather use non-LS parts to fix it.

I have so many issues with this tractor I just have to laugh it off.

Take the compressor to a NAPA store and see if they can match up the mounting and shaft with one of their stock units. With their military or fleet discount you are looking at <$300. If it is a common brand used in the auto industry it should not be a problem NAPA has been my go to place for 50+ years.

It a good chance you have metal contamination all through the system if so you will also need the dryer expansion valve along with the compressor and cleaner to clean the system.

Thank you all. I will try these options. Here is a pic of the compressor in case someone knows it right off.

Thanks RickB. I contacted them and they asked me to send them pics so they can try and find a match. They did seem very helpful. I now have a go-to site for AC repairs. :drink:

I've got 910 hrs on the clock on my XR3037HC.
I have spent $2000 on my A/C and, tomorrow, I'm taking the doors off.
Without A/C in a cab tractor in Florida you have a sauna.
I can't afford the loss I would take to sell and repurchase another unit of equal size.
Besides, the tractor runs splendidly.
I just love it. It's just the right size to get under eave troughs/guts & most tree limbs..
It sips fuel and works like a demon.
Is it perfect? Few machines are.
So I'll just keep it and have a very expensive open station tractor & bimini top with a radio.

BTW: I've got an extra a/c compressor if anyone is interested.
There's a leak in a brand new evap unit on the roof evidently.

Sorry to hear of the issues you have. If my tractor worked right I think I would love it too, but its been nothing but issues and nightmares.

The compressor you have, is it from LS or did you find aftermarket parts? I found that the LS compressor is a KDAC and apparently is only available in Korea or something like that.

AC guys say they are not very good and its better to get an aftermarket one, but I can not find an exact match in an aftermarket one. How much do you want for yours?

I am planning on trying to sell or trade my LS for something else, but if for some reason I can't I may take the doors off too. I am in Texas so I totally understand the sauna.

Trade-in for these tractors is so very low.

List the doors for sale when you take them off. I have heard of people needing them because the glass breaks.

That compressor probably has a brand name and model number on it you can use to search for a replacement.

I just eyeballed the ports, pulley type, and mount on my NH backhoe and bought a generic Sanyo compressor to put on it. My compressor was missing from the tractor when I bought it. I pulled the expansion valve and drier off so I could blow the system out completely with nitrogen then put it all back together. Ended up having to replace every hose also because they were seeping out the walls. Getting the expansion valve off was a PITA and doing it twice was NOT fun.

I think I got the compressor off eBay for less than $200.

Yeah, the compressor is a KDAC compressor and they can't cross reference it to anything really, but I was told its very close to this one: AP Air Inc - New V5 Daewoo Single Groove Compressor

Its about $300 for that one, but the compressor already has a bracket made for it so that it can bolt on the engine. I am thinking about taking that bracket off and making one to fit like a universal sanden 508 or something. You can get a 508 for like $99.

That way its cheaper to replace later if it fails again for whoever owns it. I don't plan on keeping this tractor, its been a nightmare.
