FS6 compressor rebuild help?

[chillman88]

Anyone here done it? I'm trying to figure out if I should keep going or not after seeing the dirt in the inlet/outlet.

I'm also wondering what this is for. To let out oil that bleeds by the seal but keep dirt out?

So I was worrying about the dirt because I had read something in this compressor was VERY difficult to get back together. Finally found my source:

Looks like I should be able to flush everything out once I get the front cover off. I'll give it a go in a couple days and see what I find.

All you can do is continue. The whole system is going to need a flush. it's very hard to get a contaminated system clean.

That's why I'm replacing EVERYTHING except the compressor. I'd replace the compressor too if it wasn't so darn expensive. Too many things to do to dish out another $200 for a compressor. Reseal kit was $15 so I couldn't not try.

let us know how it works, i found another "looks good" used one and put that in. i was always curious about rebuilding one though.

Replacing everything is the way to go. Like you said it gets really expensive. If I have a repair like that here in the shop I won't warranty it unless we do the whole system.

If I get it together and it actually works I'll probably do a tech writeup on it. I've noticed there's not much out there on them.

Sweet, well if it doesn’t work out I’ve got a bunch of used/unknown condition compressors that have come off core engines. You’re welcome to take as many as you like, they’re scrap otherwise.

I was going to ask you anyway if it didn't work out lol. I figured you'd have a spare or two!

They make excellent onboard air pumps if you have a dual pulley power steering pump. Something I've been working on with my old nippondenso ac compressor from my 6.9 that I had no use for when I put my under dash ac system in and it required the other compressor that came with it. I have all the hose and fittings a guy could ask from my grandpa's old shop and a tank, just need to get an oiler for the compressor and a pressure switch that works and it will be done.

That's definitely a project I'm considering. I do have a dual belt pulley on my steering pump.

 

[BrianX128]

The only problem then is mounting it. I had a pto lever I was using from a mower and I just made a metal plate to sit the compressor on and this was bolted inside to the fender. If you wanted to turn the compressor on (or leave it on if I had a pressure switch) just engage the pto lever and it pushed the compressor harder away from the power steering pulley to tighten the belt. But this is all a stupid idea now because the engine moves enough separate from the fender area that the belt just leaves at random.

I'm sure a better fabricator than I could find a crafty way to mount the second compressor off of the existing bracket. It might just come to giving up on said project because I'm for sure not giving up the AC lol..

 

[chillman88]

@BrianX128 why were you messing with a lever at all? Did the compressor you have not use a clutch? I wouldn't think it so odd but I've never seen one without.

With an electric clutch and a mount its stupid easy to control the compressor with a switch. Manually off or automatic based on a 12v pressure switch in the tank (yes, I've spent a lot of time thinking about it).

The only reason I HAVEN'T done it yet is the issue of oiling the compressor without oiling the air tank. Yes you can set up a filter system but there is the issue of water emulsion and recirculating the oil.

I've been tempted to try getting a Teflon oil ring made up for the York compressor I have sitting in the garage but never got around to it.

 

[BrianX128]

I didn't have a pressure switch to shut the compressor off at all, so I just used this plate that was my best piece of scrap metal and then realized it was used to move a pulley under a mower back and forth so I thought this might help the belt tension problem more than the wiring/ clutch part.

If I ever have the time to actually attempt this the right way, I just want to put "arms" off of the mounting holes for the regular ac compressor to hold this compressor and use a turnbuckle or something to hold the tension of the belt.

A factory built mount to run two A/C compressors was once available. It was for small reefers mounted on F350 and FSuperDuty Chassis. It was like an aftermarket PTO part. I had a picture of the set up. The York or Tecumseh for the ****** (or the air compressor in this discussion) went where the factory compressor was, then the original AC compressor sat on top of it. If I were doing all that I would switch the AC compressor to a very common and cheaper Sanden.
