I decided to finally tackle the annoying compressor warning I've had for a week or two. I figured the desiccant was in need of replacement so I purchased one of the kits online. I was also planning to have a look at my suspension joints as I have a knock and figured one of the bushings was worn.
What I would like to figure out with the help of folks in here is which compressor this is, I am assuming the Hitachi and I do not believe it has ever been replaced judging by the condition
Sorry about the pictures not being too good.
Can anyone confirm which version this is Hitachi or older or newer AMK
BTW I put this forward as the most corroded compressor ever
Cheers

Also those brackets are often broke, but wow that is a lot of corrosion. New brackets are about $30 in eBay. Also you will want new j-nuts, those are the nuts that clip onto the frame so what you attach has a nut to secure into. If you need the size I can look at the ones I bought. But since you probably need new hardware too, I would just get a three 10mm nuts that go with some j-nuts. Nuts at least an inch long, plenty of room in the frame though.
Also you may want to cut the intake/exhaust lines after the bend and puck up some push-connects. I think one line is 8mm the other 10mm. Neither ever hold pressure. But the exhaust one is almost always "welded" into the port from heat so the fitting fails. And you generally can not unscrew the end fitting on the compressor to get the upper exhaust line out. That seems to be due to a production flaw where the threads get messed up. Two so far I found that issue so there was no way to transfer the end cap fitting.

Thanks Dakata, I figured it would be the Hitachi, but a second opinion is always a good idea. I also pretty much knew new hardware would be required as what is there is totally corroded or to the point of having just disintegrated. I'm pretty sure I have a link to a guy that put a kit together for all the hardware and push fittings etc, but feel free to post what you have by way of info.

Well seems I was incorrect and the link I had is no longer active for the hardware.
I can find a compressor on amazon quite easily - lots to choose from, but don't see much by way of the mounting bracket and its associated bushings or the clips and bots for the frame mounting - if anyone has a link or details of these - especially on Amazon that would be great. I usually avoid anything from US companies such as Atlantic British even though may have the parts as I get hit with crazy shipping and taxes seeing as I am in Canada
Some of those cheap compressors may not last long. Before you jump to replacing it, did you diagnose it enough to know for certain the compressor is at fault? With all that broken hardware it will sound much louder than normal.
Anyway, eBay has the mounting brackets. For the three rubber mounts I was only able to locate a source in Germany, again from eBay, that had an even remotely decent price. I think about $80 for a set. So I just reused my old ones and added the new bushing to my list of wants not needs.
The code I have for the compressor indicates the desiccant needs to be changed and at 10 years its about right for it. Problem is the compressors metallic parts are equally corroded as the bracket and the bottom bolt for the external cover is sheared off. I can see that trying to extract it will just result in the bolt hole disintegrating - its basically being held together by the rust and corrosion. I'm not even sure I would be able to get the cover for the desiccant chamber off looking at the bolts. So really its not a case of the compressor being noisy, just that its in such poor condition I have no idea how much longer its going to hold out.
As for the bushings, one is missing, and the others are very perished, so they need to be replaced. May have found a supplier who has them already installed in the bracket for a reasonable price - just awaiting their confirmation.

I am not aware of any code that would relate to desiccant. As for the torx screws on the dryer, they will comes right out. They are course thread and into plastic not metal, so no issues there.

I'm also not too worried if a replacement only lasts a year as I will be selling the truck once this is taken care of as I am looking to move and can't take the truck.
If you check car-part dot com a used compressor with brackets can be had as low as $150 bucks. The housing on your compressor is pretty rough and I'm surprised it hasn't failed or leaked sooner. Since you will be selling the vehicle, might be a very inexpensive and quick fix which could potentially last some time. Really a straight forward job....I could pull or install mine in 30 minutes. First timer might take an hour out or longer due to the corrosion and maybe an hour install time.
Which EAS Compressor is this
