I have to change compressor that's attached to engine. It's a Detroit Diesel Allison 501 compressor 28599 .. but can not find the right compressor I need the compressor and air dryer .. but no luck finding it talked to Newell and they are saying 3 month wait... SMH frustrating ? anyone know a good place to find the compressor it's older model compressor and system.. ? Thank you.. and I think I found it .. it looked different than the ones I was pulling up for reference ..

I mean I think i found location of air dryer.. then was saying I'm looking for correct part to order.. I noticed the way I worded it before could be confusing.. just wanted to explain ?

The air dryer has a desiccant cartridge that can be changed, Unless there is a crack or some other internal failure, the entire unit should not need to be replaced. The cartridge replacement is roughly 30-35 bucks.

 As far as the compressor itself they do fail. Do you have a Detroit series 60? Is it an 8V92? Ill need more info to point you in the right direction on that. The part number you supplied i believe is supposed to be 285995. that would make your engine an 8V92. The compressor is really a simple device and is rebuildable. It consists of a piston with compression ring a intake and exhaust valve and a head gasket. All on a gear drive from the engine. try this link and see what they have,  https://www.ebay.com/itm/112943546550

For the time being what is wrong with your compressor? Are you sure its the compressor that has failed? Can it be rebuilt locally?

Are you losing air? Not building enough air? Have you changed the governor?

Any response from me may be delayed as I'm in Alaska.
