mackone Posted February 10, 2021 Share Posted February 10, 2021 Hi, I'm needing a air compressor for my 1989 Mack, it has a E-6 350 Econodyne engine, local place I deal with that sells truck parts said they would need the number off the compressor to get the right one, but the numbers are wore off the tag can't read nothing on it. Was wondering if anyone would know what the model number is , or which compressor I would need? Quote Link to comment Share on other sites More sharing options...
Rob Posted February 10, 2021 Share Posted February 10, 2021 Could be a Bendix. or Midland. Can you post a photo? 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke. Link to comment Share on other sites More sharing options...

mackone Posted February 12, 2021 Author Share Posted February 12, 2021 I added some pictures, don't know if they are good enough to tell anything I haven't taken it off yet, was trying to get one located first, but may have to go ahead remove it.

doubleclutchinweasel Posted February 12, 2021 Share Posted February 12, 2021 Could that be an actual Mack compressor??? Quote "Eagles may soar, but weasels don't get sucked into jet engines." Link to comment Share on other sites More sharing options...
mackone Posted February 12, 2021 Author Share Posted February 12, 2021 Yes Doubleclutchinweasel it looks like the one you posted, so Is that is the one I probably need? Quote Link to comment Share on other sites More sharing options...
Rob Posted February 13, 2021 Share Posted February 13, 2021 Yes, Midland. Easy to replace and I feel better than the Bendix 501 series as the unloaders for the valves can be serviced without removing the head.

mackone Posted February 13, 2021 Author Share Posted February 13, 2021 O.K. Thanks for everyone's help with this, How do I know which series Midland compressor I need (EL1300, EL1600) , or will either one work? Again Thanks for all the help.

Rob Posted February 13, 2021 Share Posted February 13, 2021 EL1300 is most common in those years but they will interchange. The EL1600 is a higher displacement but the same physical size IIRC. Change your drive coupling too although the original may look perfect. Power steering type which you look to have: Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

It'll make you feel silly if you do! 1 Quote "Eagles may soar, but weasels don't get sucked into jet engines." Link to comment Share on other sites More sharing options...
mackone Posted March 9, 2021 Author Share Posted March 9, 2021 Oh yeah I made sure that the tube was in there. Its probably not good on the air compressor without it I'm guessing? Quote Link to comment Share on other sites More sharing options...

Fastduramax Posted March 18, 2021 Share Posted March 18, 2021 Hey Mackone let me know what you got new or reman and from who and most importantly if it pushes oil through your system, I'm on my third compressor right from Mack and it pushes oil like a Saudi oil field ugh !!! I gave up, I just chase down each valve and maxi can the oil ruins... Ironically just today replaced my heater/AC control panel and both piston accuators the oil has ruined !

mackone Posted March 20, 2021 Author Share Posted March 20, 2021 Fastduramax, I got a remanufactured one from a place called Rebuilders Enterprise in Bridgeview, IL. So far all noticed is a little bit of oil residue out of the air dryer not much just small amount. I'm hoping it is from oil that was already in the system. Before I changed it, pushed oil out bad, big puddle out the dryer, and In all the lines. Nice RD you got there btw. Quote Link to comment Share on other sites More sharing options...
Rob Posted March 20, 2021 Share Posted March 20, 2021 REI is a very consistent rebuilder and I've used them several times. Nice folks too if you visit them. EPDM rubber does not fare well when in contact with engine oil and readily swells, softens, and/or splits. It is the rubber the diaphragms, and piston cups are molded from in the aforementioned failing parts. With a failed air compressor one is best to remove and flush the discharge line from the air compressor to the air dryer or wet tank, and the wet tank at least as this is where most of the "tramp oil" will accumulate. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
