25002500 Posted June 6, 2010 Share Posted June 6, 2010 I have a 1996 Mack CH613.I tried to have the air dryer cartridge on the air brakes changed out.The mechanic said there was not cartridge on this system.Is he correct? If not what is the part number for the cartridge? Quote Link to comment https://www.bigmacktrucks.com/topic/14222-air-dryer/ Share on other sites More sharing options...
rhasler Posted June 6, 2010 Share Posted June 6, 2010 There are several different models available in a couple of brands (Bendix and Meritor/Wabco). Without actually looking it up by chassis record theres no way to know what it was built with. The Bendix AD-9 is a popular model, but the cartridge is not a spin on. It is mounted inside of the air dryer assembly. This may be what you have since the mechanic says there is no cartridge. There are rebuild kits available for them as well as exchange units. I'm unsure of the cost of the rebuild kit compared to the exchange unit. By the way, don't go cheap on this. Make sure to buy whatever you get from a reputable source, there are all kinds of counterfit air dryers out there. There have been cases of air dryer cartridges filled with cat liiter instead of dessicant material. You may be able to identify your air dryer yourself by visiting the Bendix website & looking at their quick reference guide. Quote "Mebbe I'm too ugly and stupid to give up!"

rhasler Posted June 6, 2010 Share Posted June 6, 2010 Here's a link to the Bendix Quick Reference Guide. Air dryers are in section 08. http://www.bendix.com/en-us/service/library/Pages/Home.aspxHopefully you can identify it by comparing to the one on your truck.
