Tim Modine Posted July 16, 2020 Share Posted July 16, 2020 Evening Truckers, Hope all is safe from this crazy virus. My question is that I've got an 07' Mack CHN613 that i recently lost a cab air bag and the leveling gauge blew completely apart and lost all the pieces to it. So I was wondering if somebody can give me an idea where to measure from to get the leveling gauge to inflate the cab air bags to the right height since i lost the rod from the original leveling gauge the was in there. I took a guess but with the tractor and low boy and a 27tn excavator loaded its so bouncy that the cab will literally bottom out on the rebound going up after the cab compresses to absorb a bump. Un loaded it rides fine, but loaded is another story. Could those little cab shocks that i don't think have ever been changed with probably 659k miles on them part of the problem. Thanks in advance, Tim Quote Link to comment https://www.bigmacktrucks.com/topic/63339-air-ride-cab-leveling-height-measurement-location/ Share on other sites More sharing options...
