eveready Posted December 25, 2016 Share Posted December 25, 2016 1993 Mack ch613 has a 50 ton wrecker body on it. has a 12k lbs front axle, went to have it aligned and was informed it was going to have to be replaced,. My question can I change it to a 18 or 20k axle,.. also would like to have bigger front brakes.

terry Posted December 25, 2016 Share Posted December 25, 2016 I am pretty sure but I believe the DM front axles are the same from center bolt to center bolt, I have been told guys have taken dfront axles from a DM and put under a CH. terry 1 Quote Link to comment https://www.bigmacktrucks.com/topic/48110-can-i-switch-to-a-larger-front-axle/#findComment-356038 Share on other sites More sharing options...
Vladislav Posted December 25, 2016 Share Posted December 25, 2016 I doubt on that DM axle possibility. Axle beam castings look generally the same along R's, RW's, MH's, DM's e t.c. But they might have different location of holes for U-bolts. Depending on the frame width and probably front spring width Mack drilled beams different. At least R-model axle has less of distance between the U-bolt holes (left to right) than RW/MH one. And sure R-model beam (and DM as follow) has 3-1/2 wide front springs so the holes on each side are spiced 3-1/2. RW/MH has 4 inches there and I suppose a CH do the same. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/48110-can-i-switch-to-a-larger-front-axle/#findComment-356087 Share on other sites More sharing options...
gearhead204 Posted December 25, 2016 Share Posted December 25, 2016 most of the larger axles I have seen have dual steering gear, but I want to say their was a 16k axle that was still single gear. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/48110-can-i-switch-to-a-larger-front-axle/#findComment-356090 Share on other sites More sharing options...
TeamsterGrrrl Posted December 25, 2016 Share Posted December 25, 2016 IIRC, heaviest front axle offered on a CH was 14k or so. You could hang on a heavier axle, but the CH frame was never designed for higher weights. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/48110-can-i-switch-to-a-larger-front-axle/#findComment-356099 Share on other sites More sharing options...
