03' Big Red Posted September 9, 2022 Share Posted September 9, 2022 Can the CRD112/113 be made to be full locking? often the power divider isn’t enough Quote Link to comment https://www.bigmacktrucks.com/topic/70415-full-locking-rears-needed/ Share on other sites More sharing options...
R.E.D Posted September 10, 2022 Share Posted September 10, 2022 I'm not sure that mack rear ends had "full lockers".they did have interwheel locking differentials which I believe uses cams just like the interaxle power divider.But I think they are pretty rare and parts would be hard to source.. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70415-full-locking-rears-needed/#findComment-508954 Share on other sites More sharing options...

mrsmackpaul Posted September 10, 2022 Share Posted September 10, 2022 My brother has in recent times finally after many many decades had a life changing event happen, he has bought a Mack, think it is 1984 build His is a ex army (Australian Army) 6x6 and it has 44 rears and has full cross locks on all three axles from new as well as inter axle powerdivider lock and transfer case lock It is standard from Mack Australia full time 6x6 fully locking 6x6 So I'm guessing that if we had it in Australia then they are definitely available else were as we really got the scrapings from the bottom of the barrel compared to the states Paul 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70415-full-locking-rears-needed/#findComment-508965 Share on other sites More sharing options...

DieselDog5.9 Posted September 11, 2022 Share Posted September 11, 2022 On 9/9/2022 at 9:02 PM, R.E.D said: I have seen this setup in single axle plow trucks, the little peanuts come out and lock against the outer plate, but I did not think it was selectable, thought it acted as a locker/posi works in a car differential. Any Mack I have seen with "quad locks" has hendrickson suspension and Rockwell or Eaton rears.

Quickfarms Posted September 12, 2022 Share Posted September 12, 2022 Back in the 80’s I drove a 1975 DM600 roll off truck that started out as a power company truck. There were two air levers on the top of the dash, one was for the power divider lock and the other was differential lock. In the mud I would flip both levers and it would claw its ways through the mud turning all eight rear tires currently i have an ex US Navy truck that has Detroit lockers in each rear axle and the air lockable power divider. I also have a two axle truck with an air lockable rear axle. It is actually common for the tractors that were ordered to haul bottom dumps her in California Quote Link to comment https://www.bigmacktrucks.com/topic/70415-full-locking-rears-needed/#findComment-509192 Share on other sites More sharing options...
Mark T Posted September 12, 2022 Share Posted September 12, 2022 I think newer Mack carriers have an option for lockers similar to Meritors or Eatons. I know I saw a tractor with an air line going into the carrier on a new truck a couple years back. They had some other number too , wasn't 92/93 Quote Link to comment https://www.bigmacktrucks.com/topic/70415-full-locking-rears-needed/#findComment-509210 Share on other sites More sharing options...
