So now that setup is for nearly 100 years in the industry. With about no changes to its design. And been used in such reputable trucks as R, F, B-models... Does all this sound it's a weak spot? Sorry Mark, this comment is more adressed to Jojo. 1 Quote Никогда не бывает слишком много грузовиков! leversole 11.2012 Link to comment https://www.bigmacktrucks.com/topic/74671-mack-rear-end-popping/page/2/#findComment-560897 Share on other sites More sharing options...
Vladislav Posted October 27 Share Posted October 27 And speaking the particular truck. The inner cam looks in good shape in relation to the outer one. So possibly was swapped not long ago. The peanuts are a questionable mater in the case indeed. I will keep my eye on this thread too, would like to learn the turn out.

Joey Mack Posted October 27 Share Posted October 27 The auto power divider still allows the wheel with the least traction to spin. for example on uneven terrain whe the wheels are dramatical at different levels to the ground.. and I also believe they dont like severly un-even tire wear.. like when you put new tires on one axle but the other axle has nearly worn out tires..

To me the power divider is a sample of absolute engeneering genius. I just can't imagine how a man could desing this kinematic device. And it offers unique functional properties. Being said not being "an automatic lock out divider" but a kind of a differential. I suppose you read the this text in the past. If not it seems very remarkable. Sorry for the quality.

Mark T Posted October 27 Share Posted October 27 I'm with Vlad on this one. The cam and wedge system of the Mack along with overall design of the double reduction rears.... then throw in walking spring suspension, all adds up to a truck that had the ability to walk through all kinds of terrain. Personally, I never understood why they even added air lockout to the Mack power divider. Even with air lock, it's still doing it's thing. Unless it's worn out.

Popular Post terry Posted October 27 Popular Post Share Posted October 27 I have to say if there is a weak point in the mack power divider, the early ones would break a through shaft every once in a while And yes i do prefer the air lockout divider, especially when the internals are worn. Terry and yes i have driven both, with and without the air lockout. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/74671-mack-rear-end-popping/page/2/#findComment-560916 Share on other sites More sharing options...
