Ladybug1969 Posted December 8, 2022 Share Posted December 8, 2022 Is there a trick to mating these two back together? Which seems easier: inner cam inside peanut/wedges or on the shaft inside the outer cam? This is kicking my butt. 02 ch613 4.17 rear TIA CHRIS Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/ Share on other sites More sharing options...
Ladybug1969 Posted December 8, 2022 Author Share Posted December 8, 2022 Close as I've been able to get it. Can't seem to finesse the second row of peanuts into the inner cam Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/#findComment-517740 Share on other sites More sharing options...
theakerstwo Posted December 8, 2022 Share Posted December 8, 2022 The cam is different on a air locker than a auto locker.Check that out.

Joey Mack Posted December 8, 2022 Share Posted December 8, 2022 Lightly grease the peanuts, inside and out... Push all the peanuts from the inside to the out position,. The as you SLOWLY insert the inner cam , rotate the yoke slowly and it will go right on.. I believe the inner cam is in backwards. The oil grooves go to the cam drum nut..

Mark T Posted December 8, 2022 Share Posted December 8, 2022 What Jojo said....or ??? take the through shaft out from the back !!! PAY ATTENTION TO THE CLOCKING OF THE OIL TROUGH !!! then put the inner cam in the power divider unit. Bolt it to the carrier ( don't forget air shift goes about 7 o'clock looking at it ) then put through shaft back in. Might be easier if you're not familiar with them. That power divider is a little heavy to finesse in there without some frustration. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/#findComment-517748 Share on other sites More sharing options...
Ladybug1969 Posted December 8, 2022 Author Share Posted December 8, 2022 Oil grooves on the inner cam are against the outer cam/drum nut(facing the rear end per my dude here). So, leave the inner cam on the through shaft, grease the peanuts so they don't fall back in when rotating. I'll just have to move them slightly to get past that leading splined edge of the outer cam/drum. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/#findComment-517749 Share on other sites More sharing options...
Popular Post fjh Posted December 8, 2022 Popular Post Share Posted December 8, 2022 I'm not maybe reading this right how ever ! I load the cam in the peanut cage and fumble that whole lump peanuts and all into place the slots on the inner cam face towards the rear to let the oil from the main case flow up the shaft to the pd ,rocking the yoke back and forth till it slides in leave aprox 3/4 of an inch out to put silicone around before buttoning it up! 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/#findComment-517763 Share on other sites More sharing options...
Joey Mack Posted December 10, 2022 Share Posted December 10, 2022 How did it go ??? Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/#findComment-517838 Share on other sites More sharing options...
Ladybug1969 Posted December 16, 2022 Author Share Posted December 16, 2022 Finally got it in the next evening. And yes, it was a royal pain in the butt. Pretty much a hunt and feel operation. We did it with the inner cam inside the peanut shaft as mentioned above. Not a job I ever wanna repeat. I do have another question. When we pulled the outer cage, there were 2 spacers behind it. One 5/16 inch thick and the other I would guess to be 3/8 -ish. What's the purpose of these because neither show on either a Mack or PAI diagram(got Mack dealer to print me one)?. We found the smaller spacer by the part number stamped on it(is described as a cam cage spacer) but neither are shown or listed when you pull up the diagram. The only spacers found were between yokes and seals(coincidentally same size as the small one with different part number) part 62 in this Mack graphic Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/#findComment-518380 Share on other sites More sharing options...
Joey Mack Posted December 16, 2022 Share Posted December 16, 2022 Those are measured shims. the number on the side is the part group + the shim thickness in thousanth's of an inch.. Extremely important for proper bearing pre-load.. Which for re-used bearings is 2-5 lbft, and for new bearings, it is 3-6 lbft.. Did you replace the outer cam drum? jojo Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/#findComment-518381 Share on other sites More sharing options...
Ladybug1969 Posted December 16, 2022 Author Share Posted December 16, 2022 Jojo, everything in it got replaced except the shaft the peanuts go in. Those with the retaining rings got changed, and the bearings. A mack mechanic rebuilt that section for me. When it was disassembled, those 2 spacers were behind the outer cage/drum, and a 3rd(5/16th thickness) was inside against inner cam. Part number was 77KH219. I can google that part all day but I cannot find it in any diagram, nor do I see those 2 we found behind the cage. I don't know the part number on the larger spacer Quote Link to comment https://www.bigmacktrucks.com/topic/70843-power-divider-with-air-locker-install/#findComment-518388 Share on other sites More sharing options...

phildirt Posted December 16, 2022 Share Posted December 16, 2022 Would you mind saying what the parts cost for this project was? If you don't want to post it - just send me a private message.
