Bob, just go to "Dumbass.com" you can get all the lates apps... like how to make a sandwich, and how to wipe your ass, and so on.. Hell I got one that shows me how to open jars.. jojo

I thought they had an app for that on thier phones??? ooops

So true Mech... So true.. It baffles me that as a customer I have to be a teacher to get the parts I need... I want a training bonus... jojo

I know exactly what you are saying... I do it almost every day... I go to Oriellys and tell the young'n how to look it up, even when I have the part number... it's a sad time for us.. jojo

yes sir... I have 2 spare sets of 200 series tranny books and an extra set of 300 series books, plus Mack rears and drive shaft books and failure analysus books and so no.. I may sell 1 of each set, as a set... jojo

$75.00 for the real book... easy decision... I just bought 2 more books for what i work on.. less than $30.00 each... easy breezy....

just 1,, but its the right one... I will share pics if I have the correct info... jojo

inspection hole at 6 o'clock....

sorry... MP-8 is on the front.... MP-7 is on the rear.. jojo

no... a '0' on the flywheel, and a TDC mark on the front of the cam... jojo

'FJH' Im about to learn something as well... Ive only built 3 of these MP's and done 6+ cam jobs.. and cup's, cup's cup's... I guess I missed the part about how to adjust the idler gear enough to account for a machined head. I too will sit back and watch.. One thing for sure.... I will not be building any of these in my shop.... I will stick to E-6, E-7, and E-tech's.... I have 2 in my shop now.. plus a 3cyl. John Deere diesel.. Jojo

Leaking fuel anywhere.... is a place for air to get sucked in or let air in to let fuel drain back.... loosing "Prime" just sayin... jojo

Mackey... too funny..... I am always scratching my head lately... I have to bring the slacks and air fittings and air valves and so on with me every time, because they have no clue what im looking for, and these parts were standard issue... Good luck getting what you need... jojo

Well Jessica told me that a wheel end repair including a hub, rotor, pads, misc costs, and labor an be over $2000.00 / wheel end.. Been there fixed that.... While a 3600 drum and a set of 4707 QP shoe's is under $300.00... Jojo

I think its time to knock the mountain down to a mole hill... keep on the regular maintenance, and you should be fine for a long time... and fresh filters each time you question it's operation... jojo

Lots of good info here... also check the condition of the wires and terminals in the round duetch plug on the governor housing.. you did say '97 right?? jojo

May I suggest running these valves the Mack way and not the 'Cat' way.. I never stray from the Mack way and my valves are right and quiet... with respect, Jojo

Thanks Mark. I was trying to help him with this, and wasnt sure if the small bolt had a small set of threads inside to cage the fork, like the older Eatons did for the power divider.. I think the leak is an o-ring and/or cracked piston.. Jojo

very good.. I need to go back to bed.. I couldnt sleep so i came here... now im sleepy again. I will check in later. jojo

Yes sir I understand.. I guess, for me, I would go for it because I have had many of these rears apart, just not one with diff locks in a long time. but the inner workings are pretty standard.. I dont feel like im helping much... sorry.... jojo

The front diff. system may just be a power divider lock. It would be going into the input housing..

ok. I understand.. I guess I threw out a few old ideas I had. Yes Meritor is right.. I know I said eaton, but I looked at the picture again, I know that I do not have a Meritor rear end book.. Here in the last month, I bought 3 Mack books from E-bay.. There is a bunch of guys on here from youre part of the world, who are very smart, maybe one of them is familiar with the Austrailian version.. jojo

When you say it locks up while running.... I'd be surprised if it didn't bend a connecting rod, because it sounds like there is an excessive amount fluid entering a cylinder, ie: fuel, coolant, oil... does it smoke bad when it runs? Is the oil level rising? is the coolant level dropping? My first thought would be a bad injector that is over fueling a cylinder. do you have any active or inactive fault codes? You really need to stop running this engine before major damage occurs. Hopefully it is not hurt too bad now.. do you have a bore scope that you can run into the intake manifold to see if there is a really wet intake port? Is there fluid leaking from the exhaust starting and the manifold, turbo, and any clamps before it gets to the DPF? I'm sorry about all of these questions. More info will be here shortly.... jojo

I would think that the o-ring on the piston is broken, or possibly a cracked piston. So then the piston is not moving which wont engage the detent ball on the end of the switch, as you stated. I would just pull the small cover off and inspect it.. .............. I just looked at the picture again.. maybe pull the detent switch out first and turn the lock 'on'. I bet air comes out of the hole. I am wondering if the bolt next to the piston housing is actually a 'caging bolt'.. used to keep the shift fork from dropping out of place.. I don't remember how these diff lock's look inside, because I havent had one apart in a long time. However, sliding this rear end forward is not that big of a deal, in the case that you had too. I just looked again at the picture... I wonder if behind that small bolt is a counter bore with smaller threads, where you would screw a longer smaller diameter bolt, like an 8mmX1.25 metric bolt and it cages the shift fork.. If I remember correctly, to remove the piston housing, you would use a pipe wrench and unscrew it. Maybe get a close-up pic of the data plate. I think its and Eaton 405, I may have a service manual on this model, of course, I also expect a few guys to help you more directly than I can.. Jojo

President Trump could see into the future and protected us and our economy.. Our current President, also saw into the future. He stopped our pipeline on day one, and now our fuel prices are going to reach and surpass the prices from 2005 and so on, all because of the Issues in Ukraine. He planned to cripple our country, and new that Russia's govt. would try to take Ukraine... I wish I was more eloquent, but I'm not that smart. I just call out what I believe I see. It makes me sick to think the appointed one, was put in place to destroy our great country.. Opening our southern border and giving away everything to these Illegals, that WE all have to pay for out of our PAY CHECKS, something that these people dont have a clue about. Not to mention the intentional destruction of our relationship with each other by allowing the claims that all white men are racist, and all criminals need to be free, and we need to understand why they are criminals. Whats next J.B.?
