Joey Mack

the tool i have is an OTC tool. it works very well.

Kent Moore is likly the brand name of the tool you used

i have an old nut that I cut flutes into to mak it a chaser...

https://photos.app.goo.gl/cEWs2STA8AoMiWpG7 JoeH.. here is my king pin nut socket,,,, 1/2/drive...

Amen JoeH,,, the top cap may also be pinned in, and the welch plug types can be punctured with a sharp punch and twisted out,, you may squirt a bit of grease on you , but so what... I hesitate at times to say how many times I have done a repair, because I dont want to sound like a know it all, in this case,,, not a know it all, but a know quite a bit.. guy. dozens of king pin sets in Mack axles...

it just takes some work and attention so as to not damage the top of the knuckle as you drive out the old pin, once it moves a small amout it wil drift or drop out.. its tapered and it only needs to move laess than an inch, assuming your steering knucles arent siezed..

rubber duck,,, wheres the C-10?? all i see is the C-20 camper special

what year is the 'R'? I never used a tool like that, only ever set the axle beam on stands, pulled the wheels, and some times the backing plates, and knocked them out with a sledge hammer and a home made steel handle with an old king pin welded to one end of it. it take s 2 guys.. the bushings can be pushed out with the metal cutting bit on a good air hammer if they are the thicker brass bushings, if the bushings have a seam in them then you can drive a sharp beater screw driver in where the seam is and they will fall out. of course you may have to buff out the bore due to deep scratches.. not need to be abusive, just diligent.. theres more but I want to see your response.

the C-20 is the one I want.. I need to add more square bodies to my collection. only have 3

Heck if it is well maintained and not beat up from plowing, it seems fair..

can you post pictures of the info stamped into the main case near the fill plug. is this a T 107 twin stick. ?

is that engine set up for a cab over?

TJC.. ???? what???

good deal,, thats a Mack Mack not a Volvo Mack...

I doubt ECM.. I would look for damaged wires on the frame and not sure about wires on the diff. Memory escapes me right now..

It should be VJ1-3-0.8. So that is vehicle ECU plug J-1/ pin 3/. Wire size ( not relevant) .8.... The code stays the same on the whole circuit, this can be used to trace wires and use a DVOM to check continuity and such. This way you dont have to pull all the wires out, just look for that code.. i gave you this info in case you have to go deeper than the basic checks.. jojo

Ok. If this Mack has the Volvo frame, then there should be a bank if electric over air celenoids on the cross member behind the cab, possibly on the frame. There is where the air is sent to the lockers,

Ok. The wire code is printed on the wire. It tells you where the wire goes its size and pin number in the ECU plug. Can you post the numbers on each wire?

I read this again. New oil pump, 2001 with the large nuts on the end of the rocker shafts ?? Seems odd, but ok. Hand held gauge shows the same low pressures,, how many hours on the engine? Have you rolled a set of rod and main bearings recently? I have seen that boost pressure 15 PSI. Sounds like you have a good knowledge of this engine.. Jojo

Your good. I just toss some humor in the mix.. you are brilliant..

it's a possibility.. however, this oil pump in my opinion is excellent. and no other failures or issues were stated.. Of course I am diagnosing from my couch, but this engine has been known to push the welch plugs out of the rocker shafts, and you will see oil pressure, but of course not enough to lube the engine properly.. I would like to know what repairs were done recently.. For some reason my 'knee jerk reaction' is the welch plugs.. I am familiar with being wrong,,, I'm Married

I have seen the welch plugs in the end of the rocker shafts move, or just pop out. The condition you have is similar to that issue.. pull the valve covers and take a peak..

Still off track here Bob, Now lets get back to deliscious truck stop food.. 🤣

I'd walk a mile for a camel? I know the phrase.. of course if i smoked a camel cig. I wouldnt be able to walk another mile to get another one, just sayin

50-60 miles on a snow packed road, just to go get some clam strips and fries??? Now thats dedication.. How'd I do Bob??
