Thanks Dave,,,,, Wil do.... jojo

$166.00/hr. here in Salisbury N.C. at the itty bitty MACK dealer here..

sir,, with respect, I have to bow-out.. seems to me you have a home made truck, and the only way to get parts is like I said, with the component serial numbers.. and I am sure you will always have to remove the bad parts and take them with you, to the parts store.. I pray that you have NON-Mack parts store's that know what they are doing.. I suggest you record all of the data of of any data plate you find, ie: tranny/ engine/ rears/ axle housing's/ front axle beam/ steering box/ the v.i.n. on the frame rail/ the v.i.n. on the cab shell/ etc... this effort will help you later on.. God Bless you sir.. Jojo

if you have a good Mack parts guy, he can tell you what it was built with... when major components are replaced, like the engine, tranny, and rears for example,, you need to use the serial number of the part and not the v.i.n.,,, just sayin'...jojo

Wrong maxi's.. those are for drum brakes...

the last pic, with brakes 'on' is the measurement you need to duplicate..it looks like pre-made brake chambers, with welded yokes.. he is right about not going passed 90 degree's.. my guess is the new maxis you have dont have threads all the way down to the service side housing??

it's smoke and mirrors, for 2024... there will be more to come.. Guns are currently the next one, white skin will continue to be an issue, and the words Boy and Girl will be an issue, and of course,,,, funding!!.. funding!!.. funding!!.. I also expect a shortage of rainbow patterned cloth, as well.. shoot, dont forget a new "Variant" pick one... Luv u, jojo

MACKS, you must have heard me... 'Cause when it popped, thats exactly what I said... jojo

honestly, it is now easier for me,, I can just take my torch and cut it apart, and start fresh.. I will have to cut the yoke of, unless I can get a main shaft and yoke for a good price.. .. Heck I never have bought a complete back box before.. can that be done? I have always just re-built them..

Well here's first time for me... I have done dozens of these and at times had to use a sledge hammer and a helper to remove the yoke.. But, never has this happened.. I had it in my Harbor Freight 20ton press, with pressure on it and i was heating the yoke with my torch.. and when the tone ring was able to spin I gave it 2 more pump's, and WHAM!!! I cant wait to tell my customer... jojo

replacing all the brake chambers is a good idea, maybe as you do it, perform the test that Glenn suggested, so that if you find the issue, you get the answer to the mystery, and the brakes have all new cans of equal quality.. good luck, Jojo

I am at a bit of a loss.. i dont know how , truck off or on has an effect, unless there is an electric over air switch.. Im sorry, it is also 9:30 PM here and I need to hit the sack.. I will check back tomorrow... jojo

oh hell, the small one is likely a pressure protection valve, and the other one should be the anti compounding valve. My guess is you have a bad maxi, if the plumbing is correct..

the second valve should be the service valve... the one that applies the brakes when you step on the pedal.. the first pic is the park brake valve... Did you do what Glenn asked, and remove a service line from each brake chamber until the leak stopped? you may have a backfeed through the maxi..

ok,,, disc brakes.. I guess thats why, no room for big chambers.. I didnt know the year/model of the truck... jojo

just curious,,,, why such small maxi's? why not 30/30's?

the brake valve is bad... it gets constant air pressure to it as long as there is air to be delivered.. the spring brakes dont have air pressure in the chamber until you push the brake release valve in... on the brake valve in the frame, there should be an air supply line, and a signal line ( brake release valve line) and 2 or 4 lines off the bottom to the rear chambers on the maxicans.. more pictures are always a good thing,.. jojo

So Roe-v-Wade, is overturned.. Ok.. well... the only people that are pissed off are those that want to make money off of abortion's, and those that use it as birth control.. There will always be a 'real' reason for an abortion, IE: saving the mothers life, especially if she already has a family of children, and need 's to be here taking care of them.. I really dont have a lot to say on this. However, I did see where they incorporated, 'Gay right's' and Racism, into this issue... well at leaste here in Charlotte, N.C. and of course all of this is being staged to try to destroy the republican vote this year and in 2024. ok, time for me to take a break... jojo

I found a used one on E-Bay.. $1,000,000.00

Christ Almighty!!! Glenn, That is B.S. But I believe you.. At my shop, I currently have a synchro job in a Metric Eaton... FRO16210C.. I have done dozens of these.. I told My customer that I am on the road building 3 E-7's. and dont know when I can get to it.. They dont want to take it to a shop.. I guess I need to step it up.. so I guess tomorrow, I pull the back box.. When i was at the last dealership.... no-one their knew how to do a synchro replacement in an Eaton, with the tranny in the truck... I actually had a boss man say,, 'you cant do that' I said,, "are you F'n kiding me?" ,, anyway 2 days in the shop, and it was, out on the road, hauling grain.. I still cant rap my head around, how few repair shop's there are.. jojo

oh hell thats too funny,, I saw your birthday and forgot to say...... Happy Birthday.. sorry bud,, jojo

Yep, My magic wand is on 'back order'.. No E.T.A. or notes on it... jojo

Well, no info on what caused the fuel in the oil. I inspected the cam while I was in there and the #1 exh. lobe has a chip in the lift.. So I am definately re-building this one too.. Be careful what you wish for.... I needed some work a couple weeks ago, and now I have 1 customer with 3 engines that need re-building.... An ASET-C, which I loaded pistons and liners into yesterday, waiting on the lifters.. An E-tech, and an E-7 V-Mac II.. I still have one of his ENDT 673's in my shop, and another 3 cyl. John Deere to build.. 🙄 Sorry I dont have an answer as to how the fuel got into the crankcase.. If I do find the reason, I will post it.. thanks guys, jojo

Sad but True, Mech.... I could never go back to a dealership.. Hell,, they dont want my kind anyway, Jojo

Ricky.. Do you have a red and yellow park brake buttons? if yu only have the yellow, you need a tractor protection valve for the truck. and maybe a new anti compounding valve in conjunction with the R-12 valves, in the frame.. There are a few way's to do it.. ... just curious... jojo
