kingpins are around 350 depending on were you get them torque rod you replace the whole rod not just the bushings the rod around 150

that should be your brake valve e6 I believe if its leaking out the the rubber flat on the back could be a brake chamber back feeding through or relay valve or the valve it self take some needle nose vise grips and pinch off each supply hose to each brake chamber tell you find it dont use the same vise grips buy four of them if you dont have them already sometimes you have more then one chamber feeding back if the air does not stop remove your signal line to your relay valve and see if there is air coming out of valve through signal port the signal line is from e6 brake valve (the one that is leaking) to the relay valve should be on top of valve if there is no air then I would suspect your brake valve is bad

maybe a piece of junk got hung up in the low air pressure switch thats what turns the light off are all the tanks 120 psi both primary and secondary might not have air getting to them throught the wet tank bad check valve

do you mean the brake valve........ what kind of trk....... pics...... could be brake chamber bleading through innner seals in maxi's

only two ports not a check valve does not hold air in ether direction but seems to limit the air a little when air is put in the direction it was installed does have an arrow took valve apart has big long spring metal disk and in the bottom there is another chamber with a metal ball this valve is in the line from the bake valve to the relay valve for rear brakes this trk does not have front brakes

does anyone know what this valve is and what it does

love macks sadly I had to sell mine 3 years ago to move the family but always looking for another b model right now I have a 1957 peterbilt 281 234 wb nto cummins spicer 8251 5 spd main spicer 4 spd aux rockwell double reduction rear end 5.91 ratio looking at another 281 a 56 but is in sad shape would love another mack though

RIP ben bruckners was a good place for parts and service even it was not a mack I delt with bruckners in farmington nm it is a shame he has passed

I do know there is a lot of axle twist when empty with this suspension but I do like the disign has more axle loading on uneven ground comes in handy with only one drive and a tag

well I have a nhb cummins non turbo that was turned into a nto 262 by putting on a t50 turbo and a 262 pump from what I heard cummins did this all the time did they change serial numbers on the engine when they converted them my engine serial number does not match my build sheet engine number the build sheet says nto on it and the date code on the engine says 1957 which is what year the truck is

how hard is it finding parts for the page and page suspension also anyone know 743 cummins motors like the back of there hand
