BUD ! HOW ARE SETTING THESE ?????? they don't set like a Cat or other engines out there!!!!!! You need to set on the Valve set marks NOT TDC ! Not overlap , over lap is close but not perfect . the slack on certain valves is NORMAL if not on the valve set marks! the jake brakes are set on the valve set mark of each cyl Usually 15 to 22 thou! separately while setting the valves 16 in / exhast 24-26 NOT 02- 28 you now may have bent a Valve! Read the A BOOK! Your going to ruin something!!!!!! If you haven't already! firing order 153624 1-6 5-2 3-4 Are sister s these are all on the same stroke as each other but doing a diffrent job!

Please do!

Good job! 😎

Mike did you get anywhere with this issue?

Check and clean your battery/starter connections Bad grounds do weird things ! Check the cheap and easy stuff first!

K then if the relays got big wires running in and out those are what you need to focus on! power relay #2 look At The chart it traces back to the blower motor!

PLEASE Answer the questions above !!! yes the ecu can effect power But need to address the physical issues first! Its a waste of your/our time Guessing At stuff! NEED FACTS

not sure if they changed this in later years how ever check under that PLASTIC panel Three screws and your there! They may have changed to 4 relays as pictured above but the location will likely be similar!

Guttless!!! agree with Nelm put a load on see what ya think! The engine is relatively reliable BUT VERY small working rpm how ever. it has an 18 sp so your OK there,, Mack 18 speed trans is temperamental And expensive to fix! AND your fuel mileage will suck as stated! low ball offer if anything! I would shy away thou if I was you!!!! Your call ! Your Just buying a job and some head aches ! My opinion

yup

The blower motor is shutting ? This is a sign that the Accessory relay Is possibly Fubar!

Sweeeeeeet!

Guessing at 6-8 inches!

Dave I some what agree although, the 12 speed had its place as a dump truck trans with the good selection of reverse gears going for it!As for the 18 sp welllll ! VERY temperamental! and TO expensive to work on! agree on that for sure! Fullers got it all over the the Mack trans for reliability and ease of use! Now they have re engineered the reliability out of the Mack diffs as well they don't hold a candle to the Meritor stuff now! Its truly sad ! Built in obsolescence!

If u have the right hand signal control press the function button and scroll down to gauges press the enter pad and see if there is a test sequence for the gauge panel ! I also believe when you key on the gauges automaticly do a gauge sweep if these gauges are not sweeping it may be the panel is haywire!

Model will help as well RD CH CL ??

A 44000 diff housing is usually Cast ! 36/38 are usually fabricated steel! depending on the year!

Truck model rd?

The low switch is plumbed exactly the same as number 4 (thats reverse they show there) deep reduction has its own circuit same plumbing How ever! The orings in the cyl are very suspect!Unfortunately the cyl is hard to get too you must remove the pass side floor panel ! not so bad in a newer or garage kept unit But if its been used in a salt mine watch out! also there is a line that also goes to the puff limit when Low on the stick is selected to limit Torque output!

👍

So you need to clean or check the vents you not a good idea to run around with the caps loose! 😁

Check your tank vents They should equalize on there own

AMEN BRO!
