  1. its under the sleeper, follow the fuel tank lines to the center of the truck, they join at the valve.. 2 for the suck side and 2 for the return side.
  2. How'bout I just help you... park the truck on level ground.... keep air pressure bove 90 psi by running it or shop air.... set 2 wheel chocks at a steer tire, 6 inches from the tire, both front and rear of the tire... ( this allows the truck to move for the adjustment) ... then, release the brakes, and let the truck settle..... then dump the suspension all the way... let it rest a minute..... then raise the suspension, till it stops and let it rest.... Leave the park brakes released.. then you measure from the bottom of the frame rail to the bottom of the 'Z Spring' where it sits on the axle or pad.. You take the measurement on the axle that has the leveling valve on it. The correct range is 5 1/4" +/- 1/8"... To make the adjustment you can move the control rod by loosening the clamps and sliding the rod up or down.. If you have a 2003ish and later, there is a slot in the frame rail for a big screwdriver.. you will loosen the pinch bolt there, and rotate the slot with the screw driver to raise or lower the truck.. when you set it, go back to the beginning and check it again.. jojo
  3. What you describe is typically the synchro.. who is doing the repair? An 'in-Chassis' repair is doable, however several essential tools are needed, as well as experience.. I'm not trying to be a jerk, I just have seen many guys who work on other brands, try to do MACK component repairs, and find out they are in over their head.. with respect, Jojo
  4. Are you familiar with how to adjust the ride height, with brakes released and front wheels chocked at a distance?
  5. ok.. good enough,, give me a minute..
  6. since when does Mack need more than the last '6' of the VIN.. Im sorry I dont have the whole vin to re-post.. jojo
  7. do you know the name or series of the suspension?
  8. its behind and above the pedals.. there should be a few of them, I cant remember which one,
  9. I assume you have air ride and want to know the correct ride hieght? do you have AL 405 susp.?
  10. I have no idea how the pictures of some of my trucks made it into my posts.. How do I delete them, and put one that I would rather have on there ??
  11. Uhhh, dont know how my truck pictures got there.. 🤔
  12. Dammit Man !!! 🧠 Power..... 🍻
  13. When you locate the acc. Relay, you can switch it with the headlight relay. If I remember right, it is the same style. Then you can road test to see if the issue is still there.. I'm glad that there was an improvement.. another thing we have done before was to make a short ground strap, and attach it the the EECU housing under a mounting nut, then run it to the engine block..
  14. Did you happen to check the accessory relay in the cab fuse panel?
  15. On the ground bolt in the engine block, is 2 thin eyelets. They are for the engine harness. Did you take that all apart and clean each eyelet?
  16. Has the boost sensor been replaced? If so, was the correct part number installed? Also, have you replaced the little air filter for the VGT actuator?
  17. Yes to the valve under the cab. The hard plastic lines can develope an air leak. The crimp can loosen.. also, check the tank vent tubes and clean fuel caps if they are vented.. The dual suck dual return set up is crap.. I think freightliner had a better setup and they had shut off valves.. jojo
  18. To me... You make a lot of sense Mech.. I think I know what I will do.. I bet I go early retirement, and make side money building engines and trannys.. and selling parts at NAPA, to the guys that need to see and older guy behind the counter... Jojo
  19. behind the cluster to the left is a 6mm bolt,,(10mm wrench) clean them, scrape off the heat shrink glue from the eyelts and throw the start washers away.. same approach at the fuse panel, right side in the cab,, then...... clean the big ground bolt on the engine block in front of the starter,,, (15/16" wrench) if it is loose,, you found the issue.. there is ground cable from that bolt to the frame straight off of it behind the steer tire.. clean the frame ground.. (15 mm wrench). on the firewall next to the starter relay is a black ground breaker..(13mm wrench) clean the ends,check for dry rot and cracks.. then the starter grounds..(3/4" wrench) I assume you checked the battery cabels.. If there is a fused link on the batts,, check it out.. (9/16" wrench) .. Keep in touch... Jojo
  20. Loose ground's.... do you know where they are?? in the cab and outside the cab..
  21. Thank you Hayseed... I looked at it.. I will let it lie for right now.. I'm glad it's not a scam.. I had too many in the last week, so I'm a little gun-shy.. Jojo 🍻
  22. I assume there is an electric plug on the governor housing? It is a duetch plug.. they can develope loose connections, especially if they are not secured in the yoke that is bolted there
  23. There has been more of them sent to me lately than ever.. Just another thning to be on top of.. I guess........ Jojo
