Sir that post is 10 years old. Can you describe the issue you are having, and include make, model and year of the truck. Lots of smart guys on here.

grounds in the cab are behind the cluster to the left. in the fuse panel lower left or right screwed to the cab frame. there is a black ground breaker on the firewall under the wind shield, and on the block in front of the starter, and there is a wire from that bolt to the frame behind the left steer tire. , and of course the battery box. The bulletin had use to remove the eyelets, throw the star washers away, and scrape off any heat shrink glue that may get between the eyelets, and clean the mounting surface before putting the wires back on. the ground on the engine block does work its way loose, and it is the main ground for the engine harness.

I see i posted on this thread, rather than another thread. Anyway, not gray wires... If you can find the 9-2 code svc. bulletin, it has a good procedure. Of course, Heinz can find good info as well..

No clue, i tried also but could not log in. There was a non vendor log in.. What are you try to get? What model and year? Someone here will know, if i cant help

I am concerned about that diagnosis. Unless the engine was abused, like an over speed, or an extreme high temp, i doubt its cracked. I will lean towards EUP o- rings, and then ask to remove the fuel pump and pressure test it with air.. (done it many times) . I have more, but will stop here.

Back in the Mack Pack!

As far as play goes, i seem to remember something about, marking the floor at the edge of the tire, then push the tire at 12 'Oclock and mark the floor again. Measure the distance. 22.5 tire is 1/4" or less... 24.5 tire is 1/2" or less. Maybe someone else can fix my memory.👍 -
Good call Dave.. You are about to here from the 2 Dems on this site now... Well, there may be,,3.. 🍻

Amen..

Check all of the gray wires at the connections, above the pedals and below the fuse panel in the dash, and out on the firewall in the engine bay.. they are the grounds.. Volvo got this right by making the grounds one color..

I was taught the same thing. Mack would only cut the journal that needed cutting. To this day i look at all the counter weights, and bearing numbers.. i dont assume. And Mack bearing kits are not always packed in the correct order. I was blessed to have a cranky old Man take me under his wing... Earl Harnden was his name. Maine Mack, 299 Warren ave. ,Portland M.E. I had to post his name.. He went home a couple years ago..

fjh,, i thank you for the respect. I read this over again. No magic bullet. Was wondering if the o- rings off the turbo to the CAC have failed. They will squeal or scream when boost leaks out..
-
Pull the right seat, un hook the throttle hiem joint, there is a ring of bolts around the pan, 1/2" or 13mm. You will pull the shifter back into a gear, and lift the pan and twist it out.. if this is new to you, it will seem cumbersome, but it will come out. The throttle pedal stays on the pan. Of you still have the heel plate for the pedal, the little screws will likely fight you. This is a good time to drill them out and get new speed nuts and screws..

Was that engine built with 2 pc pistons originally? Just curious, and the year of the engine as well. Lookin good sir

The 2 probes in the x-over tube are calibrated to each other, thats why they are spot welded in place.. -
If it turns out to be the sliding clutch. You dont have to take the whole tranny apart. It can be done through the input shaft hole
-
Yep. Gotcha fjh. Was thinkin about a broken wire .. all good, and i am posting on 2 of his threads, so i may get them mixed up too. 🤔
-
I dont remember, i think it has 3 wires.
-
Have you looked at the wires to the boost sensor in the intake manifold? fjh, makes some good points .
-
Well, i dont know of an adjustment. Unfortunately you will need to pull the main floor pan to get the top cover off to inspect the forks, and rails , and look at the clutching teeth on the 4th-5th sliding clutch. Is this a twin stick or do you have a blue range button on the shift knob (T-2070)? Or just a straight 5 spd.?

Hmm. Programming issue ? I assume its dumping boost when you need Boost -

Sorry bud. Its almost like throwing high dollar parts at it but without a code reader, and based in the steps you have taken, it may be correct. Did you check the VGT actuator for free movement ? The pin in the yoke can seize.. just remove it and buff it clean, reinstall with anti sieze.. -

Its looking like the celenoid. How do the wires look to the brain for it ? Its behind the EECU. If i remember right..
