Hey I resemble that remark. :geek: I don't have a diesel tech (well besides Josh the Adept Ape but he's way over there somewhere out of reach) but if I did I wouldn't let him wrench on it either. Comes down to needing that familiarity down the road for when the day inevitably comes in a...

Yeah I promise you don't want to find the other end of that one. I went there. Wasn't worth it.

Interesting - have you considered reaching out to Red Dot and asking them?

More like $200+ / Hr at most heavy truck shops these days. Of course it depends on where.... at the small end of bear piss creek Arkansas you might could found Cousin Skillet that saw one of them trucks once.... well he fell out the back of it and got med boarded for being permanently cross-eyed...

Check the cab to chassis ground on the passenger wall of the radiator tunnel behind the grill. I HIGHLY suspect that this is what damages the push button switches. Just had one fail on an A1P2 that had a 2v drop across the cab ground strap a few months ago. The push button switches went through...

The governor should unload about 125 psi and reload at about 95 psi. I've had better luck with Haldex governors than Bendix. FWIW. Most are adjustable but some of them they set and then used bolt cutters (?) to cut the adjustment rod threads and essentially lock the nuts in position. I hate...

Right. I mean EMS-NG. And yeah the A0 manuals are scanned into PDF - they are here on this forum for download actually. They were *originally* paper manuals back in the 90's. PDF is really just an e-book reader with some searching ability in this case. EMS-NG doesn't have any A0 stuff that I've...

No. The problem isn't a "shift" harshness. It is a torque converter lockup clutch engagement that you are feeling and the problem is the difference in input speed to output speed at the point of engagement - this is due to the converter slipping because it is not fully loaded, and the clutch...

Nice. I was thinking of the NSN for the cable assembly - since the A0 was a paper manual truck and doesn't exist in electronic TM's that I've run across.

Heck yeah! Let us know what you find!

BAE was doing weird stuff. I'm guessing that harness would be challenging to find in the TM.

The Allison and the CTIS both have J1939/J1708 busses even if the engine does not. Hook it up to a scan tool and see what you find.

Yup. While welding them is *possible* if you know a whole bunch about welding castings.... But also if you are the guy that has the gear to pre-heat, weld, properly cool, and then very likely re-machine them due to the warpage you are also the guy that knows it's stupid when Mike's kit is a...

There were initially some weirdos on Facebook groups that were asking about them. Probably to try to home-brew their own direct drive hubs or the magical thinking of selectable hubs but that racket has died off as even the dullards have realized it's nigh impossible and/or stupid depending on...

The part they listed is the disconnect relay (not the LBCD) - it may or may not actually be bad. There is a PS magazine article on the older disconnect relays with instructions on how to address a common wiring issue with them...

As far as I can tell the springs are the same type. The kits come with instructions that have been photocopied too many times..... I doubt any real thought has been put into this design in the last ~50 years. It's VERY old technology. I worked for a compressor repair and manufacturing company...

Wet tank air has to be continuously supplied to the unloader pistons to ensure the compressor stays unloaded till tank pressure drops below the governor set point - if the unloader piston o-rings leak then wet tank pressure will drop till the compressor reloads. Unloader piston leaks can cause...

Yep. Pretty much guaranteed nearly everyone on this forum has exhaust valve springs that look exactly like that. Except me of course.

Also - just for grins - you should check the connector pin "drag" on the male/female pins for the bus on the truck side connectors - sometimes people overlook pin-fitment issues with connectors and they may have good connection to the wiring but poor grip on the TCM pins inside the connector...

Well - yes you could do that and probably should do that given it sounds like you don't have a diagnostic solution - the real first step and where I would go now is to hookup a laptop (or something like the Bluefire adapter and a phone/tablet) and see if the data it wants is actually on the bus...
