If it doesn't have air brakes, it's first adjusted at the parking brake drum, if there's an adjuster present. There are a number of cable/drum/handle combinations out there. Is the parking brake drum on the back of the transmission, or the front of the rear end? Sent from my XT1585 using EO...

The computers in these things are actually very customizable. You can have stuff like 2-speed pto settings, remote panel start control, the ability to actively regen while stationary and the pto on, all kinds of stuff. The cruise switch can be programmed to immediately jump to a specific rpm...

I would have a combustion gas test performed on the cooling system. If the head gasket is blown, it will put bubbles into the cooling system that can disrupt coolant flow. Also, I'd consider having either the pto controls wired into the ECU (and have an appropriate rpm programmed in), or...

They mentioned drilling rigs. If you''re pulling up oil, and natural gas is present, then you'd definitely want something like this. Honestly, this problem is relatively rare for over-the-road trucks kept in half-decent condition, and the cost and fabrication needed to install one is probably...

Ouch. Well, you can feel confident that that'll never, ever get overlooked again!

Gone are the days when crankcase pressure is vented to the outside. Now it's routed into the intake. If an engine is very overfilled with oil, liquid oil can be sucked into the turbo, pushed through the intercooler, and then ingested. I've seen engines that have overheated, scuffed a piston...

I would not mix an SCA-precharged coolant with an extended life coolant. Your truck probably came with an extended life coolant, and the one in the pic is an SCA-precharged coolant. I don't know what you have in there. The color means nothing. Sent from my XT1585 using EO Forums mobile app

There are about 3-4 power wires connected to the positive posts on the batteries. One to the starter, two others to power various other things, and the one to the liftgate. There's a very good chance that one of those got overlooked, fell back behind something where it's unseen, and was never...

It ran away and threw a rod. This happens when oil gets into the intake, which can happen if oil is very overfilled. Diesel engines will happily burn engine oil like fuel. They'll spin up so fast it's uncontrollable, turning the key off does nothing. The only way to stop it is to stop air...

What it's doing at this moment sometimes confuses people. When it goes to three bars it starts an auto regen, like you said. When you stop moving, this warning pops up. Basically what it means is if you're gonna park, be careful because the exhaust it hotter than hell and will light stuff on...

Describe what it's doing during the auto regen. There should be almost no indication that anything is happening. Sent from my XT1585 using EO Forums mobile app

Another thing when poking around in there: don't wipe off the face of the burner nozzle. Invariably, carbon gets mashed into the tiny orifices and makes it worse. Ignore face deposits, just spray brake cleaner through it. You'll be replacing it this time around, but in 75k you'll want to try...

It sounds like one of the blend doors is in the wrong position.

This part is normal. If you were to stop the truck and put it in park, it will tell you that an auto regen is in process. If you were to then press the regen button, it will finish by doing a manual regen. Does it ever take a ridiculous amount of time to finish a manual regen, like maybe 45...

Will it do a manual regen? Sent from my XT1585 using EO Forums mobile app

The def pump and injector have nothing at all to do with regens. This truck has a burner for DPF heating, rather than using post injection. Think of it as a large, somewhat temperamental reddi-heater. They need regular maintenance. You often need dealer software to decipher that is wrong. A...

It's my opinion that the steering/suspension on these is not as sturdy as it should be. I've seen lots of problems with bushing wear, steering box wear, etc. The ride quality often sucks. The interiors are made of brittle plastics that are easy to damage when taken apart and reassembled...

The variable nozzle turbo controller is a servo on the bottom of the turbo. It moves a linkage that turns a plate and a bunch of vanes in the turbine housing of the turbo. If allowed to sit, you'll sometimes get some rust on the linkage. Spray the pivot points with nickel antiseize. Granted...
