X2 on checking the switch. I have also had good luck with lubricating the pivot and linkage and a few drops of air-tool oil in the interlock solinoid inlet line. Three trucks, one had issues with linkage, one the solenoid and one the switch. I think it comes from sitting but once you get her...

Anyone sourced an oil plug drain valve for the 250? Like the commercial units where it screws in replacing the drain plug and lets you turn the flow of oil on and off? I took one of mine in to the local Cummings shop and they couldn't match the thread. Sure would make changes easier if you...

On the rear's I would run it. About tubes in a 14:00x20: Had issues with mine sealing on the rim and finally broke down and took it to a heavy tire place. They swore that a tube would fix it, Michelin ZLs. I thought that was a bad idea but they showed me on the tire and in their books...

Front axles for me. I would like to know from those that have done it if desplining the front axles on a 939 gives similar on-road benefits as it does for the M35. Fuel mileage is of particular interest to me. The trailer discussion is interesting and to that end I would be tempted to simply...

Sorry, edited to show that it is a 939. Ken

I have done a bunch of searching and could find some hard Duce numbers but can't seem to come up with any for the 939 5ton. Can someone with desplined hubs on a 5ton comment on what you have seen in the real world? MPG, tire wear etc? Have issues with bushing wear or? On road obviously but I...

I have some tear-down vids over on NelsonStudios youtube that show the order of mine. Washer in front of the seal, slide hammer to get both out wrecking seal in process. I can also attest to seeing strange random 'hot spots' on several spindles. They looked *exactly* like yours do. I think...

You guys are funny. I wasn't aware the 8.3 got double the the MPG. Mine in the mountains stabilized out at exactly 4.6 MPG. The truck that dropped the liner did 5 MPG. I spend many thousands in fuel each season. Well to be honest a truck a season too but here is hoping that trend stops. As...

Now don't start screaming. I have a 250 855 in a m923 that has munched a liner. I will not be putting an unknown 855 take out in despite how cheap they are because this is a back up to my commercial unit and it has to be a known reliable. So I was going to reline and re piston the block...

I have a 50 inch as well and located it right above windshield height, sort of where you would have a visor but not that far forward. Trying to think if it shows in any of our videos or not. Might need to do a video on how we mounted it come to think of it. Ken

I went through something very similar. I recommend pulling the ground wires off and tightening them back down. I ended up making an additional ground line from the starter to the block out of heavy cable. This was the result of fighting an issue over the course of two weeks, new starters...

The whole bed? That isn't an angle I have thought about. I would have to think about how to do it without making the bed any higher off the frame. I am sure it could be done. Interesting. Ken

For me tire wear is secondary to smoothing out the ride. I am using the trucks in a way they were not designed and currently I soften the ride by running the singles nice and soft, which I realize is a big wear factor. I would only be looking really at taking the center axle out in order to...

They are right about the lock nuts not being what you wanted. I tried those and if you push a tap through them to disable the lock portion they are not to bad but the flange on them, the ones I ordered anyway, was much smaller than the nuts I was replacing. It got the truck home but I swapped...

I have one of these: https://www.youtube.com/watch?v=CYn42tl3yMw Works great. I also ordered new nuts for those wheel bolts but I would have to check the box to get the number. It was difficult to find them in a non-locking version but cheap once I did. Ken Edit: Sorry I forgot that I...

You are right I posted this in the wrong spot, sorry. Maybe a mod could delete/move it? Ken

I tried searching if any one had done this but I just get a wall of switching to super singles. Nothing serious but more than once I have thought about running just the rear most axle of my 939 tourist trucks. I don't need the double for weight and it would save on tires. The idea always pops...

We run a tour company in MT and the last mile or so including the turn around is all LR stuff. I have the front axle auto-engage removed leaving me with just the dash switch. I turn the truck around by driving past a side road and backing around into it, all as I said in low range. There is a...

Are you sure it isn't stuck in 6 wheel drive? Otherwise I have fought tire wear on my trucks with some success. I strapped timbers to the tries so that they stuck out on each side and were level with each other then measured between them. I found you could adjust toe in much closer. One one...

So far I have tried the remove the washer, as shown in the video, and the move the arm methods. If the nuts are gummy moving the arm is an easy fix. I have not tried flipping the linkage, that also sounds easy and could be returned to "normal" easy with just a pair of pliers so next time I...
