That's even happened on my 1-ton Ford Powerstroke with two just batteries. One started to fail and was causing odd starting issues. My pickup is a 12v system and the batteries are wired in parallel in order to provide regular 12v's but double the amps for starting. My understanding is the...

I forgot about the f-word. Not something I worry about too much down here. Follow on question: Does the regular heater like I have operate continuously so I can verify it's operation on warm days by feeling it? Or is operation based on outside temp?

Truck is a M925 (basic 5-ton cargo truck with winch) located in zip 78361 with delivery to 78223. Roughly 155 miles one-way. Truck reported to run fine then developed a knock, hence it being auctioned off. No idea what caused knock so truck may start via slave or jump but not confirmed. So...

First, thanks for the write-up Simp- great info. Second, I'm still learning about air brakes so how does a heater remove moisture from the air brake system? I thought to remove moisture from compressed air, you had to condense it out through cooling, not heating.

I've searched the forum and TM's but couldn't find a good answer. If a M939 has completely dead batts, I know we can slave start it, remove the slave cable, and the alternator will supply the voltage to keep the truck running while also charging the batteries. Back in my younger days when we...

That's part of my dilemma as there are a few equipment trailers with electric brakes. They not very common but when they come up at auction it's usually a good deal since air brakes are preferred. I didn't even think about trailer axle placement but I can see that pretty easily in all the...

Floridianson- I agree air brakes are the best for large heavy weights. And I would generally only use the M923 to pull a 'heavy' load and even then only a few miles from the equipment rental place to the ranch. I, nor my 5-ton, is at the level of Simp who could haul a FMTV from China if it...

I forgot to mention in my original post I don't have access to the truck so I can't just crawl underneath with a tape measure which is why I asked the question. I'm not THAT lazy.:whistle:

On a M939, the brake drum connects to the hub with same studs that hold the tire so you can't flip. A duece brake drum uses the same bolt pattern as axle connection to the hub so you can reverse the hubs. Rear hubs on M939, from the -24P, page 316, fig 315

Moderators- advise if this is not the right forum but I believe the 5-ton forum is the right forum for this post because it deals with how to use/modify/adapt a 5-ton. -------------------------------- I want to buy a decent equipment trailer (GVW ~24-30k) so I can haul backhoes, mini-dozers...

Fuzzy- I agree using a pickup ain't the ideal solution. Just curious if possible due to traction issues. 98G- Looks like you have proof it's possible- I'm impressed. A Cummins inline six towing a Cummins inline six! The crazy thing is your 1-ton truck engine has less than half the...

If a CUCV Blazer can do it, I'm sure a pickup will do it too. On the farm, we towed many heavy things short distances at safe speeds and obviously out of the way of normal traffic. We used a 'tow bar' made by threading a chain through a pipe. When pulling, the chain was under tension and...

I'm talking short distances and very slow speeds. Like using a 1-ton pickup truck to move a 5 ton across a paved parking lot or tow it 10-15mph down a dirt road. I know the towing capacity of today's 1-ton diesel trucks can easily tow heavy trailers on the highway that weigh as much as a M939...

I've search the forum and net but cannot find the axle length (hub face to hub face) for the front and rear axles on a M923. Really what I need is just the offset between the two as I'm trying to understand wheel offsets when singling out the truck. I don't mind mixing steel and aluminum wheels...

How does a shade tree mechanic install run flats like those into a tire? Collapsing it with a strap and stuffing it in? Take it to local Firestone Automotive Shop? Waive a magic wand? I can't imagine it's straightforward.

The stuff here in Central Texas Hill Country is technically Ashe Juniper and it's a wicked weed that just happens to be made of wood. The problem with it is that it will sprout from seeds (the wildlife spreads them everywhere after eating the berries) quickly and grow to 1/2" to 2" thick at the...

The two factors I'm considering about possibility of having a blowout: 1)Most, if not all of the tires, i'll use are military surplus which means they are past a shelf life or have been used by the military...and usually that's means a hard life. And I probably won't be changing them out unless...

Toby- My statement about safety is preventing loss of control if I have a blowout on a front steer tire. The runflat should keep the tire from completely collapsing and causing the truck to immediately swerve. I just need it lasting long enough to get it under control and off the road. I'm...

Gimpy- I'm assuming the kind you have are not the rubber donut without any adjustments. I have no idea how to install those at the house. I also found this thread https://www.steelsoldiers.com/showthread.php?134960-5-ton-run-flat-wheel with some useful pics. I now see how the one-piece rubber...

I don't have a lead on anything. I'm just really curious how to tell so I can be ready one day when I do buy some wheel/tires. After seeing the pain to pull out a run flat from a tire, I can't imagine installing one would be easy for a home wrench turner like me. Thanks Wes- that helps...
