Probably 12-14 gauge mild steel?

That DCSO truck is like swiss cheese, but I think the battery box is actually pretty solid. I'll check it out Wednesday.

The box and wood battery supports look a lot better than what is in the cab now - the hold-downs and cables(at least the ones that weren't burnt off with a cutting torch) may be useful too.

I took half a day to run to Winslow's and work on the 925A2 today. It was a perfect day with sunny weather to dry out all of the much from the weekend. I did a lot of little projects today. I started by pulling the batteries out of the 925 parts truck so I could inspect the battery box. The wood pieces that support the batteries were nice and solid, but the bottom of the box was totally rotted out. The salt water got the best of it over the last 6 years.

The batteries were actually showing a bit of a charge so I carried 2 of them over to my truck along with the good wood supports. The wood pieces in my truck had totally rotted and turned to dust. I cleaned out the junk and straightened out the cables. I put the good wood in the bottom and set 2 batteries in place. I hooked the battery cables up so that I would be ready to slave start it just in case I made a lot of progress today.

Next, I drained the tranny of it's murky Dexron III fluid. It didn't smell burnt or show any water intrusion so that's good. The bad part was that the drain plug was right over top of the x-member so I had to hold a funnel there the whole time it drained.

Once that was done I worked on some of the wiring. Some Nimrod had chopped off about 8 connectors in the dash including some for the battery switch and the run/start switch. I managed to sort a few out and got a connector soldered back on one of them. I really needed a second person to trace the wires back to identify them since the metal tags were gone.

I quit that project and moved on to installing the fuel-burning heater. I got the control box hooked up, but not bolted to the dash. I need to make a little bracket for it. I got the heater unit clamped down to the bracket and the wiring hooked up, but couldn't do the fuel line since it was a different size than what came with my heater. Arggg.

Since I was stuck there, I decided to put the starter back in and hook up the wiring for it. That was pretty straight forward except I didn't have a 12-point 12mm socket with me to fully tighten the bolts down.

I am definitely making progress. I should have a freshly rebuilt radiator soon and I have all of my hoses, thermostat, etc... on order. That should take care of the cooling system.

No pics today, sorry. I know, bad steelsoldiers!! I promise I'll get some next time.

I sure would like to have seen the pics of how that DCSO truck was used. I remember some photos '03 of a 5 ton plowing through lots of standing water on Hwy. 12

Might explain a lot of things....

Having flashbacks to your last 900 series truck yet? The battery switch and start switch were a bear last time since they had cut them so close to the main harness....

On a crappy note, it looks like we'll be swapping out the battery box. I noticed that several of the loops that the j-bolts hook to were rusted off of the base. Doh! That probably means the cab floor is rusted under the box. I think that truck has had more than a few swims in salt water. Arghhh!!!

Chris, I salvaged the battery box from the parts M925 near here, my intent was to use it as a tool box for the xm757, but it's all steel and very heavy compared to the aluminum used so extensively on the 757...if you can use it, its yours for $50 plus shipping (pick-up?). It does have some rust, but is in good condition.

Thankfully, we only have to trace down 4 of the 7 wires this time.

I already soldered one in place. It was the fat one from the battery, 569 I believe. It won't be bad with one person to stick the multimeter probe in the PCB socket and another to check for continuity in the cab. You'll be happy to know that they cut 2 of the wires off very close to the harness

Thanks Bjorn, but I think it's in about the same shape as the one I have already. I think I can save mine by welding in some new loops to catch the j-bolts. It didn't look quite as bad yesterday since it wasn't filled with rain water and I cleaned all of the rotten wood and rust scale out of it.

My Dad and I drove down to Winslow's today and met my Chad for a work session. We knocked out a couple of seat swaps and a tach install on Bkubu's M109A3 and then promptly waded into the 925A2's dash gremlins.

Chad was a soldering machine! We traced down the last of the gauge and switch wiring. Chad soldered on used ends with the proper wire tags from a parts truck. That will make it easier to make repairs in the future. After all of the fun with the soldering torch, we installed the dash cluster along with the battery switch and the off-run-start switch.

We hooked up some old batteries and ran a slave cable from Winslow's 5.9L Cummins powered M35. Once we had 24v to the cab I flipped the battery switch and NOTHING!! Doh!! Must be a bad protective control box. The sealant had failed around the edge of the box and the whole inside was corroded. The circuit board was fried in a few spots as well. Arghhhh!! Good thing we saved one from the 925 parts truck. We got that swapped in, flipped the switch, and we had power to the dash cluster! Yes!!!

Then, we decided to get the fuel-burning heater fired up. It was a overcast, misty, and generally crappy day so it would be nice to have some cab heat. It took a while for the pump to get a prime, but it finally started pumping fuel. My Dad held a waste jug under the hose for a couple of minutes to make sure all of the nasty old fuel was out of the lines. The line from the pump to the heater started leaking in the process. Looks like the liner has failed. Once it started running clean, we hooked it up to the heater and put power to it. It took about 2 minutes for it to start making smoke, but then it took off roaring and making plenty of heat. Thanks Bjorn!! We pulled the hose off so I could bring it to the local NAPA and get a new one made. It sure was nice to have heat even with the engine still apart. That will be nice this winter for further work sessions and even when the truck is on the road.

I also got the air compressor buttoned up and the power steering pump reinstalled. Once that was back on, I wanted to test the starting circuit. Chad revved the deuce up while Dad watched for sparks. I turned the batter switch on and the other switch to the start position. It cranked right over no problem. Looks like it will start and run great once I have an injection pump on it.

Overall it was a very productive day. The truck looks much better with the dash back together. There is still work to be done with some more loose wires to be tracked down and all of the air lines need hooked back up.

Hopefully Chad will post up some pics after while. He was the official photographer for today. Thanks to Chad and Dad for the help!!

Nice to hear but you must feed the picture hounds.

ATC · 12-27-2008, 03:52

Where is the truck located again? Probably too far away for me, but I would love to lend a helping hand and learn a little!

Looks like you have your work cut out for ya, although she's steadily coming along! Best of luck! I can't wait to see it finished...your last truck was amazing

Will do Chuck. I promise I will do a big photo update the next time I am down there. In the meantime, Chad will provide a few new shots to satiate your photo needs!

Thanks for the offer. The truck is at John Winslow's place and that is east of Halifax, NC down 561 highway. I'll shoot you a PM then next time I head down there and maybe you'll have some time to come shop in John's salvage yard and turn a wrench on the truck.
