Cargo / Dump conversion project

Postby 42cargo » Sat Mar 10, 2012 4:25 pm

The unusually warm winter in Texas this year has enabled me to make some decent progress on my project.

I'm trying to work from the bow to the stern, sandblasting and priming parts as I go along. Those that don't need any welding repairs are getting a first coat of OD. The others will have to wait until I buy a welder and get 220 working in my shop, hopefully in the next month or so.

Today I got a bit sidetracked on dealing with a fuel line leak, but I was able to strip out all the windows in preparation for getting new glass.

This truck was really in great shape as far as rust when I got it, so the cab and associated parts are not going to need a whole bunch of work. The bed, on the other hand, has been badly dented over the years as is the nature of dump trucks. (The original cargo bed was straight as could be. That ended up going on a former auger truck in Utah.)

I toyed with following Dave's example and building a complete bed from scratch, but I decided to restore what I've got. The local sheet metal fabricator is bending some hat- and u-channels that I'll use to make all new stake pockets and he's also forming up some heavy gauge channel that I'm going to use to replace the outer lower rails on the bed. Those parts should be done in the next couple of weeks and I'll take photos as I start grafting them in.

I tore the 1944 235 down that I bought from BobC out in Arizona. It was as clean as could be inside. Machine shop boiled the block out and said the cylinders are all at original specs and the crank and cam shafts were likewise in good shape. That was great news.

Looking good, John! Can't wait to get mine to that stage! The warmer weather sure helps out. Are you using a sand blasting cabinet or are you doing larger parts with a mobile unit?

Hi Farrell,

Thanks for your note. I'm using one of Harbor Freight's portable units. Works great, except the ends on the deadman handles wear out quickly from sand hitting them when you go from on to off. The local outlet doesn't sell replacement parts, but the main distributor in California does, so I've got a bunch of those coming shortly. Once I change the ends, plus add a new porcelain tip, I should be good to go for a while longer.

We have a long weekend coming up at work, and if the weather's good, I'm hoping to get the cab all primed. That will be a major milestone.

Finally got my shop wired for 220 and have been using my welder to address stress cracks and holes in the truck.

I had the local sheet metal place fabricate some stock to use to repair the damaged sections of the bed. Made the first stake pocket and am pretty happy with the result.

Image

Plan is to keep concentrating on the cab and getting that all primed, painted and reassembled. I'll then lift the bed off, clean up the chassis and axles, and set to work on welding new panels into the bed.

It's a ton of work (as you all know) and I had one of those "what the heck did I get myself into" moments this weekend. But I attached some of the front clip parts and that made me see a bit of light at the end of the tunnel.

Image

The rate I'm going, I'm hoping to have this at a point where it's all painted and together by the end of the year. I'll then have to rewire it.

It's looking great and is coming right along. I'm sure most of us can relate to those dark moments half way through a big project like this.

The civilian front end sheet metal on the truck was a very interesting , I've often wondered just how that would look.

Hi John... Nice BIG shop you got there to work on it!

If I had a garage/shop like this to store my completed Chevy, I wouldnt have ever sold it.

Thanks, Dave. It sure is a change from when I was living in Los Angeles and either had my stuff outside or in one half of a two-car garage.

Funny thing though, the larger space has not made me work any faster!

It's starting to look a bit more like a truck.

Got it fired up this weekend. Engine runs well, didn't give me any issues after I primed it a bit.

Brakes are sticking once the engine's running. (They turn freely when it's off.)

I'll go through the following to try to isolate the issue:

1) Disconnect the vacuum line to the hydrovac.
2) Check the valve on the hydrovac line that's mounted on the firewall.
3) Recheck toeboard clearance.
4) Re-bleed brakes, particularly the hydrovac rear nipple.

John,

Your truck is looking fantastic! I had forgotten that you had all of the troop carrier parts. It looks like you have found all of the parts needed for a fully restored truck. Not many can say that. I am certain that it felt good to hear the engine run again.

Thanks Paul.

Yes, with the exception of some small parts like the original PTO driveshaft support bearing, the splash guards around the engine and the bracket to mount the suppressor to the generator, this truck is pretty much complete. (Well, other than the wiring harness, which totally needs to be replaced.)

If the weather is decent this weekend, I'll post some more photos and video of the dump in action.

Looks like a Hercules D12S2 dump body. How did you stumble on to it?
The lower edge was wasted on my bed to. A 10 ft. press brake was difficult to find around here.
I used a 10ft. section of square tube, the same width, same gauge, as the edge. I split it length wise. 1/8th inch in from the top radius, 1/2 from the bottom radius,or what ever the lower edge is. Flame cut it with a sheet metal tip. Plasma would have been better, i dont have one.Cut out the old welded in the new. Turned out good. You have to look hard to notice it was messed with.
Your truck is coming along great.

John,
You often comment on how slow your restoration is coming,Well I guess there's something to be said about taking your time and doing it right. Great job, I really like the troop seats and top bows.

Thanks for the comments. It has now taken me twice as long to get this far as it did for the Allies to prevail in WWII. (Unless you start with the Japanese invasion of Manchuria, which I know would technically be cheating.)
