Chevrolet 1533X2 30-cwt trucks

[Bob Carriere]

Although the part book No 167 does list front bumper (7.825) in the index it is NOT shown either as a picture or a listing in the parts section...... lowest number in the bumper listing is 7.831 ...... bar, front bumper than goes on o the various brackets an rivets/bolts.

The 1940 book no 154 also has a bumper section but starts at 7.831....no diagram and 7.831 is Bar, bumper 2 required...... the rest is all brackets info

Engine crank is 0.239 is listed by itself with no additional info......

The books are like bibles written by different apostles....more or less the same but not good enough by themselves to get you to heaven!!!!!!!

Thanks Bob for your ecclesiastical reply!
I doubt I'm going to heaven anyway!

Its a shame the parts list isn't more forth coming, maybe a bit early although the 1500 series were, I presume, MCP, not purely civilian.
Something will most likely come up.

Ironically the 1972 Tamiya kit had the correct parts in it (although missing the support bars), so I presume the kit was based on a reproduction. If I knew who owned the truck that it was based on I could contact the owner and get photos.
Any ideas?

Heaven is full of CMP mechanics who earned the relaxation.....

Hell is full of the engineers who designed them...........

Are you looking for the brackets associated with the military whatever
C channel bumpers or the civilian ones which where below the crank????

I have a 42 HD Chev. GM in the back field that has a particularly heavy civilian bumper that I have only seen once....... would have to dig it out of the snow but it is not impossible. Only about 18 inches deep before the next snow fall.

Do you know if they have a special vaccine to go to heaven????

Stay healthy.

Hi Bob,
I'm looking for the brackets that raised the front bumper. It was a MCP/military bumper with 4 bolts through each bracket and bumper on each side. Some vehicles used these 4 bolts to attach a D ring plate. A bush bar was standard (So MCP), and the bumper was the heavy duty high 'C' channel bumper with a radiused curve along its length. My research show that the bracket at the chassi end had a mounting for a support rod that went through 'new' holes in the panel below the grill at an angle and attached to the bumper. If you look at the bumper head on you'll see 2 welded bolts either side of the bush bar where the rods connected. I've only seen it on 1500 series Chevrolets, all the 1533x2 of the LRDG, and some 1543 trucks.

Gents,

Ref the question: Did 1533X2 use a two speed rear axle?

Yes, it did. Please see the attached images.

I didn’t realize I had access to information regarding these vehicles or I would have contributed earlier.

Colin, that's brilliant.
There's been controversy about this feature for years, and that's one more ticked off the list.
Just need to find out about the Bumper brackets and the fuel tank cover for the CMP seats (most LRDG 1533X2 trucks had these seats, not the bench seats).

Charlie, by "radiused curve" do you mean curved throughout? If so, that cannot be right, as the wartime photos show the 1533X2 bumpers to be straight, with a angled bends at each end.

Hi Andrew,
For years I thought that they only fitted curved bumpers, then as I got more involved in the research I kept hearing about angular bumpers. I checked my photographs and I'm confident that both were fitted. Its hard to get the right angles, and most photographs look like one version or the other, but its not always 100% clear. However the attached clearly shows a curved bumper and an angular bumper fitted to LRDG 1533x2 trucks. Both seem common and as its hard to distinguish which type it is in each photo its hard to say which one was most frequently fitted.

[Andrew H.]

OK I stand corrected. However I have to say that I have never before seen one with a curved bumper.
