Chevrolet 1533X2 30-cwt trucks

[Charlie Down]

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.

Charlie.

In that left photo with the curved bumper, is the brush guard tube directly above it also curved to match the bumper, or is that just the shadows playing tricks on my eyes?

I think that both those trucks have curved brush guard tubes but possibly the one with the curved bumper is more curved.

I think that the top tubes of the bush guard are both curved, even though the angular bumper version has the bush bar mounted on the central straight section of the bumper. I've checked my references and it looks like the vast majority that I can see from the right angle to discern their shape are curved. There's a couple that look straight, but could just be the angle. Some have rotated so the curve is in the vertical plain, not horizontal. Also found a couple that have no bush guard fitted at all, which I haven't noticed before. I've learnt the hard way with these trucks not to draw definite conclusions, so I'm comfortable to say that the vast majority are curved and there could be some that are straight!
