Chevrolet 1533X2 30-cwt trucks

[Charlie Down]

Hi Bob,
I'm trying to get details of the bumper brackets. It looks like the 1533 and 1543 had solid brackets that raised the bumper to allow the starting handle to pass through the bumper, not the lower spring style civilian brackets. Is there any information in your 1543 parts list about these brackets or is the 1940 edition too early for this detail.
It also appears that there were supporting bumper rods outboard of the brackets that attached to the bracket on the chassis end and went through separate holes in the panel below the grill, before attaching to the bumper.
Trying to clear up this detail.

Many thanks

I would have thought that the reason for raising the bumper was to get it further from the ground as the vehicle was to be used cross country. That would have required the starting handle hole to be in in the bumper rather than above it. There would have been no motivation to have the starting handle go through the bumper otherwise.

Sorry, that was badly worded on my part, the bumper was raised to give greater ground clearance, which resulted in the starting handle hole now locating in the top of the front face of the bumper.
Apart from the 1500 series of Chevrolet trucks these bumper brackets don't seem to have been used on other trucks.

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.
