Our LRDG Chev

[Andrew H.]

We are now making our "bush bar" or "scrub bar" (I am not sure what the correct term is) to attach to the front bumper. Judging by wartime photos (see pic attached), the LRDG appear to have used the same type of bar used on all of the Blitz type of CMP trucks. Can anyone tell me what diameter the horizontal pipe or bar is? I assume one inch?

Nobody responded to my query (above) about the bush bar or scrub bar. Maybe it was a silly question, but I still need to know the answer. Could someone please measure their original horizontal bar and tell me its diameter? Thanks in advance.

Im working on making one of the brush bars. I will get the diameter and wall thickness for you tomorrow. I will also post some detail pictures of the parts.

Picture #1
The bar is 36" long, outside diameter 1-1/8", inside diameter 3/4" The ends each have a stopper on them. 1/4" thick, outdiameter 1-1/2", inside diameter 1-1/8" They are welded all the way around on the inside edge.

Pictures 2,3,4 and drawing
The metal is 3/8" thick, 2" wide flat stock. The drilled holes are all centered on the 2" width. They have a diameter of 7/16" The measurements for the bottom pictured brakcet were taken from the far right end of the bracket working left to each hole's centre. The top pictured bracket I only measured the first hole from the left end. You can then bolt them together to get the holes all lined up. The bolts that went through the bumper also had spacers to act as a stop for the bracket on the rear side of the bumper.

WOW!!
Thanks Jordan for your comprehensive reply! That will be a big help.

A little more progress yesterday. As suggested in some other threads, we have now ground off a narrow strip around the split rims to make it easier to fit the tyres (that is, when we can find suitable tyres! ). After sandblasting, the rims received two coats of primer, a coat of gloss enamel and later they will receive one coat of matt desert colour.
Then we started assembling the gearbox. All the bearings and seals have been replaced except the roller-bearing, which was replaced by a phosphor bronze bush (that size of roller bearing could not be found). We are still missing the "oil slinger" at the output shaft, and hope its not needed as we are using sealed bearings. We decided not to bead-blast the cogs and have just wire-brushed them, leaving some surface rust. Not happy about the rust, but when the truck is mobile we will drain the gearbox after a short run, to get rid of any small particles. The gear teeth are slightly worn, but at least none of them are missing!

Hi Andrew

Would not be to worried about the rust on the gears, both of my C60 transmission had rust and pitting, I just polished the gears, on my transmission they are a little more noisy. The C60S went about 20,000 miles before it broke a tooth. On all of my transmissions added a magnet to the drain plug.

Your truck is looking great, have enjoyed watching your build progress.

Cheers Phil
