Its infectious

[motto (RIP)]

Yes Tony, I've taken some baby steps in the right direction with mouse and keyboard but Maggie and I should have had a family so as there were some grand children around to help me along.
My truck always had 20" wheels and I have not seen many that don't. The first time I saw a L/L Chev with 18" wheels I was very surprised as I had only ever seen them on 20's and I had seen quite a few by that time. The TM's for the trucks that I have only show 20's and one of them has a strip of paper across the cover that is printed in red ink and says among other things.
SPECIAL NOTICE. The 160" wheelbase CHEVROLET TRUCKS imported by the Commonwealth Government for essential civilian users are equiped with:- HEAVY 10" x 5/16" FRAME REINFORCEMENTS, AUXILIARY SPRINGS, 7" WHEELS, 7-7.50 x 20 TYRES AND HAVE AN ALLOWABLE GROSS WEIGHT OF 14,300 lbs.
It goes on to give tare weights for Chassis and cab and trucks with platform,dropside or stakeside bodies.
Don't be taken in by these trucks only having five studs for the front wheels, There is a plate under the wheel nuts that obscures five of the holes in the wheel.
This leads me on to another mystery. The 30 cwt version of these trucks with the 9' tray used a heavier front axle and I mean heavier in every way including king pins and wheel bearings. Bearings are barrel rollers instead of the bicycle type cup and cones on the larger/heavier truck. It appears to be the same axle as under the 4x2 Blitz but narrower in the track.Figure that one out.
There used to be a fellow that drove a L/L Chev around Melbourne up untill about fifteen years ago collecting waste paper. Earlier in his career he had worked for Regent Motors the GM Holden agents and he told me that when the had both light and heavy trucks in the workshop they would swap the front axles over and not tell the owners. Hard to believe but that's what he told me and he was quite matter of fact about it.
There's an awful lot we don't know about these trucks.
You may have noticed Tony that I started a thread so as not to hijack yours. Keep up the good work.

Didnt mind you Hijacking the thread David as it lead onto some interesting discussion.

Which I'd like to continue.

Interesting point you raised about the heavier front axle. Because thats what this truck had (until we replaced it ). The original axle as you said was heavier in every way. The actual size of the "I" beam is bigger, kingpins and it also has barrel bearings. The lighter axle now in the truck has a narrower track and the round bearings. We replaced the axle bacause I couldnt get the 20" rims to fit over the brake drums, which are also different in that the adjustments for the shoes are on the outside (similar to the Blitz stuff if not exactly the same).

By the way enjoying the new thread youve started as well.

Righto David and others. I need some of the vastly knowledgable Chevy fellahs to help me with this.

Here is a picture of the axle that was originally under this MCP Chev. It is set up for the 18 inch military wheels and as David has mentioned above, has all the things he has described.

The brake set up as you can see is a more military set up with the shoe adjustments on the outside of the drum. Different to the set up of the civilian Chevy brakes.

The Slave Cylinders are Wagner Lockheed. Part no's Front FD613 (1 3/8") Rear 5300892 (1 1/2") Anyone familiar with these??

The shoes have no identification other than a part no 3822 R44, and a date on each shoe 5-2-41. The date would seem to provide strong evidence to confirm this was the orginal set up from the factory. One very wise brake guy told me Dodges of the era used the same set up.

Apart from the obvious reasons for posting to expand mine & hopefully others knowledge. I need one pair of these shoes. THE BLOODY COCKY who owned this years ago has removed one set of shoes from one side.

Can anyone shed light on where I might get a set??? Or does someone have some they might sell??

Im getting very desperate as not having these will stuff the whole project.

Calling on the MLU community to come through once again.

The search for brake shoes continues.....

After talking to the keepers of the Chevrolet Flame down at Corowa this year. It seems the common phrasing for these brake shoes in Chevy land is 'Cast Shoes' they are also out of what is known as a 'Timken Axle'.

A further piece to the puzzle was found at Max's at Yass in a Manual.

In the second picture it reveals that only the 1 1/2 ton trucks (or 30 CWT) had this heavy duty axle. Seems to confirm what we thought - that the truck is indeed a 30cwt truck.

The thrid picture decisively shows what these front brake shoes look like. Certainly not conventional Chev, but exactly what is on the front of this truck.
The long and short of it is Im stoked to have found out it is all authentic Chev in the rarer body wieght.....but we are still no closer to finding a pair of brake shoes for it.

Has anyone got any ???? Please??

I think the problem you are running into is one that drove me crazy 30 years ago when I started working on my HUP which of course is Chevrolet I could not find front brake or the brake design or parts in any old commercial chevy parts catalog. The reason is simple they are FORD brakes I only discovered this when I cleaned the brakes and found the little FORD logo stamped on the shoes.

It turns out that most if not all the front brakes on 4x4 Chevy CMPs use the FORD design as well as many of the rear brakes being FORD as well. This peculiarity has been discussed before on MLU I'll do a back search and see if I can figure out how to post the links to the past threads.

Cheers Phil

That might explain why the adjustment set up is exactly the same as a Ford Blitz Phil. Very very interesting, I await your further info with eager anticipation. I'm also told Dodges of the era had a similar set up. I suppose Wagner Lockheed (the brand on the Slave cylinders of this truck) would have supplied brakes for any manufacturer who wanted them. You'll notice in those previous photo's, the manual clarifies the brakes are 'Lockheed type'.

Cman lads, get out the books & manuals and lets find out more!!!

Hi Tony

You should ring Neil Harris......He has some thing for you !!!!

Kind regards

Matt - that sounds like good news.

I must admit to not having Neils phone number - could you PM it to me or send it via Email??
