Mr Phillips.......................OH you wonderful man....

Would you have a picture of the brake drum end.....? can you tell if it takes the standard 8 bolts CMP rim...?

.....hope I can sleep now.......

....and yes I might ...possibly ...maybe....haaaaaaa .....consider buying it from you.......

Any idea what and where it might have come from?????

Cheers oh yes ....... Cheers

Hi Bob
The front axle in question takes a standard 16 inch CMP rim to the best of my knowledge. It has a straight hollow tube not the drop type axle in many 4x2 trucks. Many years ago I bought NOS axles from Levys in Toronto, I got two straight front axles this is the one I still have ( could track down the other if you needed it, its a little heavier at th ends) Anyway its yours when the snow melts.

Definitely much interested....as you say when the snow melts ..... I will make a run down your way......... even if it has not melted here in Hammond...... and I might be interested in the other one as well once I have seen the first one.

Getting an axle that accepts CMP rims is going to make the rebuild much simpler and cheaper as it becomes a bolt together projects.

Thank you.

Sounds like an axle from an F602L (or F602S), which were supplied as an ambulance variant.

Bob might need to check the width, as it will be CMP track (70in), and might be too wide for an LRDG truck.

Hi Tony

It maybe but would allow me to use a standard C15a rear axle...same 70 1/2 in. and we plan to extend the fenders.....

According to some preliminary measurements and referenced to CMP books the track of the MCP Chev truck is about 66 to 67 inches in the front and 2 to 3 inches narrower at the rear axle....... which I consider getting close......
I think I can live with that....

I have only seen the round tube axles on heavier trucks..... then there is the issue of spring perch and spring pads.....

...another possibility is that the round tube axle may have interchangeable parts such as the drum/hub assembly with the civilian models...... I know that the rear axle the whole brake wheel assembly can be removed and replaced with civilian dual wheel...drum an all fits..... a very popular conversion on trucks in CANADA post war.

Once I have my hot little hands on the parts I can see what fits or not...

....assuming the snow will eventually melt!!!!!!

PS.... there are no listing of a round tube axle in the GM Illustrated cataloge of MAJOR ASSEMBLIES.......dated august 1944.....?

[Bob Carriere]

...I now know that the tubular front axle is for Ford Ambulance and what it looks like ....some parts do interchange with CMPs and could no doubt be made to fit on a LRDG but much stronger construction and is RHD.

Still Keeping a sharp eye open for other related stuff.

This is a interesting pic. What size are the wheels on this 41 model ?

Hi Tony

Very hard to tell but I would say a CMP rim with some adapter to bolt on to the truck's original bolt pattern.

It would seem that using c15 4x2 axles would be the easiest .....but alas....they are very hard to find.

One option is to have wheels made using a brand new rims and a flat centre piece drilled for the GM 10 holes.....quick fast and$400 each

Second option would be to fabricate a flat adapter from 3/8 steel plate that will bolt to the original GM 10 bolts leaving room for the second set of 8 holes for the CMP pattern .Having available CMP rim much cheaper.

Replace the front beam axles with a Ford tubular front axle which will take regular CMP rims......and a regular C15a rear axle again compatible to the CMP rim. Cheaper rims are avialable any 900x16 would fit.... and a lot sturdier construction using parts we are familiar with.

With the above the rear axle would be slightly offset to the right but not critical I hope.
