Looking for CMP 4x2 information.....

[Bob Carriere]

Looking for a picture of the front wheel brake drum and the beam axle and if possible the guts inside the brake drum........

I am trying to match against the Chev or GMC civilian axles of that period in the 1 1/2 to 3 ton range.

Thanks for your help.

I think it's the same as the 1 1/2 ton

Bob,

Some photos of the C15 4x2 setup here (posts 9 to 12):

I think the C8 4x2 setup is slightly different. At least, different part numbers.

I had assumed they were the same as you say David but the lead from Owen hit the bulleye dead one.... that is exactly the photographs I was looking for.

Convinced more than ever that the civvy one ton axles are similar or very much the same as the 1940 Chev one ton truck.

The main difference is that the C15 has a special adapter on the brake drum to accept the 8 bolts CMP 16 in. wheel/rim.

I will be pouring over that thread in great depth.

Thanks for your help.

Quite obvious that the brake system is civvy and identical to the HUP system so parts are available. Very narrow brake drums with narrow linings even at the rear.

May need to chat with Jaap and Alex.

So important to post our projects on the forum without using a 3rd party posting site.

Thanks again for digging it up for me.

I haven't split my front axle yet (it's on the 'jobs for 2019' list ), but here's some photos of the rear assembly. The C15 4x2 uses the same shoes front and rear. Also some pics of the wheel cylinders.

Bob, Hopefully these will help. Let me know if you have any questions.

As mentioned by Owen, C8 and C15 are different, although the front wheel cylinder is the same.
C8 mostly uses 1/2ton parts for the front axle. Some of the hinge pins and clips in the brake system are the same as GMC CCKW.
