C30 Chassis

[Charlie Down]

I'm trying to find out if the Chevrolet C30 chassis frame was the same as the 134" MCP chassis, as used on the 1533X2 LRDG truck. Any ideas? If there were any differences, what were they?
Many thanks

I don't think so, but please check wanted: Chev CMP chassis views for reference info on the C30/C60S chassis.

My first guess would be "no" with the C30 being 4x4 and the LRDG 4x2.


I don't have a 1533x2 parts list to compare to the C30/C60s but by parallel and looking at 1542x2 and C60L parts books (both LWB), all frame rails and crossmembers have different part numbers from the corresponding part on the other truck. The differences may not have been great but there was something different to cause a different part number.

In general (not particularly in answer to this question) different part numbers can mean just a couple of extra holes in an identical pressing or even an identical part from a different supplier. Or a totally different part.

Agree. Look at the C8 4x4 and C15 4x2 chassis, they differ a lot.

I presume you mean the 1543X2?

Charlie, that would be my starting point for modeling purposes. As far as I can tell the 1543X2 was the LWB version of the 1533X2.

My apologies, it is the 1542X1 and 1542X3 parts lists I was looking at.

Thanks Grant. What was the difference between a 1542 and 1543? Not familiar with the coding system.

I do know X1,X2,X3 etc are export destination codes - see http://www.mapleleafup.net/forums/sh...694#post147694

Edit - from the revised link I learned:

1542x3 3-ton 160" w.b.
1533x2 3-ton 134 1/2" w.b. with 9.00 x 16 wheels
1543x2 3-ton 160" w.b. with dual performance axle and 20x6 wheels and single rears

So the 1542 was a regular 3-ton 160" w.b. truck, while the 1543 was the same but with the Eaton 2-speed axle? If that what "dual performance axle" stands for, that is.

Not sure where this discussion is going but the C8A 4X4 chassis and the C8 4X2 chassis are virtually identical except for the middle crossmember , I've had both types and they clearly used the 4X2 chassis as the basis for the C8A

Maybe you are right. From my recollection when seeing them side-by-side there was quite some difference.

Anyway: do you know "if the Chevrolet C30 chassis frame was the same as the 134" MCP chassis, as used on the 1533X2 LRDG truck"?
