CMP ID Need help

[Bob Carriere]

THe leaf spring cab support is typical of cab 13 CMP.....

It would seem that all CMPs came with a winch cross member although most did not have a winch. You might want to take a close look at the bolt holes in the cross member to see if any evidence of scoring done by bolts/nuts is evident. Also immediately behind the winch crossmember on each side of the frame towards the rear some evidence of the wich bearing support brackets may be evident. If originaly a CGT - gun tractor you should have some 1/2 inch curly pig tails welded on the passenger side of the frame as cable guides. Finally your transfer case should have two exiting drive shafts to the rear...the lower driver side one to the axle the other higher to the winch.

How much of the trcuk is left..... I seem to remember a rolling frame???? What size wheels/tires???? on the front axle underneath the engine and the same place on top of the rear axle should be a stamped gear ratio....clean the area carefully.... wipe with a stiff oily cloth.... should help highlight the stamping recessed in the cast iron..... (see picture)if it read 6 over 39 you have 15cwt axles if lower ratio you may have C30 axles.....but then the gear pumpkins may have been changed. The number of spring leaves you describe match my cab 11 15cwt 101" wheel base CMP.

Searching, researching and finding is half the fun...Good Luck
