CMP front wheel bearing shims

[Tony Smith]

My understanding in the difference in C11Q-1193-A,B, C, D, etc and C21Q-1193A is that the 1941 pattern used several different spacers in different sizes to suit, while 1942 used only one spacer of a standard size, but built that up with different shims.

I suppose someone thought that keeping supplies of multiple sized spacers was more of a production or logistical supply problem than having only one spacer and supplying shims for adjustment.

Hi Tony,

That makes a lot of sense. My parts list is Dated 1943 and only shows the Cab 13 but I would think they would just carry on parts from previous model years if already in the system.
Looking again at it there is only 0.060" difference between the shortest and longer spacer. well within the realm of compensating intermediate sizes with shims on a standard 2.060" spacer.

Cheers,
