different inside diameter wheels

[Michael R.]

The C01UC 100300 ball bearings commonly found in unaltered (factory original) bogie wheels designated “CTL 94 A” measure 40 mm. x 110 mm. x 27 mm. There are two ball bearings of the same size in each bogie wheel.

The track adjuster wheel uses two ball bearings of different internal diameters, the larger internal diameter placed towards the hull. That ball bearing, C01UC 100301, is 50 mm. x 110 mm. x 27 mm.

Perhaps you could examine the wheel for the casting marks, as well as any subsequent hand stamped marks applied when the wheel may have been re-tired, or re-rubbered. The details you find may reveal the application. Early narrow spoke wheels were unable to support extreme weights, and were not to be perpetuated by re-tiring.

Straight spoke wheels of standard size can be found on each of the Canadian produced UC models through to serial number 500 of the Windsor Carrier, as well as to serial number 1900 of the American produced UC T16.

I do not have an early parts book on hand that may make reference to the earlier (17” ?) wheel. Perhaps Colin A. or Lynn E. has that information.

As far as I know, all carrier wheels are bored to the same size of 110mm.
BTW Robert, Dress makers use cm.

Here are the only markings on this peculiar 19*inch wheel . The spokes are exactly the same as a regular Carrier wheel . The inside diameter of the hub is 90 mm ( i am not a dress maker ) instead of the regular 110 mm .

Here to the left in green a track adjusting wheel marked FM 42 . To the right the subject wheel in reddish primer paint . Same in every aspect but for different diameter hubs . What is it ?

[Michael R.]

Your first, and so far it appears your only clue: the upper case letters ‘GAU’.

Have look for some casting numbers in the tire portion. They may guide you closer to the G166 southern provenance.

Michael , you are an ace : T-16 ! I have a T-16 track adjusting wheel mixed in with the other Carrier wheel barn finds .... Now that’s too bad because the tyre is excellent on it and i can’t use it . That was the reason i had chosen it out of a big lot of them. What does GAU stand for ?

[Lynn Eades]

Robert you might find a T16 owner who will trade?

GAU is the Ford model designation for the T16 Universal Carrier. The Ford list of designations for government models goes attached. GPA, GPW, G8T and GTB may be better known, and GAU is on that list as well. Did you know GAE was their designation for the conversion of the 90 hp V8 enigne for use in British Universal Carrier?
