different inside diameter wheels

[Robert Bergeron]

Good evening . Are there two sized inner hubs on Carriers ? I got a wheel that is 9 cm and the other that is 10 cm inside diameter . I am comparing a 19 inch wheel ( front ) with a 20 inch wheel ( rear bogie ) .

Here are the two wheels . One ´s ( the green one ) inside diameter is 11 Cm and the other ( red or rusty ) is 9 Cm . Please advise . Thank you . Bob

I have to add that the inside diameter of the bearings on both wheels is 40 mm . Obviously they exist because we have an example here of each . Would the front wheels come with a smaller hub than the boogie wheels is really my question . I know the bearing have been changed on my front wheel because it was used post war in a factory dolly . Maybe my wheel is not a Carrier wheel after all ? You see i thought all wheels had a hub inside diameter of 10 Cm .

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 .
