Default different inside diameter wheels

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 ) .

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 .

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 ?

Robert you might find a T16 owner who will trade?

It is interesting that our southern cousins used the industry standard bearing sizes in the idler wheel as opposed to the heavier raced bearings in the Canadian carriers. I wonder if the road wheels are the same. The common industry standard for a 40mm bore is either 80mm or 90mm OD, a 6208 or 6308 bearing. The Canadian carriers, and maybe the Australian and British built ones, used the heavier raced 6408 bearings.

Perry, The 40 x 110 x 27mm bearings are employed across the range of carriers British, Australian and N.Z.built) I have no knowledge of the T16 but am interested to know why Ford decided to down size the hub / bearings etc.
I think you might find that the 40 x 110 was considered standard back then? Another factor that some might not know was that the early carriers were fitted with a semi thrust ball bearing (back to back) these were able to be dis assembled for cleaning. The inner idler bearing with the 50mm bore is still a very common bearing. (I'm sure you already know most of this)

That is a really interesting document Hanno, I will have to cross check it with my Loyd engine part number table.

Alistair, go to Nigel Watsons vol 1. pages 210 (pre U.C. and U.C.) and page 211 for Loyd engines.
The No.3 engines were the 90 H.P. engines.(see below)
The EGAE and EGAEA appear to be 85 H.P. (American origin)
The Canadian Engines ( COIUC) were the 90 H.P.
British origin engines were: Variously prefixed:SE51,79E,79F, along with suffixes.
Some British engines wore American ancillaries and generally had 18mm spark plugs while the North American engines used 14mm plugs.
There looks to be about 15 variations across the northern hemisphere war time carriers.
Thanks again to Nigel.

Thank you all my friends. Very informative. I have found thanks to you another T-16 wheel in the lot i had retrieved. In the barn where i found them there were over 100 . I picked 10 including the two useless ( to me ) T-16 wheels. Oh well , we all have to pay to learn i guess.

Default But wait

BUT WAIT A MINUTE ! All is not lost : The inside diameter of the bearing on the T-16 wheel is still 40 mm !

With a bit of mix and matching of bearings and the spacers, I have used t-16 wheels on UCs, and UC wheels on T-16s.
