Transfer Case ID?

[Tony Smith]

Also the the 2 speed cases used by Ford and Chev, while having the same internals, are different on the outside.

Ford cases have a bracket for the shifter that bolts to the side of the case, keeping the shifter in close relationship to the shift rails, and therefore less likely to "Pop" out of high or low range. There is, however noticeable movement inside the cab of the lever.

Chev cases have the shift lever fixed to the cab floor and a flexible linkage to the shift rails. With heavy body flexing in rougher terrain, this can cause popping out of gear, but no movement of the lever inside the cab.

And there are also 2 versions of each of the single speed cases and the 2 speed cases, with different capacities of oil.

I have never seen a model number reference for any of the CMP transfer cases.

It would be great if New Production parts are available for the Transfer Cases from Meritor!

I would laugh if some parts sales clerk is scratching his head wondering why he is suddenly being flooded with dispatch orders for T32-2 Service Kits by the dozen, when they haven't sold ANY for the last 15 years!

THIS THREAD has some discussion on Transfer Cases, and the similarity to the Ford GTB case.

Geof, do you have any references for the case fitted to the GTB?

Thanks for all the good replies. Please keep them coming!

I had searched this site previously, but hadn’t yet found the links folks have included here. I look forward to reading all of that, as time allows. I just don’t want anyone thinking I’m not willing to do the work to investigate.

The GTB transfer case also looks very similar. I hadn’t see that one yet.

I also hadn’t seen the one with the extra oil capacity. Very cool!

Much of this makes me wonder if Ford and possibly others licensed the design from Timken, but manufactured it themselves. For example, I know IH manufactured multiple axles that were designs licensed by Eaton. They did this for decades.

Interestingly, Timken actually licensed the design from Alma Motor Company and there was a court case in the mid-40’s.

I have only just begun to read the court case, and it is quite a read.

One point that stands out is: "The motion was predicated on an affidavit that Timken had manufactured transfer cases for the United States alone,..."

As stated regarding GM USA/McKinnons, and Ford/Ford Canada, there were a number of Canadian companies that were either sister companies or independant subsidiaries that engaged in Canadian manufacture of US designs for the Bristish Empire market.

Timken has lodged an affidavit that they only manufactured transfer cases for the United States. Perhaps a Subsidiary or licensee of Timken in Canada had manufactured the T32 within Canada, and with Timken being aware on the need to pay Alma royalties in 1940-41 (ie Pre-War in US terms and before the passing of the Royalty Adjustment Act), ensured that the Canadian production did not make use of the term "T32" to avoid triggering royalty payments to Alma on production of the CMP Transfer cases, which by then were being made in Canada in quantities far greater than any Pre-War US numbers.

Geof, time has moved on a little. In that thread, I posted a link in reply#3. That link to a thread is no longer a valid address, so try
http://www.mapleleafup.net/forums/sh...0&pagenumber=2 for a very interesting set of pics, including the transfer case for the Rear-Engined Ford Armoured Scout Car chassis.

This stuff is blowing my mind!

A couple of questions, was McKinnon a company in Canada that produced parts for GM in Canada?

I’ve seen a couple of references to a Company called “Wisconsin” that also produced these transfer cases. Is that the same Wisconsin that used to produce small engines? Any idea what the formal name of that company was?

Thanks for the links and info. I’ve read what’s been posted and linked. I’ll keep searching the site as well.
