Canadian transmission

[Deuce Man]

I have a Canadian engine in my 46 ford, I think the transmission is Canadian also. There is a vent cast into the bellhousing that goes down into the inside of the gearbox, with a little steel tube sticking down inside. My question is, what is different about the inner stuff? We would like to freshen up the transmission while I have it out for a much needed throwout bearing change. I just don't want to buy a lot of parts that will not work. Thanks Rich

Give Mac VanPelt a call for parts. He literally wrote the book on the pre 1951 cog boxes and he hasn't ever given me a bum steer.

Seems I remember seeing an early trans with a grease fitting that went down a flex hose to lube the thro out bearing. it's been a long time. Walt

First off, the thrust washer on the lower cluster is different, Van Pelt asked for pictures, to see if he can match something up to it. I wonder what else is different? Rich

It might be a little easier to understand and consider what you're asking about if you'd at least post a couple of pics. You indicated it's out of the car and easy to see. DD

Check the serial on transmission case, which can be done whether it's US or Canadian built trans. I think you are seeing an early vs. late difference.
From memory...early, like 1940, sideshifts have a sort of cast in vent tube that goes up the bell housing to the area of the access plate on right side, while later transmissions have vent down on front of gearbox area with a little mushroom fitting covering the exit.
There is indeed an oddball Canadian thrust washer, which I think is pictured in the Canadian parts book. I had a long correspondence with someone on HAMB trying to figure this out...

Bruce, you are on the right track. I will post some pics tonight when I get home. Thanks Rich

Here are some shots of my transmission. The number is 1A7942 , any ideas? thanks Rich

This is all I have ever found on Canadian serials...notice that nothing seems to quite match, but I suspect it is 1940 somehow. Canadian serials are low because they made changes in prefix frequently rather than using one numerical sequence for an entire engine dynasty like us.

Although it may not make sense. 1A prefix may have been 1940. 2A is shown for 1941. It may have been later in the year. I know Canadian production wasn't as high as the USA output. Canada seemed to like short numbers so they would add an alpha number after the prefix so that they could start the number sequence over. There never seemed to be any meaning to the alpha numbers either but who knows?

I'm quite sure that vent is 1940 only after that Ford used a rattle cap vent over the gear box area............Kube will know..... I have remachined the US rear thrust washer
to accept the Canadian cluster. No big deal.

Charlie was your Canadian cluster similar to mine? Mac Van Pelt has a thrust washer that is modified for a Canadian cluster, still isnt exactly what I have. How exactly did you remachine yours? Thanks Rich

[Bruce Lancaster]

That is not the oddball one I discussed a few years back. I think that one had a sort of figure-8 imposed over the central hole?? And, I think I found an actual picture of it in the Canadian parts book.

[Deuce Man]

Has anyone in Canada rebuilt their side shifter transmission? If so how did you deal with the thrust washer issue? I'll bet there are a pile of these things sitting in some ones garage, question is where? Rich

Any help is appreciated. Rich

I have a'40 Canadian and did my trans. Same issue with the vent and the thrust washer.There is the normal USA washer, same thickness and construction, but with a round hole the size of the shaft. I took that one on my CNC mill and made it into a Canadian. Still have the pics and the program(G code)
Will post pics tomorrow.

[avrotom]

Duece Man, found the drawing but G code was erased, but my CadCam guy says its an easy one. I will try some pictures here. Can't find a pic of the finished product, its now in the transmission. The thrust washer with the round hole is the same thickness and OD as the "Canadian" one, and easy to get. I included a shot of the "new " pins in the levers. I made them of SS. Its sure good to start getting things back together. Just finished the Differential assembly.

Avrotom, Thanks a bunch, this gives me a little more confidence, to do what my intuition told me to do, but was afraid to do. I don't mind doing a transmission over again if something doesn't work out, its just that Henry didn't make a very easy task of getting them in and out! Rich
