Canadian M37 PTO

[dotgain]

Hello, I am new to this board and also M37's, bought two CDN's a 1955 and a 52 parts truck back in November and have been cleaning and painting parts since then… doing a ground up restoration.
These are great trucks to work on and I'm having a blast.

I am looking for a PTO as I want to put a winch onto this truck, from what I understand the PTO is different from the US version (but please correct me if I'm wrong).
The trans is a Acme T98, the PTO that I need is an Acme 4867. The access plate on the trans looks very similar to the NP trans… Is there a way to put a NP PTO onto the Acme T98 as the CDN PTO seems hard to find.

Any help is appreciated.
Thanks,
Paul.

I have a CDN M37 with pto and winch and I believe that the Canadian ACME pto is not compatible with the US Trans.
Of course I could be wrong as I am no expert!

They are like hen's teeth to get hold of too.

Thank you for the reply… I am wondering if the Borg-Warner T-98 trans is the same as ACME T-98 trans?
There does not seem to be much information regarding a ACME T-98 trans.

Yes, I am afraid there isnt much info around for it. I'm sure one of the other guys on the forum will help you out soon.

I might be onto one but need to know pto rpm at a certain engine rpm to drive a Braden LU-4?

It is a Warner T-98 right down the line. The PTO is exactly the same as is used on the New Process, with the possible exception of the idler gear. That too may also be the same, I'd have to measure diameter and count teeth to be certain.

Well I answered the rpm question right out of the manual, 395 pto rpm @ 1000 engine rpm.

My compatibility issue came up when I read this thread…

Charles there you mention that the Acme pto is different and requires a specific pto.

If the ACME trans is the same as a Warner T-98 then that should make my search easier, is this the same as Borg-Warner T-98? Could I just reference this trans and output rpm to get the correct pto?

Thanks for all your help.

I don't have a PTO in my hands that came from the Warner T-98 at this time. I do know the case and internal make up is the same. Since I don't have one to compare the idler gear with the PTO idler from a New Process; can't be 100% there. I have a Warner trans, but no time at the present to try the install of a PTO from a US M37. That would answer the question finally. I simply can't recall what my statement from the above post you noted was based on 100%; memory just doesn't click like it once did.

Yes, thats the thread I was thinking of when I mentioned that I didnt think they were compatible. If they are then thats good news for all Canadian truck owners I guess.

Here is a snipit out of my Canadian manual.

Dotgain,

I has a US model M-37 but I know the Canadian ones has some different features and I've been thinking of trying to get a manual for one so that I could study them. How hard is it to find a Canadian manual and what do they usually costs? Do you have a suggested source for them?

Have look here, most of the Canadian Manuals are there for you to download for free :

Thanks Stu, great place to get manual copies… I downloaded these a month or so ago and had them copied and bound, made two copies one for the shop and the other for when the one in the shop is no longer legible:)
I heard today that the offset of the output shaft is different on the Canadian truck PTO to get around the oil pan?

I searched for a CDN PTO idler gear for years. It turned out finally that VPW had them on a shelf that they got with a load of other stuff and didn't know what they were. I bought one and gave them the CDN part #. The diameter is the same as well as the # of teeth, but the gears are cut at a reverse pitch in relation to the US idler gear. (to mesh with the 3rd speed gear) As far as I could tell it was the only difference. Otherwise the PTO parts seem to interchange between cases.

You nailed it; I had a US PTO down yesterday; I was thinking that was the way it was on the Warner trans, but just couldn't get settled in my mind to be sure and didn't want to steer anyone wrong. With your post and what I already knew; I'm satisfied now that the only difference is indeed the input gear.

One other thing I can add also, there is a mistake in the manual info that is posted above. It states the number of gear teeth as 36. That is incorrect, it is 26. Also the gear that is pictured is not the idler gear that has been in question here; the gear that is pictured is the reverse gear.
