Default 1943 Ford 4 spd truck tranmission- part ID

Good Day,

I found the attached part shown in the photo at the end of the main shaft on my Ford 4 speed transmission as I was stripping it down. Transmission is from a WW2 Ford CMP truck. It could be made of compressed fibre but not sure.

Looking at the 1940 Parts Catalog the part is shown as No. 7064 in the diagram but not in the list. Parts 7063 and 7065 are listed but that number is skipped.

The 1943 F15-A Parts List shows it neither in the diagram or in the list.

I am hoping it was dropped as not required at some stage but I am curious as to what purpose it served. I don't remember seeing it in another transmission I stripped down a long time ago. Would not like to think how hard it would be to find a replacement if it is still required.

Thanks for any help.

Cheer,

PS: Attached photo shows the transmission case painted in Early Ford Engine Green from paint locally sourced in Australia as mentioned in a previous post.

BB-7064 is a snap ring 1.20" ID 1929-42.
The part in your second picture looks similar to a pinion lock lock nut washer.

Hi Bob,

Thanks but the ID of mine is 1.00" same as the threads on the end of the main shaft. It is definitely non-magnetic so not steel.

Cheers,

Jock

Any chance it is stainless? Some stainless steel is non-magnetic.

Hi,

After a closer inspection it definitely appears to be compressed fibre. Broke a tiny bit off with my finger.

The diagram seems to b a generic one as it does not show the threaded end at the back of the main shaft to attach the drive yoke.

cheers,

Jock

Some of the old T8/T9 transmissions have an emergency brake on the back end of the transmission. It may be related to something like that. A lot of E-brakes are band types with s drum. It might be a pad or a spacer.

The CMPs usually have a transfer case. There are a lot of odd parts that go with the old timey transfer cases. There are a few guys on here that have interest in the old CMP Fords. This is a source of some info. http://www.canadianmilitarypattern.com/ There is some transfer case info on there.

Could it have been used to try and stop grease leaking along the splines of the output? I have no knowledge of those transmissions, but Ford used heavy fibre washers at the ends of the rear axle, for instance.

Hi Mart,

I am now thinking the same thing. Mine connects to a single speed transfer case by a small jackshaft.

Perhaps Ford Canada decided the leakage along the splines was so insignificant that it wasn't worth the effort to use them. Time was important for the war effort.

Ford Canada during the war seemed to make a lot of changes on the run. For example two WW2 truck transmissions I have use thrust washers on the countershaft at the ends of the cluster gears. Another transmission does not, so the bosses on the case just clears the cluster gears. Checked this with taking measurements and the case without the thrust washers boss to boss is 6-11/16". The cases with the thrust washers are 6-15/16" boss to boss.

Cheers,

Jock
