Info needed: Ford CMP transmission part identification

[Jacques Reed]

Good Day,

I found the attached part shown in the photo at the end of the main shaft on my Ford 4 speed truck transmission as I was stripping it down.

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 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.

Thanks for any help.

Cheer,
