I did a little research Monday at the archives. The head size on the new style driveshaft roller bearing housing changed from 5/8 to 9/16 across the flats on June 5, 1924. For those who have tried it, you can't get a socket on the 5/8 style.

Larry

Thanks for that date of change, good info.

This early housing (1923) used the 5/8" head hex bolt and you do have to use a open end wrench.



Later, this one '27 with 9/16" head hex bolt easy to use a box wrench or socket!

Have a mixed set on my ‘26, four are 5/8” and two are 9/16” heads.

I bought a bunch of driveshaft bolts at Chickasha and did notice the difference in the head size on a few of them. The guy was leaving on the 2nd day and was getting rid of cans of bolts and I got a bunch for $ 2.00. And a lot of misc. T bolts to boot!
Nice to know it because of a Ford design change. And yes you can't get a thin wall socket on a 5/8 either. I did try it to no avail.

I wonder how they kept up on the assembly line using open end wrenches on the bolts!

I’ve never had a problem getting a socket on the 5/8” bolts.

13/32" x 16 thread, hex head bolt, length 4 5/8".

Uses a lock washer under the hex head.

Adam, try it again! A socket will definitely not work. Of course if the bolt is not connected to the spool, of course you can get a socket on it!
