I have two tools I have been unable to identify. I believe they are "Z" tools; however, no visible marks to indicate that is the case. Any help would be appreciated.
First tool
Second tool

Mark the second tool is likely used to make adjustments to LHD first gear. It fits the external adjuster by the looks.

I don't know the number, but the first tool is the "bar" for removing and installing the brake shoe spring on large drum rear axle. It is shown in the Service Manual in paragraph 1224.

Mark. I'm interested in both tools if you decide to sell them. Not sure about the second tool but the first is a brake shoe spring remover/installer as mentioned above.

The socket wrench is for early engines with main bearing bolt heads with simply 2 flats (not square)

Scott, that's what I love about this forum. One can learn something new every day. I did not know about those early main bearing bolts. Have you any idea what the measurement is across the flats? The square headed ones are 9/16".

Thank you for all the help guys! Much appreciated. The tools are available if interested. I have one wrench and two of the brake tools.

I will check today when I go out to the shop

I'd take one of the brake spring tools off your hands, Mark.

Mark I would take a brake spring tool if still available. thanks Tim

Your early main bearing wrench is 3Z-619. Not all of them are marked.

Jim raises a interesting point. Just when were Z numbers applied to identify the various tools? Originally the large cam gear locknut wrench was designated as part no 2333. The other tools on the same page in my 1915 parts books are all just numbered. There are no Z tools listed.
There is a wrench numbered 2321, but that is for the crankshaft bearing bolt NUT. The Z number as Jim posts is likely a later adoption, but of what original plain number?

Just info from Bruce's C-D encylo. under factory tools he gives rather complete listing of dates too and numbers assigned.

Believe the 3-z numbering began in 1917 or so, with many of the supplied car tools left with normal part numbers, around late '20's maybe '23-'24 all changed to 5-z numbering, except the tools supplied with the cars and trucks. There were many, many 3z and 5z, for almost every thing on the assembly line, even tools to gage one man top iron parts prior to fitting top covering, lots of specialized tools at the factory assembly branches!

That early wrench for 2 flat face main bolt heads is either 2069 in '12-'15 and then became 2341...
and the sq. head style is 2341-B....later in Feb 1917 the 2341-B became 3z-619.

All the nice reason to have on your PC Bruce's up to date encyclopedia


And BTW, that bar for large brake drum shoe spring is 5z-1157 Pry Bar (rear brake spring)

Thanks for the reference source Dan. I can do with more reading!

All of the information about the Ford tools is also in the back pages of "Bruce's Big Black Book".
The main bearing wrench for the square headed bolts started as 2341-B in Oct 1914, was changed to 3Z-782 in Feb 1917, and later changed to 5Z-156.
The early main bearing wrench for the bolts with two flat sides started as 2341, and was changed to 3Z-619 in Feb 1917. It was still available until June 1922, but apparently became obsolete. There is no record of it changing to a 5Z number.

This is an older thread. Did someone on the forum purchase the second tool in Mark's post? I asked Mark and he had sold it.
