Model T Ford Wrenches?

[Mike'smeatshop]

I am not sure you got your answer Lug. But I found a bunch I didn't know I had. But my box ends are both 3/4 and 7/8.

The different box ends are for different purposes. The 5/8” is the cylinder head nut size. The 21/32” is for the rod bearing nut size. The 3/4” is for the main bearing nut size. The 15/16” is for later six cylinder spark plug size. The Herbrand you showed is bent for access to the rear main bearing nuts. The same basic shape of these wrenches was used through the early 1950s, even though Ford no longer made an automobile four cylinder engine after 1931. 1932 introduced the V8, and other than tractor engines, the four cylinder was discontinued.

For both cars and trucks, Ford offered the 50 HP Model B four-cylinder engine (often called the Model "C" because of the letter cast in the cylinder head) in 1932 and 1933 as a lower-cost option, but it was unpopular because of the much greater power of the V-8. It was an improved version of the Model A engine, and was sold as an industrial power unit well into the 1930's. Many were installed in farm equipment, such as combines.

The 4-cylinder flathead was also produced as an "industrial" engine into the '50s and was used on many other implements and devices. Here's an old ad that lists them:

The 4-cylinder engines produced from 1939 to 1952 were flat heads of 120 cubic inch displacement, used on the N-series tractors, industrial engines, and certain commercial vehicles. It was also used in the Ford prototypes for the Jeep program.

These engines were based on the V-8 design, with the larger bore of the Mercury engine instead of the 85 HP version.

Looks like we picked up a bilingual 1-post troll from the ether.

Does anyone actually know the deal on 5Z tools? I usually get the "they're Model A era Ford (& Lincoln) tools", or something along those lines and then some link to an incomplete listing. Every once in a while some unusual one will bubble up and someone will ask a question and get some kind of vague "it's probably a specialty tool used at the factory....." answer. Were people at Ford assigning 5Z numbers to tools after the "Model A's had stopped being produced? (obviously they would have still been on the road) Are there examples of 5Z tools, that by their specific use or are known to be for vehicles produced after say 1931? or legitimate 5Z marked tools where the tool itself was manufactured later than the Model A era?

Uh huh…..crickets….. OK, how about this S in a Diamond logo sometimes found on Z tools?

The Ford tools with the 5Z- prefix part# are commercial tools for the Model A Fords. They were purchased by Ford dealerships and commercial garages and were specialty tools for specific tasks. Attached are some catalogs.

Yep. That's what I saw.
