Ford Wrench Identification

The size and part numbers never appeared on the wrench. This was also painted black. There's also another smaller opened end wrench what went with the toolkit. A-17015 (7/16" x 1/2") was the size.

The wrench is correct for the Model A tool kit and is also correct for N tractor.

HTH,

The spark plug and cylinder head nut wrench (A-17017) was manufactured between 1928 and 1931 for the Model A tool kit. The Ford script was optional after April of '28. So you might find wrenches without the script. It was painted black. BTW the price for the wrench in 1930 was 35 cents. :-)

This wrench went through many design changes through the course of years due to the changing of spark plugs and hardware configuations.

In 1932 the tools were given new part numbers with "B" in them. B-17017 was used through 1934. The B-17017 is harder to find these days. These wrenches were painted medium gloss black paint.

40-17017 wrench was used from 1933 to 1938 on V8's that used 18mm spark plugs.

In 1938, Ford changed to the H-10 plug and the plug size was 14 mm. So they redesigned the wrench and named it 81A-17017.

In 1940, the wrench was redesigned again to 2 different wrenches. The first 01A-17017 (head nut end had a 12 point instead of 6 point opening), and then to the later common 01A-17017-B. This wrench as we know it has a box end on each end. The "B" suffix wrench was used until 1948 in V8's that used the 14 mm plug.

That's about all I have. Sorry for the long drawn out explanation.

Thanks to Ed Gooding for supplying me with literature to these fine Ford vintage tools.

Ron wanted a date and usage so I elaborated with a convectional retort.
