And it basically looks about like the V-8 one but with the 1 1/8 (I think) opening. Should be without Ford script, like other '32-3 tools. Easy to find since Ford made circa 5,000,000 of them, mostly scriptless and mostly of course for the Model A...number was changed to B prefix in '32. Don't throw away the V8 wrench, as most aftermarket A-B plugs used a smaller hex that fits the other wrench!
Hi, I just checked my collection of Ford tools and I have four of those wrenches. I probably don't need four of them. They all have the circle with the M in it for the manufacturer's mark, no Ford script, the 1 and 1/8th inch open end for the plugs, and approximately 3/4ths inch for the boxed end. The wrenches are approximately 10 inches long cast pieces with the bend up for the spark plug end and the bend down for the 3/4 inch box end. The only difference in each of these is a number in raised numerals on the back side of the wrench near the boxed end. The numbers are 44, 47, 52, and the number 4 which is smaller in size and a little further away from the boxed end than the other three numbers. I assume these are just casting numbers (but if they have significance I'd really like to know about it). PM me I'm sure I no longer need 4 of these. Hope this additional info helps. Toby

I have 2 of these, they both have B 17017 plus Ford script on the underside of the handle part.
Exactly the same as the Model A ones but most A items have no script or part #.
The V8 one marked 40-17017 looks somewhat different.

That is the correct number, should be 1 1/8" open end for plug with 11/16" head nut at other end. "Too small" is strange...1 1/8 is I believe biggest plug hex Ford ever used.
What size does it measure?? What do the plugs measure?

Hex on that wrench should be .6875 for 11/16, fits all 28-48 Fords head nuts except v-60...
Open end should be 1 1/8 for the original plugs. Most aftermarke A-B plugs are smaller hex than the originals, and most actually fit the '33 V8 wrench.
(head nuts 11/16, Ford book specs the hex wrench a tad loose at 45/64, still a lot smaller than you measure.) This is something odd, possibly modified?

And that should be too loose to actually use on the head nuts. Get another wrench...
Is plug end normal?

It is a shame. I only bought this to use on the spark plugs. I would use a regular rachet set on the head bolts if needed. But I figured this would be the spark plug wrench. What the heck size spark plug rachet would i need for Ford 4 cylinder Model A spark plugs or Model B 4 cylinder plugs? I am so confused. All I want was a way to remove my plugs!

I'll have to measure one at home, but I think 1.125 plus a little slop would be right.
It should fit original Champion C4's (number from memory, might be rong), which as far as I know are biggest hex carb around for a-B Fords. Other brands and modern replacements are generally smaller, usually the size of '33 V8 wrench, a few are stock size, I have never encountered one with larger than stock hex.
Meanwhile, until you get a B-17017 wrench that is the size it is supposed to be, you can generally getemout using the Ford monkey wrench in your tool kit.
