Ratchet - who made - what for?

[WNYflyer]

So I picked this ratchet up at a sale today. No idea who made it or if it was specially made then what speciality it was meant for ?

3/8 " drive with push through plug, double flex and only stamped markings on it is "AC" in a circle. It is very stout and well built so whoever made it did a very good job.

Any thoughts Garage Journal brothers ?

Thanks for any help in advance

I'd guess for alignments.

AC DELCO tool, for spark plugs in tight places.

I'd love to see the guts on that puppy. Any chance of you undoing the two screws and posting some pics?

I've never seen one of those, very interesting.

bonneyman, Cranium, AC delco was my first thought also. Googled it and found very little information other than one other thread on another site which showed the same ratchet. Of course the other thread was asking the same questions. I believe you are correct on the AC Delco/Spark Plug thing

bobcatdan is onto something also. The ratchet looks strikingly similiar, at least to me, to some Mac alignment ratchets. I figure Mac perhaps made the ratchet for AC Delco.

Thanks for the help folks

AC spark plug ratchet sold by AC to make it easier to change plugs on some V8 engines. They also made a right angle drive that you put your socket on and then used a ratchet on the end to loosen the plugs. These were around the 1970's that I saw them. Also had an AC tune up machine that worked fair considering it didn't have a scope on it.

Nice rat! Now, clean and lube that puppy up while ya got her open!

Dumb question: Since that mechanism doesn't reverse, do you push the adapter through to the other side to reverse it?

Awesome!
How many teeth on the gear? Looks like it might be a 20.

Yes.

It looks very similar to this MAC set I had for doing alignments on 80s GM vehicles.

Lx460, that Mac aligment ratchet is striking similar, thanks for the photo's. I was looking at that same ratchet you posted in person last night but neglected to get a count on the teeth to see if it was 20 clicks like the AC ratchet.
