There's a hole in the pump pulley that will line up with a hole in the
mounting bracket when it's in the correct position to match the cam and
crank. There's a special pin you can buy to place in there or a certain
Craftsman deep socket is supposed to fit nice and tight as well.
Following is some snippets on the subject from my archives. Thanks to those
The 7/16, 1/4" drive Craftsman socket does indeed fit, however, I've
found that using a 1/4" drive older style Craftsman 11mm deep results in an
even tighter fit. There's less than .005" slop. 25 years ago, I took
that socket out of circulation, and keep it for setting injector pumps.
I don't have a loose pump sprocket hanging around, but if you want, I could
at least mic the socket. Advise if you want me to do so.
My Mastercraft 13mm deep socket works great - it's a tiny bit loose, so I
wrapped one layer of electrical tape around it, then jam it in, and it holds
I used a ¼" drive x 7/16 deep socket 12 point Craftsman
