Turning flathead crank...socket size

[Bruce/CT]

Hi Barners,

Going out to buy a socket for my 1/2" drive ratchet to turn the crank on my resting flathead with some oil in each cylinder. What size? My guess is 1 1/2".
Thanks,
Bruce/CT

Early short crank '32-38 is about 1 3/8, long crank '39-48 1 1/8 deep and thin socket, '49 up 7/8.

Yeah, it needs to be a deep socket, dont ask me how I know. Still, a man can never have to many sockets..

Make a tool from an old starter drive. Works better turning the fly
Wheel. There's a post on here with pics.

Bruce, I bought a cheap 3/4" drive set of sockets, ratchet and extensions from either Harbor Freight or maybe a tool supplier a flea market. It has large sockets that will cover all years of Flathead front pulley nuts mentioned, plus this set comes in handily for other things all the time. I think it was ~ $30.00.
