Hey Guys
Quick question for the guys that have the tool.

Can you tell me the dimension from the end of the tool to where the threads start? How long is that shaft.

I am going to try and make my own and that seams like an important dimension.

I posted pictures of the tool next to a tape measure in one of the threads in the stator sub forum.

Can't remember which thread tho

Keep in mind, the crank locking tool is hardened to make it stronger. In making your own, if you use the wrong material, you could end up with it breaking on it and that could cause you some serious headaches and $$$ in the end.

TQ

there is a thread here about an owner that tried to improvise a tool and the disaster that followed

IIRC the tool is 50$ which is not too expensive VS the potential cost of a failure..

The tool has a length of 2.935" from the first thread to the radiused tip. The rod is .301" in diameter. It is made by Kent-Moore. The thread is M12 and is .350" long. It is not very hard. The handle is .700" in diameter and is 3' long with a 3/8" hex milled on the end. My guess it is about RHC 35. I would use a 1" bar of pre-hard 4140. It turns very nicely and is the same stuff the crank is made from.
