Drilling and tapping 5/8" crank

[Jdominique]

Is it possible? I have a Tecumseh H35 I'd like to put on my kid's mini bike. It has a keyway, but is not drilled and tapped for my 20 series torque converter. Machine shop maybe?

yea, you MIGHT be able to do it at home with a good set of drill bits and a decent drill press, but a machine shock would be much better, they can just toss the crank in a mill, drill it, then power tap it and your good to go.

Well, the crank on my Honda 5.5 is 3/4" and is tapped for a 5/16 bolt. I think this is too big for a little 5/8" crank. Maybe 1/4" ??
