the Bar Starter 30 years later

Surprised you haven't broken an armature shaft with all that torque. Straight tooth flywheel on that grader?

Why do you have this ? I'm guessing you turn the motor with it - but not start it. Right?

Ingenious. A great use for a bad starter. Nice thing is that if it broke it would be the armature and not the flywheel tooth.

well that wasnt what I expected to see when I read the heading

What a great idea

So the purpose is to get a mechanical advantage to break loose a stuck motor ?

No one else is asking but I doubt I'm the only one who has not seen it before..

thanks guys. 30 years ago i tried to free up a seized motor and in the end i hurt my self and broke a tooth on the flywheel by stilling a bar in the hole and prying. while i was at the hospital getting stitches i came up witht he idea of the bar starter. there are teeth to teeth and everything is centre when applying the power to break the engine free. i never thought my welds would hold on the armature because of the copper effecting the welds but 30 years later the welds are still in good shape.

old magnet -- the motor is a UD-16 which is very different work on because things are just alittle different from a td-9 and td-18. the flywheel is a straight tooth.

as of sunday night the heads are back on the engine and ready to be test fired once the gasket goo is dried.

I wouldn't have given that much of a chance of working if I had seen it when you were building it with the copper contamination in that weld. Maybe it makes it better? You did something right on it.
