working on old caterpillar's 

only one is a flat head. the 2 ton is a OHC motor for the 1915ish

Agreed. I've just been around the old Lincoln gasoline flat head welders years ago and never around those tractors, except for a D-2. Then it was 4's and on up. Those tractors had to be in good shape or you would've worn the crankers down to nubs! GOOD Job!

aw but they do;) the pony motors on the RD6 D7 D8 D9 all have hand cranks lol

And the 2's and 4's, the graders, pans and all the power units back then. You wanted to crank a Cat you had a pony motor to deal with. Some with a cranker and some with a rope start. Those were the days.

You should get a Cat with a pony motor. You've lived a sheltered live, even with Baily.
