Hey, I got the running pony motor off the parts tractor the other day. Most guys would shut off the motor before removing it, but not me!😆 -Just kidding as usual, but don't you just laugh when somebody is advertising a "Running engine from a _______" for sale? Obviously it's not running now that it's out of the vehicle, and they all "Ran" at some point. Maybe it's been 20 years since it last ran, that doesn't mean it'll run right now without some work. Oh look, my train of thought got switched onto a siding again.

Anyway, I had noticed that the pony motor from the 4U1200SP parts tractor has the name GENERAL cast onto the block under the 5F9341 casting number. I have a few other pony motors here at the shelter for stray Cat D2's and none of them have the word General on them. Does anyone know what that's all about? Could this pony motor be a replacement unit from Caterpillar? Just curious!

Thanks, Rich.

General means it belongs on a military vehicle, such as my 212 grader that is ex army. Better send that pony to me, I'll make good use of it. 😛 lol

That's interesting, I'll look for traces of O.D. Green when I clean it up. I call this a "running" engine but actually it's just "jogging" or "walking very briskly". It has some endplay in the crank bearings and the crank seal leaks, but it should work until I can rebuild of my other ponies (gotta find .020" over pistons & rings for that).

Thanks, Rich.

I was joking about the "General". Figured it was military rank and therefore, military. It was my feeble attempt at getting a free pony. lol. I have found od and marine corps green paint on my grader. Wish that machine could talk. or at least the guy could find the military data plate he removed.

Invisabledog, Yeah I kinda figured you were just trying to trick me out of a pony motor. I'm still curious about that name "General". I have two more pony motors with that same part number cast onto the block and they don't have the name GENERAL on them. ...Hey, maybe that means it was built by General Motors? I'll take it over to my local Chevy dealer to get those .020" over pistons I need!😆

Ag-mike, I bought one pony that was mounted on a base made from a couple 2 X 10's sandwiched together that were notched to let the gear hang down. However, I don't like running a water cooled engine dry so I ran this pony on the parts tractor with the coolant still in it. Wish the pinion clutch was working on the parts tractor, would have been nice to adjust my rebuilt carb under load.

Some foundries would put there name on castings, I have seen that on a early D8 sprocket rim also, a company out of Bellville MI.
