I wasn't able to figure out how to get the drive motor off.
First, I had to disconnect a weird drum brake to get at anything else. Then I removed all the bolts that looked like they were holding the motor on. I put a nut on the end of the drive shaft and carefully tapped on it a little. Not sure what else is holding it in place other than a gasket connecting it to the block it is attached to.
After all that, I decided to remove the big pump motor. It wasn't nearly so difficult, bolt one bolt was nearly inaccessable. It took about half an hour of turning the bolt a tiny bit, sliding the wrench off, flipping it over, wrench a little more, flip it over, repeat....
The big pump motor weighs around 120 lbs, as best I can tell, I had to balance it funny on the scale to weigh it.
The outside measurements are 9" diameter and 12" length
Still, this one doesn't have a real drive shaft either.
