Pony Motor Interchange?

If the 3B9264 block came out of a D2 or D4, it will work. You just have to use the top cover and manifolds from the 5F block. Any Pony found on the D3400, D4400, D311 and D315 diesel should interchange with each other providing you use the top cover and manifolds.

Thanks for the info. I'm not sure what the 3B9264 pony motor came off. I bought it at a flea market for $150 (luckily, nobody knew what it was). I was told by the seller that it had belonged to his late brother-in-law and that he thought it may have came off a D6. I know it has the Early type Eisemann magneto on it, and the exhaust just goes out of the short manifold and does not connect to the diesel intake. This pony motor is mounted on a wood base, I'm not sure why, but one nice thing about it is that the Oil Drain Tube is on it and not broken!
I will take it off the wooden base to check the bottom gear. Hopefully it will be the same as the D2 pony motor. I sandblasted the top cover/manifold last night. Maybe with some luck all of this junk will fit together and I can get the D2 running this weekend. Thanks, again, Rich.

The D6 pony motor is considerably different.....has it's own water pump and there is no bottom to the crankcase sump (relies on the bellhousing mounting) and is considerably bigger and almost nothing interchanges with the D2/D4.
