Default B-29 Superfortress APU engine

I am looking at a Aux. Power Unit engine from a B-29 that is for sale.
V twin, air cooled, 10hp, 2 1/4 bore. It is mounted on the origonal mount, no generator.
Anyone know anything about these?
It is a fantastic piece of engineering, must have cost the government a bundle. It has 600 hrs. on it. the price is $400.00.

BUY IT!!!
If you don't - Send me the seller's name and I will!
I saw one 4 or 5 years ago at Portland and had already depleted my funds to the point where I couldn't take it home with me. When I went back to see if I could have the seller hold it and sell it to me later, he was already gone. I still kick myself over that one.

I purchased the APU engine.
Made by Andover Motors Corp. Model V32
Air Corps Type D-2
It seems to have been moth balled. hr. meter reads 689 hrs.
The hour meter is also stamp with overhaul information:

Depot Date Hours
OCAMA 6-54 UNK
OCAMA 11-56 328
SAASS 3-28-58 0116

The recoil starter cord broke or has been cut, but the engine turns free and is all there.
I am going to need a shop manual to fix the starter and make it run again. Any ideas? anyone familiar with this one?

The duct across the top is to cool the missing generator.
The recoil handle would be below and to the right of the valve cover.
The round thing below left of valve cover is the magneto.

Wasn't that a shame. All that work up in smoke.
They had rigged up a gas tank for the APU that had broken loose during the taxi onto the frozen lake.
The APU was used on every take off until the plane was safely airborne and was started before every landing. This was just encase of engine malfunctions. The tail gunner was responsible for the APU duties.

Hello Mr. Newman....You still looking for a superfortress apu? I Have 4, one that i acquired from my grandpa and looked around and found a few more here and there. I've had the one i got from grandpa running. Sounds like a very small harley-davidson (no kidding) One more complete and 2 stripped but a bunch of spare parts and what nots. Also have a manuel if I can find it. Let me know if your intrested. Leslie

I had one a few years ago and converted it to a welder. Quite simple and worked very good. Somebody took a liking to it one night and it disappeared.

Yes, APU stands for auxiliary power unit. It would likely have been run during takeoff to minimize the electrical load on the normal generators, in order to give the engines maximum power for takeoff. It also allows the electronics to be powered on the ground without running an engine if there isn't a ground cart handy. Most modern military airplanes have one, although today they're typically turbines instead of piston engines.

Leslie, I just signed up at SmokStak and I also have purchased one of these APU's resently. However it is missing the magneto / distributer assembly. Would you have one of these for sale by chance? Would also be interested in a manual if available? Thanks, Mike mpsp44@yahoo.com
