M88A2 Hercules APU

[jesusgatos]

Anybody know anything about these units? Looks like they use a HATZ 2G40 two-cylinder diesel engine, have a 300 Amp 28V alternator and a Bosch hydraulic pump of some sort. Would love to know more about these things, as I just struck a deal on one but haven't even seen it yet.

Hey this is my hang out
Pics coming soon.

Awesome. Looking forward to finding out about these things!

I can tell you it's a generator/APU out of a large tracked wrecker, which was built on the M1A1 chassis. the engine in an M88 Herc was a V12 Diesel but that's not the one that runs the APU..

, which was built on the M1A1 chassis. the engine in an M88 Herc was a V12 Diesel but that's not the one that runs the APU..

M60 series... not the M1 series chassis............. Considering they've been in service since 1961.............

The M88a1E! & M88A2 are upgrades to handle the M1 series..... but it's still the same Chassis.

Yup. I almost posted "the originals were built on the M60 chassis, and later models were built on the M1 chassis..." but honestly, I'm a medic and was going by what a track mechanic had told me. thanks for the correction. I know they've been around for-freaking-ever. I love em though, they're big and noisy and they can do a crapload of work. good find on the APU.

They were gassers when I was in. Unreal. An air-cooled V-12 with 4 magnetos to fire the spark plugs, 1200 cubic inches, and 1500 horsepower. The exhaust was blue at night.

I raced one, once. I was in an M113 towing an M113. He was towing an M60, M551 (Sheridan), and an M113.

He stomped me into the dust.



Must have been that APU helping him out.

Couple crappy pics.
Jessie, on pirate4x4 general chit chat I started a thread and found some active duty Army 91K track vehicle mechanics. They will know some specifics when you get to working on this.

I don't know about the APU in the Hercules model, they just started fielding them when I was getting out. On the A1 the starter generator is the same as what is used on the 4.2Kw 28Vdc gen sets.

The 2G40 looks like a current production engine. Some info comes up on searches and there seems to be a few in the marketplace.


Did you get the two take outs that went recently at Warner Robins? I saw those. They looked like a decent gamble.

The mounting arrangement looks weird and some work may be needed to reconfigure them. Or just strip out the engine and do something with it.

What are your plans for it?

Munchies is hooking me up with one and it's going in the M103A3 trailer that I'm turning into a mobile workshop / toybox and will be towing behind my M109 motorhome.
