Monster Kohler 24 hp twin K662

[Pullstart 62,922]

So, I’ve had this generator for close to 2 years, bought it for $28 plus some auction fees and tax!  Last year about this time, I tore the Genny head off and set out to see if it’ll run.  It was mostly locked up, so I filled the entire thing with used motor oil and shelved it.

 

Tonight, out of curiosity I pulled it down and it rolls over!  All the way!  Funny, same WICO magneto as the Senior, just a two cylinder version!

 

Now, what to do, what to do?  It was set up as a hand crank start but the pin sheared off, so there is no starter.  Monster kick start?  Big ‘ole rope?  Big ‘ole starter/generator?

@ebinmaine it’s collossus’ cousin engine!

Where is the flywheel? Did it have gear teeth for a starter?

[ebinmaine 67,704]

Big ol bugger ain't it?

 

Can it be modified to electric start?

That big round chunk on the first picture.. that smooth one...

 

it had a big blower housing on the front and a crank start handle.

Here’s a picture of my winning bid, it will show you the big blower

Yes.

 

I’m not sure.

Nice.  That is the second reverse flow cooling Kohler I've ever seen.   
I say you should engineer a way a pony motor can start it like the big green two cylinder machines.  If you would have shared this last summer I could have pointed you towards an complete K662 in the boneyard by me that was still on some manner of golf course mower.

For electric start just put a giant pulley on the output shaft right next to the drive pulley and mount a traditional WH starter/generator somewhere to turn/be turned by it.  

[Pullstart 62,922]

Thought about that.  Bigger pulley on the engine = less rotating speed to start, but easier on the S/G, right?

Somewhere, I did share it here, but I don’t recall when or where.  I was actually just looking at the racking last night trying to figure a way to gain more storage.  This big frame was taking up a lot of real estate just for an engine.  I do have the big blower housing apparatus still, I could keep it set up with a magneto and hand crank...

S/G would be super cool on that but I can't get the vision of something like a little electric start Kohler being the donkey engine. 

[Pullstart 62,922]

I found the original post here.  More pictures and details there...

That engine would be just about big enough for an A-81.

I don't know that you would need to mess with the pulley sizes.  Yes, it's a bigger engine, but it's only hitting one cylinder at a time.  The load shouldn't be any bigger than a 12hp single.  If it was a 24 hp single you'd definitely have issues.

Good point.That's how a golf cart works.

back in the late 70's / early 80's had a summer job at a pneumatic / hydraulic distributor 

 

we rebuilt a large hydrostatic motor from a tug boat (might have been a Sundstrand - but not positive)

 

the 'starter motor' for the tugboat diesel engine was a small block Chevy engine (283 I believe)

THAT would be a sight!!!

Dodge Brothers' cars and trucks in the '20s used a starter/generator to start a four cylinder 35 HP engine.

The SR-71 Blackbird was started by a pair of Buick 401 Nailheads.

[Pullstart 62,922]

Well, this has spark!  
 

it’s unbelievable how massive this really is!  IF (that’s a BIG IF!) it ends up under a Wheel Horse hood, it’ll have a funny set of stacks with the intake on the right and exhaust mainly on the left!

You're gonna need a bigger frame under that thing.

unfortunately I did not see it - but my boss / head of service was on sight to see it 

 

the hydraulic motor was one of the largest we repaired in the shop - recall we had issues installing it on the test bench due to the size

@Tristan Jordan I imagine that 582 is similar size to this 662...

Take a look at the Colossus project thread for the first page or two and you'll see what I'm up to with a very similar engine. I'm not stretching the front of the frame but I am relocating the battery and gas tank.

Keep in mind that's on a spare parts pile of '70s vintage parts and I don't know what the difference is would be considering your 300 series adaptations.
