The bell housing measures about 22 inches across.

Aaah that engine is set up as a marine engine .
I bet you don't have a keel cooler on your loader.

That red engine sounds a bit lumpy at idle speeds similar to what I think I mentioned about the one in your loader a long time ago. It could just be the recording but the audio on that recording sounds like it came through pretty well to me. A good running 2 cycle engine always has a nice even and clean sound at any RPM.

He thinks I need to leave that on there, I told him it would come off and I’d set it up the same as mine.

We thought it sounded really good. What do you mean by lumpy?

 

[mountainguyed67]

What about my other questions above? I’m ready to buy this thing if you guys think it’ll work. It’s a number 7 arrangement, same as mine.

 

[mountainguyed67]

One problem I see is the placement of the turbo. Were some turbos placed differently?

What is on that motor is a expansion tank , a keel cooler is a heat exchanger in the bottom of a boat.
If that motor is really set up as a marine engine your loader won't have nearly enough radiator.

Option plate says it’s “power base” application, it has a 4 in the 4th digit place. Marine would be a number 2 in the 4th digit place.

Bluox knows his stuff. I’d defer to his comments. And yes turbos were placed in many variations.

 

[mountainguyed67]

Bluox knows his stuff. I’d defer to his comments.

He’s saying it’s set up as a marine engine, the option plate says otherwise. I’m thinking the marine engine is a different block, am I right? So it’s a power base that’s set up as a marine engine? Plus he hasn’t said anything about its condition.

 

[DB2]

Well Birken V has noted it sounds funny so there’s that. Hard to determine an engines actual condition without seeing it in operation. I’m not trying to dissuade you just keep you objective.

Well then it might be a former marine genset .
If its a water below port block you may have difficulties swaping parts.
Don't let me slow you down. Carry on.
Good luck
Bob

 

[mountainguyed67]

If its a water below port block

How would I confirm that?

 

[mountainguyed67]

He says it was set up originally to pump water for fire sprinklers in a high rise building, they only removed it because of emissions requirements.

 

[mountainguyed67]

Can I scoot the turbo over, or is that another thing I need to find that’s just right?

 

[mountainguyed67]

Is this engine supposed to have a charge air cooler?

 

[mountainguyed67]

I could build on something like this.

 

[mountainguyed67]

Can the transmission handle the increased torque of the turbo?

 

[mountainguyed67]

Will it be interchangeable with the automatic? Crankshafts are the same?
