Spread frame repower
 

I have a 1989 CC 1050 spreadframe. Which to my understanding is essentially a white and yellow 582 with a kohler magnum 10hp.

I also have a source for a K341 that I want to use to repower the 1050. I don't know yet if it is a narrow block or a wide block. From another forum I read it doesn't really matter. If it is a narrow block then I could use a cradle from a 1282 or 1204, and if it a wide block ???? I don't know. Has anyone done this swap on a 582? Will it work?

Thanks Matt

I can't speak for fitment, but have you considered the facts that:

1. The Magnum is magneto ignition, the K341 is coil & points.
2. The Magnum has internal voltage regulation, the K341 is external.
3. The Magnum is equipped with a starter, the K341 uses a starter/generator for starting and charging.

All wiring issues.

ironman....the 1650 used k-341 that had a flywheel driven starter and a stator with a rectifier/regulator. The 169 used a starter/generator.

Attached are pics of the k341. Can anyone tell me if this has a flywheel driven started or starter/generator? I believe it to be a flywheel driven 1987 k341. As far as having points or internal/external regulator I don't know. Any help would be appreciated. Also still trying to find out if this repower will work.

The K341S-71309 was an engine built for the WW Grainger Company as an aftermarket replacement. It is a 1987 model with an Electric Starter.

I didn't even think of that. I was assuming a 169's K341. I stand corrected, thank you!

Ironman, you just had a brain fart....you know your stuff!:beer2:

Cadetpuller, that engine will require a great deal of modification to work in a 1050. Also, the crankshaft may be the wrong size for the PTO clutch. Something else too, the oil pan is not one that is used in a typical Cub Cadet.

I'm not worried about the PTO clutch as it will only be used for pulling. Does the K341 share a block with anything that cub cadet did use that I could swap oil pans with?

the block is flanged at the bottom to accommodate a standard oil pan/mounting surface. I suppose you could make something work to mount this engine. the flywheel. however. is not set up to connect a driveshaft.

Thanks for the info. Sounds like something beyond my skill set and budget. I'm just building something for fun, not competition.

I can pick this motor up for $125 and it starts and runs good. I think I might just go ahead and get it.

Sounds like a good price. Have fun with your project and keep us posted! pics of your project are always appreciated.:beerchug:

When you remove that flywheel screen you may find that there are bolt holes in the flywheel to attach some sort of driveshaft coupler.

That would be great!!

A quick google search of the k341 flywheel reveals that it is drilled tapped for driveshaft adapter. Another google search pulls up this adapter.

That engine, K341S-71309 used the KH-47-025-28S Flywheel. The K341 engine had 15 different flywheels. Does the internet search show which one of the 15 is being displayed ??


:bigthink:

47 025 28-S. Would this be the same one the my K341 came with?

A quick check on the CCC parts lookup site will answer that question as well as many others you will surely have.
Avail yourself of this asset and learn your way around on that site & place a shortcut on your desktop.
You will be using it more than once I can guarantee!!

That is what I stated. I question the picture.

So do you plan on spinning that motor over 4000?

No. My plan was to keep it safe around 3800 maybe.

Just curious cause if you were, you would prolly replace that flywheel anyway.

It's always an option.

So I've been thinking about this for a while. What would make a flywheel not set up to connect a drive shaft? Well, today it dawned on me. It's not the flywheel. It's the end of the crankshaft. At least on the K series that I'm familiar with, the crank has an male threaded stub and the drive hub is actually bolted to the crank.

Where as the crank shafts in the engines like those pictured in post #4, similar to my Gravely walk behinds, has no male stub on the crank. Therefor any attempt to attach a drive hub to just the flywheel may be met with some less than desirable results.
