Default K181 Flywheel Question,, For My 800

I feel the engine in my 800 sounds "iffy",,,,
and I kinda want to replace it,,

I have a K181 that was used less than 20 hours, then parked in an open shed,,,

The engine was on an oddball Gravely clone tractor,, I bought two of them brand new,, and never used them beyond the 20 hours this one was run.

My question is,, do I have to swap flywheels, or will the driveshaft pulley simply connect to the big nut?



All the Cubs I have played with, I do not think I ever disassembled this end of the engine before.

The shaft on the other end of the engine is 1",,

is 1" the "standard" size for the electric PTO to connect to??

Never having owned or worked an 800, I can't answer about flywheel differences (just guessing, I would think they are the same).

I think the bigger question would be, is the 20 hour engine block drilled for the electric PTO mounting bolts?

And yes, you are correct in thinking that 1" is correct for the PTO end of the shaft.

the drive hub has a dowell pin that goes into a hole in the flywheel . I don't think the hole is there in your pic.

OOPS!!,, sorry, I zoomed in too far,, yes, it has a starter,,,



I ordered a new carb, the ignition has spark when I crank the engine with the starter,,

It has the large starter, but, I have the small one,, I will swap starters when I get it running,,,

I think the flywheel has the needed hole that holds the offset pin,,

The engine had at least 20 mud dauber nests in the cooling fins,, and a regular paper wasp nest under the fan shroud.

Yes, the old carb has a mud dauber nest in the fuel inlet!!

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
