Default Engine swap 129

I broke the rod this winter plowing snow on my original k301A. It was my grandfather's tractor that he gave me some time ago and has been a workhorse for me. Iv'e been fighting with the fly wheel. It won't come off with a wheel puller and hammer to the shaft. No one around here works on old IH cubs.

Meanwhile, spring is here and I need to get the tractor going again. So I purchased a k341A from Ray W. in PA. It has good compression. It is not a starter generator set up like the k301A was. So, trying to figure out the wiring. Anyone have any experience on transplanting the k341A into a wide frame cub with out a starter generator? No more use for an F wire? Voltage regulator bypassed? Lastly, does the PTO from the k301A work on a k341A or should I purchase another and install? I was under the understanding that the 341 would bolt right in, but wiring differences are throwing me for a loop.

The pictures and videos on youtube for this kind of thing are scarce. Thanks in advance for the help.

Assuming the K341 came from a Quietline,
have you looked at and compared the two wire diagrams in the Tech section?

Right off the get-go ignition switches are different, then you can rewire from there.

Shrouding and muffler are different on Quietlines, what's you plan there?
That might interfere with manual PTO, but I'm guessing.

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.
