Default k241 knock?????

Ok just recently picked up a cub 107 with a k241 kohler I have a knocking sound but here's the problem we pulled the motor and everythingseemed ok no excessivewear no chunks it looked really good as well as the piston does not have any slop or ovaling in the cylinder put it all back together and still knocks but it doesn't get worse or better at throttle changes I removed the clutch for the mower deck because had some people tell me they where notories for making. Knok still no fix what could it be I don't had to rebuild the motor if it doesn't require it "if it ain't broke don't fix it" just at a head scratching point and just plan lost HELP

It could possibly be the front PTO making the knocking noise. My 100 does that and it's the front PTO.

Or it could be the crank bearing, and why I say that is the 241 in my Dad's 102 sounded just like you described and that's what was wrong with ours but that was 15 years ago and I don't remember all the details. Hope that helps!

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.
