Default 782 vibration after hearing pop noise.
While plowing snow last winter, I heard a bang noise and then started to feel an unusual vibration through the frame and steering wheel of my 782 which is a red IH model. The tractor starts up and moves around like normal but still has the vibration. My first thought was to check the drive shaft and cloth connecting disks, But they looked normal. My next area I thought would check was the flywheel to see if any magnets came loose, so I pulled the motor and now have it hanging from my engine hoist. Does anyone have any Ideas on what I should be looking at.

If your flywheel came apart I don't think it would be able to keep running.
Is it a KT17? Was it still running on both cylinders?

Yes it is a KT 17 series ll. Yes it is running on both cylinders. The magnets are glued to the back side of the flywheel and can break loose but would they jam in there and wedge between the block ? My next step was to pull the flywheel and with winter comming possibly a tear down on the motor. I have never had this motor out. Can you still find parts for this motor

Having a 782 myself, I would re-examine the Flex Disc's, and the Drive Shaft Couplers, to see if something is out of round.

Remove drive shaft and start engine to see if it still vibrates

The KT17 regardless of series one or two will break connecting rods. Sometimes they will not damage the block or jugs. Pull the heads and see if both pistons move when turning the crank.

You can accomplish the same thing with removing the Spark Plugs and insert a dowel rod into the chamber, to see if it goes Up/Down.

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.
