1450 Drive Shaft - Ball Bearing or not?
Hey all,
I am currently in the process of replacing the flex couplers in my 1975 (per the serial number) 1450. On the rear/hydro side of the shaft, I have read that there should be a 5/8" ball bearing. However, there was not one anywhere to be found when I drove out the pins and disassembled everything. Inside the drive shaft side of the hydro flange, there is a bushing that the shaft slides into. The end of the shaft is also flat, such that the ball bearing wouldn't "fit" into the end of the shaft. Pics attached for reference. Is this this updated drive shaft design that doesn't use a ball bearing? I only have 1 flex disc on each end of the shaft, and my understanding was that the later design used 3 discs total. Maybe what I read was incorrect. Am I okay to run without the ball bearing, or should I wait for the bearing I ordered to arrive before reassembly? Thank you!

The ball (#22 in the picture) is used in the gear drive tractors with a clutch to support the driveshaft form being forced rearwards by the clutch action
With a hydro, no need. As for flex discs, one at each end is factory but some folks opt to double them up for more rigidity. Your choice to do if you want it.

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.
