How far should the friction disc be seated inside the drive pulley hub?
On my 129, I had to get new set screws for the disc. It seems that if I push the disc in so that the complete thickness of the disc is inside the hub, the set screws will wind up tightening against the eccentric collar rather than the bearing. Shouldn't it tighten against the bearing? A quick search came across this older thread. I'm going to go with the pictures that show the teeth inside the hub but not all the way in as suggested in the manual. I see there are some sort of springs that are part of the whole pto clutch assy. If there were originally springs on there, they've been gone for decades!!

The hub will only go on till the snap ring inside the hub stops it against the bearing so it can't go on too far unless the internal snap ring is missing ?? I think on that model the bearing is locked flush with the end of the crank ?

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.
