Started putting things back togather on the 122 today. Now the question is, or problem is with the locking collar and clutch bearing. The service maneal says to lock the bearing with the collar and to the direction of crankshaft rotation. I assume that the "lock" is a cam type lock as I can see no other way to lock the two togather. As you may be able to see from pics, the bearing and collar both have a cam look to them, but will not lock togather. there is a lot of slop when fitted togather. I'm not sure if they are even suppossed to lock togather that way, it may be that they are just wore that way. I am using the same bearing and collar that came off it. I dont know what was holding them on before unless it was just age and corrossion as I used a 3 jaw puller to take the bearing off. Also, does the locking collar set screw just tighten down into the keyway slot? Now for the clutch itself. It says to push the clutch ass'ly on until flush with snap ring, there was not a snap ring there when dissassembled or any indication that one was ever there. What do the 3set screws in the clutch ass'ly tighten down onto, the clutch bearing? If so , they hardly catch the edge of it, maybe the snapring would move it out to where it would tighten onto more of it? Any and all help is appriciated, thanks agian.

The eccentric bore of the locking collar won't lock unless the whole thing is assembled onto a shaft. Try to get the setscrew for the collar somewhere other than in the keyway in the end of the crank; it probably isn't long enough to go all the way down there. The snap ring is inside the clutch; you can see it in the picture you posted. The clutch is on far enough when that snap ring bottoms out against the bearing.

Thanks Matt, I think I understand now. What about the three set screws in the clutch, what do they tighten down agianst. Also, do I run another set screw down on top of them to lock them in, there where only the three in there, and they where different lenghts, one had a sharp point and the other two where flat ended? I was going to use blue locktite. Will give it another try.

They should grab slightly behind the PTO bearing to hold it on. You need two setscrews in each hole- the pointy ones go in first, then the shorter, blunt ones go in over those. No need for loc-tite.

That might explain what caused the problem in the first place. Improper set screws/placement. I sprayed the set screws with WD-40, then a coat of never seize.

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.
