126 stuck PTO bearing and collar
Hello, I'm wondering if anyone can help me with the stuck collar and PTO bearing. One youtube said to tap the collar counter-clockwise but a post said to tap it clock-wise. Neither are working. I've tried PB Blaster and WD40 but it's on tight. I'm about to resort to the angle grinder and a cutoff wheel. Any better ideas?
Thanks

It is supposed to be tightened by tapping it counter-clockwise, same direction as the rotation, looking at the PTO. So, theoretically, it should be loosened by tapping it clockwise. With about a 3/16 drift, and a 16 oz or better hammer. Give it a good whack.
Caveat is that it is probably just as often tightened the other direction, so if it doesn't come loose CW, give it another whack CCW. Good luck! And welcome to OCC! Oh, the reason it is tightened CCW is because with CCW rotation, force on the PTO is CW (resistance to rotation) which would tend to tighten the bearing inside the eccentric lock collar.

Sawdustdad,
Isn't it normally tightening in use, in the direction resisting rotation? So wouldn't that imply tap in the direction of rotation (against the way it would be experiencing force while in use) to loosen? Or am I mixed up? Regards, Andy

Did you remove the set screw holding the collar to the shaft? Andy, the centrifugal force is thightening the collar to the bearing, not the shaft.

In reality, it seems to work most of the time regardless of which way it is tightened on installation as I've found them both ways. It does have a set screw as well. Every time I've removed one, it's a guess which way to drive it to loosen it. I try CW first, then if that doesn't work, CCW.

The lock collar doesn't move real far maybe qtr turn or so, couple wacks and should be loose, if the collar is loose the brg should slide off fairly easy, if it's rusted fast soak it good with p-oil and get a puller on it but make sure the collar is unlocked and clean up crankshaft before sliding off so there are no burrs or raised metal for it to get stuck on !

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.
