Steering failure on my Cub Cadet, and general clean up.

4. When parts were received I removed the Flange Lock Nut,​ 7/​16-20 with the 7/16 socket and ratchet, pried off the Steering Pinion Gear, with a flat head screwdriver.
5. The worn part still wasn't accessible so I had to take loose the drag links (left and right hand) by taking loose the locking flanged nuts. using socket and ratchet set.
6. Had to remove the Steering Support Bracket (6 self tapping screws): tools 5/16 socket, ratchet, 6" extension.
7. Pulled bracket down off of the steering shaft, washer and worn hex flanged bearing now accessible. with the steering support bracket down I tighten or replaced any loose or worn parts. Checked the hex cutout in the support bracket for ware, was acceptable. Centered the steering wheel.
8. Placed the hex flanged bearing in placed, placed washer on steering shaft, hex bearing, bracket, another washer, pushing the steering bracket in place on the steering shaft, replaced the 6 self tapping screws, center steering gear on steering plate ( used stubby Phillip screwdriver ), replaced the pinion steering gear and self locking nut.
9. Align front wheels, Adjust and reinstall the drag links (left and right hand).
10. Ensure everything was tight, let lawn tractor down off jack, checked the steering, worked great. Installed mower deck.

Drive tensioner pulley spun its' bearing apart
Remove battery, seat and deck to expose drive pulley tensioner assembly
Release tensioner spring from right side of box frame.
Unbolt Flange nut on the bottom of the tensioner pulley to remove the pulley.
Insert new pulley with the long side of the center collar facing down and the short v-belt in the pulley grooves of all three pulley assemblies.
Insert screw downward through tensioner pulley and mounting bracket. Secure with flange nut.
Re-attach tensioner spring from tensioner bracket to right box frame.
Replace deck, seat and battery

Please note, this was just the beginning of my journey. All because the lawn mowers variable drive slipped so badly it would not move sometimes.

After replacing the above-described tensioner I discovered I still had problems and that the belts were bad. I ended up going back and replacing them. This improved but did not completely correct the problem and I then I discovered the variable drive pulley assembly was also bad.

So a word of advice. If you get into this variable drive you may want to do the whole thing. Tensioner, variable drive pulley, the bearings for the variable drive pulley and the belts. By the time any one of these items goes bad there is a very good chance that they are all worn out. You will likely save yourself the trouble of repeatedly tearing it apart if you do the whole thing.

Steering column gear stripped, front axles worn our bushings
Taking everything off to get to the gear assembly including moving gas tank, top of dash, dropping the front of the deck, removing front tires...After fighting with the phillips screw at the bottom of steering shaft for an hour finally had to use torch to heat it then use the 1/2" impact to break it loose...If you follow your exploded parts list and not lose any parts this repair is just time consuming but is not that hard...
