Okay
The parts worked but when looking at the mower deck diagram it didnt show that I need the locking flange nut so I didnt order. Trying to find one in local stores but havent found it yet. So that would be my only complaint.

Tools Used

1. Removed the temporary fix.
2. Lowered deck onto wooden shims on the left side set to the same height as the right side.
3. Removed the pin in the linkage to make it easier to line up deck and parts.
4. Installed parts, tightened into place, replace linkage pin.
5. Checked deck height at lowest, idle and highest levels to ensure it was correct.
6. Cleaned up tools and tested mower.
This was easily done in the driveway with basic tools. I would recommend checking all nuts and bolts when you do your spring maintenance and oil changes throughout the year.

Lined up the deck adjustment bracket with slots for gear up with another bracket behind it, put bolt through the adjustment gear into two holes that were lined up, put on a nut to tighten into, the correct new nut didn't come with the gear, bolt and washer so I improvised with one after I called customer service and they told me a nut wasn't available for it, didn't make sense but I made it work, I suggest checking it often or putting loctite on the bolt threads so the gear doesn't rattle off again.
