The product was exactly what I needed. Much better, and just a little more expensive, than trying to piece together old, worn parts with a new wheel bearing. Craftsman will indeed sell only the bearing, but it is very hard to install because of a compression spacer and a snap ring (requiring a special tool.)
Through trial and error, I found the proper order to install the new height adjuster, which includes a pre-installed new bearing. (see YouTube video https://www.youtube.com/watch?v=QiT8mlHceWA.)
Disassembly of old adjuster:
- Remove wheel (if you have a new wheel, you won't need this)
- Remove gear by removing C-clip (save them for later)
- Remove Pin, it has a head and only comes out one way (save Pin for later)
Notes: Mark or take note of direction. Pin has pressure from compressed spacer, so it will be difficult to remove. You might try compressing the spacer. This problem is noted in the video.
- Remove plastic cover and washer (save them for later))
- Unscrew old adjuster from lawnmower (2 nuts under mower, save them for later)
Note: One nut is close to the transmission. As you unscrew, you might have to pull the old adjuster out a little to remove this nut.
Assembly
- Install Pin from step 3 above.
Notes: Try to use the same direction as in step 3, but it might not matter. There might be pressure, so it might involve some compression. This problem is noted in the video.
- Install adjuster using nuts from step 5 above.
Note: Start both nuts with new adjuster pulled out a little, then tighten both.
- Install plastic cover (and washer) from step 4 above
- Install gear using C-clip from step 2 above.
- Install wheel
