Nut 583343001

Placed the adjustment lever on its post.
Placed the lock nut on the post.

push the nut on...

I replaced the plastic sleeve bushing and the bearing that supports the self propelled rear axle.
1. Removed the back wheels.
2. Used snap ring pliers to remove the gears on the axles.
3. Unbolted the handle bar brackets from the mower deck.
4. Placed the brackets in a vice and removed the nut assembly that holds the bearing/plastic sleeve.
5. Purchased all new parts.
6. Used a dead blow hammer to insert new plastic sleeves into the nut assembly that also holds the bearing.
7. The plastic sleeve is very tight and will have some plastic shavings come off as it is seated.
8. Used a socket to seat the new bearing into the nut assembly. 9. Tightened the new nut assembly back into the handle bar bracket.
10. Bolted the brackets back on the deck.
11. Snap ringed the gear back to the axle.
12. Tightened the wheels back on.
I also replaced the axle bolts, the seat spacer between the inside of the wheel and dust cover and the rear wheels. However that was overkill. Just required the plastic sleeve bushing and bearing.

1- Screwed in parts
2- removed old parts and replaced

I just had to install all of the parts I ordered. Super easy really.

Took off broken knob and replaced with new knob, only using a pair of pliers.
