1. Went to your site to look at which parts had been there before they broke off and fell somewhere in the yard.
2. Ordered the parts and waited them to arrive.
3. Unscrewed the bolt-shoulder from the cutting height mechanism (a.k.a. arm pivot), allowing me to remove the wheel.
4. Slipped the new bolt that had been cracked (screw-shoulder) into the arm pivot.
5. Re-attached the wheel.
6. Slip the spacer-wheel over the screw-shoulder.
7. Slip the screw-shoulder through the hole in the chassis.
8. Place the washer-flat on the screw-shoulder
9. Screw on the nut to the screw-shoulder.
