Reinstall Caster Wheels and Lubricate

What happens here

Install the assembled caster wheel with new bearings back onto the mower deck. First, insert the through-bolt, ensuring it passes cleanly through the bearings. Next, install a new washer and tighten the new nut with a wrench. Do not overtighten, as this can damage the bearings. Lubricate the grease fitting on the caster wheel with a grease gun until grease begins to seep out. Repeat this process for the remaining caster wheel.

Goal: Attach the repaired caster wheels and ensure smooth operation.
