Additional information

This caster axle cap, part number 731-08637A, installs on the end of the caster axle to help keep axle-mounted components in place while protecting the axle end from debris and moisture. A properly seated cap helps maintain smooth caster operation and reduces wear.

If the caster wheel feels loose, components slide on the axle, or the axle end is exposed, the cap may be cracked, worn, or missing. Poor retention can also lead to increased wear on nearby parts.

Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Press the axle cap fully onto the axle end until it seats securely and does not pull off during normal movement.
