Frequently Asked Questions

Q: What is the purpose of a caster cap like the 00591-57791-81?

Q: Which Toyota electric lift truck models use this caster cap?
A: This caster cap is designed for specific Toyota electric lift truck caster assemblies. Caster caps vary by caster size and mounting style. Contact our parts team with your truck model and caster configuration to confirm fitment for your equipment.

Q: What material is the 00591-57791-81 made from?
A: The caster cap is manufactured from durable polymer or metal, depending on the caster series. The cap is designed to fit snugly over the caster assembly bearing for reliable protection.

Q: When should this caster cap be replaced?
A: Replace the caster cap if it is cracked, split, or missing. A damaged cap allows water and dirt to reach the bearing, causing rust, corrosion, and accelerated bearing failure. Replacement is recommended immediately upon damage detection.

Q: How should caster caps be maintained?
A: Inspect caster caps monthly during routine equipment maintenance. Ensure caps remain seated and undamaged. Clean the exterior to remove salt, debris, and moisture. Replace if cracks or separation develop to prevent damage to the underlying caster assembly.
