Caster Cap

Frequently Asked Questions

Q: What is the purpose of the 00591-37801-81 caster cap?
A: This caster cap is a protective cover that fits over the top of the caster assembly. It protects the caster bearing and internal components from dirt, moisture, and debris while containing lubricant within the bearing housing.

Q: Which Toyota lift truck models use this caster cap?
A: This caster cap is designed for Toyota electric pallet jacks and light-duty lift trucks. Confirm your specific model and serial range before ordering to ensure correct fitment, as various Toyota models may use different caster assemblies.

Q: Can this caster cap fit other brands besides Toyota?
A: This is a Toyota direct equipment part. While some dimensions may align with Crown, Raymond, or similar equipment casters, do not assume cross-compatibility. Verify the exact caster assembly type and mounting interface with your equipment specifications before ordering.

Q: What material is the caster cap made from and how long does it last?
A: The caster cap is typically injection-molded plastic or stamped metal designed to withstand material handling environments. In normal service conditions, a caster cap lasts 3 to 7 years. Cracked, loose, or missing caps should be replaced immediately to prevent water and contaminant ingress into the bearing.

Q: When should a caster cap be replaced?
A: Caster caps deteriorate from impact, UV exposure, thermal cycling, and normal wear. Loss of the cap allows moisture to enter the bearing assembly, accelerating rust and lubricant degradation. Replace damaged caps immediately to extend caster and wheel assembly life.
