Caster Assembly for Pallet Jacks

Frequently Asked Questions

Q: What is the CR 133109-004-OS and which Crown trucks use it?
A: The CR 133109-004-OS is a direct replacement caster assembly for select Crown electric lift truck models. Fitment depends on your truck model, serial number, and mounting location. Refer to your Crown equipment documentation or contact your Crown dealer to confirm compatibility with your specific truck.

Q: How does the CR 133109-004-OS differ from other Crown caster part numbers like CR 133109-001-OS or CR 133109-002-OS?
A: The CR 133109-004-OS, CR 133109-001-OS, and CR 133109-002-OS are distinct Crown part numbers used on different truck models or mounting positions. Each represents a different caster assembly specification. Do not assume interchangeability between these part numbers without verifying your Crown equipment documentation.

Q: Can the CR 133109-004-OS be cross-referenced with casters from Toyota, Raymond, Yale, or other lift truck manufacturers?
A: The CR 133109-004-OS is a Crown specification part designed for Crown equipment. While Toyota, Raymond, Yale, Hyster, and others produce caster assemblies for their equipment, fitment to Crown trucks is not guaranteed. Verify mounting interface, bearing type, load rating, and overall dimensions before attempting any cross-brand substitution.

Q: What material and bearing type does the CR 133109-004-OS use?
A: The CR 133109-004-OS features high-strength steel construction with sealed roller bearings for durability in material handling service. The sealed bearing design is factory pre-lubricated to minimize routine maintenance requirements. Refer to your Crown parts documentation for exact material composition and bearing specifications.

Q: What is the expected service life of the CR 133109-004-OS?
A: Service life depends on load conditions, floor surface types, duty cycle intensity, and bearing maintenance. The sealed bearing design minimizes lubrication needs. Regular visual inspection for bearing wear, corrosion, or seal damage helps identify replacement timing. Replace the caster assembly if bearing play, noise, or resistance to rotation develops.

Q: Is the CR 133109-004-OS pre-lubricated or does it require initial lubrication?
A: The CR 133109-004-OS comes factory pre-lubricated with sealed roller bearings that require minimal routine maintenance. The sealed design protects against dirt and contaminants, extending bearing life in warehouse and dock environments.
