Frequently Asked Questions
Q: What are the dimensions and material of the CR 77084-40 load wheel?
A: The CR 77084-40 is a 3 1/4 x 3 1/4 inch HL (high load) polyurethane load wheel with a 95A Shore Durarun polyurethane tread and precision industrial polymer core. The wheel includes a factory-matched ball bearing for smooth rotation.
Q: Which Crown equipment models use the CR 77084-40?
A: The CR 77084-40 is compatible with select Crown electric pallet trucks and walkie models. The 95A Shore hardness makes this wheel suitable for heavy-duty warehouse and industrial applications. Confirm your specific model is listed in Crown compatibility tables.
Q: What cross-reference part numbers apply to the CR 77084-40?
A: Cross-reference part numbers include CR77084, 77084, and Crown 77084. Use these when searching legacy parts systems or verifying OEM part compatibility.
Q: Why is the 95A Shore hardness important for this load wheel?
A: The 95A Shore polyurethane provides optimal balance between load capacity and wear resistance. This durometer is engineered for sustained heavy-duty operation on standard concrete and asphalt floors. It resists chunking and maintains dimensional stability under continuous loading.
Q: What are the failure indicators that require CR 77084-40 replacement?
A: Replace the wheel if you observe significant diameter loss from wear, flat spots on the tread, cracks or chunks in the polyurethane, or if the bearing no longer rotates freely. A failed load wheel reduces truck maneuverability and increases motor strain.
