Frequently Asked Questions
Q: What are the dimensions and material specifications for the CR 77084-3-A load wheel?
A: The CR 77084-3-A features a 3.25 inch outside diameter, 2.00 inch tread width, and 2.047 inch bore. The tread is constructed from Durarun 95A polyurethane (Shore A hardness), and the core is steel. This wheel assembly includes factory-matched ball bearings.
Q: Which Crown equipment is the CR 77084-3-A compatible with?
A: The CR 77084-3-A is designed for Crown PE 3000 and PW series electric lift trucks and pallet jacks. Verify that your specific model and serial range fall within these product families before ordering.
Q: What cross-reference and equivalent part numbers are available for the CR 77084-3-A?
A: Cross-reference part numbers include CR77084, 77084, Crown 77084, CR077084, CR077084-3, CR077084-10, and CR77084-30-A. Use these references when cross-checking with OEM documentation or legacy part lists.
Q: What is the durometer rating of the polyurethane tread, and how does it affect performance?
A: The Durarun polyurethane tread has a Shore A durometer of 95A (with some applications rated 93A). This hardness rating provides wear resistance and load-bearing capacity suitable for standard warehouse and light manufacturing environments. Higher durometer means longer tread life but reduced cushioning on rough floors.
Q: How do I determine if the CR 77084-3-A needs replacement?
A: Replace the wheel when tread wear reduces the outside diameter below 3 inches, the tread shows flat spots or visible damage, the wheel does not rotate freely, or the bearing develops play or noise. These symptoms indicate loss of load capacity and handling performance.
