Frequently Asked Questions
Q: What are the key specifications of the 073961-XL-A load wheel assembly?
A: The 073961-XL-A features a polyurethane wheel. It includes integrated shoulder bearings and is manufactured with 97A Shore durometer (XL designation compound). This assembly is compatible with Crown PR Series pallet trucks.
Q: Is the 073961-XL-A wheel suitable for freezer and cold storage environments?
A: Yes. The 073961-XL-A is specifically rated for freezer environments, wet conditions, and metal debris exposure. The 97A durometer compound maintains hardness in cold temperatures where softer compounds become tacky or lose grip. The XL-designation polyurethane provides enhanced traction on wet and icy surfaces common in cold storage warehouse applications.
Q: What are the cross-reference part numbers for the 073961-XL-A?
A: The 073961-XL-A carries alternate designations: 073961, 73961, and generic part number CR 73961-A. The part number CR 073961-XL-A is the primary identifier for the original equipment compatible assembly. When ordering replacement parts, reference the exact part number to ensure you receive the XL-compound variant.
Q: How does the integrated shoulder bearing design affect maintenance requirements?
A: Integrated shoulder bearings are sealed bearing assemblies that do not require field lubrication or service. This design reduces maintenance frequency compared to separate bearing installations. When bearings begin to deteriorate, the entire wheel assembly must be replaced. Listen for increased grinding, squeaking, or resistance to rotation as indicators that replacement is needed.
Q: What load capacity should I verify before using the 073961-XL-A wheels?
A: Verify that your Crown PR Series pallet truck is not rated above 5000 lb capacity and that the wheel bore matches the specification on your equipment spindle. Exceeding rated capacity accelerates bearing wear and polyurethane compound degradation.
Q: How does the 6-inch diameter compare to standard Crown load wheel sizes?
A: The diameter is larger than standard wheels, providing better floor clearance and improved stability on uneven warehouse floors or door thresholds. The larger diameter reduces rolling resistance and polyurethane wear on smooth concrete but may have slightly slower response in tight-turn maneuvers. Verify wheel bore and axle compatibility before replacing smaller wheels with the 073961-XL-A.
Q: What should I inspect during regular maintenance of the 073961-XL-A wheel assembly?
A: Inspect the polyurethane wheel surface for cracks, chunks, or uneven wear patterns. Check for lateral play or wobbling that indicates bearing deterioration. Verify the bore opening is not cracked or deformed. Clean metal debris from the wheel surface and bearing seals regularly. Replace the entire assembly if bearing play exceeds normal tolerances or if polyurethane damage compromises load capacity.
