Frequently Asked Questions
Q: What are the dimensions and bore specifications for the CR 81645-030 wheel assembly?
A: The CR 81645-030 features a nominal 3-inch by 3.25-inch wheel with a 0.75-inch sealed ball bearing bore. The high-strength polymer hub is designed for press-fit installation on Crown electric lift trucks. Verify wheel diameter and bore size match your equipment before ordering.
Q: Which Crown electric lift truck models are compatible with the CR 81645-030?
A: The CR 81645-030 is compatible with Crown electric lift truck models. This wheel assembly replaces CR 81645-025 and supersedes CR 81645-020. If you are unsure of your equipment model or serial range, provide those details to confirm fitment compatibility.
Q: What material is the CR 81645-030 tread made from and how does the 95A durometer rating affect performance?
A: The CR 81645-030 features 95A durometer polyurethane tread bonded to a high-strength polymer hub. A 95A Shore A hardness rating provides balanced abrasion resistance and load-bearing capacity for typical warehouse and manufacturing environments. This compound offers good grip on dry and lightly wet floors.
Q: What are the cross-reference part numbers for the CR 81645-030?
A: The CR 81645-030 supersedes CR 81645-020, replaces CR 81645-025, and is equivalent to CR 81645-035. The part is interchangeable with CR 81645-040 and CR 81645-A. Always confirm bearing size and hub width match your current wheel before substituting part numbers.
Q: How long does the CR 81645-030 wheel typically last before replacement is needed?
A: Wheel lifespan depends on usage intensity, floor surface type, and load weight. Heavy-duty warehouse environments typically see wheel replacement every 12 to 24 months. Inspect for tread wear, flat spots, and bearing play to determine if replacement is needed. A well-maintained wheel assembly with sealed bearings resists contamination better than exposed designs.
