Frequently Asked Questions
Q: What is the CR 81645-A wheel assembly and what equipment does it fit?
A: The CR 81645-A is a Crown OEM Durarun 95A polyurethane load wheel assembly engineered for electric lift truck applications. It is compatible with selected Crown equipment models and features a 95A Shore A hardness rating. This wheel is lightweight while maintaining high load-bearing capacity.
Q: What are the cross-reference part numbers for the CR 81645-A?
A: The CR 81645-A is equivalent to and interchangeable with CR81645-010, CR81645010, and 81645010. It is also equivalent to CR 81645-030, CR 81645-035, and CR 81645-040. Before ordering, confirm that bore diameter, hub width, and wheel diameter match your current assembly.
Q: What does the 95A Shore A hardness rating mean for performance and durability?
A: The 95A Shore A durometer rating indicates a hard polyurethane compound that resists abrasion and cutting under sustained loading. This hardness provides good wear life on typical warehouse concrete floors while maintaining adequate grip. A 95A compound balances tread life with load-bearing efficiency on both dry and lightly damp surfaces.
Q: Is the CR 81645-A wheel assembly lightweight and does that affect performance?
A: Yes, the CR 81645-A is designed as a lightweight assembly. Lighter wheels reduce overall lift truck mass, improving acceleration and energy efficiency on electric models. Lightweight design does not compromise load capacity because the 95A polyurethane tread and wheel geometry are optimized for typical warehouse duty cycles.
Q: What maintenance is needed to keep the CR 81645-A wheel in good condition?
A: Inspect the wheel quarterly for tread wear, flat spots, and bearing condition. Check for side-to-side movement and listen for bearing noise during operation. Sealed bearings do not require manual lubrication. Replace the wheel if tread is worn smooth, if the wheel wobbles, or if bearings sound rough or grinding.
Q: How does the CR 81645-A compare in price and durability to equivalent part numbers?
A: The CR 81645-A is an OEM Crown part offering direct fitment and warranty coverage. Equivalent part numbers such as CR 81645-030, CR 81645-035, and CR 81645-040 provide the same 95A polyurethane durability and load capacity. All are interchangeable if bore diameter and hub width match. Confirm your specific equipment before ordering.
