Crown OEM Durarun 95A Polyurethane Load Wheel Assembly

Frequently Asked Questions

Q: What is the CR 81645-A and what equipment does it fit?
A: The CR 81645-A is a direct replacement polyurethane load wheel assembly engineered for electric lift truck applications. It features a 95A Shore A hardness rating and is compatible with select Crown lift truck models. The lightweight assembly reduces overall equipment mass while maintaining full load-bearing capacity.

Q: What are the cross-reference part numbers for CR 81645-A?
A: The CR 81645-A is equivalent to CR81645-010, CR81645010, and 81645010.

Q: What does 95A Shore A hardness mean?
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 and load-bearing efficiency on both dry and lightly damp surfaces.

Q: Does the lightweight design affect wheel performance or load capacity?
A: No. The lightweight design reduces overall lift truck mass, improving acceleration and energy efficiency on electric models. Load capacity is not compromised because the 95A polyurethane tread and wheel geometry are optimized for standard warehouse duty cycles.

Q: What maintenance does the CR 81645-A require?
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 do I know if CR 81645-A is the correct replacement for my equipment?
A: Verify that CR 81645-A is listed in your Crown lift truck service manual or parts diagram. If you are uncertain, contact Crown Equipment support or a qualified forklift parts distributor with your lift truck model number.
