Frequently Asked Questions
Q: What are the dimensions of the CR 77084-040 poly load wheel?
A: The CR 77084-040 is a 3.25-inch diameter by 3.25-inch width load wheel. This compact size is engineered for high-lift electric truck applications where space constraints and precision load positioning are critical. Verify the wheel bore diameter matches your equipment axle before ordering.
Q: Is the CR 77084-040 a direct replacement for the Crown 77084 wheel?
A: Yes, the CR 77084-040 directly replaces the Crown 77084 load wheel. Cross-reference numbers include CR77084-040, CR77084040, and 77084040. If your equipment currently uses the 77084 model, this part number is the current direct replacement and is fully compatible.
Q: What polyurethane compound and durometer is used in the CR 77084-040?
A: The CR 77084-040 uses precision-molded industrial-grade polyurethane (95A durometer) in a high-performance formulation. This hardness rating provides excellent load-carrying capacity and resistance to floor abrasion in high-lift truck applications, with durability suitable for standard warehouse environments.
Q: What Crown equipment models use the CR 77084-040?
A: The CR 77084-040 is designed for Crown PW and PR Rider series electric lift trucks equipped with poly load wheel assemblies in high-lift configurations. Confirm your equipment model number on the nameplate before ordering, as different Crown models may use different wheel sizes in different positions.
Q: How should I store and maintain this polyurethane wheel?
A: Store the CR 77084-040 in a cool, dry location away from direct sunlight and extreme heat, which can degrade polyurethane. Inspect wheels regularly for uneven wear, cracks, or flat spots. Clean with mild soap and water as needed. Replace wheels when tread wear becomes visible or when wheels show signs of damage or reduced performance.
