Frequently Asked Questions
Q: What Crown equipment models does the CR 77086-001-A fit?
A: This tandem poly load wheel assembly is designed for Crown PE, PW, PC, and PR series electric pallet jacks and walk-behind trucks. Verify your specific equipment model and serial range with Crown technical documentation to confirm compatibility.
Q: What material and hardness rating does this wheel assembly feature?
A: The CR 77086-001-A uses Durarun 95A polyurethane compound with a 95A Shore A hardness rating. This durometer rating provides the right balance between load capacity and floor protection in warehouse and manufacturing operations.
Q: What is independent wheel rotation and why does it matter?
A: Independent wheel rotation means each wheel in the tandem assembly spins separately on its own bearing. This design reduces axle stress, improves maneuverability during turning, extends bearing life, and decreases floor surface wear in tight warehouse spaces.
Q: Does this wheel assembly replace older part numbers?
A: Yes, the CR 77086-001-A is a direct replacement for CR77086-A and 77086-A. The newer part number has compatible bore and diameter specifications with the same Crown equipment compatibility.
Q: How does the 3.25-inch diameter perform on different floor surfaces?
A: Durarun 95A polyurethane wheel performs well on standard concrete warehouse floors, outdoor surfaces, and sealed floor areas. The material minimizes floor marking while providing durability for heavy-duty material handling and frequent use cycles.
Q: Should I store these wheels in any special conditions?
A: Store wheel assemblies in a cool, dry location away from direct sunlight and extreme heat, as prolonged exposure can degrade polyurethane compounds. Keep wheels clean and dry before storage to maintain bearing performance and extend assembly life.
