Frequently Asked Questions
Q: Which Crown pallet jack models use the CR 77086 load wheel?
A: The CR 77086 is engineered for Crown PW Series walkie electric pallet jacks and Crown PE 3000 Series pallet trucks. It features the Durarun 95A polyurethane formula and external bearing design compatible with these model series. Confirm your specific equipment serial range and fork configuration before ordering to ensure fitment.
Q: What material properties does the CR 77086 polyurethane offer?
A: The CR 77086 uses Durarun 95A polyurethane formula with 95 Shore A durometer hardness. This compound provides durability and load-bearing capacity in fork wheel applications. The polyurethane formula is engineered to resist flat spotting, coning, and uneven wear across varied industrial floor conditions including concrete and asphalt.
Q: What is the external bearing design on the CR 77086?
A: The CR 77086 features an external bearing design integrated into the assembly, along with a fastener retention system and integrated axle assembly. This configuration allows for straightforward bearing inspection and replacement without disassembling other fork truck components. The external design supports the repetitive lifting and lowering cycles of walkie pallet jack operations.
Q: Are there alternative part number formats for the CR 77086?
A: The CR 77086 is also referenced in alternative format as CR077086. Both formats refer to the identical Durarun 95A polyurethane load wheel assembly with external bearing design. Order by either the standard format CR 77086 or the alternative CR077086 to ensure you receive the correct assembly.
Q: When should the CR 77086 be replaced?
A: Replace the CR 77086 when polyurethane tread depth is significantly worn, flat spotting or coning appears on load surfaces, or external bearings show side-to-side play and rotational resistance. Regular inspection of wheel condition and bearing function helps identify wear patterns early. Operating on damaged wheels reduces load stability and increases equipment wear.
