Frequently Asked Questions
Q: What are the dimensions of the 78409 load wheel?
A: The 78409 is designed for Big Joe Millennium Series electric pallet jacks to provide optimal load distribution and maneuverability in warehouse environments.
Q: What material is the 78409 wheel tread made from?
A: The tread is constructed from 92A durometer polyurethane, which provides excellent wear resistance and load-bearing capacity on concrete and smooth warehouse floors. This hardness rating ensures the wheel maintains its shape under full load and sustained operation.
Q: Is the 78409 a direct replacement for Big Joe Millennium Series equipment?
A: Yes, the 78409 is manufactured as a factory-spec replacement wheel for Big Joe Millennium Series electric pallet trucks. Verify your equipment model and serial number match before ordering to confirm compatibility.
Q: What are all the part numbers for this wheel?
A: The primary part number is 78409. The manufacturer part number is BJ 78409. Cross-reference numbers include BJ78409, BJ78409-A, 078409, and BJ078409. These all refer to the same load wheel assembly.
Q: How long does a polyurethane load wheel typically last?
A: Polyurethane wheels typically provide 2 to 5 years of service depending on operating conditions, floor surface, load weight, and usage frequency. The precision steel hub and powder coat finish support extended durability. Inspect wheels periodically for flat spots, cracking, or uneven wear.
Q: How should I maintain the 78409 load wheel assembly?
A: Regularly inspect the wheel tread for damage, flat spots, or cracking. Clean debris and buildup from the wheel surface. Monitor the hub bearings for smooth rotation and listen for unusual noise. Replace the wheel if the tread becomes severely worn or uneven, or if the hub shows signs of damage or corrosion.
Q: Can the 78409 be used on other pallet jack brands?
A: The wheel may be compatible with other brands having similar hub specifications, but we recommend verifying hub bore diameter, axle fit, and load rating match your specific equipment before use. Consult your equipment manual or contact the manufacturer for compatibility confirmation.
Q: What finish is applied to the steel hub?
A: The precision steel hub is powder coated to provide corrosion resistance and durability in humid warehouse and industrial environments. This protective finish helps extend the service life of the wheel assembly.
