Frequently Asked Questions
Q: What are the exact wheel dimensions on the 4077400 load wheel assembly?
A: The 4077400 wheel measures 3.34 inches in diameter by 4.33 inches in width. These dimensions are critical for mounting compatibility. Verify these measurements against your equipment mounting area before ordering to ensure proper fit and clearance.
Q: What bearing material does the 4077400 use, and why is stainless steel sealed construction important?
A: The 4077400 uses stainless steel sealed bearing construction. Stainless steel resists corrosion in humid warehouse and dock environments. Sealed construction prevents moisture and contaminants from entering the bearing cavity, which extends operational life and reduces bearing failure risk.
Q: What does 95A durometer hardness mean for the 4077400 polyurethane wheel?
A: 95A Shore A durometer indicates a medium-hard polyurethane formulation. This hardness provides balanced traction and wear resistance for standard material handling loads without excessive floor marking. The Durarun polyurethane compound is engineered for typical pallet jack and lift truck duty.
Q: Does the 4077400 include the riser component and what other hardware is included?
A: Yes, the 4077400 is a complete assembly that includes the wheel, riser component, mounting axles, integrated string guards, lubrication fittings, and fastening hardware. All necessary parts for mounting are included; no additional components are required.
Q: Is there a related assembly kit cross-reference for the 4077400?
A: A related assembly kit 310700-231-KIT exists for similar applications. Contact us to confirm whether this kit is appropriate as a substitute or upgrade for your specific Hyster electric pallet jack model and serial range.
Q: What is the expected lifespan of the 4077400 wheel in normal warehouse operation?
A: Lifespan depends on duty cycle, load weight, floor surface conditions, and maintenance frequency. The sealed bearings and Durarun polyurethane compound are designed for extended service life. Monitor wheel wear and bearing noise during regular equipment inspections to determine replacement timing.
