Frequently Asked Questions
Q: What equipment is the HY 4077405 load wheel assembly compatible with?
A: The HY 4077405 load wheel assembly is designed for Hyster W40Z and W45Z HD electric pallet trucks. This is an OEM assembly that replaces earlier variants HY 4077404, HY 4077406, HY 4077407, HY 4077451, HY 4077453, HY 4077454, HY 4078160, and HY 4078161. Verify your specific lift truck model and serial range before ordering to confirm compatibility.
Q: What materials and components are included in the HY 4077405 assembly?
A: This load wheel assembly features a polyurethane 95A wheel, stainless steel lube bearings, integrated string guards, steel riser bracket, and precision mounting hardware. The stainless steel bearings provide corrosion resistance and extended service life in wet or cold storage environments. The polyurethane compound offers durable tread contact and load distribution across the wheel assembly.
Q: Is HY 4077405 equivalent to or interchangeable with HY 4077405-XL?
A: HY 4077405-XL is an equivalent part number for the same load wheel assembly. Both SKUs refer to the same assembly with lube bearings, string guards, and riser. Use HY 4077405 or HY 4077405-XL interchangeably when ordering replacement assemblies for your Hyster W40Z or W45Z HD truck.
Q: What cross-reference part numbers exist for HY 4077405?
A: HY 4077405 supersedes part numbers HY 4077404, HY 4077406, HY 4077407, HY 4077451, HY 4077453, HY 4077453-XG, HY 4077454, HY 4078160, and HY 4078161. The equivalent part number is HY 4077405-XL. If you have older documentation referencing the superseded numbers, the current OEM assembly is HY 4077405.
Q: What is the durometer hardness of the HY 4077405 polyurethane wheel?
A: The HY 4077405 features a polyurethane wheel with 95A durometer hardness. This hardness rating provides a balance of traction and wear resistance for standard material handling applications. The 95A compound resists abrasion on concrete and warehouse floors while maintaining grip in normal operating conditions.
Q: How does stainless steel bearing construction affect the service life of this assembly?
A: The stainless steel lube bearings in the HY 4077405 resist corrosion and extend service life compared to standard steel bearings, especially in damp or salt-exposed environments. Stainless steel bearings maintain lubrication film longer and reduce bearing degradation, supporting longer intervals between replacements. Bearing condition should be inspected during routine maintenance for noise, binding, or play.
