Frequently Asked Questions
Q: What equipment models does the YL 524239786 load wheel assembly fit?
A: The YL 524239786 is a complete load wheel and riser assembly designed for Yale MPB 040 E, MPW 045 E, and MPB 040 AC electric pallet trucks. Cross-reference equivalents include 310700-231-KIT, GWK-MPB040AC-LW, and GWK-MPB045VG-LW-XL. Always verify your truck model and serial range match before ordering to ensure proper fitment.
Q: What are the wheel dimensions and load rating for the YL 524239786?
A: The YL 524239786 features a 3.25-inch diameter load wheel with 4.50-inch width. The polyurethane wheel is rated for 4500 lbs static load per wheel, meaning the assembly supports 4500 lbs on that single wheel when the truck is stationary. Do not exceed this load rating.
Q: What material is the wheel made from and how does it perform in different environments?
A: The YL 524239786 features a high-durometer polyurethane wheel mounted on a zinc-plated steel riser. Polyurethane provides excellent durability on both dry and slightly damp floors. The zinc plating protects the steel riser from corrosion. In cold storage or wet environments, verify that high-durometer polyurethane is suitable for your specific temperature and floor conditions.
Q: Does the YL 524239786 include bearings and hardware?
A: Yes. The assembly includes precision deep groove ball bearings, an axle, and Grade 8 mounting hardware. All components are pre-assembled as a complete unit ready for use on compatible trucks.
Q: What is the typical lifespan of the YL 524239786 wheel assembly?
A: Polyurethane wheel lifespan depends on usage intensity, floor conditions, and load consistency. In typical warehouse applications with mixed loading, a load wheel assembly normally lasts 2-4 years. Wheels in high-temperature or wet environments may wear faster. Regular inspection for flat spots, cracks, or bearing noise will indicate when replacement is needed.
Q: Are there alternative load wheel options if the YL 524239786 does not suit my application?
A: Yes. Several interchange equivalents exist, including 310700-231-KIT and GWK-MPB040AC-LW. Consult compatibility cross-reference tables to confirm which alternative assemblies match your truck model and application requirements such as floor type or temperature range.
