Frequently Asked Questions
Q: Which pallet truck models are compatible with the HY 4613510-A caster wheel assembly?
A: The HY 4613510-A is engineered for Hyster W60Z, W80Z, B60Z, and B80Z electric walkie pallet truck models. These models share a common mounting configuration and bearing cavity design. The part is a direct replacement for original Hyster equipment. If your truck model does not appear in this list, verify compatibility before ordering by checking your equipment manual or contacting us with your specific model number.
Q: What is the wheel diameter of the HY 4613510-A, and does it fit in the same frame as other load wheels?
A: The HY 4613510-A features a polyurethane wheel. The structural steel frame is integrated into the assembly for rigidity.
Q: What role does the patented poly spring block play in the HY 4613510-A assembly?
A: The patented poly spring block integrated into the HY 4613510-A provides shock absorption when the pallet truck traverses uneven warehouse floors, ramps, and door thresholds. This spring mechanism reduces impact loads transferred to the bearing and frame, which extends bearing life and reduces vibration-related wear. The spring block is sealed and maintenance-free.
Q: What polyurethane hardness does the HY 4613510-A use, and is it suitable for wet floors?
A: The HY 4613510-A uses 90A durometer polyurethane. At 90A, this compound is softer than 95A standards, providing better wet floor traction and floor grip under normal loading. The trade-off is that 90A polyurethane wears faster than harder compounds. In wet storage or cold environments, the 90A formulation is preferable. In dry warehouse conditions, harder wheels (95A+) may last longer.
Q: What aftermarket and factory-equivalent part numbers cross-reference to the HY 4613510-A?
A: The HY 4613510-A cross-references to HY 4613510-XL, HY4613510, and manufacturer part number 4613510. Aftermarket equivalents include TVH SYWHEEL1-THO and Superior brand parts SU240, SU398, SU436, and SU444. When ordering a direct replacement, use the exact part number HY 4613510-A to ensure you receive the correct wheel diameter and spring block configuration for your pallet truck model.
Q: How long does the HY 4613510-A caster wheel typically last in a warehouse environment?
A: Under typical warehouse conditions with daily operation (10-12 hours per day), the HY 4613510-A generally lasts 12-20 months. The 90A polyurethane compound wears faster than harder alternatives, so lifespan depends on floor type, load cycles, and usage intensity. Wet or oily floors reduce lifespan. Monitor wheel tread thickness and replace when worn to factory specifications to maintain proper load wheel geometry and bearing alignment.
Q: Can the HY 4613510-A be stored outdoors, and what conditions should I avoid?
A: Store the HY 4613510-A in a cool, dry indoor location. Avoid prolonged exposure to direct sunlight, extreme heat above 140°F, freezing temperatures below -20°F, or corrosive chemicals. Polyurethane compounds degrade when exposed to UV light and ozone. Keep the assembly dry and store on a flat surface. Store spare wheels in their original packaging to prevent dust accumulation and UV degradation.
