Frequently Asked Questions
Q: Is GWK-W45ZHD-LW compatible with Yale MPE045VG equipment?
A: GWK-W45ZHD-LW is designed for Hyster W45ZHD with Yale MPE045VG listed as equivalent application. Cross-compatibility requires matching axle diameter, bearing bore, and hub mounting specifications. Before ordering for Yale equipment, verify axle pin size is 0.5625 inch and mounting hub bore matches standard W45ZHD specification. Contact manufacturer with your Yale serial number to confirm compatibility. Do not assume fit based on equipment class alone.
Q: What wheel durometer options are available and how do I choose between 95A and 97A?
A: GWK-W45ZHD-LW standard configuration features 95A durometer polyurethane. Alternative 97A durometer configuration is available as upgrade. Choose 95A for standard duty up to 6 hours daily with balanced grip and wear characteristics. Select 97A heavy-duty variant if equipment operates continuous shifts, over 6 hours daily, or on rough concrete surfaces. The 97A wheels provide 20-30 percent longer service life but slightly reduced vibration damping compared to 95A.
Q: What is the wheel diameter and width, and does this kit fit W45Z models?
A: Wheel dimensions are 3.3 inches diameter by 4.3 inches width. This configuration is specific to W45ZHD heavy-duty designation and is not interchangeable with standard W45Z wheels. W45ZHD requires the larger bearing bore and different axle specification. Do not attempt to fit W45ZHD wheels to W45Z equipment as axle and mounting hub specifications differ. Always verify your exact model designation before ordering.
Q: What maintenance items are included and what about string guard protection?
A: Kit includes sealed bearing assemblies, lubricated axle system, string guard protection components, and complete mounting hardware. String guards prevent rope, chains, and strapping materials from wrapping around wheel axles during operation. Inspect string guards monthly for cracks or separation from wheel hub. Replace guards if damaged as they are critical safety components. Keep guards free of debris and wrapped material by cleaning weekly in high-utilization environments.
Q: How does Durarun polyurethane compare to standard polyurethane compounds?
A: Durarun polyurethane formulation provides low rolling resistance with extended wear characteristics and temperature stability. This compound resists hardening in cold environments and maintains grip across wider temperature range than standard polyurethane. Durarun wheels show lower floor marking tendency on light-colored concrete. Service life typically extends 15-20 percent longer than standard formulations under equivalent duty cycles. Cost premium is 10-15 percent over standard wheels but justified by extended intervals.
Q: What is the installation procedure and any compatibility considerations?
A: Installation follows standard wheel kit replacement procedure. Raise jack fully, lower forks, and remove fasteners from existing wheel assembly. Use bearing puller tool to extract old wheels and axle assembly from frame. Press new wheel assemblies onto hardened steel axles using controlled-speed bearing press. Reinstall in jack frame and secure with OEM-specification fasteners and cotter pins. String guards must align properly with wheel hub before operation. Verify wheel rotation is smooth through complete load cycle test before returning equipment to service.
