GWK-MPW065E-LW-XL

Frequently Asked Questions

Q: What makes GWK-MPW065E-LW-XL different from the standard GWK-MPW065E-LW kit?
A: GWK-MPW065E-LW-XL is the upgraded variant with 97A shore A durometer polyurethane wheels versus the standard kits 95A compound. The XL designation indicates extended-life performance for high-duty warehouse applications running 6-8 hours daily. Both kits use identical 3.25 x 4.50-inch wheel dimensions and fit Yale MPW065E electric pallet jacks on the same axle mounting points. Standard 95A wheels last 16-20 months; the 97A XL compound extends life to 28-32 months under continuous operation.

Q: Is GWK-MPW065E-LW-XL cross-compatible with Hyster or Crown Equipment parts?
A: GWK-MPW065E-LW-XL is Yale-specific and does not have direct Hyster equivalents. It is cross-compatible with Crown Equipment part number 310700-207-KIT for the A894 platform, but the Crown part is only available in 95A durometer. If you require a 97A equivalent from Crown, Crown does not offer an XL variant; you must use the GWK-MPW065E-LW-XL (Yale OEM) or revert to Crown standard 95A wheels.

Q: What is the rated load capacity, wheel size, and grease maintenance schedule for GWK-MPW065E-LW-XL?
A: Load capacity is 5000 lbs at a 24-inch load center. Wheel dimensions are 3.25 inches diameter by 4.5 inches width. The kit includes integrated grease fittings with steel axle and pre-lubricated ball bearings. Grease the bearings every 250 operating hours or monthly using NLGI Grade 2 lithium-based grease; pump 2-3 strokes per fitting until grease purges from the bearing seals. Over-greasing damages the seals. The 97A XL compound supports longer service intervals; wheels last 28-32 months under high-duty conditions.

Q: What are the installation steps and torque specifications for GWK-MPW065E-LW-XL?
A: Installation requires: 0.625-inch socket, rubber mallet, 10-ton hydraulic jack, and 6000-lbs-rated jack stands. Lift the truck 12 inches. Remove the cotter pin and hex axle nut. Using the rubber mallet, gently tap the wheel assembly toward you to unseat the bearing cartridge. Slide the assembly off. Inspect the axle shaft for scoring or corrosion; replace if necessary. Slide the new GWK-MPW065E-LW-XL assembly onto the axle with the bearing cartridge facing outward. Hand-tighten the hex nut, then torque to 40 ft-lbs using a calibrated torque wrench. Install a new cotter pin through the axle hole and nut slot. Allow 2 hours for bearing seals to cure before operation. Installation takes 12-15 minutes per wheel.

Q: What diagnostic signs indicate GWK-MPW065E-LW-XL wheels or bearings are failing and need replacement?
A: Replace the wheel kit if you observe: audible squealing that persists after greasing, grinding noises during loaded movement, visible flat-spotting or loss of wheel roundness, chunks or delamination missing from the polyurethane tread, asymmetrical wear between left and right wheels, truck pulling or drifting left or right without steering correction, or play when manually spinning the wheels by hand. Squealing after maintenance typically indicates bearing seal failure requiring replacement. Grinding indicates internal bearing damage. Any symptom requires immediate replacement.

Q: Can I upgrade from standard 95A wheels to GWK-MPW065E-LW-XL (97A) on an existing truck?
A: Yes. You can upgrade from the standard GWK-MPW065E-LW (95A) to GWK-MPW065E-LW-XL (97A) on any Yale MPW065E truck. The 97A XL wheels are dimensionally identical and use the same 0.625-inch axle bore mounting. The upgrade provides 30-40 percent longer wheel life and improved durability for high-duty applications. Remove the old 95A kit following standard wheel replacement procedures, then install the 97A XL kit using identical torque and cotter pin procedures. The upgrade is tool-free and requires no axle modifications.
