Frequently Asked Questions
Q: Is GWK-PE4000-XL-LW the same as GWK-PE4000-LW-XL, and which SKU should I use?
A: GWK-PE4000-XL-LW and GWK-PE4000-LW-XL appear to be the same kit with SKU designation variation. The manufacturer part number is GWK-PE4000-LW-XL. Use GWK-PE4000-LW-XL as the primary part number for ordering to ensure accuracy and avoid confusion with distributors.
Q: What specific features qualify this kit for industrial material-handling use?
A: Kit includes high-performance polyurethane wheels (Shore A 97 hardness), precision steel axles, sealed ball bearings, and Grade 8 mounting fasteners. These components are engineered for continuous-duty industrial environments—frequent loading cycles, hard concrete floors, and extended daily operation. Grade 8 fasteners resist vibration loosening and corrosion.
Q: Can this kit be installed on any Crown electric pallet jack, or only PE 4000 Series?
A: PE 4000 Series only. This kit is not compatible with Crown PE 3000, PE 3500, or non-electric Crown jacks. Axle bore diameter and frame mounting geometry are specific to the PE 4000 platform. Verify your jack model on the nameplate before purchasing. Cross-model installation will damage the frame and create a safety hazard.
Q: What is the difference between 97A durometer wheels and softer polyurethane options?
A: 97A (Shore A hardness) is the standard specification for indoor warehouse concrete. This hardness provides good durability and floor grip without marking. Softer wheels (90–95A) provide more grip and floor protection but wear faster in high-use environments. Harder wheels (98A+) reduce wear but may cause floor scuffing on polished concrete. For typical warehouse use, 97A is optimal.
Q: How do I diagnose if the PE 4000 frame or axles are bent, versus just needing new wheels?
A: Symptoms of bent frame or axles: persistent pulling to one side even after new wheels are installed, wheels do not rotate freely in their mounting holes, or audible clicking when the jack moves. Test: Lift the jack frame slightly off the ground and spin wheels by hand. If one wheel is noticeably harder to turn or catches, the axle may be bent. Bent axles or frames cannot be corrected by wheel replacement and must be replaced or welded by a technician.
Q: What maintenance schedule should I follow to maximize wheel and bearing life?
A: Weekly: Inspect wheels for debris or damage and clean if needed. Monthly: Spin wheels by hand to check for resistance or stiffness—sealed bearings should rotate freely. Quarterly: Check fastener tightness with a wrench (vibration can loosen Grade 8 fasteners over time). Replace wheels when they lose gloss finish, show cracks, or when you notice jack handling degradation. Sealed bearings typically do not need lubrication; do not force grease into sealed bearing assemblies.
