Frequently Asked Questions
Q: What is the difference between GWK-PE4000-LW and GWK-PE4000-LW-XL?
A: GWK-PE4000-LW-XL features sealed bearings and 97A durometer polyurethane wheels as a complete assembly, emphasizing durability and minimal maintenance. Standard GWK-PE4000-LW may have different bearing or wheel specifications. Both fit PE 4000 series. If your jack operates in high-moisture or continuous-duty environments, the XL model is preferred for sealed bearing protection.
Q: Can I use GWK-PE4000-LW-XL on Crown PE 3000 or older models?
A: No. This kit is engineered exclusively for Crown PE 4000 Series electric pallet trucks. Axle bore sizes, mounting hole spacing, and frame clearance differ on PE 3000 or earlier models. Installation on non-PE 4000 jacks will result in misalignment and failure. Verify your jack model before ordering.
Q: What do sealed bearings mean, and do I need to lubricate them?
A: Sealed bearings are enclosed in a protective shield or seal, preventing dirt and moisture from entering. They are pre-lubricated at the factory. In normal warehouse use, sealed bearings do not require additional lubrication. In high-moisture environments or after extended heavy use, you may apply a light coat of general-purpose grease around the bearing exterior if you notice stiffness, but this is not routine maintenance.
Q: How do I install the XL kit, and are there any precautions?
A: Installation steps: Lower jack fully and secure with wheel chocks. Remove fasteners from existing wheel assemblies. Pull off old wheels and axles using appropriate tools. Install new axles with sealed bearings into frame mounting points. Install and hand-tighten all fasteners in a cross pattern to prevent binding. Torque to Crown specification (check your manual—typically 35–50 foot-pounds for load wheel fasteners). Spin wheels freely to confirm proper alignment before loading.
Q: What is the expected lifespan of these 97A polyurethane wheels under normal warehouse use?
A: 97A durometer polyurethane wheels typically last 18–36 months in moderate indoor warehouse use (5–8 pallets per day). Lifespan varies with floor condition, load frequency, and storage environment. Smooth, clean concrete extends life. Rough concrete or outdoor exposure reduces lifespan to 6–12 months. Replace proactively when wheels lose shine, show cracks, or become noticeably harder to the touch.
Q: Does this kit come with fasteners, or do I need to purchase them separately?
A: Kit includes all fasteners—steel axles, fastener hardware, and sealed bearings. No additional components are required. Use the hardware supplied with the kit; do not reuse old fasteners from worn wheels, as they may be damaged or out of specification.
