Frequently Asked Questions
Q: Does GWK-WR6000-LW-XL fit other Caterpillar pallet jack models?
A: No. GWK-WR6000-LW-XL is engineered exclusively for Caterpillar WR6000 electric pallet jacks. Do not attempt to install on other models as the axle bore diameter, bearing seat, and fastener patterns are model-specific. Check your jack nameplate to verify WR6000 before ordering.
Q: What is the difference between 97A and lower durometer wheels?
A: 97A Shore durometer rating means these polyurethane wheels are harder and more abrasion-resistant than softer compounds like 70D or 80A. Use 97A for rough concrete, outdoor surfaces, and extended run times. Lower durometers (70D) grip better on smooth floors but wear faster on industrial surfaces. The WR6000-LW-XL 97A is rated for heavy-duty material handling with extended load cycles.
Q: Can I replace just one wheel assembly instead of the complete kit?
A: Not recommended. GWK-WR6000-LW-XL is sold as a complete dual-wheel assembly kit with matched durometer, pre-installed sealed bearings, and hardened steel axles. Installing a single wheel creates uneven load distribution and accelerates bearing wear on the remaining old wheel. Always replace all wheels as a set for balanced performance and safety.
Q: What tools do I need to install GWK-WR6000-LW-XL?
A: You will need a socket set, breaker bar or ratchet wrench, bearing grease, lint-free cloth, and a work stand to lift the jack safely. Do not work under a raised jack without proper support. All fasteners and axles are included. Installation typically takes 30 to 45 minutes per wheel assembly. Consult the WR6000 service manual for torque specifications on axle fasteners.
Q: How long will the sealed bearings last before replacement?
A: Sealed ball bearings in GWK-WR6000-LW-XL are rated for 2000 to 3000 hours of continuous operation under rated load capacity. Runtime depends on floor surface, load weight, and maintenance. If you hear grinding noise or wheels do not roll freely, bearings require replacement. Many operators get 12 to 18 months from sealed bearings before noise develops. Replace bearings as an assembly; do not attempt to repack.
Q: What is the maximum load rating for wheels on WR6000?
A: Total pallet jack load capacity is determined by the frame and hydraulic system, not the wheels alone. GWK-WR6000-LW-XL wheels are engineered to support the WR6000 rated capacity without exceeding bearing or polyurethane stress limits. Do not exceed the jack nameplate load rating. Overloading causes accelerated wheel wear, bearing failure, and unsafe operation. Check your jack documentation for exact capacity.
