Frequently Asked Questions
Q: Is GWK-WR6000-LW compatible with other Caterpillar pallet jack models?
A: No. GWK-WR6000-LW is engineered exclusively for Caterpillar WR6000 pallet jacks. It will not fit other Caterpillar models or competitor brands. Always verify your truck model plate matches WR6000 before ordering. Using on incompatible equipment voids safety and may cause operational failure.
Q: What is ultra-polymer Durarun and why is it used?
A: Ultra-polymer (Ultra-Poly) Durarun is a proprietary elastomer compound rated 95A Shore hardness. It provides exceptional resistance to cuts, abrasion, and chemical contamination compared to standard polyurethane. Durarun wheels maintain traction longer in harsh industrial environments (dock areas, contaminated floors, outdoor use) and resist hardening from prolonged use.
Q: Are bearings and axles pre-installed in this kit?
A: Yes. GWK-WR6000-LW comes with pre-installed bearings and axles. The entire wheel assembly is pre-assembled and ready for bolt-on installation. You do not need to disassemble, replace bearings, or source additional hardware. Installation requires only a socket set and takes 25-40 minutes.
Q: What environmental conditions is this kit rated for?
A: The 95A Durarun wheels perform well in demanding industrial environments including dock areas, outdoor ramps, contaminated warehouse floors, and facilities with oil or grease exposure. The Ultra-Poly compound resists softening from heat and degradation from chemicals better than standard wheels. Do not expose wheels to solvents or temperatures above 130 degrees Fahrenheit.
Q: What maintenance is required to maximize wheel lifespan?
A: Inspect wheels every 30 days for cracks, flat spots, or hardening. Keep the truck floor area clean to prevent debris from embedding in wheel surfaces. Lubricate axle bearings every 6 months during heavy use (monthly in outdoor/contaminated environments). Durarun wheels typically last 3-6 years depending on use intensity and floor conditions.
Q: How do I know when this wheel kit needs replacement?
A: Replace the kit when you observe visible cracks, chunks missing from wheels, flat spotting that does not resolve with rotation, wheel wobble during operation, or squeaking/grinding noises from bearings. These indicate wheel or bearing failure. Do not delay replacement as worn wheels compromise truck control and can damage axles if bearings fail completely.
