Frequently Asked Questions
Q: What are the key specifications for the CT A000000842-ST steer wheel?
A: The CT A000000842-ST features a nylon thermoplastic hub and polyurethane tread rated at Shore A 95 hardness. This assembly is engineered for continuous high-duty cycle manual pallet jack applications.
Q: What equipment is the CT A000000842-ST compatible with?
A: The CT A000000842-ST is compatible with Caterpillar HPT series manual pallet jacks and functions as a direct replacement for Clark CJ55 and related Clark manual pallet jack models (H-1043, H-1193, H-1366).
Q: What are the cross-reference part numbers for the CT A000000842-ST?
A: The CT A000000842-ST is a direct replacement for Clark CL 1808270-HD. This part number cross-references across Caterpillar and Clark equipment platforms.
Q: Why does the CT A000000842-ST use a nylon hub instead of aluminum or cast metal?
A: Nylon thermoplastic hub construction provides superior impact resistance and damping characteristics ideal for the repetitive impacts encountered in manual pallet jack operation. This material choice extends wheel service life in demanding warehouse and material handling environments.
Q: What does Shore A 95 hardness mean for the polyurethane tread?
A: Shore A 95 indicates a firm, wear-resistant polyurethane formulation engineered for sustained use on warehouse floors. This hardness rating provides good load-bearing capability while resisting surface scuffing and degradation.
Q: Can I use the CT A000000842-ST on older manual pallet jack models?
A: The CT A000000842-ST is compatible with multiple Caterpillar and Clark manual pallet jack generations. Verify the wheel mounting diameter, bolt pattern, and axle specifications match your equipment before ordering to ensure proper fit.
Q: How long does the CT A000000842-ST typically last?
A: Service life depends on floor conditions, load weights, and frequency of use. The nylon hub and Shore A 95 polyurethane tread are rated for continuous duty operation. Inspect periodically for wear and replace when tread depth reduces or if the wheel shows structural damage.
