Frequently Asked Questions
Q: What Caterpillar equipment does the CT 1009309 caster wheel assembly fit?
A: The CT 1009309 is a precision caster wheel assembly for Caterpillar NPP 60 electric pallet trucks. Alternate model designation is NPP60. Verify your equipment serial range matches before ordering.
Q: What does the 95A polyurethane tread specification mean?
A: 95A refers to the Shore hardness of the polyurethane tread compound. This hardness level provides durability and grip for standard material handling environments on typical warehouse floors.
Q: What load capacity does the CT 1009309 support?
A: The CT 1009309 is rated. This rating applies when the wheel is part of a complete assembly on the NPP 60 truck.
Q: What bearing type is used in this caster wheel assembly?
A: The CT 1009309 features sealed ball bearings for maintenance-free operation. Sealed design protects against dust and debris intrusion in warehouse and outdoor environments.
Q: Is the CT 1009309 interchangeable with other part numbers?
A: The CT 1009309 is interchangeable with CT 1009309-SG. It supersedes earlier Cat 1009309 versions. Contact us if you need cross-references to equivalent casters from other manufacturers.
Q: What are the electrogalvanized washers for in this assembly?
A: Electrogalvanized washers provide corrosion resistance and prevent loosening of fasteners. They enhance durability in wet storage and outdoor material handling applications.
Q: How should this caster wheel be stored between uses?
A: Store in a clean, dry environment away from direct sunlight and extreme temperature fluctuations. Keep away from solvents and oils that may degrade the polyurethane tread. Keep wheels in an upright position to avoid flat-spotting the tread.
Q: What maintenance does the CT 1009309 require?
A: Periodically inspect sealed bearings and fasteners for looseness. Check the polyurethane tread for wear or damage. Clean wheels with mild soap and water; do not use harsh solvents. Electrogalvanized washers require no additional maintenance.
