Frequently Asked Questions
Q: What is the difference between CL 277940 and CL 277940-A?
A: The CL 277940 is the load wheel component alone. The CL 277940-A is the complete assembly, which includes the wheel plus integrated mechanical components such as bearings and axle hardware. The assembly is a ready-to-install, matched unit requiring no additional components.
Q: Should I order the wheel alone or the complete assembly?
A: If your axle, bearings, and mounting hardware are in good condition, the wheel alone may be sufficient. If bearings are worn or you are performing complete drivetrain maintenance, the CL 277940-A assembly provides all components as a matched unit. Consult your service manual to confirm which solution applies to your situation.
Q: What is included in the CL 277940-A assembly?
A: The CL 277940-A includes the load wheel plus integrated mechanical components. For a detailed bill of materials and exact component list, contact Clark Material Handling support or your authorized parts distributor.
Q: Is the CL 277940-A compatible with multiple Clark models?
A: The CL 277940-A is a Clark factory-spec assembly. Compatibility is model and generation specific. Always verify your exact truck model, serial number range, and axle configuration against Clark documentation before ordering.
Q: How often do load wheels need replacement?
A: Load wheel lifespan depends on operating hours, floor conditions, load weight, and driver behavior. Typical wear life ranges from 18 to 36 months in heavy-duty warehouse service. Regular inspection for flat spots, cracks, or bearing noise will indicate when replacement is needed.
Q: What maintenance does the CL 277940-A assembly require?
A: Periodically inspect bearings for noise, play, or resistance during manual wheel rotation. Keep the assembly clean and free from debris. Lubricate bearing points as specified in your equipment service manual. Replace the assembly if bearings become rough, noisy, or the wheel shows cracks or permanent flat spots.
Q: How should I store the CL 277940-A if not installing immediately?
A: Store the assembly in a clean, dry location protected from moisture, direct sunlight, and temperature extremes. Keep the wheel off the ground to prevent flat-spotting. Store upright or on a mounting rack if available.
