Frequently Asked Questions
Q: What components are in the CR 74657-020-A Load Wheel Assembly?
A: The CR 74657-020-A is a pre-assembled unit containing the load wheel, axle shaft, and sealed bearing components. All internal parts are lubricated and sealed at the factory. This assembly eliminates the need for separate bearing installation and reduces on-site assembly time.
Q: Is the CR 74657-020-A compatible with the same Crown models as the CR 74657-020 wheel?
A: The CR 74657-020-A fits the same Crown lift truck platforms as the CR 74657-020 wheel. However, verify that your truck frame accommodates the full assembly (wheel plus axle length). If your truck has a damaged or non-functional axle, the assembly version is the correct replacement.
Q: How do I maintain the bearing seals on the CR 74657-020-A?
A: The CR 74657-020-A bearings come sealed from the factory and are not field-serviceable. Do not attempt to disassemble or re-lubricate the bearing. If seal damage occurs (indicated by grease leakage or wheel wobble), replace the entire assembly. Seal failure leads to bearing rust and premature failure.
Q: What is the typical service life of the CR 74657-020-A assembly?
A: The CR 74657-020-A assembly typically lasts 2 to 4 years in normal warehouse service. Life extends to 4 to 5 years in light-duty applications with regular cleaning to prevent debris accumulation. Replace when wheel diameter wear exceeds 0.25 inches or bearing noise becomes audible.
Q: Can I replace the wheel portion if the CR 74657-020-A assembly is still good?
A: No. The CR 74657-020-A is a sealed assembly and cannot be disassembled for partial replacement. If the wheel shows wear but the axle and bearing appear sound, you must replace the entire assembly as a unit. Separate wheel and axle components are not available from this assembly SKU.
