Frequently Asked Questions
Q: What components are included in the 74657-020-A load wheel assembly?
A: The 74657-020-A is a pre-assembled complete unit containing the load wheel, axle shaft, and sealed bearing components. All internal parts are factory-lubricated and sealed at manufacture. This integrated design eliminates the need for separate bearing installation and reduces on-site assembly time compared to individual wheel components.
Q: What Crown equipment is the 74657-020-A compatible with?
A: The 74657-020-A is designed as a direct replacement for Crown lift truck platforms and electric pallet jacks. Verify compatibility with your specific Crown model before ordering. Contact Crown Equipment or your authorized parts distributor with your equipment serial number or model designation to confirm fitment.
Q: What maintenance does the bearing seal require?
A: The 74657-020-A bearings arrive sealed from the factory and are not field-serviceable. Do not attempt to disassemble or re-lubricate the bearing. If you observe grease leakage or wheel wobble, these indicate seal failure. Replace the entire assembly immediately, as bearing rust and premature failure will follow seal compromise.
Q: How long does the 74657-020-A assembly last in service?
A: The 74657-020-A typically lasts 2 to 4 years in normal warehouse service conditions. In light-duty applications with regular cleaning to prevent debris accumulation, service life may extend to 4 to 5 years. Replace the assembly when bearing noise becomes audible.
Q: Can the wheel be replaced separately if the 74657-020-A assembly is otherwise functional?
A: No. The 74657-020-A is a permanently sealed assembly and cannot be disassembled for partial component 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 configuration.
Q: How should I store the 74657-020-A when not in use?
A: Store the 74657-020-A in a clean, dry environment protected from moisture and extreme temperature fluctuations. Keep the assembly indoors or under cover to prevent corrosion and dust accumulation on bearing seals. Store horizontally to minimize stress on bearing components during extended periods of non-use.
