Which statement about the 10-year service milestone for the Type-H is correct?

• A. It requires no action
• B. It requires a complete overhaul
• C. It requires replacing the pendant cable only
• D. It requires inspecting the drive motor

Answer: (B)

When equipment reaches a long service interval, maintenance philosophy shifts toward restoring full performance through a complete overhaul. For the Type-H, the 10-year milestone signals that a thorough reconditioning is needed because wear, lubrication degradation, and aging components accumulate over time. A complete overhaul typically involves disassembling, inspecting all critical mechanical and electrical parts, cleaning, replacing worn items, re-lubricating, realigning, and performing functional tests to ensure safe, reliable operation. This comprehensive service addresses multiple potential wear points rather than just one area. Choosing no action ignores the impact of aging and can lead to hidden faults. Replacing only the pendant cable tackles a single component and misses other wear or degraded parts. Inspecting the drive motor alone covers only one element and still leaves other components that may be worn or out of spec. The complete overhaul is the best choice because it restores the unit to acceptable operating condition and helps prevent unexpected failures.
