What is the purpose of conducting an oil analysis (drain sample) during PM service on gearboxes?
Answer: To detect metal particles, water contamination, and viscosity changes indicating internal wear or contamination
Oil analysis identifies wear metals, contaminants, and fluid degradation, providing an early warning of gearbox internal problems without disassembly.
What does a PM 'A-check' typically include compared to a 'C-check' on Amazon material handling equipment?
Answer: A-checks are frequent basic inspections; C-checks are periodic comprehensive overhauls covering more components
Tiered PM schedules use A-checks for frequent basic tasks and C-checks (or higher) for deeper, less frequent comprehensive maintenance covering wear items and alignments.
Why should lubrication points on powered equipment be lubricated while the machine is STOPPED and locked out?
Answer: To prevent technician injury from moving parts and ensure safe access to all lubrication points
LOTO procedures must be followed during lubrication to protect technicians from entanglement or crush injuries caused by rotating or moving machinery.
What is the correct storage practice for lubricants at an Amazon facility to maintain quality?
Answer: Store in a clean, cool, dry area; keep containers sealed and clearly labeled with type and date received
Proper storage in a cool, dry, labeled environment prevents contamination, moisture ingress, and lubricant degradation that can damage equipment.
A PM task card calls for replacing V-belts on a blower motor. What additional check must be done before installing new belts?
Answer: Inspect sheave grooves for wear and verify correct belt tension after installation using a tension gauge or deflection method
Worn sheave grooves cause rapid belt wear, and correct tension is critical — over-tension overloads bearings while under-tension causes slipping and premature failure.
What is 5S as it applies to a maintenance shop in an Amazon fulfillment center?
Answer: A workplace organization methodology: Sort, Set in order, Shine, Standardize, Sustain
5S is a lean workplace organization system that creates clean, organized, and standardized work environments to improve safety, efficiency, and quality.
