Amazon Maintenance Technician Preventive Maintenance & Lubrication

Question 1

What is the main goal of a Preventive Maintenance (PM) program in an Amazon fulfillment center?

Accepted Answer

Detect and correct potential failures before unplanned downtime occurs

Answer

Preventive maintenance is designed to identify and address wear or degradation before it causes unexpected equipment failure and production stoppage.

Question 2

Which lubrication method is BEST suited for hard-to-reach bearings on continuously running conveyor systems?

Accepted Answer

Auto-lubricator (single-point or multi-point) that delivers grease during operation

Answer

Automatic lubricators deliver precise grease amounts to inaccessible bearings during operation, eliminating under- or over-lubrication and the need for shutdowns.

Question 3

What does the NLGI grade number indicate on a grease specification label?

Accepted Answer

The grease consistency or thickness

Answer

NLGI grades (000 to 6) classify grease consistency; higher numbers indicate stiffer grease, with NLGI 2 being the most common general-purpose grade.

Question 4

Over-greasing a bearing can cause which of the following problems?

Accepted Answer

Bearing overheating due to churning and increased friction

Answer

Excess grease creates churning resistance that generates heat, elevating bearing temperature and potentially causing premature failure.

Question 5

What information should be recorded when completing a PM work order in Amazon's CMMS?

Accepted Answer

Equipment ID, technician ID, tasks performed, parts used, condition notes, and completion time

Answer

Complete CMMS records enable failure trend analysis, parts forecasting, and compliance auditing, requiring all relevant job details to be captured.
