WALMART MAINTENANCE Preventive Maintenance 3

Question 1

When performing preventive maintenance on a hydraulic pallet jack, which component should be inspected for cracks or deformation first?

Accepted Answer

The forks and frame

Answer

The forks and frame are structural load-bearing components — cracks or bends directly affect safe operation and must be checked first.

Question 2

A PM checklist item calls for 'inspecting belt tension' on a conveyor. What symptom indicates the belt is too loose?

Accepted Answer

Belt slips or squeals under load

Answer

A loose belt slips and squeals under load because it cannot transfer torque efficiently from the drive pulley.

Question 3

Walmart's preventive maintenance intervals are primarily based on which factor?

Accepted Answer

Manufacturer recommendations and actual usage hours

Answer

PM intervals should follow manufacturer specifications combined with actual usage hours to ensure timely service regardless of calendar time.

Question 4

What is the correct action when a preventive maintenance task reveals a minor oil leak on a piece of equipment?

Accepted Answer

Tag the equipment out of service and report to the supervisor

Answer

Any confirmed leak requires the equipment to be taken out of service and reported so a repair work order can be generated before further use.

Question 5

Which lubrication practice is most likely to cause damage during preventive maintenance?

Accepted Answer

Over-greasing sealed bearings

Answer

Over-greasing sealed bearings can rupture the seal, pushing lubricant into motor windings or causing the bearing to overheat.
