Baldor Reliance Electric Motor 8040-AF-LV

Section 3 – Horizontal Shaft Motors

Maintain proper lubricant level

Check that constant level oilers have oil in them

Check that cap on oiler is screwed on tightly

Section 3 – Sleeve Bearings (Oil Lubricated)

Select appropriate lubricating oil

De-energize the motor by opening the manual disconnect switches

Remove drain plug and drain oil

Flush out the housing by filling with fresh oil and drain again

Replace plug and fill through filler cap until oil level is at proper level indicated on sight gauge

Section 1 – Storage (less than 6 months) – Horizontal Motors with Sleeve Bearings

Fill the bearing oil reservoir to the indicated level with the proper lubrication oil

Pour 4 to 6 ounces of oil onto the bearing liner before rotating the shaft

Rotate the shaft 10-15 revolutions to redistribute the lubricant

Ensure the following conditions are met before rotating the shaft

Verify that Duty Master motors are filled with oil containing a rust inhibitor at the factory

Confirm that a thin film of oil remains on vital parts for rust protection

Section 3 – Checking Insulation Resistance

Check the insulation resistance of the stator winding with an insulation resistance meter

Record the insulation resistance value

Investigate and take corrective action if there is a significant change in insulation resistance

Calculate the minimum insulation resistance (RM) using the formula RM = KV + 1

Compare the insulation resistance reading with the calculated RM

If insulation resistance is less than RM, dry out the windings

Bake in an oven at a temperature not to exceed 90°C until insulation resistance remains constant

Section 3 – Anti-Friction Bearing (Grease Lubricated)

Ensure motor is under standard conditions (8 hrs/day, normal or light loading, clean ambient air at 40°C max)

Check motor nameplate for relubrication intervals and volumes

Refer to motor nameplate for recommended lubricant

Select alternate lubricants if necessary

Ensure use of clean, fresh grease from clean containers

Verify grease compatibility if mixing different greases

Ensure grease is free of dirt to avoid damage to motor bearings
