Baldor Reliance Electric Motor 10840-AF-OPEN

Section 3 – Anti-Friction Bearing (Grease Lubricated) – Severe Conditions

Verify applicable motor conditions

Describe the operating conditions

Ensure lubrication procedure follows the 6 Monthly task guidelines

Check relubrication intervals and volumes on the main motor nameplate

Is the shaft stationary and motor warm?

Stay clear of rotating parts and electrical circuits if lubrication is done with motor running

Locate the grease inlet, clean the area, and replace the pipe plug with a grease fitting if necessary

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

Rotate the shaft 10-15 revolutions to redistribute the lubricant

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

Section 3 – Checking Insulation Resistance

Check conditions for insulation resistance testing

Measure the insulation resistance of the stator winding

Enter the rating machine potential (KV) in kilo volts

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

Is the insulation resistance less than the calculated RM?

Record the insulation resistance reading

Is there a significant change in insulation resistance compared to previous readings?

Describe any corrective actions taken if there is a significant change in insulation resistance

Section 3 – Sleeve Bearings (Oil Lubricated) – Severe and Extreme Conditions

Is the oil discolored or contaminated?

Follow the oil change procedure as per the standard Sleeve Bearing Oil Change task

Select oil viscosity and quality as per Table 3-4 and Section 3 Sleeve Bearings (Oil Lubricated)

De-energize the motor by opening the manual disconnect switches

Remove drain plug and drain oil

Does the oil appear to be contaminated?

Section 3 – Sleeve Bearings (Oil Lubricated)

Select lubricating oil based on conditions

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 if oil is contaminated

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

Tighten caps and plugs, fill constant level oiler if provided
