Baldor Reliance Electric Motor 9240-SB-OPEN

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 lubricant if necessary

Ensure use of clean, fresh grease from clean containers

Verify grease compatibility if mixing is required

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

Section 3 – Anti-Friction Bearing Removal/Replacement

Ensure equipment connected to the motor shaft cannot cause shaft rotation

Disconnect all electrical power from the motor windings and accessory devices

Replace bearing when worn, oversize, or when TRG/bearing temperature monitoring indicates excessive wear

Remove the bearing using a conventional bearing puller

Protect the shaft center using a spacer block of bass or soft material

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

Identify extreme conditions present

Ensure lubrication procedure follows the 6 Monthly task guidelines

Check relubrication intervals and volumes on the main motor nameplate

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

Is the shaft stationary and motor warm for relubrication?

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

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?

Check air filters for high velocity air speeds

Measure resistance to air flow of a clean filter

Is the resistance to air flow within acceptable limits?

Check static air pressure drop across the filters

Is the static air pressure drop within acceptable limits?

Check if Differential Air Pressure Switch is activated

Are air filters in place and clean?

Condition-based task: clean or replace filters if pressure drop reaches threshold
