L2 Bearing Modifications
Two Days
#L2a Changing shielded bearings to sealed bearings on stock motors. 48-449T, Agricultural motors as well as all Washguard duty and Wash-Thru motors have sealed bearings as standard. Note: Adding sealed bearings to motors having grease fittings may not make the bearings regreasable. Grease fittings will be removed and plugged.
#L2b Stock motors with shielded or sealed bearings – replace standard bearings with ones having low-temperature lubricant (Beacon #325 or equivalent), with a temperature range of –75°F to +250°F. Standard lubricant has a temperature range of –20°F to +300°F and is considered a high temp lubricant for these motors. Explosion proof motors can only be rated to a –13°F temperature.

#L2c Change bearing grease on cast iron motors with open- type regreaseable bearings. Endbells and bearings are purged and repacked with low-temperature grease (Beacon #325 or equivalent) with a temperature range of -75°F to +250°F or high-temperature grease (Dow Corning DC44M or equivalent) with a temperature range of -40°F to +400°F. Specify grease to be used. Check with LEESON to verify the motor can operate in the temperature range required! LEESON Only.
#L2d Install insulated bearings to protect inverter-driven motors from inverter-sourced shaft voltages. May not be installed on Division 1 or Division 2 hazardous locations. Contact factory for lead time on installing insulated bearings.
