TECO Electric Motor AEGHPE

Bearing protection — tilt-pad bearings

Remove the pipe plug from the bearing cap located above the tilt-bearing shell

Pour in approximately one cup of oil

Rotate the shaft a few revolutions

Is the storage period longer than usual?

Remove the accumulated oil from the housing

2.6 Bearing protection — sleeve bearings

Ensure the following conditions are met for sleeve bearings

Rotate the motor shaft several revolutions to keep bearing journals well oiled and prevent rusting

Did the shaft come to rest in a different position than its original?

While rotating, push the shaft to both extremes of the endplay

Clean the interior of the bearing housing and flush with clean oil or kerosene

Wipe clean the bearing halves and shaft journal with a lint-free cloth soaked in clean oil

Inspect all parts for nicks, scratches, etc., in contact surfaces

Remove imperfections using appropriate methods (stoning, scraping, filing) and clean thoroughly

Is the floating labyrinth seal in good condition? (No cracks or chips)

Ensure bottom half seal holes are positioned at the bottom toward the inside of the bearing

Apply a bead of Curil-T around the seal half O.D.'s on both sides adjacent to the garter spring groove

Place the bottom seal half on top of the shaft and roll it into position, then install the top half and insert the garter spring

Regular examination — Periodical change of oil

Drain the oil reservoir of self-lubricated bearings

Is the motor high speed (3600 rpm) or is there severe oil discoloration or contamination?

Flush the reservoir with kerosene if contamination is present

Thoroughly drain the reservoir of the flushing material

Refill the reservoir to the center of oil sight glass with rust and oxidation inhibited turbine grade oil

Refer to the outline and lubrication nameplate for the correct viscosity and record it here

Change the oil at regular intervals

Determine the interval for oil changes based on operating conditions

Is the ambient temperature near or below freezing?

Use the lubrication oil stipulated by the lubrication nameplate, if attached
