TECO Electric Motor AETHCF

Change the oil at regular intervals

Determine the time between oil changes based on operating conditions

Use good grade, oxidation-corrosion-inhibited turbine oils

Specify the viscosity of the oil based on bearing type, size, load, speed, ambient temperature, and cooling water

Is the ambient temperature near or below freezing?

Preheat the oil or use special oil if necessary

Ensure oil-metering hole is clear

Clean screens and louvers over inlet air openings

Clean the external fan thoroughly

Clean air-to-air heat exchanger tubes

Rotate the shaft a few revolutions

Bearing protection — tilt-pad bearings

Pour in approximately one cup of oil

Rotate the shaft a few revolutions

Ensure the volume and quality of lubrication oil are in compliance with specifications

Check motion of the oil ring to ensure it is not clamped

Measure the shaft endplay and ensure it is within the specified range of the red groove of the shaft

Is the shaft endplay within the ±0.118 in. (±3mm) range of the drive-end shaft shoulder?

Inspect ratchet pins for deformation

Inspect check valve and stop valve

Verify normal function of valves
