Maintenance During Storage
DANGER
Hazardous voltage.
Can cause death, severe injury, or
property damage.
Follow all safety rules.
Sleeve Bearings
Per Chart 1, the motor shaft should be manually rotated by hand at about 30 rpm for 15 seconds or if power is
available, the motor can be electrically bumped for 5 seconds;
Chart 1
STORAGE ENVIRONMENT Shaft Rotation Frequency
INDOOR – WHOLLY CONTROLLED ATMOSPHERE Every two (2) months
INDOOR – PARTIALLY CONTROLLED ATMOSPHERE Once per month
OUTDOOR – INLAND DRY CLIMATE Once per month
OUTDOOR – INLAND HUMID CLIMATE Once per week
OUTDOOR – SALTY AND INDUSTRIAL ATMOSPHERE Once per week
Tilting Pad Bearings
INDOOR STORAGE: Do not turn the shaft on motors with this type of bearing unless an external flood
lubrication system is connected and in operation. If this system is not available, do not run the motor, but
every three months, disassemble the motor for access to the bearings and coat the bearings and the shaft
journal area with a rust-inhibiting turbine oil of the proper viscosity.
OUTDOOR STORAGE: The motor should not be stored outdoors.
Oil Lubricated Antifriction and Kingsbury Type Bearings
Every three (3) months, 3000-3600 RPM vertical motors with anti-friction bearings should be run for two minutes
to recoat the oil-lubricated bearings. If the motor cannot be run, it must be partially disassembled to reach the
bearings. Manually cover the bearing with a fresh coat of oil. The oil itself need not be renewed.
On 1800 rpm and slower speed vertical motors, the shaft should be rotated by hand every two (2) months. Turn it
by hand at about 30 rpm for 15 seconds or if power is available, the motor can be electrically bumped for 5
seconds.
Grease Lubricated Anti-Friction Bearings
Per Chart 2, the motor shaft should be manually rotated by hand at about 30 rpm for 15 seconds or if power is
available, the motor can be electrically bumped for 5 seconds;

Bearings should be regreased at one (1) year intervals while in storage. Refer to the lubrication plate on the motor
for the amount of grease and the identification of the grease installed at the factory. Use the same or compatible
grease.
DANGER
Rotating machinery.
Can cause death or severe injury.
