Oil Maintenance Schedule
Drain, flush, and refill with oil after 2 to 3 weeks of initial break-
in operation. Since the satisfactory operation of the bearing
depends entirely on an oil film being maintained between the
shaft and the bearing liner surface, it is recommended that an oil
analysis be performed at these regular intervals.
•
Every 3 months for 24 hour/day service
•
Every 6 months for 8 hour/day service
Acceptably of oil should be referred to the lubricant manufacturer.
If oil quality is acceptable then repeat this procedure in 3 month
intervals. Visually check oil for contamination between oil analysis
checks. Oil service life depends upon several factors such as
ambient conditions, operating temperature and frequency of
bearing starts and stops. It is recommended that the oil be
changed at least once per year for unfiltered static applications.
Removing contaminants through the use of either the OLF 2
(Oil Level and Filtration 2) Unit or a circulating oil system can
extend oil service life. Consult equipment manufacturer for more
information.
Any questions about installation, maintenance, and arrangement
of coolant or oil connections should be referred to the equipment
manufacturer.
NOTE: Isolators or Auxiliary Seals are recommended for
outdoor applications, contaminated atmospheres, and high
volume air flowing over the bearing.
Temperature
The bearing temperature will increase after start-up until its
normal operating point is reached. The normal operating
temperature should not exceed 180
°
F. Make sure to check
with the OEM for the specified normal operating temperature.
An alarm temperature should be set at 15
°
F above the normal
operating temperature. A shut-down temperature should be
set at 30
°
F above the normal operating temperature. Some
fluctuation due to ambient temperature change is normal.
Low ambient and operating temperatures can be as harmful to
the bearing as high temperatures. The Dodge heater / thermostat
combo can be used in these low ambient conditions.
The Dodge heater / thermostat combo turns on at 70
°
F and
turn off at 100
°
F to ensure proper oil sump temperature during
operation.
NOTE: The recommended oil temperature at start-up is 70°F
MINIMUM.
CAUTION: If heaters are used, be sure heaters are off when
oil is removed from bearing.
WARNING: When installing heater and thermoswitch, follow
directions and safety procedures recommended by the
manufacturer. Install wiring in accordance with the National
Electrical Code and local codes. Failure to observe these
guidelines could result in electrical shock.
Vibration
Any significant vibration or imbalance MUST be corrected.
Check with equipment manufacturer for acceptable conditions.
