Lubrication
Lubrication
All standard reducers ordered from the factory are
filled with lubricant to the correct level for the mounting
position specified to operate within a 30° to125° F
ambient temperature range. Quad reduction units have
separate oil sumps and must be filled/checked
independently. Prior to startup, verify that the oil is at the
level shown on the drawings on pages 6 and 7. If the
ambient temperature will be outside the range for the
lubricant installed at the factory, drain and refill the
reducer with the proper viscosity lubricant prior to use.
If the mounting position is changed, the oil
quantity must be adjusted to obtain the proper oil level
per these Lubrication Instructions. Mounting position must
be one shown on pages 6 and 7. Consult the factory if you
are not certain of the correct oil level or quantity. Consult
the factory for mounting positions not shown.
In the Food and Drug Industry (including
animal food), consult the lubrication supplier for
recommendation of lubricants which are acceptable to the
Food and Drug Administration and/or other authoritative
bodies having jurisdiction. Factory supplied oil is not
suitable for these applications or this industry.
Do not mix different oils in the reducer. Oil
should be compatible with Nitrile seal material.
Use of an oil with an EP additive on units
with backstops may prevent proper operation of the
backstop. Injury to personnel, damage to the reducer or
other equipment may result.
Change Intervals: After the first 500 hours or one month
in service, whichever comes first, drain the oil from the
reducer. Flush and refill with new oil. TorqueLine units
utilize extreme pressure lubricants which protect the
teeth in the event of the oil thinning out due to local
temperature rise, or high pressure due to accidental
overloads. These oils are liable to form sludge after
continuous service. The oil should be changed after every
1500 hours of operation, or more often as conditions may
dictate. The grades of oil shown below are for normal
conditions of duty and ambient temperature. High
ambient temperatures cause the oil to thin out and
reduce its protective qualities. In such cases it will be
necessary to utilize heavier grades than shown. Conversely,
low temperatures will necessitate a thinner grade,
otherwise trouble may be experienced with burning out of
motors at starting. In this connection, the pour point of the
oil must be less than the lowest ambient temperature to
be encountered.
The precision-made gears and bearings in Grove Gear
Speed Reducers require high-grade lubricants of the
proper viscosity to maintain trouble-free performance. For
best results, use lubricants on the following chart for
TorqueLine gear reducers for ambient temperatures of 30°
to 125° F.
