Lubrication & Installation
Before Operating
After final installation, install the breather plug in the
location specified on page 4 for the appropriate mounting
position.
Do not operate the unit without making sure
it contains the correct amount of oil. The oil level is correct
when surface of the oil is level with the lowest point of the
level plug shown on page 4.
Do not overfill or underfill with oil. This could
result in damage to unit and/or injury to personnel.
Changing Lubricant
After the first 100 hours of operation, drain out initial oil,
and refill. Thereafter, oil should be changed at least every
7500 operating hours (15,000 for synthetic oil lubricant) or
every 18 months (36 months for synthetic oil lubricant) —
whichever occurs first.
Oil should be changed with greater
frequency if unit is used in a severe environment such as
dusty or humid.
If the unit cannot be located in a clear and
dry area with access to an adequate cooling air supply,
then precautions must be taken to avoid ingestion of
contaminants such as water, and to avoid a reduction of
cooling ability due to exterior contaminants.
Wear protective clothing and eye shields
when installing or maintaining unit and machine.
Oil, housings, and other components can
reach high temperatures during operation, and can cause
severe burns. Use extreme care when removing lubrication
plugs and vents while servicing the unit.
Variations From Normal Conditions
Input speeds other than 1750 rpm, may require an
adjustment in the oil level. Consult GROVE GEAR for special
lubricant recommendations when operating at higher or
lower speeds.
APPROVED LUBRICANTS
LUBRICANT AGMA ISO-ASTM
NUMBER VISCOSITY GRADE
Mobilgear 630 5 EP 220
For continuous operation of Helical Bevel Gear Drives
with ambient temperature of 30-125°F (0 to 52°C) and
operating temperature to 185°F (85°C).
MOBILGEAR 630 LUBRICANT is a heavy duty industrial
gear lubricant containing sulfur phosphorous antiwear
additives. Lubricants of this general type and meeting the
above specifications may be substituted where
MOBILGEAR LUBRICANTS are recommended.
Lubricant selected must be compatible with nitrile rubber
seals. For ambient temperature above 125°F (52°C), below
30°F (0°C), operating temperature above 185°F (85°C), or
intermittent duty, consult the factory.
ALL TEMPERATURE SYNTHETIC
75W-90 LUBRICANT (MOBILUBE SHC ® 75W-90)
MOBILGEAR SHC 75W-90 LUBRICANT is a premium gear
box lubricant which is recommended for Helical Bevel Gear
Drives in most applications, especially those subject to low
start up temperature and/or high operating temperature.
This lubricant is a synthesized hydrocarbon based material
and a sulfur-phosphorous gear lubricant additive which
provides longer lubrication intervals because of its
increased resistance to thermal and oxidative degradation.
This decreases maintenance costs. Further economy is
realized because of the increased efficiency of units
lubricated with MOBILGEAR SYNTHETIC LUBRICANT. This
lubricant can be operated at temperatures considerably
above 185°F (85°C). However, the factory should always be
contacted prior to operating at high temperatures as
damage may occur to seals or other components. Lubricant
manufacturer and GROVE GEAR should be contacted when
substituting a premium lubricant where SYNTHETIC
lubrication is recommended. GROVE GEAR should also be
contacted for proper lubricant selection for ambient
temperatures below 30°F (0°C) or intermittent duty.
Do not mix nonsynthetic and synthetic oil in
the unit.
If unit is used in the food or drug industry
(including animal food) consult the petroleum supplier or
GROVE GEAR for recommendation of lubricants which
meet the specifications of FDA, USDA and/or other
authoritative bodies having jurisdiction. Standard lubricants
are not suitable for these applications or these industries.
Installation
Make certain that the power supply is
disconnected before attempting to service or install the
unit, or remove or install any components. Lock out the
power supply, and tag it to prevent unsuspected
application of power.
