Lubrication & Installation

Important Selection Information

Read ALL instructions and safety precautions prior to operating
unit. Injury to personnel or unit failure may be caused by
improper installation, maintenance, or operation.

Check to verify that the application does not exceed the
capacities published in the current catalog.

Written authorization from GROVE GEAR is required to operate
or use gear units in man lift or people moving devices.

The system of connected rotating parts must be free from
critical speed, torsional, or other type vibration, regardless of
how induced. The responsibility for this system analysis lies
with the purchaser of the gear unit.

Buyer shall be solely responsible for determining the
adequacy of the product for any and all uses to which the
buyer shall apply the product. The application by buyer shall
not be subject to any implied warranties of merchantability or
fitness for a particular purpose.


All GROVE GEAR Helical Worm gearmotors and gear reducers
are supplied with the correct quantity of lubricating oil for the
mounting position specified at time of order.

Before Installation

Review the approved mounting positions and

lubrication levels identified on page 4 of these instructions. Do
not deviate from the mounting positions or lubrication levels
shown without contacting the factory.

For transportation, the units are supplied as sealed gearcases,
i.e., in place of the breather plug, a socket head plug is
installed. The breather plug accompanies the unit in the
lubrication instructions and hardware envelope.

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 200 hours of operation, drain out initial oil, and
refill. Thereafter, oil should be changed at least every 2500
operating hours (5,000 for synthetic oil lubricant) or every 6
months (12 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 clean 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.
