Lubrication & Installation


For safety, purchaser or user should provide

protective shields over all shaft extensions and any moving
apparatus mounted on the unit. The user is responsible
for checking all applicable safety codes in his area and
providing suitable shields.

A unit cannot be used as an integral part of

a machine super-structure which would impose additional
loads on the unit other than those imposed by the torque
being transmitted, or by any shaft mounted power
transmitting device such as sprockets, pulleys, or couplings.

Units ARE NOT to be considered fail safe or

self locking devices. If these features are required, a
properly sized, independent holding device must be utilized.

For safe operation and to continue the unit

warranty, when installing, reinstalling, or replacing a
factory installed fastener for servicing purpose, or to
accommodate the mounting of guards, shields or other
light load imposing devices, or for mounting the unit, it
becomes the responsibility of the purchaser or user to
properly determine the quality, grade of fastener, thread
engagement, load carrying capacity, tightening, torque, and
the means of torque retention.


Flexible couplings to input and output shafts are
recommended because they minimize excessive bearing
and shaft loading caused by misalignment. Follow coupling
manufacturer’s installation directions.

Shaft Mounted Models

GROVE GEAR recommends application of an anti-seize
compound, such as Dow-Corning® 1000 High
Temperature Anti-seize Paste or Never-Seez®, to the
driven shaft during installation. This assists in preventing
fretting corrosion and aids in unit removal. Driven shaft
should be supported independently with pillow block
bearings. A suitable Torque Arm must be provided and can
be ordered separately (not supplied) to keep unit from
rotating. A torque arm pad can be attached to any of the
four available mounting surface locations of the unit. Install
and position Torque Arm at 90° angle to a line drawn
between the center of the output hollow bore and the bolt
that attaches the Torque Arm to the Torque Arm Pad of the
unit. The Torque Arm should be positioned to be in
tension, NOT compression, based on output rotation of the
gear drive. (Refer to Figure 1). A rigid torque arm an cause
bearings to “load up” and cause premature bearing failure.
To prevent this, provide a slight amount of “float” at the
torque arm pivot points.

Inspect shafts and components for paint,

burrs, or other imperfections before installing components.
Do not use excessive force or pounding to install
components onto unit shafts, as this may cause damage to
shafts, bearings, or gears.

Preventative Maintenance

Keep shafts and vent plug clean to prevent foreign particles
from entering seals or gear case. Inspect periodically for oil

Sheaves and Sprockets

When mounting sheaves or sprockets, they should be
located as close to the Helical Bevel Gear Drive as possible.
Excessive overhung load could result in premature failures
of bearings or shaft. Refer to the general catalog or contact
your local distributor for overhung load ratings.

Any brakes that are used in conjunction with

a unit must be sized or positioned in such a way so as to
not subject the unit to loads beyond the capacities
published in the current catalog.

Flange Mounted Units

Units with the flange mount accessory are to

be mounted and supported by the mounting flange only.
The mounting pads on the housing are not to be used in
conjunction with the mounting flange to support the unit.

Shaft Mounted Units With Mounting Flange

There must be concentricity between the driven shaft and
the machine register that accepts the mounting flange pilot
to prevent misalignment between the hollow shaft of the
drive and the driven shaft.
