Lubrication & Installation

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.

Shaft Output Units With Mounting Flange

If coupling to shaft – flexible couplings are recommended to
minimize excessive bearing and shaft loading caused by
misalignment. Follow coupling manufacturer’s installation

The exterior holes on this drive are for

mounting the drive or drive accessories (mounting flange,
couplings, sprockets, etc.). They are not to be used for lifting
the drive or any driver/driven equipment. The lifting eye
included on this drive is to be used to vertically lift the drive
only and no other associated attachments or motors.

Installation Instructions

For “C” Flange and Hydraulic Flange Units


Be sure all of the paint and masking have been removed

from the face and pilot of the flange. Check the input bore to
be sure it contains an adequate amount of anti-seize
compound, which is normally installed at the factory. This
compound will inhibit fretting corrosion between the motor or
pump shaft and the unit bore.


Install the key (if round bore) to the maximum depth of

the keyway provided in the bore.


Align keyways or splines of motor or pump and bore of

unit and install motor or pump into frame.


GROVE GEAR “C” flange reducers and

Hydraulic Flange Reducers are designed to accept motors with
shafts that do not exceed the maximum specified by the
N.E.M.A. or SAE standards. If the motor or pump shaft bottoms
out before the motor or pump flange seats against the
reducer flange face, the motor or pump shaft length must be
adjusted to N.E.M.A. or SAE standards.


Secure the motor or pump to the unit. Capscrews and

lockwashers are provided with “C” flange units.


Tightening torques for mounting bolts are provided in the

chart below.

Mounting bolts, coupling fasteners, and other

power transmitting devices should be routinely checked
to ensure that all parts of the unit are firmly anchored to
provide proper operation. (Loose fasteners can cause
alignment problems and excessive wear). Check end play in
shafts. Noticeable movement might indicate service or parts

Make certain that all tools and other items are

clear from rotating parts before starting machine. Stand clear,
and start machine slowly to be sure all components are
secure and operating properly.

Test run unit to verify operation. If the unit

being tested is a prototype, that unit must be of current
production configuration.
