Section VII — Vertical Service
NOTE
: ALL EXTERNAL PLUMBING (PIPE NIPPLE,
PIPE PLUGS, FITTINGS) ARE STANDARD NPT
(NATIONAL PIPE THREAD) CONNECTIONS.
Vertical service can be either input, or output shaft
up. Standard reducers are not designed for vertical
applications. Modifications are made at the factory to
convert a standard reducer for vertical service.
Planetgear 7000 speed reducers used in a vertical
orientation or most inclined orientations require an oil
reservoir lubrication system. Any mounting orientation
other than horizontal must be stated at order placement so
Rexnord can determine the requirement for a reservoir kit.
The reservoir kit works by providing an adequate head of
oil to lubricate the uppermost bearing while allowing for oil
expansion. A plastic tube acts as a purge line to eliminate
trapped air below the seals.
CAUTION
: Failure to use a properly installed reservoir kit
will cause premature speed reducer damage.
Assemble components as shown in
Figure 7.1a &
Table 15
, and
Figure 7.2a
&
Table 16
. It is difficult to
determine all potential field installation interference points.
If necessary please substitute different pipe fittings as
required. In doing so, it is important that the bottom of the
reservoir is at or above the uppermost bearing. Holes have
been drilled by the factory to facilitate both right hand or
left hand oil reservoir mounting. Apply pipe sealant to all
threaded connections during assembly.

FILLING OIL
The speed reducer should be completely filled with oil
prior to start-up. Refer to the Lubrication section for correct
oil type and viscosity.
NOTE
: When replacing oil plug, seal it in the process using
thread sealant.
1. Begin by filling the reducer thru the primary oil fill in the
maincase until full. Reference
Figure 7.1a
.
2. Plug primary oil fill and fill thru secondary oil fill until full
if orientation is low speed shaft up.
3. Plug secondary oil fill and fill reservoir until proper oil
level is reached.
4. Start reducer under a no-load condition.
NOTE
: During start-up and initially after, it is important to
monitor the oil level, as any remaining trapped air
may need to purge out. Add oil as needed if this
occurs.
