1 1 RESERVOIR 1/2 GALLON (1.89L)
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 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 and Table
7.1b. 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.
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.
DRAINING OIL
CAUTION : Oil may be hot. Do not drain oil until oil is at
ambient or a safe temperature.
NOTE : When replacing oil plug, seal it in the process using
thread sealant.
1. Begin by draining oil from main oil drain in maincase.
Reference Figure 7.1a.
2. Plug main oil drain and begin draining oil from final
bearing drain.
