operation and service
The Geareducer vent or vent line must be checked for blockage
to prevent failure of pinion shaft oil seal—clean when necessary.
Once each month
drain any water condensation from the lowest
point of the Geareducer and its oil system. Check the oil level and
add oil if necessary. Perform a
Run Cycle.
To put back into operation
, drain water condensation from the
lowest point of the Geareducer and its oil system and check oil
level. Add oil if necessary.
Long-Term Storage or Downtime
indefinite duration
If unit has been in an operational state, perform a
Run Cycle
and drain the oil including volume in the oil line, if equipped. If in
storage, unit does not need to be operated.
Fabricate and install an overflow reservoir system and fill unit
entirely full of oil.
Maintenance Cycle
If unit is stored outdoors, drain condensate
monthly and top off oil as necessary. If unit is stored indoors,
but not climate controlled, maintenance cycle may be extended
to 3 months. If stored in climate controlled space, cycle may be
extended to once per year.

Inspection Of Internal Parts
Remove the inspection cover plate from the side of the Geareducer
case at each oil change. Check inside of Geareducer for cleanliness
of case and internal parts. If any sludge is present, flush inside of
Geareducer and connecting oil line.
Figure 3
Priming Interstage Shaft
Check all gasketed joints for oil seepage. Tighten cap screws and
flange bolting if necessary.
The Geareducer must be installed level and properly aligned with the
driveshaft and motor shaft. Refer to the
Driveshaft User Manual.
It is recommended to operate the Geareducer for no less than
30 minutes in any given run sequence. It is acceptable to ignore
this when “bumping” the motor for confirmation of the correct
direction of rotation.
Seasonal Shutdown
up to 4 months
At start
of shutdown period, perform a
Run Cycle
and change the
oil. See section on
Changing Geareducer Oil.
Every 2 weeks
check the oil level and perform a
Run Cycle.
Changing Geareducer Oil
Drain the Geareducer oil by removing the drain plug. See
Figure 4
for location. If equipped with an external dipstick/oil
level gauge, remove the drain plug at that location, and drain the
entire system.
When using synthetic oil with extended service intervals remove a
sample for lab analysis and look for evidence of foreign material,
such as water, metal shavings or sludge. If you find unacceptable
condensation or sludge, flush the Geareducer with mineral oil
before refilling.
After inspection is complete, fill the Geareducer with
18.5 gallons
(70 liters) of oil. See
Figure 4
for location. If the Geareducer is
equipped with an external dipstick/oil level gauge an additional 3
to 4 quarts of oil will be required. Be certain that the vent on the
Geareducer (and external dipstick/oil level gauge, if present) is
not plugged. Verify that the gauge/drain line is full and that there
aren't any leaks at the connections.
