Scheduled Maintenance
Warning
—Make certain that mechanical equipment is inoperable
during periods of maintenance—or during any situation of possible
endangerment to personnel. If your electrical system contains
a disconnect switch, lock it out until the period of exposure to
injury is over.
Monthly
—Check Geareducer oil level. Shut down the unit and
allow 5 minutes for the oil level to stabilize. Add oil if required,
noting the addition in your maintenance log. If equipped with an
external dipstick/oil level gauge, small quantities of oil can be
added at that location.
Semi-annually
—Check that all the assembly bolts and cap screws
are tight, that oil plugs and pipe connections are in place and free
from leaks, and that the vent on the Geareducer (and external
dipstick/oil level gauge, if present) is clear—a clogged vent can
lead to oil leaks. Intermittent operation and extended periods of
downtime can cause condensation of water in the oil. If using
Marley Gearlube, the oil condition must be inspected every six
months—see
Changing Geareducer Oil
for maximizing service
life. If using turbine-type mineral oil, change oil—see
Changing
Geareducer Oil
for instructions.
Annually
— Check mechanical equipment anchor bolts, drive shaft
coupling bolts, and coupling set screws. Tighten as required.
Every 5 Years
—Change oil. Geareducer was designed for 5-year
oil change intervals. Perform Monthly and Every Six Months
maintenance checks prescribed above. To maintain five-year
change intervals, use only Marley Gearlube.
Changing Geareducer Oil
Drain the Geareducer oil by removing the drain plug. See
Figure 1
for location. If equipped with an external dipstick/oil
level gauge, remove the drain plug at that location, and drain the
entire system.
To maximize service life of the Geareducer, remove a sample from
the drained oil and look for evidence of foreign material, such as
water, metal shavings or sludge, or send the oil sample to an oil
analysis lab for inspection. If you find unacceptable condensation
or sludge, flush the Geareducer with mineral oil before refilling.
After inspection is complete, fill the Geareducer with 9.5 quarts
(9 liters) of oil. See
Figure 1
for location. If the Geareducer is
equipped with an external dipstick/oil level gauge an additional 2
to 3 quarts (1.9 to 2.8 liters) 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.

Protection Against Corrosion
Check Geareducer exterior yearly and touch up with epoxy paint if
required. If your Geareducer is equipped with an oil gauge and drain
line, coat any exposed threads at pipe joints to prevent corrosion.
Repair and Overhaul
The Model 1800 and 2000 Geareducer is assembled using
specialized tools and fixtures. Bearings and gear sets are unique and
not available from other sources. Geareducers can be repaired in
the field—however, major repairs require the use of a fully equipped
machine shop. Refer to the
Field Repair
section of this manual
for further instructions.
If your Geareducer ever needs replacement or repair, we recommend
returning the unit to a Marley factory service center. Contact your
Marley sales representative to discuss course of action. A factory
reconditioned Geareducer carries a one year warranty. The Marley
cooling tower order number will be required if the Geareducer is
shipped back to the factory for repair. Obtain a
“Customer Return
Material”
tag from the Marley sales representative in you area.
