Note: It is recommended at least weekly, that the general operation and condition be observed. Pay particular
attention to any changes in sound or vibration that may signify a need for closer inspection.
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—If using turbine-type mineral oil, change oil—see
Changing Geareducer Oil for instructions. 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 synthetic Marley Gearlube, the oil condition
must be inspected every six months—see Changing Geareducer
Oil for maximizing service life.
Annually—Check mechanical equipment anchor bolts, drive shaft
coupling bolts, and coupling set screws. Tighten as required. Check
Geareducer exterior yearly and touch up with epoxy paint if required.
Coat all exposed threads at pipe joints to prevent corrosion.
Every 5 Years—If using synthetic Marley Gearlube, change oil.
To maintain five-year change intervals, use only synthetic Marley
Gearlube. It is recommended to monitor the oil condition every
six months throughout the five-year period per the instructions in
Changing Geareducer Oil.
