Lubricants
To insure maximum performance and service life, it is recommended
Marley factory lubricants be used in all Marley Geareducers.
Marley lubricants can be purchased through your local Marley
sales representative.
Note—Geareducer is designed for 5-year oil change intervals. To
maintain five-year change intervals, use only Marley Gearlube.
Marley Gearlube must be inspected every six months to ensure
the oil has not been contaminated. If turbine-type mineral oil is
used the oil must be changed every six months.

If lubricants other than Marley factory lubricants are used, they must
not contain any additives (such as detergents or EP additives) which
are adversely affected by moisture and could reduce the service
life of the Geareducer. The responsibility for use of lubricants other
than Marley factory lubricants rests with the customer/owner and
the lubricant supplier.
Seasonal temperature changes may require one viscosity of oil for
summer operation and another for winter operation. Refer to the
tables below for the seasonal selection information.
