LUBRICANTS FOR MARLEY GEAREDUCERS
To insure maximum performance and service life, The Marley
Cooling Tower Company recommends Marley factory ap-
proved oils be used in all Marley spiral bevel Geareducers. You
can purchase Marley approved oils through your local Marley
sales office in one-gallon and five-gallon containers.
If you must use any oil other than Marley factory approved oil,
the lubricant must not contain any additives (such as deter-
gents or EP additives) which are adversely affected by mois-
ture and could reduce the service life of the Geareducer. The
responsibility for use of oils other than Marley approved
lubricants rests with the customer/user and the lubricant
supplier.
Seasonal temperature changes may require one viscosity of
oil for summer operation and another for winter operation. Use
the following table as a guide.
The Mobil synthetic lubricants listed below may be used where extended service intervals are desired (up to five years).
