Repair and Overhaul
If your Geareducer ever needs replacement or repair, SPX Cooling
Technologies recommends returning the unit to a Marley factory
service center. Contact your Marley sales representative to discuss
a course of action. The Marley Order Number on your cooling
tower 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. To find your Marley
sales representative call
913 664 7400
or check the internet at

.
Major repairs require the use of a fully equipped machine shop.
If you decide to repair or overhaul your Geareducer, refer to the
Field Repair
Section and Geareducer

Suggested Lubricants
The following list of lubricants in
Table 1
is provided as reference
only. These products have been recommended by their respective
manufacturers as acceptable for use in a Marley spiral bevel and/
or helical Geareducer for cooling tower applications. This list is
not an attempt to include all the lubricants that may be satisfac-
tory. If lubricants other than those listed 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. Suitability of lubricants used other than
those listed rests with the customer/owner and lubricant supplier.
