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

 

spxcooling.com

.

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

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.
