The gearbox of your cooling tower is a very valuable asset, and we realize how important it is for you to keep it running at its best. SPX Cooling Technologies has in-house engineers that have been designing Marley Geareducers for over 70 years. Who can troubleshoot and diagnose your particular situation better than the one who designed it? Whether you have questions on Geareducer® operation and maintenance, need components to perform a repair yourself, or want to send your unit back to us for the highest level of care, SPX has the solution.


In-house Marley Inspection and Repair: Send your Marley Geareducer to our Olathe, KS repair facility where we will diagnose the Geareducer condition to determine a level of repair that is most appropriate for your particular gearbox.

Once repaired with genuine Marley OEM components, all units are run-in under load before leaving the factory to ensure they are ready to be put back into service when you need them.

Geareducer Rebuild Kits: Should you decide to tackle the labor yourself, SPX offers multiple kits per Geareducer model that give you all the necessary components to repair your Marley Geareducer; including gears, bearings, seals, and even oil.


SPX knows Marley Geareducers, thanks to over 70 years of designing, assembling, diagnosing and repairing them. The Marley Geareducer will last a long time when properly maintained, but it is important to identify and correct any concerns before they lead to failure. Whether your Marley Geareducer just needs a checkup, or a complete overhaul, send it to our Olathe, KS facility for an inspection and a repair option that will bring your unit back to OEM condition. SPX will even pay the freight to get your Geareducer to our facility, as well as the outbound freight back to you if you choose to proceed with repair. Most components are in-stock for a quick turnaround.


You’ll find a full suite of technical services available to help ensure your operation is efficient, optimized and compliant. Where applicable, our technicians and methodology abide by CTI and ASME guidelines; and regardless of process or procedure, our staff is dedicated to delivering the highest standards of quality and accuracy.

Ultimately, what SPX Cooling Technologies offers is the peace of mind that over a century of cooling tower experience can bring. Because we design, engineer, manufacture, and service world class cooling tower brands, it only stands to reason we understand them better, inside and out.

When you need consultative technical services for your cooling towers—whether it’s to diagnose or upgrade individual units or entire systems—you need to remember only one name: SPX.
