Gearbox Repair & Upgrade

Expertise in the Service Center, Reliability in the Field

Using state-of-the-art inspection and measurement techniques, we are equipped to answer critical operational questions from our customers. Our goal is to provide the rotating equipment decision makers with the data they need to make informed decisions.

Additionally, by performing a detailed design review of both the gearbox and its application, our engineers evaluate all of the various factors and influences that may have changed over time. Often, in fact, decades have passed since our equipment was first put in service.

This approach helps us determine the up-rate potential of the unit, as well as incorporate any designed upgrades during the repair process to ensure you are getting the absolute most out of your equipment.

Local Service. National Support. Global Expertise.

Our gearbox repair and upgrade services are backed by more than a century of engineering and manufacturing excellence. And though the engineers at Smith Services have immediate online access to more than 4,000,000 technical documents of the TPS proprietary brands, we are backed with in-person support from the engineering and technical center staff at the Philadelphia Gear headquarters in King of Prussia, Pennsylvania.
