Dynamometer and Test Cell Repair, Remanufacture, and Upgrades

Repairing, Rebuilding, and Improving Dynamometer Systems Across Industries

Building and Rebuilding Testing Systems Built to Last

We repair and rebuild about every make and model of eddy current, AC, DC and water brake (hydraulic) dynamometer. We work with every major dynamometer brand, including GE, Midwest, Eaton, Dynamatic, Schenck, Borghi & Saveri, Froude, Hofmann, Horiba, Meiden, Zollner, AVL, SAJ and many more. Whether your dynamometer is simply not performing the way that it used to, or your needs have changed and your dynamometer is no longer keeping up, we can help. From advanced test cells fully-integrated with driveline, fluid, and exhaust ​systems to relatively simple, stand-alone dynamometers, our engineers are able to repair, remanufacture, and upgrade a wide range of testing equipment.

  • Repair and Remanufacture: We work with old and worn-out dynamometers of all kinds, including eddy current, water brake, AC, DC, tandem and hybrid models.  Our repair or remanufacture services are able to bring your dynamometer to better-than-new OEM performance.
  • Dynamometer Upgrades: Over decades of experience designing and building dynamometers, we have learned how to integrate old dynamometers with new technology to boost performance. We have substantially improved the performance of dozens of different dynamometers and full test cells.
  • Remanufactured Dynamometers In-Stock: We inventory a variety of makes and models of dynamometers ready to be remanufactured to your application. We stock, repair, and rebuild dynamometer cores to fully restore them. Once finished, you receive a like-new dynamometer for a fraction of the price that you would pay for a new dynamometer.

Having trouble with your dynamometer?

Repaired, Remanufactured, Dynamometers

Full Restoration and Upgrades for Any Dynamometer Model

We not only design and build new dynamometers that are made to last, but we also restore a full range of existing models and configurations. We replace worn-out components, remanufacture and reconfigure the machinery when needed, and even perform innovative upgrades to boost performance beyond the original OEM operation.

Eddy Current (EC)

Address issues like magnetic wear and rotor degradation in your EC dynamometer to maintain efficiency in steady-state testing. Upgrading can improve control and resistance capabilities, ensuring continued low-maintenance performance while enhancing durability and test accuracy.

Alternating Current (AC)

Restore or even improve the motor control systems and precision testing capabilities of your AC dynamometer. We can replace worn components and restore the dynamometer’s performance to like-new conditions. These services enhance reliability and extend the dynamometer’s lifespan while improving accuracy for dynamic testing applications.

Water Brake (WB)

Restore the fluid management systems and braking components in your water brake dynamometer to ensure its continued effective functioning. Remanufacturing allows for restoring high-load testing performance, while upgrades can modernize control systems, providing more precise load handling and reducing water consumption.

Inertia

Repairing and upgrading inertia dynamometers involves enhancing the mass and rotational systems to ensure accurate testing of acceleration and deceleration. Remanufacturing restores mechanical integrity, and upgrades can integrate new data acquisition systems, improving test precision for various speed ranges.

Driveline

With repairs and remanufacturing, we can restore the durability of the drivetrain dynamometer components and ensure accurate torque transmission. Upgrades enhance the dynamometer’s ability to handle high-stress testing, improving performance across a range of drivetrain applications.

CAT Remanufacturing Corinth, MS

The CAT Remanufacturing facility in Corinth, MS Desired to expand test capabilities. The goal was to construct a new test cell with infrastructure and equipment capable of testing engines from 95 to 7,000 hp using both diesel and natural gas fuels. The execution of this project would expand rebuild capabilities and simplify rebuild logistics. With an engineering study and full-scale project management, we worked closely with CAT to perform massive upgrades to their existing system. After completion, “Test Cell #6” was able to successfully test a greater range of engines than any other test cell has previously been capable of in the North American market.

Restore Your Dynamometer

If your dynamometer isn’t performing as well as it used to, or your requirements have changed, remanufacturing and upgrades can help your system meet expectations again.

Our Repair, Remanufacture, and Upgrade Process

Restoring and upgrading your dynamometer is a careful process. Our engineers work through a step-by-step process to inspect every part, identify issues, and solve them. We replace worn-out parts, thoroughly clean all components, and document every step in the process.

Receiving and Inspecting

Prior to inspections, we first receive pictures of the dyno. Then, upon receiving the dyno, we perform a physical inspection. We check the end play and shaft run outs, and then completely dismantle the dyno. During this process, we carefully measure and record the mechanical and critical fits, test and physically inspect all electrical items, inspect the rotor bearings, and identify the cause of failure. Throughout this process, we record all inspections with a 6 to 8 page job inspection form and 30 to 50 images.

  • We receive and inspect the dyno
  • Dismantling the dyno
  • Complete inspection of all components
  • Careful written and visual record-keeping

Quote, Purchase Order, and Delivery to Machine Shop 

At this point, we provide you with a quote. We store the dyno in our temperature-controlled facility and then issue a purchase order at no cost to you. Once a purchase order is received, we thoroughly clean all parts. Then, your dyno goes to the machine shop, where all appropriate work is performed according to your specific dyno work scope.

  • You receive a quote and purchase order
  • All parts are cleaned
  • Your dyno is delivered to the machine shop for restoration

Reconditioning

At this stage, all electrical items are reconditioned or, if needed, newly manufactured and replaced. Your dyno then moves to the assembly departments to be reassembled. After reassembly, we thoroughly check and test for bearing temperatures, coil function, water leaks, case temperatures, vibration, and any other anomalies and performance. During this process, we carefully record finish sizes on all parts and critical fits, and take pictures.

  • Reconditioning and replacing all electrical items and wear parts
  • The dyno is reassembled
  • Thorough performance testing
  • Careful recording of finish sizes and critical fits

Finishing

With your dynamometer completely restored, reassembled, and tested, we perform a final quality check. If the dyno passes these checks, it then moves to the paint booth for finishing according to your preferred colors. Finally, we prepare your dyno for its passage back home, and conduct a final quality check before sending.

  • We perform a final quality check
  • The dyno is painted according to your preferences
  • Another quality check is performed
  • We send your dyno back to you
