Project Overview
AMS partnered with a locomotive and maritime engine manufacturer to perform the removal, reinstallation, and precision alignment of a test cell alternator and drive line assembly. The project involved handling a 24,000 lb alternator and ensuring exact alignment with the drive system.

The Challenge
This project required extremely tight tolerances, with the alternator needing to be aligned to within 0.060 inches of the driveshaft. The 26,000 lb assembly was mounted on pedestals that required machining and adjustment while working around the installed equipment. Improper alignment would result in vibration issues within the engine, making precision critical. Additionally, the scope included working within a confined test cell environment and reassembling the blast wall upon completion.

Our Approach
AMS utilized precision tools including machinist levels, micrometers, and torque wrenches to achieve exact alignment. Our team carefully lowered and positioned the alternator using a 40/60 Versa-Lift, while machining pedestal surfaces and making fine adjustments to achieve required tolerances.
Supporting work included welding, electrical integration, and full reassembly of the blast wall. Every step was executed with detailed coordination to ensure accuracy and system performance.

The Result
The alternator and drive line assembly were successfully installed and aligned within the required tolerances, ensuring proper operation and eliminating the risk of vibration issues. The project was completed safely, efficiently, and to exact specifications—delivering a fully operational test cell.
