K&N was contracted by the United States Coast Guard to completely recondition the four propulsion motors for the USG Cutter Acushnet (a converted WWII salvage ship first commissioned in 1944).

This job involved rewinding of the fields and armatures as well as replacement of two commutators. Several of the shafts and journal fits required machining to government specifications, and of the ten bearings received only two were within tolerance.

Modifications included the installation of RTD's and control panels in the windings for temperature monitoring.
