The paper provides a detailed interpretation of the analytical data generated during a two year field trial of an ISO VG synthetic gear lubricant in 16 AC electric wheel motors. The field trial was undertaken as part of the wheel motor manufacturer’s oil qualification program. The paper’s primary focuses are analytical wear trends and air inducted abrasives contamination management as well as physical measurements of certain components.
