Review of AAR M-963-84 Specification for Journal Box Lubricating Oil – Anju Singla, American Refining Group
AAR M-963-84 is an All Year Journal Box (JB) Lubricating Oil specification, last revised circa 1985. Lubrication technology has advanced considerably since that time. Further, confusion between Journal Box lubricating oil and Traction Motor Support Bearing Oil has led to a request for review of the M-963 JB oil specification.
This presentation details findings from the specification review, results of compatibility testing and recommendations for possible amendments to the existing AAR M-963 specification.
