Military Engine Oils as Hydraulic/Power Transmission Fluids in Army Commercial Construction Equipment.

摘要

In 1971, the Army adopted a policy of procuring commercial-type construction and other off-highway equipment, referred to as CCE. With this equipment comes the equipment builder's warranty which requires use of hydraulic power transmission fluid (HPTF) which meets his specification. The fact that many different equipment suppliers will ultimately furnish their products to the military under this arrangement leads to the possible proliferation of proprietary fluids in the government supply system. To counteract this possibility, and hopefully eliminate such proprietary fluids, MERADCOM/AFLRL undertook an extensive experimental program aimed at determining the feasibility of using existing government-stocked lubricants in CCE HPTF systems. Fourteen test oils were compared against the John Deere proprietary reference oil in laboratory bench, wet-brake, and full-scale wear tests. Lubricants included nine qualified Military Specification engine oils, three commercial automatic transmission fluids (ATF), and two commercial type tractor hydraulic fluids. The military specification automotive engine lubricants, namely MIL-L-2104C OE/HDO-10, MIL-L-46167 OEA, and MIL-L-46152 grade 10W-30 proved to be equal or better in regards to gear wear than the John Deere proprietary fluid.
