Test setup consisted of two PLH-1400 gearboxes which were run back-to-back.


The left gearbox was filled with NUFLUX™ formulated gear oil, the other with a commercial PAO gear oil. Temperatures and oil pressures were measured at 8 and at 3 spots, respectively. Gears were painted to examine the contact patterns. 

THE RESULT:
Contact patterns did not show any abnormal behavior. All contact patterns were good and no hard end contacts or marks of particles were detected. The NUFLUX™ formulation passed the factory test and is permitted in field tests.
