Abstract:
The purpose of RULL (Remaining useful life of lubricant) assessment for heavy earth moving machines is to estimate the time at which the lubricant in a particular system has degraded to the point where it no longer performs its function to the required level, and continued use of the lubricant beyond this point may result in catastrophic failure of the equipment. Even after the requisite number of operating hours have passed, previous experience has shown that the oil has some residual life. It is desirable to maximize its use in order to save these limited resources while avoiding failures. Currently, the choice to continue using the oil or change it is dependent on the recommendation of the equipment manufacturer and the plant's previous experience. The suggested oil change interval is conservative and leads to the rejection of useable oil.
