NEW AND RECONDITIONED MACHINES SHOULD NOT EXCEED 15% FLOW LOSS IN SYSTEM TEST. THE FLOW DIFFERENTIAL THAT CAN BE TOLERATED BEFORE REPAIRS ARE NECESSARY IS DETERMINED BY THE MACHINE APPLICATION. DECREASED SYSTEM EFFICIENCY OF A MACHINE ON A SHORT OPERATING CYCLE (LOADING( IS MUCH MORE CRITICAL THAN THAT OF A MACHINE ON A LONG OPERATING CYCLE (HAULING). *WORN OR MALFUNCTIONING COMPONENTS ARE LOCATED BY THEIR FLOW DIFFERENTIAL AND PERCENT FLOW LOSS OR LOWER SYTEM EFFICIENCY.
