ABSTRACT:
A method of flushing a closed loop hydraulic system utilizes a pair of adapters temporarily disposed between a drive motor and a pair of hoses during the flushing procedure. The adapters block communication between the hoses and the motor and cover the inlet/outlet ports of the motor. By connecting a case drain line to one of the adapters and running the engine to drive a charge pump, oil is circulated through the hose connected to that adapter, the case drain line, a case drain line filter and is returned to a tank. The case drain line is then switched to the other adapter so that oil from the charge pump is circulated through the other hose.
