Attach the fabricated particle counter "low pressure in" suction tube to the S O S valve (31) on the filter cart. Refer to Illustration 17.Note: The fabricated suction tube can be made from parts listed in Table 3 and as shown in Illustration 17.
Attach the other end of the fabricated suction tube to the "low pressure in" port on the portable particle counter as called for in the Tool Operating Manual.Bottle Sample Procedure

(31) S O S valve (32) 169-8373 Bottle Group
If collecting a bottle sample, use the sample S O S valve (31) and a 169-8372 Bottle Group (32). Refer to Illustration 18.
Record an oil sample from the S O S valve (31) on the filter cart at the beginning of the filter cycle.Note: Kidney Loop filtration can be performed while the engine is running.
At the halfway point of filtration, stop the procedure and change the machines hydraulic filters. Changing the filters allows the filters to assist in system cleaning. The new filters can remain in place until the next scheduled filter change. Changing the filters at this time avoids opening the filter housing after the system has been cleaned. An open filter housing is an inlet for contamination.Note: The filters only need replaced if the filters are not working at optimal performance or scheduled to be changed.
During the filter cart operation, cycle the lift cylinders at least four times every half an hour of the cart operation. This action will cycle the clean tank oil into the hydraulic system and flush the more contaminated oil back into the tank.
Operate the filter cart until the portable particle analyzer indicates that the oil has reached an ISO level of at least 18/15. The final ISO level should be recorded before the machine is returned to the field.
When the target ISO level or time interval has been met, close the air supply valve (27). Disconnect the air supply hose (26). Refer to Illustration 15.Note: Refer to ""Oil Compartment Filtration Times for 204-7392 Filter Cart"", located at the end of this document, when a portable particle analyzer is not available.
Disconnect the filter cart discharge hose (24) from the return oil adapter (20). Install the dust cap on the coupler and on the nipple. Store the coupler and store the nipple in a clean location. Refer to Illustration 13.
Disconnect the filter cart suction hose (25) from the suction adapter (23). Install the dust caps on the coupler and nipple. Store the coupler and store the nipple in a clean location. Refer to Illustration 14.
Turn on the air supply to the vacuum transducer assembly (21). Refer to Illustration 10.
Quickly remove the suction adapter (23). Install the drain plug (22). Refer to Illustration 12 and Illustration 11.
Turn off the air supply to the vacuum transducer assembly (21). Refer to Illustration 10.
Remove the return oil adapter (20). Refer to Illustration 10.
Remove the return oil fastener (19). Refer to Illustration 9.
Install the filler cap base assembly (18). Refer to Illustration 8.
