(2) 352-5360 Hydraulic Tank and Mounting Gp
(3) 395-4204 Breather Gp
(4) 363-1242 Tank Filler Cap
Loosen the Tank Filler Cap (4) partially to relieve system pressure stored in the hydraulic tank. Clean the area around the Breather Gp (3). Remove the Breather Gp (3) from the hydraulic tank. Store the Breather Gp in a clean place to avoid contamination. Refer to Illustration 22.
Install K - Series adapter assembly on to the hydraulic tank where the Breather Gp (3) was installed.

(X) Proper length of suction hose
(Y) Distance from the top of the filler neck to the bottom of the tank
(Z) 2 inch filler cap adapter = 50.8 mm
(Z) 4 inch filler cap adapter = 101.6 mm
Measure the distance from the top of the hydraulic filler neck to the bottom of the hydraulic tank (Y). Subtract (Z) from (Y) to obtain the proper hose length (X). Refer to Illustration 23.
Cut a length of 122-6906 Hydraulic Suction Hose (844) that matches (X) measured distance of tank depth. Install the hose on to the filler cap adapter hose barb.

(6) Side discharge port with elbow fittingNote: The elbow fitting (6) may be required on larger tractors for the filter cart suction hose to reach and connect to the filler cap adapter. The addition of the elbow fitting will aid in the necessary orientation of the return port. The elbow fitting (6) is pictured in Illustration 25 on the side return port.

(10) Return line
(11) Fill Cap Adapter side discharge port
Connect the filter cart discharge line (10) to the 2 in Fill Cap Adapter Gp. side return port (11). Refer to Illustration 27.Note: Refer to Step 11 of the Filter Cart Setup and Procedure for Wheel Loader Hydraulic Oil section in this document. The Filter Cart Setup and Procedure section contains the remaining steps of the filtration procedure.
When the filtration procedure is complete, remove the 2 in Fill Cap Adapter Gp., install the Breather Gp., and tighten the tank filler cap. Check the oil level by viewing the hydraulic tank sight gauge.Oil Compartment Filtration Times for 188-3242 Filter Cart Gp
If an on-line, portable particle counter is not available to diagnose and track when the contaminant level has lowered to an acceptable level, refer to the following equation. This equation relates to the 188-3242 Filter Cart Gp and the 194-2897 Filter Cart Gp only. Other filtration units will have different equation references and these units will be noted when appropriate.
