(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 27.
Cut a length of 122-6906 Hydraulic Suction Hose (844) that matches (X) measured distance of tank depth. Install the hose on the filler cap adapter hose barb.

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 only. Other filtration units will have different equation references and these units will be noted when appropriate.
