Sprocket (left travel) (G) Track block (1) Sprocket
Place track block (G) in sprocket (1) in order to block forward left travel. Refer to Illustration 5.
Stop the engine.
Release the pressure in the hydraulic system. Refer to Testing and Adjusting, "System Pressure - Release".
Attach 311-1362 Vacuum Cap onto the hydraulic tank. Attach an air supply hose onto the assembly. Apply 276 to 414 kPa (40 to 60 psi). This procedure will pull a vacuum on the hydraulic system.

Flow Meter Tool LayoutTooling (D) (2) Case drain hose (3) Connector (4) Travel motor
Install the following tools in accordance with the flow meter tool layout. Refer to Illustration 6.
Disconnect case drain hose (2) from connector (3) .
Connect the flow meter assembly (D) between connector (3) and case drain hose (2) .Note: Correct orientation of the flow meter is necessary. The oil flows from travel motor (4) to case drain hose (2) .
Remove 311-1362 Vacuum Cap .Test Procedure
Start the engine.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF.
Place the hydraulic activation control lever in the UNLOCKED position.
Move the left travel lever to full FORWARD position and check the flow of oil through the flow meter. Refer to Table 1.
Remove track block (G) from sprocket (1) .
Move the left travel lever in order to reposition the travel motor.
Place track block (G) in sprocket (1) in order to block forward left travel.
Repeat Steps 5 through 8 in order to obtain three measurements of case drain oil.
