Drive Motor
(1) Oil line. (2) Drive motor.3. Remove oil line (1) from drive motor (2). Install a 5W7272 Hose to the drive motor port. Guide the end of the hose into a suitable container.4. Install a 8U1757 Plug, a 5W7880 Fitting and a 5W1640 Nut to the end of oil line (1).5. Select high gear at the console.6. Adjust the governor control lever to high idle.7. Operate directional controls in forward.8. Measure the amount of oil flowing from the drain hose into the container during one minute. Use the stopwatch. Drive motor case drain oil flow must not exceed 10 liter/min (2.6 U.S. gpm).Bleeding Procedure For Hydraulic System
After removing and installing hydraulic components and hydraulic lines, there may be air in the system. This air must be completely removed to avoid damage to the components.Bleeding Main Pump
This procedure is only required if the main pump has been removed or replaced.1. Make sure the engine is stopped. Check the hydraulic oil level on the sight glasses of the hydraulic oil tank. If the level is not correct, refill the tank to the specified level.
Bleed Main Pump
(1) Plug.2. Loosen plug (1) on top of the main pump.3. When there is no air in the oil flowing out of the plug opening, tighten the plug.Bleeding Main Control Valves
Refer to on first page of Testing And Adjusting section
1. Start the engine and adjust engine speed to 1200 rpm.2. For the 214B, 214B FT & 224B, apply the parking brake by setting the brake control lever in the operator's cab to position "P".3. Engage the swing lock pin.4. Bleed one control valve at a time. For each implement or circuit, loosen the plug at the top of the control valve. Slowly operate the control for the implement. Do not fully extend cylinders or operate swing and travel controls at full speed.
Bleed Plug Location On Main Control Valves
(1) Auxiliary implement circuit. (2) Stick cylinder. (3) Hammer circuit. (4) Bucket cylinder. (5) Left track motor for 213B or travel motor for 214B, 214B FT & 224B. (6) Right track motor for 213B or stabilizer/dozer cylinders for 214B, 214B FT & 224B. (7) Boom cylinders. (8) Swing motor.5. When there is no air in the oil flowing out of the plug opening, tighten the plug.6. Repeat this procedure on each control valve until all control valves are bled. Apply brakes when bleeding travel and swing main control valves.Bleeding Axle Stabilizer Cylinders (214B, 214B FT & 224B)
Refer to on first page of Testing And Adjusting section
1. Start the engine and adjust the engine speed to 1200 rpm.2. Apply the parking brake.3. Set the service brake and axle stabilizer control lever to position "F" (travel position, axle stabilizers unlocked).
Axle Stabilizer Cylinder
(1) Plug. (2) Axle stabilizer cylinder.4. Loosen plug (1) on left or right
