Expert Maintenance Tips

1. Mounting Orientation: When installing the motor, ensure the motor case drain port is positioned at the highest point to guarantee proper lubrication and air bleeding.

2. Pre-Installation Preparation: Before using the MS11 series motor, read and understand the complete Poclain Hydraulics instruction manual. For first commissioning, fill the motor housing with hydraulic fluid using a filling unit with filtration not less than 10 µm. Never operate the motor without fluid.

3. Bearing Support Selection: The MS11 series offers multiple bearing support types (1110, 1210, 1310, 1610, 1710, 2210, 2250, etc.). Select the appropriate support configuration based on your specific application.

4. Seal Maintenance: For dual-displacement motors, always install new seals during reassembly. Use OEM-specification seal kits to ensure sealing performance and service life.

5. Brake System Maintenance: For motors equipped with brake options, regularly inspect brake pad wear through the inspection port.

6. Case Drain Pressure Monitoring: Regularly monitor case drain pressure to ensure it remains within design limits, preventing excessive housing pressure that could damage shaft seals.

7. Mounting Bolt Torque: Strictly follow the machine manufacturer’s recommended tightening torque. MS11 series mounting bolts should be torqued according to the specific support type and thread specification.
