Final Drive Hydraulic Travel Motor - AM16

Final Drive Hydraulic Travel Motor – AM16

Genuine replacement final drive travel motor for the AM16 1.6T mini excavator. Delivers power from the main hydraulic pump to the track drive sprockets, enabling forward/reverse and speed control.

Specifications

• Type: Axial piston radial motor (bent-axis design)
• Displacement: 56–60 cc/rev
• Max Operating Pressure: 16 MPa (160 bar)
• Flow Rating: 35–45 L/min at rated pressure
• Max RPM: 350 rpm (continuous duty)
• Torque Output: 110 Nm at rated pressure
• Port Connections: SAE flange (ISO 4401-05)
• Rotation: Bi-directional (forward/reverse)
• Case Drain: Required (separate return line to tank)

Compatibility

Fits: AM16 1.6T mini excavator (Laidong KM385 engine)

Hydraulic System: 16 MPa (160 bar) rated system

Note: Not compatible with AM10 or AM12 (different displacement and pressure specs)

Function & Performance

• Power Delivery: Converts hydraulic flow to mechanical motion for track propulsion
• Speed Control: Proportional flow control delivers smooth variable-speed operation
• Efficiency: Bent-axis swashplate design optimizes power transfer
• Duty Rating: Rated for continuous grading and travel (6–8 hours/day)

Installation Notes

• System pressure must be 16 MPa (check before installation)
• Flush all hydraulic lines with clean ISO VG 46 fluid
• Install new seals and gaskets (included with replacement)
• Case drain line MUST be connected to tank (not pressure line)
• Prime motor with fluid before first operation to prevent cavitation
• Bleed air from motor casing after connection
• Test track movement through full range under light load

Maintenance

• Change hydraulic fluid every 500 operating hours
• Replace fluid filter every 250 hours
• Inspect case-drain line quarterly (ensure unrestricted flow)
• Monitor for slow travel speeds (sign of internal wear or pressure loss)
• Check for oil leaks around shaft seal monthly
