Hydraulic Pump & Motor Technician

Responsible for the inspection dismantling repair refurbishment assembly testing and troubleshooting of hydraulic pumps and motors used in both open-loop and closed-loop circuits The technician should have strong practical experience with various types of hydraulic pumps and motors including their control systems and must be capable of identifying component wear carrying out precision measurements replacing required parts and performing performance bench testing as per the hydraulic control schematic and manufacturer s specifications

Key Responsibilities

• Dismantle and assemble hydraulic pumps and motors safely and correctly
• Inspect and assess internal components for wear damage scoring cavitation corrosion and other defects
• Carry out precision dimensional inspections using o Micrometerso Vernier caliperso Dial gaugeso Other appropriate precision measuring instruments
• Inspect and measure critical components including o Pistons o Cylinder blocks o Valve plates o Swash plates o Shafts o Bearings o Bushes o Servo and control components
• Identify the root cause of pump and motor failures
• Replace seals bearings O-rings retaining rings and other required spare parts
• Carry out lapping polishing and other component restoration processes whererequired
• Check critical component clearances and ensure they are within the manufacturer sspecifications
• Read and interpret hydraulic schematics assembly drawings parts lists controlcircuits and service manuals
• Maintain proper identification and traceability of components during dismantling inspection repair and assembly
• Assemble pumps and motors according to manufacturer specifications andrequired torque values
• Carry out pre-testing inspections before mounting the unit on the test bench
• Perform pressure flow displacement leakage efficiency and functionaltesting of pumps and motors according to the control schematic andmanufacturer s test procedures
• Troubleshoot pumps and motors during testing and identify abnormal noise vibration leakage pressure loss flow loss or other performance issues
• Verify the operation and adjustment of pump motor control systems during benchtesting
• Record test results inspection measurements repair findings and control settingsaccurately
• Prepare service reports and inspection reports when required
• Assist with site troubleshooting removal installation commissioning andperformance testing of hydraulic pumps and motors
• Support servicing and repair of high-pressure hydraulic equipment and RESATOsystems where applicable
• Maintain workshop tools test benches measuring instruments and equipment ingood working condition
• Follow all company HSE procedures and safe working practices
• Maintain good housekeeping and workshop discipline
• Work independently and effectively as part of a team
