  * Conduct detailed dimensional inspections using precision measuring equipment including micrometers, bore gauges, dial indicators, laser alignment tools, and verniers

  * Measure and set bearing preloads, gear backlash, shaft runout, end float, and assembly tolerances in accordance with OEM specifications

  * Perform gearbox failure analysis and identify root causes through detailed component inspection and condition assessment

  * Recondition gearbox housings, shafts, gears, bearing journals, and rotating assemblies using approved engineering and reclamation techniques

  * Assemble and install lubrication systems, oil pumps, cooling circuits, filtration systems, couplings, and associated drivetrain components

  * Carry out inspection and replacement of planetary gear sets, high-speed shafts, intermediate stages, and main bearing assemblies within wind turbine gearbox systems

  * Read and interpret engineering drawings, assembly procedures, technical manuals, hydraulic schematics, and service documentation

  * Support gearbox removal, installation, alignment, commissioning, and functional testing activities both onsite and within workshop facilities

  * Perform mechanical alignment of coupled rotating equipment using laser alignment systems and precision measurement techniques

  * Complete final inspection and testing procedures to verify gearbox operational performance, vibration levels, and assembly quality standards

  * Maintain overhaul records, inspection reports, measurement data, and component traceability documentation in line with quality procedures

Skills & Experience Required

  * Strong mechanical engineering background with proven experience in industrial gearbox overhaul and drivetrain maintenance

  * Experience working on wind turbine gearbox systems or heavy industrial rotating equipment

  * Sound understanding of gearbox internals including planetary gear systems, lubrication systems, bearings, couplings, and shaft assemblies

  * Ability to diagnose and rectify complex mechanical and lubrication-related failures

  * Experience carrying out gearbox retrofit programmes and engineering modifications

  * Competent in precision measurement, tolerance checking, and mechanical alignment procedures

  * Familiar with OEM overhaul standards, quality documentation, and engineering best practices

  * Flexible approach to working hours within a service-driven engineering environment
