- Gas Turbine LM2500 Mechanical Maintenance Training
COURSE OVERVIEW
This customer tailored 5-Day training course covers all aspects of the GE LM2500 gas turbine maintenance with the focus on maintenance procedures required to put the unit back to operational condition by removal, replacement, or adjustment of external parts in the applicable Operation and Maintenance manual part of level 1, level 2 (hot & cold) and borescope inspection.
This training is intended for customer personnel, i.e. Mechanical technicians, and supervisors responsible for the hands- on maintenance of the GE LM2500 Aeroderivative gas turbine.

5 DAYS

TCS-AE0403

PRE-REQUISITES
A basic understanding of the LM2500 gas turbine or completion of the LM2500 Engine Familiarization course, as well as a reasonable level of mechanical skill and use of hand tools is required.
COURSE OBJECTIVE
This course will provide a proficiency level of knowledge on the maintenance of the LM2500 aeroderivative Gas Turbine. The purpose of the training is to provide the knowledge required to ensure consistent, trouble-free maintenance and operation of the engine and its associated auxiliary systems.
This also includes:
- Terminology and abbreviations used in the Aero-derivative Gas turbines.
- GT frames, cases and rotors (High Pressure Compressor (HPC), High Pressure Turbine (HPT), etc.)
- Different levels of maintenance.
- Preventive maintenance.
- Replacement of components. (variable geometry actuators, hydraulic control unit, variable geometry pump, lube and scavenge pump, pressure and temperature sensors, fuel nozzles, accelerometers, ignition components, starter, speed sensors, air/oil separator, carbon seals, pipes, and hoses).
- Removal, inspection, and re-installation of internal engine components. (radial drive shaft, inlet gear box, accessory gear box, front frame, #3 bearing inner race, HP compressor case, HP compressor rotor blades).
- Removal, inspection, and re-installation of internal engine components. (turbine mid-frame, stage 1 HP nozzle, HP turbine rotor, stage 2 HP turbine nozzle, fuel nozzles (SAC), combustor.
- Borescope inspection terminology, boundaries, equipment, and procedures.
