To Get to Know How Disassembly of Gas Turbine Engine is Being Done. ii. Tools & Equipment : Thickness Gauge @ Filler Gauge Socket Set & Extension Masking Tape Jack Screw Philips Screwdriver Flat Screwdriver Mallet Wire Cutter Spanner Set Magnifying Glass Vernier Calliper . What Components are require to be Repair or Replace. To Know What to Inspect After Disassembling of Gas Turbine Engine . During Removal – Rear Compressor Housing is being Removed First Then Followed by Front Compressor Housing. Front Compressor Housing is Reinstall First and Followed by Rear Compressor Housing . To Differentiate Between Gas Turbine Engine and Reciprocating Engine Overhauling Procedures . To Distinguish between Disassembling and Reassembling Procedures Etc. During Installation – The Other Way Around . What Clearance or Reading need to be Taken . Disassembly: 1) Cooler Assembly Figure 1: Removal of Cooler Assembly 2) Accessory Gearbox Assembly Figure 2: Removal of Accessory of Gear Box . b: Compressor Stator Vanes that Been Removed .a: Compressor Housing without Stator Vanes Figure 4.3) Front & Rear Compressor Housing Figure 3:Removal of Front & Rear Housing Assembly 4) Front & Rear Compressor Stator Vanes: Figure 4.

Disassembly. lifting and fitting it slowly and simultaneously . Compressor Housing need to be recoated as corrosive may form on exposed surface . Somehow we managed to disassemble the whole Compressor Housing . So We had to repeat . We were required to use Jack Screw as the Rear Compressor Housing was very difficult to remove . Overall . We had a hard time of reassembling the compressor housing . . most of the compressor stator vanes had dent and blunted on the leading edge . We have encounter several problems on disassembling and putting it together into one piece. Trying it to fit it in using mallet was the wrong way as it would create further damage or initiate any crack to elongated . Inspection & Reassembling of Gas Turbine Engine JE-34WE-36 was successfully completed with the help of our lecturer. All of the fasteners need to be replaced . On routine inspection. Front Compressor Housing Fasteners Hole wont matched with Cooler Assembly . We found that the engine can only for practical or maintenance purposes as it is no longer serviceable for operation. Some of the fasteners thread were already worn . Dye Penetrant Inspection were skipped as unavailability of the material in the workshop.
