Item Ispectio/Maiteace Actio REFERENCE Iitial 2000 HOUR INSPECTION 8 Ispect the spur adapter gearshaft, compressor rotor splied adapter ad associated impeller bore. 72--30--00, PARA 4.B.(2), 4.C. ad 4.E. 9 Ispect the turbie to compressor couplig, turbie splied adapter, power turbie ier shaft ad turbie shaft--to--piio gear couplig. PARA 6.A. ad 6.B. Turbie to compressor couplig is part of the turbie assembly. Not applicable for: Torquemeter gear part umber 23084248 ad subsequet Power take----off gear part umber 23084249 ad subsequet Piio gear part umber 23084247 ad subsequet. 10 Examie the power drivetrai gears. Disassembly of the gearbox is ot ecessary for this ispectio. CSL 3225 NOTES: The followig ispectios are recommeded wheever the turbie or compressor is removed i--betwee the required 2000 hour ispectio. Aytime the compressor is removed from the egie, visually ispect the aft ed of the spur adapter gearshaft for wor or damaged spies. Aytime the turbie is removed from the egie, visually ispect the splies o the followig items, turbie--to--compressor couplig, turbie splied adapter, power turbie outer shaft ad turbie shaft--to--piio gear couplig for wor or damaged splies. If splie wear or damage is observed the appropriate maiteace actio is required. (Refer to item 8 ad 9 above). Ispectio itervals must ot exceed 2000 hours.
