What our service work and the manufacturer documentation say about keeping this model running.
Inspect compressor and turbine condition, air filter or silencer, gas path, bearings, lubrication supply and drains. Trend boost pressure, exhaust temperature, turbocharger speed where available and vibration or noise. Clean gas-path components using only approved methods. Refer to the manufacturer documentation for the exact figure for bearing, balance, speed and clearance limits.
Carry bearing and seal service kits where onboard overhaul is permitted, filters, gaskets, locking parts, sensor components and manufacturer-approved cleaning or rotor service items.
