8.39 CLEANING
(a) Cleaning Engine Compartment
Operating conditions and environments dictate the frequency
and methods to be observed in cleaning the airplane's engines. Salt
air and airborne pollution, for example, leave corrosive deposits
which must be washed from the engine before they are allowed to
accumulate.
For engine cleaning procedures, refer to and comply with the
Pratt and Whitney PT6A-!35 Maintenance Manual, Part No.
302142, Chapter 70.
(b) Cleaning Landing Gear
Before cleaning the landing gear, place a cover of plastic or a
similar waterproof material over the wheel and brake assembly.
(I)
Place a pan under the gear to catch waste.
(2) Spray or brush the gear with solvent or a mixture of solvent
and degreaser. To remove especially heavy dirt and grease
deposits, it may be necessary to brush areas that were
sprayed.
(3) Allow the solvent to remain on the gear from five to ten
minutes. Then rinse the gear with additional solvent and
allow it to dry.
(4) Remove the protective cover and the catch pan.
(5) Lubricate the gear in accordance with the Lubrication
Chart in the PA-31T2 Service Manual.
