Compressor Inlet Screens To prevent the engine from readily ingesting any items that can be drawn in the intake, a compressor inlet screen is sometimes placed across the engine air inlet at some location along the inlet duct. Engines that ... incorporate inlet screens, such as turboprops [Figure 3-28] and APUs [Figure 3-29] are not as vulnerable to FOD. The advantages and disadvantages of a screen vary. If the engine is readily subjected to internal damage, as would…

operate the engine longer than 5 hours before the first oil change. Check all oil filters and screens for evidence of sludge or plugging. Change oil every 10 hours if sludge conditions are evident. Repeat 10-hour checks until clean ... screen is noted, then change oil at recommended time intervals. 4. All turbocharged engines must be broken in and operated with ashless dispersant oil. Oil & Filter Change & Screen Cleaning One manufacturer recommends that for new, remanufactured; or newly overhauled engines…

Oil Temperature Bulbs Most oil temperature bulbs are mounted in the pressure oil screen housing. They relay an indication of engine oil inlet temperature to the oil temperature indicators mounted on the instrument panel. Temperature bulbs can be replaced ... Figure 6-25] Figure 6-23. Checking oil level with dipstick. Figure 6-24. Oil cooler. Pressure & Scavenge Oil Screens Sludge accumulates on the pressure and scavenges oil screens during engine operation. [Figure 6-26] These screens must be removed…
