7.5 ENGINE AND PROPELLER
The PA-28- 161 is powered by a four cylinder, direct drive, horizontally opposed engine rated at 160 H P at
2700 RPM. It is equipped with a starter, a 60 amp 14 volt alternator, a shielded ignition, two magnetos, vacuum
pump drive, a fuel pump, a wetted polyurethane foam induction air filter.
The engine compartment is accessible for inspection through top-hinged side panels on either side of the
engine cowlings. The engine cowlings are cantilever structures attached at the fire wall The engine mounts are
constructed of steel tubing, and dynafocal mounts are provided to reduce vibration.
The exhaust system is constructed of stainless steel and incorporates dual mufflers with heater shrouds to
supply heated air for the cabin, the defroster system and the carburetor deicing system.
An oil cooler is located on the left rear of the engine mounted to the engine baffling. Engine cooling air,
which is picked up in the nose section of the engine cowling and carried through the baffling, is utilized on the left
side for the oil cooler. A winterization plate is provided to restrict air during winter operation (refer to paragraph
8.29).
Engine air enters on either side of the propeller through openings in a nose cowling and is carried through
the engine baffling around the engine and oil cooler. Air for the muffler shroud is also picked up from the nose
cowling and carried through a duct to the shroud. Carburetor induction air enters a chin scoop on the lower right
cowling and is passed through a wetted polyurethane filter to the carburetor air box. Heated air enters the
carburetor air box through a hose connected to the heater shroud.
A fixed pitch propeller is installed as standard equipment. The propeller has a 74 inch diameter with a 58 or
60 inch pitch. The pitch is determined at 75% of the diameter. The propeller is made of an aluminum alloy
construction.
The pilot should read and follow the procedures recommended in the Lycoming Operator’s Manual for this
engine in order to obtain maximum engine efficiency and time between engine overhauls.
