MAINTENANCE MANUAL
GENERAL.
DESCRIPTION.
The PA-32-301 is powered by a Lycoming engine of 300 horsepower. (Refer to Power Plant
Specifications in Chapter 6.) The engine is furnished with a starter. 60 ampere. 12-volt alternator. voltage
regulator. shielded ignition system. vacuum pump drive, fuel pump, fuel injector and a dry paper type
induction air filter. In the event of air stoppage through the filter an alternate air source can be opened when
selected manually by the use of a lever in the cockpit.
The exhaust system consists of three individual mufflers combined into one unit. Each set of opposing
cylinders feeds into one muffler. A heat shroud encircles the complete unit to provide heat for both the cabin
and defrosting.
The engine is provided with a constant speed propeller controlled by a governor mounted on the engine
supplying oil through the propeller shaft at various pressures.
The PA-32-301T is powered by a Lycoming engine model TIO-540-SIAD. This engine is a direct drive.
six cylinder, fuel injected, horizontally opposed, air cooled engine with top side exhaust incorporating oil jets
for internal piston cooling. The engine is furnished with a starter. 60 amperes. 12-volt alternator, voltage
