GENERAL.
This chapter covers the power plants used in this airplane, and is comprised of instructions for removal and installation, minor repairs, and service.
DESCRIPTION.
O-360-A1H6 (left) and LO-360-A1H6 (right) Textron Lycoming four cylinder, horizontally opposed, engines rated at 180 horsepower each are installed. See Chapter 6, Leading Particulars, for engine operating limits.
— CAUTION —
TO ENSURE ADEQUATE OUTFLOW THROUGH OIL BREATHER TUBE ON -AIH6 ENGINES, DO NOT PERMIT CUTOUT IN SHROUD AROUND BREATHER VENT HOLES TO BECOME BLOCKED.
The -A1H6 model engines have the oil breather pipe wrapped in a sheath to decrease the probability of condensation freezing and blocking the pipe during winter operations. (Refer to Figure 71-1.)
The propellers installed are Hartzell constant speed units. (Refer to Chapter 61 for complete detail and service information.) The induction system on these engines consists of Marvel-Schebler HA-6 float type carburetors with dry type air filters.
The magnetos are Slick 4300 Series. These are installed two per engine as left and right magnetos with individual drives. The left magneto on each engine incorporates an impulse coupling to provide ignition at engine cranking speed. (Refer to Chapter 74 for detailed information.)
TROUBLESHOOTING.
Potential power plant problems are listed in Chart 7101, which includes Probable Causes and Suggested Remedies.
— WARNING —
GROUND THE MAGNETO PRIMARY CIRCUIT BEFORE PERFORMING ANY CHECKS ON THE ENGINES.
