11.3 COOLING AIR BAFFLES
The baffles installed around the engine direct the cooling air flow to the oil cooler and to
other engine components to provide optimum engine cooling. The baffles, air inlets and
outlets and air scoops are accurately positioned to maintain engine cooling efficiency and
their removal will cause improper air circulation and engine overheating.
11.3.1
CLEANING AND INSPECTION
Engine baffles should be cleaned with a suitable solvent (Mineral Turpentine) to remove
dirt and oil. Inspect baffles for cracks, splits or damage. Replace defective parts.
11.3.2
COOLING AIR BAFFLE REMOVAL & INSTALLATION
Baffles are removed by unbolting from the engine and removing tension springs and their
attaching wires.
Reverse the preceding steps for installation.
11.3.3
REPAIR
Repair of baffles is limited to the replacement of rubber seals. Rubber seals may be
replaced by removing the existing rubber parts, rubbing back the bonding face of the
fiberglass baffles to bare glass (using 80 grit sandpaper or similar) and bonding new
rubber strips in place with 5-Minute Araldite.
11.4 ENGINE MOUNT
The engine mount is a welded assembly. Its purpose is to support the engine and attach
the engine to the airframe. The engine is attached to the mount with rubber cushions
which absorb engine vibrations.
Spaces are used to correctly align the engine. Ensure that they are correctly marked on
removal and correctly replaced on reassembly.
IMPORTANT
The engine mounts should not be repaired. If damaged, replace with a new part.
The bolts on the engine mount must only be fitted with high temperature nuts. DO
NOT USE NYLOC NUTS as the nylon insert may melt causing failure.
11.5 ENGINE FUEL SYSTEM
11.5.1
FUEL SYSTEM GENERAL
The engine is equipped with a carburettor mounted below the engine and a fuel pump at
the Starboard rear of the engine. Refer to engine Maintenance & instruction manual for
carburettor jet removal, idle adjustment and carburettor bowl cleaning procedures.
WARNING
Fuel lines within the engine compartment are fitted with fireproof sleeves. These
sleeves must not be removed.
