WARNING
This engine has been run in and is ready for flight.
DO NOT GROUND RUN THIS ENGINE
This engine has been inhibited and the oil system drained. Before first start of new engine,
remove 1 spark plug from each head. Add the required run-in oil to sump (3.4 litres), engine must
have oil cooler fitted. Press starter to obtain oil pressure and to throw out excess inhibiting oil in
cylinders. Replace plugs. NOTE: ALL plastic bungs must be removed
Note: Heads have a 1/8 NPT plug to be unscrewed to uncover head bolt No. 5. After torquing
reset plug.
CAUTION:
Do not overtighten. Overtightening will eventually loosen fit between plug and head to the
point where it will not be secure.
Figure 7 – Head Bolt Locations
If the engine is run on the ground before flight use minimum power settings and minimum time
to avoid overheating. If the engine is to be run at more than idle power on the ground extralarge
cooling ducts and oil cooler will be required.
For the first 25 hours of operation, add 3.4 litres of Shell 100 oil. After 25 hours drain oil,
retorque cylinder head bolts to 20 ft lbs.
