1-6 GENERAL INFORMATION
BREAK-lN PROCEDURES
During manufacturing only the best possible materials are used and all machined parts are finished to a very
high standard. It is still necessary to allow the moving parts to “BREAK-lN” before subjecting the engine to
maximum stresses. The future performance and reliability of the engine depends on the care and restraint
exercised during its early life. Refer to the following break-in engine speed recommendations.
• Keep to these breake-in engine speed limits.
Break-in engine speeds
Initial 10 hours: Less than ½ throttle
• After the engine has been operated for 10 hours the engine to full throttle operation, for short periods of
time.
