During manufacture only the best possible materials are used and all machined parts are finished to a very high standard but it is still necessary to allow the moving parts to “break-in” 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. The general rules are as follows.
Speed limits
initial 800 km (500 miles): below 7 000 r/min
up to 1 600 km (1 000 miles): below 10 500 r/min
over 1 600 km (1 000 miles): below 13 750 r/min
