Fill engine crankcase with oil specified in “Engine break-in oil”.
Time Load Engine Speed Remarks 5 minutes No load 800 rpm Check oil pressure, 5 minutes No load 1500 to 2300 rpm coolant temperature 10 minutes 1/4 load 2000 rpm to rated speed and check for leakages 15 minutes 1/2 load 2000 rpm to rated speed 15 minutes 1/2 to 3/4 load 2000 rpm to rated speed 10 minutes 3/4 to full load Rated speed After break-in, run the engine for 1 or 2 minutes at During the first 100 hours of operation, avoid 1500 rpm, no load, before shutting it off. Check and overloading, excessive idling and no-load operation. reset the valve clearances. After 100 hours, drain the crankcase oil and change the oil filter. Fill the crankcase with oil of the specified NOTE:
It is not necessary to retorque the cylinder viscosity. head cap screws once the engine is broken in. CD,3274,G210,2 -19-01FEB94 210 2
