CAUTION
If the lubricating oil pressure is not within
specifications,
shut
off
the
engine
immediately. Either excessively low or
excessively high oil pressure will cause
engine damage.
Engine oil pressure must be at least 69 kPa [10 psi] at
700 RPM.
Correct the problem if the oil pressure is not within
specifications.
CAUTION
Do not operate the engine at idle speed
longer than specified during engine run-in.
Excessive carbon formation will cause
damage to the engine.
Operate the engine at approximately 700 RPM for 3 to 5
minutes.
Listen for unusual noises; watch for coolant, fuel, and
lubricating oil leaks; and check for correct engine oper-
ation in general.
NOTE
Repair all leaks or component problems
before continuing the engine run-in.
Move the throttle to obtain 1,200 RPM engine speed,
and set the test load to 25 percent of the torque peak
load.
Operate the engine at this speed and load level until the
coolant temperature is 70C [160F]. Check all gauges
and record the data.
NOTE
Do not proceed to the next step until a
steady blowby reading is obtained.
