ENGINE OPERATION
58
NOTICE
New engine break-in:
• On the initial engine start-up, allow the engine to
idle for approximately 15 minutes while you check
for proper engine oil pressure, diesel fuel leaks,
engine oil leaks, coolant leaks, and for proper
operation of the indicators and/or gauges.
• During the first hour of operation, vary the engine
speed and the load on the engine. Short periods
of maximum engine speed and load are
desirable. Avoid prolonged operation at minimum
or maximum engine speeds and loads for the next
four to five hours.
• During the break-in period, carefully observe the
engine oil pressure and engine temperature.
• During the break-in period, check the engine oil
and coolant levels frequently.
NOTICE
Never engage the starter motor while the engine is
running. This may damage the starter motor pinion
and/or ring gear.
1. While the engine is running, check the gauges
for normal indications. The gauges shown in
Figure 6 and Figure 5 are provided for
illustrative purposes only.
Figure 5
Figure 6
• Tachometer (Figure 6, (1)) or (Figure 5, (1))
-Make sure the engine speed is within normal
limits.
• Engine oil pressure (Figure 6, (2)) or
(Figure 5, (3)) - Make sure the engine oil
pressure is within normal limits. See Principal
Engine Specifications on page 105.
• Engine coolant temperature (Figure 6, (3))
or (Figure 5, (2)) - Make sure the engine
coolant temperature is within normal limits.
• Hour meter - The hour meter display
(Figure 6, (4)) or (Figure 5, (4)) shows the
total number of hours the engine has run. This
is useful for planning periodic maintenance
operations. See Periodic Maintenance
Schedule on page 64.
• If any of the gauges shows an out of normal
limits condition, shut down the engine and have
the necessary repairs performed.
