NOTICE:
Under no circumstances should
the starting motor and fuel pump
be used to prime the fuel filter.
Prolonged used of the starting motor
and fuel pump to prime the fuel
system can result in damage to the
starter, fuel pump and injectors and
cause erratic running of the engine
due to the amount of air in the fuel
lines and filter.
1. Disconnect the CMP (camshaft
position sensor) to prevent the
engine from starting. The CMP
is installed on the front cover
of the engine between the water
pump pulley and the fan pulley.
See Figure 1.
2. Operate the manual primer pump
on the filter header until the
primer pump is hard to depress.
See Figure 25.
3. Crank the engine three times for
15 seconds each. Reapply the
primer pump after each crank
cycle.
4. Once the primer pump is hard to
depress (usually three crank and
hand prime cycles), reconnect the
CMP.

SERIES 40 ENGINE OPERATOR'S GUIDE
Diesel engine exhaust and some
of its constituents are known to
the State of California to cause
cancer, birth defects, and other
reproductive harm.
□ Always start and operate an
engine in a well ventilated
area.
□ If operating an engine in
an enclosed area, vent the
exhaust to the outside.
□ Do not modify or tamper
with the exhaust system or
emission control system.
To avoid starter damage, do not
crank the engine longer than
15 seconds at a time. Allow a
15-second starter cool down interval
between starting attempts.
5. Start the engine and check for
leaks. Shut down the engine.
Correct any leaks with the engine
off.
