NOTE
The manual operation of the fuel injection pump elements differs from one type of engine to another.
c.
Rotate the crankshaft until the air is evacuated or until the pressure has built up.
d.
To check a pressure relief valve, generate a pressure of 2205 psi (150 bar). The indicator of the pressure gauge
may not drop back more than 147 psi (10 bar) during a minute.
e.
Generate a pressure peak of 5145 psi (350 bar). This must be clearly indicated by the pressure gauge.
f.
A faulty injection pump should be replaced or repaired by specialists.
CAUTION
Any time the fuel injection pump has been removed, the following operational check must be
performed.
g.
Operational Check.
1.
With HP hand pump still attached, turn the engine over until the injector has a free flow of fuel.
2.
Push the stop lever to the OFF position (without run solenoid in place, it will be in the RUN position).
3.
Fuel should stop flowing. If not, do not start unit. Locate problem.
4.
Remove oil bath air cleaner assembly.
5.
Locate a board or tool box tray that will fit securely over the intake. Place it close to the unit in the event of a
runaway engine (uncontrollable engine speed) to seal off the air intake to the engine.
6.
Perform operator's PMCS and start the unit.
7.
Set engine idle speed and full throttle speed with the two adjusting screws under the throttle arm. Set to engine
manufacturer's specifications.
8.
Adjust fuel amount so when the engine is throttled from idle to full speed, there should be a light amount of black
smoke and then clear up upon reaching full throttle.
