Fuel system
8
- Proceed slowly during the compression phase. The fuel that flows
from tube 2 will tend to diminish.
9 - Stop as soon as it creases to drip (one drop of fuel every 30-40
seconds is tolerated).
10 - This is the static injection lead.
11
- Use a tape measure from above the flywheel to measure the
distance between the fixed TDC reference
A
fig. 164 on the
crankcase and the TDC reference point C
on the flywheel.
12
- Compare the value found in the "Conversion table from millimetres
into degrees" to find the advance degrees.
13
- If the value found does not match the specified value (see "Injec
tion advance specified value" table), replace the pad below the
injection pump (fig. 165)
Static injection timing
1 - Disconnect the pipe from injection pump outlet 1 .
2 - In its place, assemble a clear nylon hose 2
as shown in the figure.
3 - Insert a metal wire, protruding about 10 mm, into the hose to allow
an easier check of fuel leaks.
4 - Connect the injection pump intake 3 with a hose 4 to an auxiliary
tank placed at about 50 cm higher than injection pump.
5 - Fill the tank with the fuel
6
- Set the flow governor lever of the injection pump in the stop
position and lock it there.
7
- Turn the flywheel in the engine rotation direction.
Injection pump non-return valve
In the exhaust union screw there is a non-return valve. The purpose of
this valve is to improve the injection phase by expelling the air in the
fuel and preventing it from being sucked in by the pump during the in-
take phase. This also ensures that the engine stops promptly as soon
as the stopping device is activated by means of the solenoid valve.
