GENERAL
8. To remove the injection pump, first disconnect the
injection pipes and fuel feed pipe from the injection
pump. Then, remove the tie-rod cover and tie-rod.
Dismount the pump assembly. Reassembly
sequence of the pump is the reverse of
disassembly.
9. In the dusty place or when the engine is dirty,
removal of a delivery valve may cause dust to
enter into the injection pump. Under such
circumstances leave the delivery valve installed
and check injection timing using the following
procedure:
a Remove the tie-rod cover and disconnect the
tie-rod from the control rack.
b Set the control rack to a midway position in
the working range. Disconnect the injection
pipe from the No. 1 nozzle. Turn the
crankshaft gradually in the direction of normal
rotation until swelling of fuel is found at the
open end of the injection pipe. This instant is
the real injection timing, which will come
approx. 1° later than standard injection timing.
5.8 Adjusting the engine speeds
To adjust engine speed, remove the cooling fan and
install the safety cover over the fan to reduce the risk of
injury.
1. The upper limit of engine speed can be adjusted
with the HIGH-SPEED stopper bolt. This stopper
bolt has been set properly and sealed in the
factory before shipping of the engine. Never
attempt to open the seal unless it is necessary.
2. The lower limit of engine speed can be adjusted
with the LOW-SPEED stopper bolt.
3. Never remove the sealing cap unless it is
necessary to adjust the torque spring set.
4. During running of the engine for speed adjustment,
check the engine for gas leak, water leak, oil leak
and fuel leak.
