DE08TS Diesel Engines Maintenance
Fuel injection pump
1. Install the injection pump bracket in the cylinder
block.
2. After measuring the amount of run-out with an
alignment setting jig, disassemble the bracket,
adjust the shims, then reassemble it.
3. Mount the top/bottom adjusting shims in the brack-
et and then mount the fuel injection pump.
4. Tighten the fixing bolts in a diagonal sequence to
specified torque.
<Injection Timing Adjustment>
5. Bring the piston of #1 cylinder to the compression
TDC (OT) by turning the crankshaft. Again, turn
60° in the reverse direction of engine rotation.
6. Disassemble the fuel injection pipe that connect
the fuel injection pump and #1 injection nozzle.
7. Disassemble the fuel injection pump delivery valve
holder, and after removing the valve and valve
spring, again assemble the valve holder and then,
on it assemble the pipe of “U” shape on it.
8. Operating the priming pump of supply pump, turn
the crankshaft slowly in the direction of engine
rotation until the fuel will drop at the rate of a drop
for 6 ~ 8 sec.
9. Confirm then whether the indication point at the
flywheel housing inspection hole and the engraved
specified injection angle are coincided or not, and
if the injection timing is not correct, adjust as fol-
lows.
a. As above adjusting method, Please coincide
the indication point( ) at the flywheel housing’s
inspection hole with the flywheel’s inspection
angle.
Fuel injection timing : BTDC 9˚
b. Loosen the drive gear fixing bolt of injection
pump a bit.
c. After turning slowly the coupling of injection
pump until the fuel will drop from #1 plunger at
the rate of a drop for 6 ~ 8 sec., tighten the dri-
ving gear fixing bolt of fuel pump.
