PERIODIC MAINTENANCE
MA-5

6. Install all injection nozzles with Tool and securely connect fuel
spill tube and delivery tubes.
7. Bleed air from fuel system and check for fuel leakage with
engine running.
Injection nozzle to cylinder head:
:59-69Nzm (6.0 - 7.0 kg-m, 43 - 51 ft-lb)
Spill tube nut:
:39-49Nzm (4.0 - 5.0 kg-m, 29 - 36 ft-lb)
Injection tube:
:20-25Nzm (2.2 - 2.5 kg-m, 16 - 18 ft-lb)
Checking Idle Speed
Inspection should be carried out with gears in ``Neutral'' and
with air conditioner and other electrical loads off.
1. Warm up engine until engine coolant temperature indicator
points to the middle of gauge.
2. Attach a diesel tachotester's pick-up to No. 1 fuel injection tube.
3. Race engine two or three times and check idle speed.
Idle speed:
Unit: rpm
