Control Operation
FAN CONTROL KNOB
This knob turns the fan ON and OFF, and controls fan speed.
MODE CONTROL KNOB
This knob controls the outlet air ¯ow.
TEMPERATURE CONTROL KNOB
This knob allows adjustment of the temperature of the outlet air.
RECIRCULATION (REC) SWITCH
OFF position: Outside air is drawn into the passenger compartment.
ON position: Interior air is recirculated inside the vehicle. The indicator lamp will also light.
AIR CONDITIONER SWITCH
The air conditioner switch controls the A/C system. When the switch is depressed with the fan ON, the com-
pressor will turn ON. The indicator lamp will also light.
The air conditioner cooling function operates only when the engine is running.

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

+Measure wear of 2nd and 3rd baulk rings.
a. Place baulk rings in position on synchronizer cone.
b. While holding baulk rings against synchronizer cone as far as
it will go, measure dimensions ``A'' and ``B''.
Standard:
A 0.7 - 0.9 mm (0.028 - 0.035 in)
B 0.6 - 1.1 mm (0.024 - 0.043 in)
Wear limit:
0.2 mm (0.008 in)
+If dimension ``A'' or ``B'' is smaller than the wear limit,
replace outer baulk ring, inner baulk ring and synchronizer
cone as a set.
+Measure wear of reverse baulk ring.
a. Place baulk ring in position on reverse cone.
b. While holding baulk ring against reverse cone as far as it will
go, measure dimension ``A'' with dial indicator.
Dimension ``A'':
Standard þ0.1 to 0.35 mm (þ0.0039 to 0.0138 in)
Wear limit 0.7 mm (0.028 in)
c. If dimension ``A'' is larger than the wear limit, replace baulk ring.
BEARINGS
+Make sure bearings roll freely and are free from noise, crack,
pitting or wear.
