Clutch Disc
INSPECTION
Check clutch disc for wear of facing.
Wear limit of facing surface to rivet head:
0.3 mm (0.012 in)
+Check clutch disc for backlash of spline and runout of facing.
Maximum backlash of spline (at outer edge of disc):
Model 240
1.0 mm (0.039 in)
Runout limit:
Model 240
0.7 mm (0.028 in)
Distance of runout check point (from hub center):
Model 240
115.0 mm (4.53 in)
+Check clutch disc for burns, discoloration or oil or grease leak-
age. Replace if necessary.
INSTALLATION
+Apply recommended grease to contact surface of spline por-
tion.
Too much lubricant might cause clutch disc facing damage.

PRECAUTIONS AND PREPARATION
EC-2

Description
In this system, blow-by gas is sucked into the air inlet pipe through
the control valve after oil separation by oil separator in the rocker
cover.
Inspection
BLOW-BY CONTROL VALVE
Check control valve for clogging and abnormalities.
VENTILATION HOSE
1. Check hoses and hose connections for leaks.
2. Disconnect all hoses and clean with compressed air.
If any hose cannot be freed of obstructions, replace.

Inspection (No.2-4nozzles)
Thoroughly clean all disassembled parts with fresh kerosene or
solvent.
+If nozzle needle is damaged or fused, replace nozzle assem-
bly with a new one.
+If end of nozzle needle is seized or excessively discolored,
replace nozzle assembly.
+Check nozzle body and distance piece for proper contact. If
excessively worn or damaged, replace nozzle assembly or dis-
tance piece.
+Check distance piece and nozzle holder for proper contact. If
excessively worn or damaged, replace distance piece or nozzle
holder.
+Check nozzle spring for excessive wear or damage. If exces-
sively worn or damaged, replace it with a new spring.
Cleaning (No.2-4nozzles)
a. Do not touch the nozzle mating surface with your ®ngers.
b. To wash the nozzles, use a wooden stick and brass brush
with clean diesel fuel.
1. Remove any carbon from exterior of nozzle body (except wrap-
ping angle portion) by using Tool.
2. Clean oil sump of nozzle body using Tool.
3. Clean nozzle seat by using Tool.
This job should be performed with extra precautions, since
efficiency of nozzle depends greatly on a good nozzle seat.

Camshaft Position Sensor (CMPS) (PUMP)
The camshaft position sensor (PUMP) is located on the electronic
fuel injection pump.
The sensor consists of a permanent magnet, core and coil.
When engine is running, gap between sensor and drive shaft rotat-
ing plate will periodically change. Permeability near the sensor also
changes.
Due to the permeability change, the magnetic ¯ux near the core is
changed. Therefore, the voltage signal generated in the coil is
changed.
The ECM receives the voltage signal (6 pulses/2 engine revolu-
tions).
These signals are used for tachometer indication.
CONSULT REFERENCE VALUE IN DATA MONITOR MODE
Remarks: Speci®cation data are reference values.
MONITOR ITEM CONDITION SPECIFICATION
CKPSzRPM (REF)+Tachometer: Connect
+Run engine and compare tachometer indication with the CONSULT
value.Almost the same speed as the
CONSULT value.
