Fuel Gauge Unit
Removal and Installation
As for removal and installation of the Fuel Gauge Unit,
refer to “Fuel Tank" of this section 6C as the fuel gauge
unit is combined with the fuel pump and sende
r
assembly.

STARTING AND CHARGING SYSTEM 6D3-5



Inspection and Repair
Repair or replace necessary parts if extreme wear or damage
is found during inspection.
Armature
Check for continuity between commutator and segment.
Replace commutator if there is no continuity (i.e.,
disconnected).



Check for continuity between commutator and shaft.
Also, check for continuity between commutator and armature
core, armature core and shaft. Replace commutator if there is
continuity (i.e., internally grounded).




Brush
Measure the length of brush.
Replace with a new one, if it is below the limit.
Brush Holder
Check for continuity between brush holder (+) (4) and base (-).
Replace, if there is continuity (i.e., insulation is broken).




Magnetic Switch
Check for continuity of shunt coil between terminals S and M.
Replace, if there is no continuity (i.e., coil is disconnected).




Continuity of Series Coil
Check for continuity between terminals S and M.
Replace, if there is no continuity (i.e., coil is disconnected).

fan.

4. Replacing the brushes (inbuilt regulator)
Check the brushes for length, this is measured from the brush
holder to the end of the brush along it's centre line. Also
inspect for any sideways wear. If worn replace both brushes.
The minimum length is 3.8mm. Inspect the brush springs for
signs of corrosion or loss of tension or uneven tension.

Replacing the brushes, using a soldering iron apply heat to the
soldered joints on the rear of the brush holder of the regulator,
using a small lever prise up the retaining tabs to release the
brush lead and spring. Thread the new brush lead up the
brush holder along with the spring, pull the lead through the
tabs until the brush is protruding 12mm from the holder.
Bend down the tabs and solder the brush lead taking care not
to allow the solder to run up the lead which will reduce
flexibility. Use 60/40 resin cored solder.

5. Ball bearing
Please note the bearings used in this KCA generator are a
high
tolerance type, only fully sealed bearings of the same
specification are to be used as replacements. It is
recommended that the bearings be replaced during the
reconditioning process to restore the unit to original
specification.








6. Regulator
The regulator can only be tested when fitted into an altenator.

Warning: do not reverse"S" and "L" connections or put 12
volt supply to "L" terminal, this connection must not be
used as a supply source other than to supply the
requirements of the warning lamp 2(watts).
Such action will destroy the regulator warning lamp
circuit.

For test voltages refer to Generator output testing section.
See also additional information on regulator function earlier in
this instruction.

DIAGNOSTIC TROUBLE CODE (DTC) P1693
TACHOMETER OUTPUT LOW VOLTAGE
Condition for setting the DTC and action taken when the DTC sets
Circuit Description
Based on the information from the Crank Position
Sensor (CKP), X58 reference signal is generated at
each rotation of the crankshaft.
Engine Control Module (ECM) converts X58 reference
signal into the square wave signal which is used to drive
the pulse generator of the tachometer.
When the wave length of the output signal is long, the
tacho meter indicates the engine speed is low, and vise
versa.
This malfunction detects a low impedance short toground or open contact on the Tacho output, the
Diagnostic Trouble Code P1693 will be set.
Diagnostic Aids
Poor connections or a damaged harness - Inspect
the harness connections for: backed out terminals,
imprope, mating or damaged terminals. Also check
for open circuit, short to ground, and short to voltage.
This malfunction detects a low impedance short to
ground or open contact on the ECM out put circuit.

MSG MODEL 7B-25
INSPECTION AND REPAIR

Make the necessary adjustments, repairs, and part replacements if excessive wear or damage is discovered during
inspection.






SHIFT ARM THICKNESS
Use a micrometer to measure the shift arm thickness.
If the measured value is less than the specified limit, the shift
arm must be replaced.
Shift Arm Thickness mm(in)
Standard Limit
1st-2nd 9.6-9.8 (0.378-0.386) 9.0 (0.354)
3rd-4th 6.95-7.2 (0.273-0.283) 6.5 (0.256)
Rev.-5th 6.8-6.9 (0.268-0.272) 6.3 (0.248)





DETENT SPRING FREE LENGTH
Use a venier caliper to measure the detent spring free length.
If the measured value is less than the specified limit, the
detent spring must be replaced.
Detent Spring Free Length mm(in)
Standard Limit
25.6 (1.01) 23.6 (0.93)





DETENT SPRING TENSION
Use a spring tester to measure the valve spring tension.
If the measured value is less than the specified limit, the valve
spring must be replaced.
Valve Spring Tension N(kg/lb)
Compressed
Height mm(in)Standard Limit
22.1 (0.870)61.8-65.7
(6.3-6.7/13.9-14.8)55.9

BLOCK RING AND DOG TEETH
CLEARANCE
Use a thickness gauge to measure the clearance between the
block ring and the dog teeth.
If the measured value exceeds the specified limit, the block
ring must be replaced.
Block Ring and Dog Teeth Clearance mm(in)
Standard Limit
1st,2nd 2.0 (0.078) 1.3 (0.051)
