Pinion
1) Check by hand to see if the pinion rotates smoothly
in the dirve direction, or if it is locked when it is
rotated reversely.
If not, replace the pinion.
Yoke assembly
1) Check the magnet inside the yoke.
Replace the yoke assembly if it is broken.
REASSEMBLY
To install, follow the removal steps in the reverse order,
noting the following points:
Grease application places
1) Gears in reduction gear
2) Shift lever operating portion
3) Sliding potion of pinion
4) Plunger sliding portion of magnetic switch
Pinion jump-out dimension
1) Connect the (+) cable of battery to terminal S and
the (–) cable to terminal M. Turn the switch on, and
measure pinion travel dimension “L” in thrust
direction from the jump-out position.
In measuring the dimension, pull the pinion out a little in
the arrow direction.
Dimension L: 0.3 – 1.5 mm (0.01 – 0.06 in)If the measured value is out of standard, adjust the of
shims.

Rectifier Assembly
1. Measure the resistance between each diode
terminal and aluminum diode fin in forward and
reverse directions with the connection of the tester
leads switched. The diodes are normal if resistance
is nearly zero ohms in one direction and is infinitely
high in the other direction.
2. If a diode has no resistance or equal resistance in
both directions, it is defective and should be
replaced together with the holder.
IC Regulator Assembly
Connect a variable resistor, two 12V batteries, a fixed
resistor, and a voltmeter to the IC regulator as shown in
illustration.
a. Measuring equipment specifications
1. Fixed resistor (R1) : 10 Ohms / 3W
2. Variable resistor (Rv) : 0 – 300 Ohms / 12W
3. Batteries (BAT1, BAT2) : 12V (2 Batteries)
4. DC voltmeter : 0 – 50V / 0.5 steps (4 Check points)
b. Measuring procedure
1. Measure the voltage “V1” across the first battery
(BAT1). If the reading is between 10 and 13 volts,
the battery is normal.
2. Measure the voltage “V3” across both the batteries
(BAT1, BAT2). If the reading is between 20 and 26
bolts, the batteries are normal.
3. Gradually increase the resistance of the variable
resistor from zero. Measure the voltage “V2” (the
voltage across the F and E terminals).
Check to see that the voltage across “V1” changes
at this time. If there is no change, the voltage
regulator is faulty and must be replaced.
4. Measure the voltage at “V4” (the voltage across the
variable resistor center tap and terminal E with the
variable resistor resistance held constant). The
measure voltage should be within the specified
(14.4 ± 0.3 volts) limits. If it is not, the regulator
must be replaced.
Reassembly
To reassemble, follow the disassembly steps in the
reverse order, noting the following points:
NOTE:
1) Never make battery connections with polarities
reversed, or battery will be shorted via the diodes.
This will cause damage to the diodes.
2) Do not connect generator B terminal to ground; it is
connected directly to the battery.
This cable will burn if it is connected to ground.
3) Make sure to disconnect the positive (+) terminal of
the battery when quick-charging battery.
Diodes may be damaged due to abnormal pulse
voltage generated by the quick charger.
4) When reassembling the front section to rear
section, insert a stiff wire into hole in the rear face
of the rear cover from the outboard side to support
the brush in raised position, then insert the front
section to which rotor is assembled.
5) Reassemble parts carefully to be sure they fit into
their original position, paying attention to the
insulated portions.
6) Wipe insulating tubes, washers and plates clean
and install them in position carefully to avoid getting
oil or grease on them.

Installation
To install, follow the removal steps in the reverse order,
noting the following points:
Adjustment of select lever and control rod
1. Place the vehicle on a level surface.
NOTE: If the vehicle is not on level surface, the shift
select cable set positions will vary with the movement of
engine. To prevent possible misadjustment of the cable,
the vehicle must be placed on a level surface.
2. Install the shift control rod (1) to the transmission
select lever (2), and then place the lever in the “N”
position.
3. Set select lever in the “N” position.
4. Push select lever forward (“R” position side) and
