Adjusting the pinion stroke
Adjust the pinion stroke as follows:
1. Remove the starter motor, refer to page 4.
2. Screw the pivot pin (B) fully into the casting and
then slacken off one full turn and position the
marks on the head as shown.
3. Connect the solenoid to a 6V supply as shown,
which will operate the solenoid only.
4. While the solenoid is energized push the pinion
lightly, back against the yoke, to eliminate any
free play and measure the gap between the pin-
ion end face and the snap ring collar.
5. If necessary, turn the pivot pin (8) to obtain a
clearance of 0.13 to 1.14 mm (0.005 to 0.045
in).
6. Tighten the locknut to 20 Nm (15 lbf ft).
7. Install the starter motor, refer to page 4.

Testing the battery voltage under load
Test equipment
0 to 20 V dc voltmeter
NOTE :
This test can be made with the starter motor
still installed on the machine.
Do the battery voltage under load test as follows:
1.Check condition of battery or batteries, refer to
battery testing.
2. Open the hood.
3. Disconnect the wire from fuel injection pump to
prevent the engine from starting.
4. Connect the voltmeter across the terminals as
shown and with the engine fuel supply cut off,
operate the starter.
5. The voltmeter should read approximately 9 V. A
low voltage reading indicates excessive current
flow in the circuit due to low resistance.
6. Reconnect the wire to the fuel injection pump if
no further tests are required.
7. Close the hood.
