The
starter motor is rated as 2.0 kW and is a Denso level three sealed unit. It is a
P76S type starter motor and is of conventional design with the motor in line and
the drive pinion and solenoid mounted above. Each starter motor is of the
pre-engaged type and comprises of a series wound motor, an overrunning clutch
and an integral solenoid. This starter incorporates labyrinth breathing tubes to
help with sealing and drainage.
The starter solenoid is energised by a
signal from the ECM when the ignition switch is moved to the crank position.
When engine cranking is requested, the ECM checks that a valid key code has been
received before granting the crank request. The power for starter operation is
supplied on a substantial single cable connected direct from the battery
positive terminal. The cable is connected to the solenoid via a copper threaded
stud and secured with a nut.
The starter motor is located on the rear RH
side of the engine block and protrudes through an aperture to drive the flywheel
via a ring gear. The motor is secured to the cylinder block by two bolts and to
the ladder frame by four bolts and a support bracket. The bracket provides
crucial support for the starter motor and must not be omitted when installing or
reinstalling the unit.
