SERVICE PRECAUTION

WARNING: THIS VEHICLE HAS A SUPPLEMENTAL

RESTRAINT SYSTEM (SRS), REFER TO THE SRS

COMPONENT AND WIRING LOCATION VIEW IN

ORDER TO DETERMINE WHETHER YOU ARE

PERFORMING SERVICE ON OR NEAR THE SRS

COMPONENTS OR THE SRS WIRING. WHEN YOU

ARE PERFORMING SERVICE ON OR NEAR THE

SRS COMPONENTS OR THE SRS WIRING, REFER

TO THE SRS SERVICE INFORMATION. FAILURE TO

FOLLOW WARNINGS COULD RESULT IN

POSSIBLE AIR BAG DEPLOYMENT, PERSONAL

INJURY, OR OTHERWISE UNNEEDED SRS SYSTEM

REPAIRS.

CAUTION: Always use the correct fastener in the

proper location. When you replace a fastener, use

ONLY the exact part number for that application.

HOLDE N will call out those f asten ers th at requir e a

replacement after removal. HOLDEN will also call

out the fasteners that require thread lockers or

thread sealant. UNLESS OTHERWISE SPECIFIED,

do not use supplemental coatings (Paints , greases,

or other corrosion inhibitors ) on threaded fast eners

or fastener joint interfaces. Generally, such

coatings adversely affect the fastener torque and

the joint clamping force, and may damage the

fastener. When you install fasteners, use the

correct tightening sequence and specifications.

Following these instructions can help you avoid

damage to parts and systems.

STARTING SYSTEM

GENERAL DESCRIPTION

Cranking Circuit

The cranking system consists of a battery, starter,

starter switch, starter relay, etc. These main

components are connected.

Starter

The cranking system employs a magnetic type

reduction starter in which the motor shaft is also used as

a pinion shaft. Wh en the starter switch is turned on, the

contacts of solenoid are closed, and the armature

rotates. At the same time, the plunger is attracted, and

the pinion is pushed forward by the shift lever to mesh

with the ring gear.

Then, the ring gear runs to start the engine. When the

engine starts and the starter switch is turned off, the

plunger returns, the pinion is disengaged from the ring

gear, and th e armatur e stops rotatio n. When the eng ine

speed is higher than the pini on, the pinion id les, so that

the armature is not driven.

Replace, if there is no continuity (i.e., coil is

disconnected).

065RW017

Continuity of Contacts

With the plunger faced downward, push down the

solenoid. In this state, check for continuity between

terminals B and M. Replace, if there is no continuity

(i.e., contacts are faulty).

REASSEMBLY

To install, f ollow the remova l st eps in the reverse order,

noting the following points:

Grease application places

• Bushing in rear cover and center bracket

• Gears in reduction gear

• Shift lever operating portion

• Sliding portion of pinion

• Plunger sliding portion of solenoid

Reassembling Yoke Assembly

Before reassembly, make sure that no metallic parts

attach to the yoke assembly. Because of strong

magnetic force, hold the yoke assembly and insert it

slowly into the armature.

Torque

Torque for each part (See Torque Specifications in

this section)

Pinion Jump–out Dimension

Connect the “+" cable of battery to terminal S and the “–

" cable to terminal M. Turn the switch on, and measure

pinion travel dimension in thrust direction from the

jump–out position.

In mea suri ng the dimens io n, pul l the pini on ou t a little in

the arrow direction.

Dimension(L): 0.05 mm to 1.5 mm (0.002 in to 0.06

in)

065RS030

If the measured value is out of standard, insert dust

cover, or disassemble and adjust.

065RW019

Characteristic Test

For easily confirming the characteristics, conduct the no

load test as follows:

Rating as short as 30 seconds requires rapid testing.

Fix the starter on the test bench, and wire as shown in

illustration. When the switch is closed, the current flows

and the starter runs under no load. At this time,

measure current, voltage and speed to check if they

satisfy the standard.
