3. Align the alignment mark (white line) on the timing
belt (1) with alignment mark on the RH bank
camshaft drive pulley (2) (on the left side as
viewed from the front of the vehicle) and put the
timing belt on the camshaft drive pulley.
Secure the belt with a double clip or equivalent
clip.

(1) Alignment Mark on Timing Belt (White line).
(2) Alignment Mark on Camshaft Drive Pulley.
(3) Alignment Mark on Cylinder Head Cover RH.
4. Align the alignment mark on the LH bank
camshaft drive pulley (2) to the alignment mark of
the cylinder head cover LH (3).
The camshaft pulley is not 1:1 with the camshafts.
It is necessary to rotate the camshaft pulley until
the camshaft lobes are in the position as shown
in the diagram on page 6A±34.
The camshaft pulley alignment mark should also
align with alignment mark on the cylinder head
cover.
It may require up to four revolutions of the cam-
shaft pulley to achieve alignment of all marks.
5. Align the alignment mark (white line) on the timing
belt (1) with the alignment mark on the LH bank
camshaft drive pulley (2).
When aligning the timing marks, use a wrench to
turn the camshaft drive pulley, then set the timing
mark between timing belt and camshaft drive
pulley and put the timing belt on the camshaft
drive pulley.
Secure the belt with a double clip or equivalent
clip.NOTE: It is recommended for easy installation that the
belt be secured with a double clip or equivalent clips after
it is installed to each pulley.

6. Install crankshaft pulley temporarily and tighten
center bolt by hand (do not use a wrench).
Turn the crankshaft pulley clockwise to give some
belt slack between the crankshaft timing pulley
and the RH bank camshaft drive pulley.
2. Install pusher and tighten bolt to the specified torque.
Torque : 25 N´m (2.5 kg´m/18 lb ft)
1. Install the pusher while pushing the tension pulley
to the belt.
2. Pull out pin from the pusher.
NOTE: When reusing the pusher, press the pusher with
approximately 100Kg to retract the rod, and insert a pin
(1.4 mm (0.055 in) piano wire).

STARTING AND CHARGING SYSTEM (6VE1 3.5L)
Charging System
General Description
The IC integral regulator charging system and its main
components are connected as shown in illustration.
The regulator is a solid state type and it is mounted along
with the brush holder assembly inside the generator
installed on the rear end cover.
The generator does not require particular maintenance
such as voltage adjustment.The rectifier connected to the stator coil has diodes to
transform AC voltage into DC voltage.
This DC voltage is connected to the output terminal of
generator.

General On±Vehicle Inspection
A basic wiring diagram is shown in the illustration. When
operating normally, the indicator bulb will come on when
the switch is turned on, and will then go out when the
engine starts. If the indicator operates abnormally, or if an
undercharged or overcharged battery condition occurs,
the following procedure may be used to diagnose the
charging system. Remember that an undercharged
battery is often caused by accessories being left on
overnight, or by a defective switch which allows a bulb,
such as a trunk or glove box light, to stay on.
Observe the following procedure:
1. Visually check belt and wiring.
2. Go to step 5. for vehicles without charge indicator
light.
3. Switch on, engine stopped, light should be on. If not,
detach harness at generator, ground ªLº terminal
lead.a. Lamp lights, replace or repair generator.
b. Lamp dose not light, locate open circuit between
grounding lead and ignition switch. Bulb may be
open.
4. Switch on, engine running at moderate speed. Light
should be off. If not, detach wiring harness at
generator.
a. If light goes off, replace or repair generator.
b. If light stays on, check for grounded ªLº terminal
wire in harness.
5. Battery undercharged or overcharged.
a. Detach wiring harness connector from generator.
b. With switch on, engine not running connect
voltmeter from ground to ªLº terminal in wiring
harness, and to ªIGº terminal. If used. Wiring
harness may connect to either ªLº or ªIGº or both.
c. Zero reading indicates open circuit between
terminal and battery. Connect as required.
