AUTO-TENSIONER CHECK

M1111003001760

OPERATION CHECK

1. Turn OFF the engine, then check to see that the drive belt is

not protruding from the pulley width of the auto-tensioner.

2. Remove the drive belt. (Refer to

P.11C-23

).

3. Securely insert the spindle handle or ratchet handle with a

17 mm (11/16-inch) socket into the hexagonal boss of the
auto tensioner. Turn the auto-tensioner slowly to the left and
right to check and see that there is no binding or noise.

4. If there are any problems in the procedure 1 or 3, replace

the auto-tensioner. (Refer to

P.11C-55

).

5. Install the drive belt. (Refer to

P.11C-23

).

POWER STEERING OIL PUMP DRIVE BELT
TENSION CHECK

M1111001100337

NOTE:

.

•

An elastic stretch-type belt is used for the power steering oil
pump drive, therefore, the tension adjustment is not neces-
sary.

•

Perform the power steering oil pump drive belt tension
check according to the following procedures.

.

<WHEN THE VIBRATION FREQUENCY IS
MEASURED: RECOMMENDATION>

Required Special Tools:

• MB992080: Belt Tension Meter Set

• MB992081: Belt Tension Meter

• MB992082: Microphone Assembly

CAUTION

• When measuring the vibration frequency, make sure

that the engine is cold.

• Measure the vibration frequency after turning the

crankshaft clockwise one turn or more.

1. Connect the special tool MB992082 to the special tool

MB992081 of the special tool MB992080.

2. Press the "POWER" button to turn on the power supply.
3. Press number key 1. Check to ensure that "No. 01" appears

on the upper left of the display and that the following
numeric values are displayed for individual items (M, W, and
S):
M 000.9 g/m
W 010.0 mm/R
S 0100 mm
If numeric values have not been entered (new tool), set
them according to the belt specifications as shown below.
Once you set them, you do not have to set them again. The
settings remain undeleted even after battery replacement.

NOTE: This operation is to temporarily set the preset data
such as the belt specifications, because if the measurement
is taken without input of the belt specifications, conversion to
tension value (N) cannot be made, resulting in judgment of
error.

<Setting procedure>

(1) Press down the "MASS" button till the belt mass select

display appears.

(2) Press the "UP" or "DOWN" button to select "01 1.5GT

0.9" and press the "MEASURE" button to decide it.
Check to ensure that "M 000.9 g/m" is displayed.

(3) Press the "WIDTH" button to change to the belt width

input display.

(4) Press number keys 0, 1, 0, and 0 sequentially, and press

the "SELECT" button to apply them. Check to ensure that
"W 010.0 mm/R" appears on the display.

(5) Press the "SPAN" button to change to the span length

input display.

(6) Press number keys 0, 1, 0, and 0 sequentially, and press

the "SELECT" button to apply them. Check to ensure that
"S 0100 mm" appears on the display.

4. Press "Hz" button twice to change the display to the

frequency display (Hz).

CAUTION

• Do not allow any contaminants such as water or oil to

get onto the microphone.

• If strong gusts of wind blow against the microphone or

if there are any loud sources of noise nearby, the val-
ues measured by the microphone may not correspond
to actual values.

• If the microphone is touching the belt while the mea-

surement is being made, the values measured by the
microphone may not correspond to actual values.

• Do not take the measurement while the vehicle's engine

is running.

5. Hold the special tool MB992080 to the middle of the power

steering oil pump drive belt between the pulleys (at the place
indicated by arrow), approximately 10

− 15 mm (0.4 − 0.59

inch) away from the rear surface of the power steering oil
pump drive belt so that it is perpendicular to the power
steering oil pump drive belt (within an angle of

± 15

degrees).

6. Press the "MEASURE" button.
7. Gently tap the middle of the power steering oil pump drive

belt between the pulleys (the place indicated by the arrow)
with your finger as shown in the illustration, and measure
that the vibration frequency of the power steering oil pump
drive belt is within the standard value.

Standard value: 119

− 225 Hz

NOTE: To take the measurement repeatedly, fillip the power
steering oil pump drive belt again.

8. After the completion of the measurement, press and hold

the "POWER" button to turn off the power supply.

9. If not within the standard value, replace the power steering

oil pump drive belt (Refer to

P.11C-23

).

.

<WHEN THE DEFLECTION IS MEASURED>

CAUTION

• When measuring the flexure, make sure that the engine

is cold.

• Measure the flexure after turning the crankshaft clock-

wise one turn or more.

Apply approximately 100 N (22 pound) of force to the middle of
the power steering oil pump drive belt between the pulleys (at
the place indicated by the arrow) and check that the amount of
deflection is within the standard value.

Standard value (Reference): 8.5

− 18.3 mm (0.33 − 0.72

inch)

POWER STEERING OIL PUMP DRIVE BELT
INSPECTION

M1112009800032

1. Check the every part of power steering oil pump drive belt

for damage including cracks or delamination in detail by a
visual inspection or touching.

2. If there is the damage, replace the power steering oil drive

belt with a new one.

ROCKER ARM PISTON OPERATION CHECK

M1111051000539

1. Remove all of the ignition coils.
2. Remove the rocker cover.

3. Remove the engine oil control valve.
4. Remove the oil pipe.
5. Turn the crankshaft clockwise until the notch on the

crankshaft pulley is lined up with the "T" mark on the lower
cover of timing belt.

6. The rocker arm piston operation check can be performed on

rocker arms indicated by white arrow mark when the No. 1
cylinder piston is at the top dead center on the compression
stroke, and on rocker arms indicated by black arrow mark
when the No. 4 cylinder piston is at the top dead center on
the compression stroke.
NOTE: If the rocker arm of No. 6 cylinder at the intake side
is moved up and down and the rocker arm is moved, No. 1
cylinder is at top dead center on compression stroke. If the
rocker arm of No. 6 cylinder at the intake side is moved up
and down and the rocker arm is not moved, No. 4 cylinder is
at top dead center on compression stroke.
