b. At this time, make sure both intake and exhaust cam lobes of
No. 1 cylinder (top front on left bank) point outside.

If they do not point outside, turn crankshaft pulley once more.
5. Remove rear cover plate.
6. Lock the ring gear using Tool A.
CAUTION:
Do not damage the ring gear teeth, or the signal plate teeth
behind the ring gear, when setting the Tool.
7. Loosen the crankshaft pulley bolt using suitable tool.
a. Remove the crankshaft pulley from the crankshaft.

Remove the crankshaft pulley using suitable puller. Set the
bolts in the two bolt holes [M6 x 1.0 mm (0.04 in)] on the front
surface.
NOTE:
The dimension between the centers of the two bolt holes is 61
mm (2.40 in).
8. Remove the front cover.
a. Loosen and remove the bolts in the reverse of order shown.
b. Cut the liquid gasket and remove covers using Tool.

Valve Lifter Clearance
Valve Lifter Diameter

Measure diameter of valve lifter using suitable tool.
Valve Lifter Hole Diameter

Measure diameter of valve lifter hole of cylinder head using suit-
able tool.
Calculation of Valve Lifter Clearance
(Valve lifter clearance) = (valve lifter hole diameter) – (valve lifter
diameter)

If measurement is not within specification, referring to each
specification of valve lifter diameter and hole diameter, replace
either or both valve lifter and cylinder head.
INSTALLATION
1. Install valve lifters if removed.

Install removed parts in their original locations.
2. Install camshafts. Refer to the table below for identification of
right and left bank, and intake and exhaust.

Install so that dowel pin at the front of camshaft face is in the
direction shown.Standard : 33.977 - 33.987 mm (1.3377 - 1.3381 in)

Revision: August 20072004 QX56

Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-
bration Schedule.
THE ALIGNMENT PROCESS
IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to FSU-21,
"Wheelarch Height (Unladen*1 )" .
1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or
minus, Go/No Go). Do NOT use these indicators.

The alignment specifications programmed into your alignment machine that operate these indicators
may not be correct.

This may result in an ERROR.
2. Some newer alignment machines are equipped with an optional “Rolling Compensation” method to “com-
pensate” the sensors (alignment targets or head units). Do NOT use this “Rolling Compensation”
method.

Use the “Jacking Compensation” method. After installing the alignment targets or head units, raise the
vehicle and rotate the wheels 1/2 turn both ways.

See Instructions in the alignment machine you are using for more information.
CAMBER AND CASTER
1. Measure camber and caster of both the right and left wheels
with a suitable alignment gauge and adjust as necessary to
specification.
2. If outside of the specified value, adjust camber and caster using
the adjusting bolts in the front lower link.
CAUTION:
After adjusting the camber then check the toe-in.
NOTE:
Camber changes about 3' (0.11°) with each graduation of one
adjusting bolt. Refer to table below for examples of lower link
adjusting bolt effect on camber and caster.
3. Tighten the adjusting bolt nuts to specification. Refer to FSU-5, "
Components" . Camber : Refer to FSU-20, "
Wheel Alignment
(Unladen*1 )" .

CONSULT-II CHECKING SYSTEMPFP:00000
DescriptionEAS001SK

CONSULT-II is a hand-held type tester. When it is connected with a diagnostic connector equipped on the
vehicle side, it will communicate with the control unit equipped in the vehicle and then enable various
kinds of diagnostic tests.

Refer to "CONSULT-II Operator's Manual" for more information.
