INSPECTION
lWhen the camshaft or parts in connection with valves are
removed or replaced, and a malfunction has occurred (poor
starting, idling, or other malfunction) due to the mis adjustment
of the valve clearance, inspect as follows.
lInspect and adjust when the engine is cool (at normal tempera-
ture).
lBe careful of the intake and exhaust valve arrangement. The
valve arrangement is different from that in a normal engine.
NOTE:
The camshafts have, alternately, either an intake valve or an
exhaust valve.(Refer to illustration)
1. Drain engine coolant. Refer toCO-30, "
Changing Engine Coolant".
2. Remove charge air cooler. Refer toEM-114, "
Removal and Installation".
3. Remove air duct and air inlet pipe. Refer toEM-112, "
Removal and Installation".
4. Remove rocker cover. Refer toEM-147, "
Removal and Installation".
5. Remove vacuum pump. Refer toEM-131, "
Removal and Installation".
6. Remove injection tube and fuel injector. Refer toEM-135, "
Removal and Installation".
7. Remove secondary timing chain. Refer toEM-158, "
Removal and Installation"
Check valve clearance while engine is cold and not running.
8. Set the No. 1 piston to TDC on its compression stroke.
lTurn crankshaft pulley clockwise so that the knock pin on
camshaft LH faces straight above. (No position indicator, etc.
is provided on the crankshaft pulley.)
9. Put an alignment mark with paint, etc. on the crankshaft pulley
and on the oil pump as an angle indicator.
10. While referring to the figure, measure the valve clearance
marked in the table below.
lThe injection order is 1-3-4-2.

lMeasure the valve clearance using a fine feeler gauge when
the engine is cool (at normal temperature).
11. Set the No. 4 cylinder at TDC by rotating the crankshaft clock-
wise once.
12. While referring to the figure, measure the valve clearance
marked in the table below.
13. If the valve clearance is outside the specification, adjust as fol-
lows.
ADJUSTMENTS
lRemove the adjusting shim for parts which are outside the spec-
ified valve clearance.
1. Remove the spill tube. Refer toEM-135, "
Removal and Installa-
tion".
2. Extract the engine oil on the upper side of the cylinder head (for
theairblowinginstep7).
3. Rotate the crankshaft to face the camshaft for adjusting shims
that are to be removed upward.
4. Grip the camshaft with camshaft pliers, them using the camshaft
as a support point, push the adjusting shim downward to com-
press the valve spring.
CAUTION:
Do not damage the camshaft, cylinder head and the outer
circumference of the valve lifter.Valve clearance (Cold):
Standard:
Intake : 0.24 - 0.32 mm (0.0094 - 0.0126 in)
Exhaust : 0.26 - 0.34 mm (0.0102 - 0.0134 in)

4. Remove front chain case.
lLoosen fixing bolts in the reverse order of that shown in the
figure and remove them.
lRemove No. 6, 10 and 11 bolts with the rubber washer as
space is limited for pulling them out.
CAUTION:
lWhile front chain case is removed, cover openings to
prevent entry of foreign material into engine.
lDo not remove two mass dampers on the back of cover.
5. Set the No. 1 piston to TDC on its compression stroke.
lTurn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
showninthefigure.
lNo position indicator is provided on the crankshaft pul-
ley.
lWhen installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
supply pump sprocket may not be easy to see.
6. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with a
push pin.
b. Using a hexagon-head wrench [face to face: 5 mm, (0.20 in)
SST], remove bolts to remove chain tensioner.

PLAY INSPECTION
1. Turn steering wheel to straight-ahead position. Start engine and lightly turn steering wheel clockwise and
counter clockwise until front wheels start moving. Measure travel to starting point on circumference of
steering wheel.
2. If play is outside specifications, check following parts for proper installation: steering gear assembly, front
suspension, axles, and steering column
lCheck steering wheel for vertical, horizontal, or axial play.
lLift vehicle and check steering gear mounting bolts and nuts for looseness.
NEUTRAL POSITION INSPECTION
lAfter the wheel alignment inspection, carry out the neutral position inspection. Refer toWT-4.
lBefore removing steering wheel, check steering gear neutral position.
1. Set vehicle to straight-ahead position, and check that steering wheel is in neutral position.
2. If it is not in neutral position, remove steering wheel, and install again in properly.
3. If it is not adjusted within two teeth from center of gear, loosen tie rod lock nut. Then turn it to opposite
direction to adjust until amount of left and right becomes equal.
STEERING TORQUE CHECK
1. Stop vehicle on a dry flat paved road and apply parking brake.
2. Start engine and wait until power steering fluid warms up. Using
a preload gauge, check rotational torque of steering wheel.
3. If torque is outside specifications, check rack sliding torque and
oil pump relief pressure.
STEERING ANGLE INSPECTION
lAfter toe-in inspection, check steering angle. Place front wheels
on turning radius gauges and rear wheels on stands. Level the
vehicle. Check maximum inner and outer wheel steering angles
for LH and RH road wheels.Steering wheel play inspection standard : 0 - 35 mm (0 - 1.38 in)
Steering wheel axial endplay: : 0 mm (0 in)
Tightening torque : 140 - 160 N·m (14.2 - 16.4 kg·m,103-118 ft·lb)
Steering torque : 706 N·cm (72 kg·cm) or less
Rack sliding torque : 153 - 240N (15.5 - 24.5 kg,
34.3-54.2 lb)

lStart engine. With engine at idle, turn steering wheel from stop
to stop and measure steering angles.
lIf angles are outside specification, measure rack stroke.
lIf rack stroke is outside of specification, disassemble steering
gear to check rack stroke.
lSteering angles are not adjustable. If any of steering angles is different from specified value, check steer-
ing gear, the column and the front suspension components for wear or damage. If any abnormality exists,
replace the malfunctioning parts.
Removal and InstallationEGS0004F
REMOVAL
1. Remove air bag module. Refer toSRS-27, "DRIVER AIR BAG MODULE".
2. Remove horn connector.
3. Remove steering wheel mounting nut and paint mating marks on steering wheel body and top of column
shaft.
4. Using a steering wheel puller, remove steering wheel.
INSTALLATION
Paying attention to following items, install in the reverse order of removal.
NOTE:
lWhen reconnecting spiral cable, fix cable with a tape so that fixing case and rotating part keep aligned.
This will omit neutral position alignment procedure during spiral cable installation.
lNeutral position (refer to figure)... Gently turn spiral cable clock-
wise until it comes to the stop. Then turn it counter clockwise
(approximately 3.0 turns) until centering mark is aligned with
adjustment mark. (Service part is fixed in neutral position with
stopper. It can be installed onto steering wheel without align-
ment once stopper is removed.)
CAUTION:
lPlace steering wheel as follows: Front wheels in straight-
ahead position. R mark on the cancel claw faces down. 3
bosses align with 3 holes behind steering wheel assembly.
Check that spiral cable is placed in neutral position and that
locating pin on the left of the spiral cable is aligned with the
locating pinhole behind the steering wheel assembly.
lDo not rotate spiral cable more than necessary. Do not tighten them excessively. (The cable may
be torn off.)
lAfter installation, check system for proper operation by observing air bag warning lamp.
lIf air bag indicator indicates any abnormal condition, use self-diagnosis function or CONSULT to
reset or cancel memory.Inner wheel: 39°+1°

specification, readjust rack. If reading is still outside specifica-
tion, replace power steering gear.
24. With tie rod gear installed to gear assembly, turn pinion gear
fully to left.
25. Set dial gauge as shown in figure. Measure vertical movement
of rack when pinion is turned counterclockwise with torque of 4.9
N·m (0.5 kg·m,43in·lb). Check reading is within range specified.
If reading is outside of specification, readjust rack. If reading is
still outside of specification, replace power steering gear.
26. Position boot band on large-diameter side before installing it.
27. Apply multi-purpose grease to both large- and small- diameter
sides.
