INSTALLATION
1. Install oil strainer.
2. Install oil pan.
a. Use a scraper to remove all traces of liquid gasket from mating
surfaces.
IAlso remove traces of liquid gasket from mating surface of cyl-
inder block, front cover.
IRemove old liquid gasket from the bolt hole and thread.
b. Apply a continuous bead of liquid gasket to mating surface of
oil pan.
IUse Genuine Liquid Gasket or equivalent.
IApply liquid gasket to the groove on the mating surface.
IAllow 8 mm (0.31 in) clearance around center of bolt holes.
c. Apply liquid gasket to inner sealing surface as shown in figure.
IBe sure liquid gasket is 2.0 to 3.0 mm (0.079 to 0.188 in).
IAttaching should be done within 5 minutes after coating.
2. Tighten the mounting bolts in the order shown in the figure.
Then tighten in the same order to the torque stated.
3. The torque of the installation bolts will differ depending on posi-
tion.

REMOVAL
1. Remove the following parts.
IRadiator under side
IRadiator shroud
ICooling fan
IChain cover front side
IA/T cooler hose (Disconnect)
IVacuum hose
IIntercooler cover (When removing vacuum tank)
2. Remove the installation bolts and pull the vacuum pump from
the engine front directly.
3. If it is difficult to remove from the spline shaft connection, tap
lightly with a plastic hammer.

EM-24

INSPECTION
1. Remove the vacuum hose. Connect the vacuum gauge through
the 3-way connector. Otherwise, remove the welch valve of the
vacuum pipe and attach the vacuum gauge directly. (The illus-
tration shows the second method.)
IRemove an appropriate part to measure the vacuum pump load
pressure directly and install the vacuum gauge. Refer to the
figure.
2. Start the engine, and measure the load pressure with the
engine idling.
Vacuum pressure:
Standard
þ93.3 to þ101.3 kPa (þ933 to þ1,013 mbar, þ700
to þ760 mmHg, þ27.56 to þ29.92 inHg)
3. If outside the standard value, make sure that there is no intake
of air within the circuit and measure again.
4. Replace the vacuum pump if still outside the standard value.
INSTALLATION
IInstall in the reverse order of removal.

Removal and Installation
CAUTION:
As the internal mechanism of the idler gear must first of all,
and always, be set by a bolt when removing the timing chain
before removing the fuel injection pump and timing gear, fol-
low the procedures on EM-38, ªRemoval of timing chain after
setting idler gearº, ªElectronic controlled fuel injection pumpº.
IThis chapter will deal with the summary of removing the timing
chain before removing the camshaft and cylinder head.
Removal
1. Remove the following parts.
IEngine cover
IIntercooler
IAir inlet pipe
IThrottle body
IRocker cover
ISpill tube
ICoolant (Drain)
IRadiator upper hose
IWater outlet
IRadiator shroud
ICooling fan
IAuxiliary belt
IVacuum pipe
IVacuum pump

2. Move the following parts.
ITDC sensor harness
IPower steering oil pump
3. Remove the chain cover.
IRemove the holding bolts A to C shown in the figure.
CAUTION:
While the chain cover is removed, be careful not to allow entry
of dust or foreign objects.
4. Set the No. 1 cylinder to the TDC.
1) Turn the crankshaft pulley clockwise, and match the timing
indicator of the gear case to the timing mark of the crankshaft
pulley.
2) Make sure that the cam sprocket match mark is in the position
shown in the figure.
IIf the match mark is not in position, turn the crankshaft pulley
once more and position it.
IWhen removing at No. 1 cylinder TDC, each sprocket and chain
is fitted using the match mark, therefore there is no need to
apply any match marks beforehand.
5. Remove the chain tensioner.
1) Loosen upper and lower holding bolts.
2) Holding the chain tensioner in your hand, remove the upper
holding bolt and release the spring tension.
3) Remove the lower holding bolt, then remove the chain ten-
sioner.
IThe chain tensioner does not have a mechanism which pre-
vents the ejection of the plunger. (It does have a mechanism
which prevents the plunger from returning.)
CAUTION:
Be careful not to drop the plunger and spring.

6. Remove the timing chain slack guide.
7. Remove the timing chain with cam sprocket.
ILoosen the cam sprocket holding bolt by fixing the hexagonal
portion of the intake manifold side camshaft with a spanner, etc.
IIf the spill tube is not removed, fix the hexagonal portion of the
exhaust manifold side camshaft.
CAUTION:
Do not loosen the holding bolt by using the tension of the
chain.
8. Remove the timing chain tension guide.
Installation
1. Install the timing chain tension guide.
2. Install the cam sprocket and the timing chain together.
IInstall by aligning the sprocket and timing chain match marks.
ITighten the cam sprocket holding bolt by fixing the hexagonal
portion of the camshaft.
CAUTION:
Do not tighten in the holding bolt using the tension of the
chain.
3. Install the timing chain slack guide.
CAUTION:
When the holding bolt is tightened to the specified torque,
there is a gap between the guide and bolt. Do not over-tighten.
4. Install the chain tensioner.
1) With the chain tensioner in the position shown in the figure (with
the plunger on the outer side), temporarily tighten the holding
bolt.
2) Press the plunger into the tensioner body while pressing on the
clips which prevent the plunger from returning.
3) Install the upper side holding bolt while holding the plunger
down with your finger and rotating it 180 degrees.
4) Tighten the holding bolt to the specified torque.
5. Install the chain cover.
1) Before installing chain cover, remove all traces of liquid gasket
from mating surface using a scraper.
2) Apply a continuous bead of liquid gasket to chain cover.
IUse Genuine Liquid Gasket or equivalent.
a. Coat of liquid gasket should be maintained within 2.0 to 3.0
mm (0.079 to 0.118 in) dia. range.
b. Attach chain cover to gear case within 5 minutes after
coating.
c. Wait at least 30 minutes before refilling engine oil or start-
ing engine.
