1999 MITSUBISHI LANCER EVOLUTION VI clock

WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component,
can lead to personal injury or death to service personnel (from inadvertent firing of the air
bag) or to the driver and passenger (from rendering the SRS inoperative).
(2) SRS components should not be subjected to heat over 93C, so remove the SRS-ECU, air
bag module and clock spring before drying or baking the vehicle after painting.
(3) Service or maintenance of any SRS component or SRS-related component must be performed
only at an authorized MITSUBISHI dealer.
(4) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP
52B – Supplemental Restraint System (SRS), before beginning any service or maintenance
of any component of the SRS or any SRS-related component.
NOTE
Section titles with asterisks (*) in the table of contents in each group indicate operations requiring warnings.

GENERAL – Precautions Before Service00-15
PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B – Supplemental Restraint System (SRS).
For safe operations, please follow the directions and heed all warnings.
(2) Always use the designated special tools and test equipment.
(3) Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
has been disconnected. Serious injury may result from unintended air bag deployment if work
is done on the SRS system immediately after the battery cable is disconnected.
(4) Never attempt to disassemble or repair the SRS components. (SRS air bag control unit, air bag
module and clock spring.) If faulty, replace it.
(5) Warnings labels must be needed when servicing and handling SRS components. Warning labels
are located in the following locations.
Sun visor
Glove box
SRS air bag control unit
Steering wheel
Steering gear and linkage
Air bag module
Clock spring
(6) Store components removed from the SRS in a clean and dry place.
The air bag module should be stored on a flat surface and placed so that the pad surface is
facing upwards.
(7) Be sure to deploy the air bag before disposing of air bag module or disposing of a vehicle equipped
with an air bag. (Refer to GROUP 52B – Air Bag Module Disposal Procedures.)
(8) Whenever you finish servicing the SRS, check the SRS warning lamp operation to make sure
that the system functions properly.
2. Observe the following when carrying out operations on place where SRS components are installed,
including operations not directly related to the SRS air bag.
(1) When removing or installing parts do not allow any impact or shock to the SRS components.
(2) SRS components should not be subjected to heat over 93C, so remove the SRS components
before drying or baking the vehicle after painting.
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.

ENGINE – Timing Belt11-22
LTIMING BELT INSTALLATION
(1) Place the exhaust side camshaft sprocket in a position
where its timing mark is one tooth offset from the timing
mark on the rocker cover in the counterclockwise direction.
NOTE
Even if the timing marks on the sprocket and the rocker
cover are brought into alignment, the exhaust camshaft
is forced back by the valve spring tension. It is stabilized
at a position one tooth before the timing mark.
(2) Align the timing mark on the intake side camshaft sprocket
with that on the rocker cover.
NOTE
Even if the timing marks on the sprocket and the cover
are brought into alignment, the intake camshaft is forced
to turn one tooth in the clockwise direction by the valve
spring tension and stabilized there.
(3) Place the timing mark on the crankshaft sprocket one
tooth this side from the mated timing mark as in the case
of the camshaft sprocket.
(4) Align the timing mark on oil pump sprocket with its mating
mark.
(5) Remove the plug on cylinder block and insert a Phillips
screwdriver (shank diameter 8 mm) through the hole
(Engine with counterbalance shafts).
If it can be inserted as deep as 60 mm or more, the
timing marks are correctly aligned. If the inserted depth
is only 20 – 25 mm, turn the oil pump sprocket one turn
and realign timing marks. Then check to ensure that the
screwdriver can be inserted 60 mm or more. Keep the
screwdriver inserted until installation of timing belt is
finished.

(6) Remove the Phillips screwdriver. Place the oil pump
sprocket in a position where its timing mark is one tooth
offset from the mated timing mark in the counterclockwise
direction.
(7) Fit the timing belt over the exhaust side camshaft sprocket,
and secure it at the illustrated position using a paper
clip.
(8) Turn the intake side camshaft sprocket as shown to a
position where its timing mark is one tooth offset from
the mated timing mark in the counterclockwise direction.
Then, fit the timing belt over the sprocket and secure
it with a paper clip.
NOTE
The intake camshaft will be turned a little clockwise by
the valve spring tension and stabilized in position even
if the belt is clipped at one tooth offset position.
(9) Check to ensure that the timing marks on the intake
camshaft sprocket side are in alignment when the exhaust
camshaft sprocket is turned clockwise to align the timing
marks.
NOTE
The timing belt span between the intake and exhaust
sprockets will have 17 cogs.
(10)Fit the timing belt over the idler pulley, oil pump sprocket
and crankshaft sprocket in this order.
NOTE
Be careful that the belt does not become slack.

(11) Fit the timing belt over the tensioner pulley.
NOTE
When fitting the timing belt over the tensioner pulley,
turn the intake side camshaft sprocket a little
counterclockwise, as this will facilitate the work.
(12)Turn the crankshaft pulley a little in the illustrated direction
to pull up the timing belt at the idler pulley side.
(13)Check to ensure that the timing marks on the crankshaft
sprocket, oil pump sprocket and exhaust camshaft
sprocket are all offset one tooth from the corresponding
timing marks in the counterclockwise direction.
(14)Using the special tool, turn the tensioner pulley in the
illustrated direction to strain the timing belt. Then, secure
the tensioner temporarily by tightening the retaining bolt
lightly.
NOTE
There must be no slack in the timing belt between the
intake and exhaust camshafts.
(15)Turn the crankshaft to align the timing mark with the mark
for No. 1 cylinder top dead center in the compression
stroke.
(16)Set the special tool as shown and screw it in up to the
position where the wire inserted in the auto-tensioner
when installing it can be moved lightly.

(17)Loosen the retaining bolt of the tensioner pulley.
Caution
Loosening the retaining bolt can cause the intake
and exhaust camshafts to turn, resulting in slackened
timing belt. Use care that the timing belt does not
come off the sprockets at this time.
(18)Pull up the slack of the timing belt by turning the tensioner
in illustrated direction using the special tool and a torque
wrench (0 – 5 Nm).
(19)From this position, turn back the tensioner until the torque
wrench reading becomes 3.5 Nm, then secure it by
tightening the retaining bolt.
(20)Remove the special tool attached in step (16).
(21)Rotate the crankshaft clockwise 2 turns. Then, leave it
intact 15 minutes.
(22)Check to see that the wire inserted when installing the
auto-tensioner can be pulled out lightly. If it can be pulled
out lightly, the timing belt is being tensioned properly.
If so, remove the wire. In addition, check that the rod
protrusion from the auto-tensioner meets the standard
value, which is also an indication of properly tensioned
timing belt.
Standard value: 3.8 – 4.5 mm
(23)If the wire cannot be removed with a light force, repeat
steps (16) through (21) until the proper belt tensioner
is obtained.
INSPECTION
TIMING BELT
Replace belt if any of the following conditions exist.
(1) Hardening of back rubber.
Back side is glossy without resilience and leaves no indent
when pressed with fingernail.
(2) Cracks on rubber back.
(3) Cracks or peeling of canvas.
(4) Cracks on rib root.
(5) Cracks on belt sides.
