REMOVAL SERVICE POINTS

<<A>> CAMSHAFT SPROCKET REMOVAL

1. Use the following special tools to hold the

camshaft sprocket.

•

Front hub and flange yoke holder (MB990767)

•

Pin (MD998719)

2. Loosen the camshaft sprocket mounting bolt and

remove the camshaft sprocket.

<<B>> EXHAUST ROCKER ARM AND SHAFT
ASSEMBLY/INLET ROCKER ARM AND SHAFT
ASSEMBLY REMOVAL

CAUTION

Never disassemble the exhaust rocker arm and
shaft assembly, and inlet rocker arm and shaft
assembly.

<<C>> VALVE SPRING RETAINER LOCKS
REMOVAL

CAUTION

When removing valve spring retainer locks, leave
the piston of each cylinder in the TDC (Top Dead
Centre) position. The valve may fall into the
cylinder if the piston is not properly in the TDC
position.

Use special tool valve spring compressor
(MD998772) to compress the valve spring and then
remove the valve spring retainer lock.

INSTALLATION SERVICE POINTS

>>A<< VALVE STEM SEALS INSTALLATION
1. Apply a small amount of engine oil to the valve

stem seals.

CAUTION

•

Do not re-use the valve stem seal.

•

Special tool valve stem seal installer
(MD998774) must be used to install the valve
stem seal. Improper installation could result
in oil leaking past the valve guide.

2. Use the special tool to fill a new valve stem seal in

the valve guide using the valve stem area as a
guide.

>>B<< EXHAUST VALVE SPRINGS/INLET VALVE
SPRINGS INSTALLATION

Install the valve springs with its identification colour
painted end facing the locker arm.

>>I<< CAMSHAFT POSITION SENSOR SUPPORT
INSTALLATION
1. Remove sealant from the camshaft position

sensor support and cylinder head surfaces.

2. Apply the sealant to the camshaft position sensor

support flange in a continuous bead as shown in
the illustration.

Specified sealant: MITSUBISHI GENUINE
PART MD970389 or equivalent

NOTE: Install the camshaft position sensor
support within 15 minutes after applying the
sealant.

3. Install the camshaft position sensor support to the

cylinder head.

CAUTION

Wait at least one hour. Never start the engine or
let engine oil or coolant touch the adhesion
surface during that time.

>>J<< O-RING/OIL CONTROL VALVE
INSTALLATION

CAUTION

•

Never re-use the O-ring.

•

Before installing O-ring, wind the tape with the

soft adhesion (sealing tape) around the oil
passages cut-out area of engine oil control
valve to prevent the damage. If the O-ring is
damaged, it can be the cause of oil leak.

1. Apply a small amount of engine oil to the O-ring

and then install it to the oil control valve.

2. Assemble the oil control valve to the cylinder

head.

3. Tighten the oil control valve mounting bolt to the

specified torque.
