REMOVAL SERVICE POINTS

TIMING CHAIN TENSIONER REMOVAL

1. Insert a flatblade screwdriver into the release hole of the timing chain tensioner to release the latch.

2. Push the tensioner lever by hand and push in the plunger of the timing chain tensioner until it hits the bottom. Then, insert a hard wire (piano wire or the like) of φ1.5 or hexagonal bar wrench (1.5 mm [0.06 inch] ) into the fixing hole of the plunger.

3. Remove the timing chain tensioner.

INSTALLATION SERVICE POINTS

INTAKE V.V.T. SPROCKET BOLT INSTALLATION

1. Assemble the intake V.V.T. sprocket assembly in the following procedure.

2. Install the V.V.T. sprocket.

3. Make sure that the V.V.T. sprocket is securely inserted into the bottom and that the V.V.T. sprocket does not rotate with the hexagonal portion of the camshaft secured with a wrench.

4. Hold the hexagonal portion of the camshaft with a wrench and tighten the intake V.V.T. sprocket bolt to the specified tightening torque.

Tightening torque: 59 +- 5 N*m (44 +- 3 ft-lb)

TIMING CHAIN INSTALLATION

1. Align the timing mark of the V.V.T. sprocket.

2. Align the crankshaft sprocket keys with illustrated positions.

4. Align the link plate (blue) with the timing mark of the intake V.V.T. sprocket to loop the timing chain.

Rotate the intake V.V.T. sprocket by one or two teeth to align with the timing mark.

5. Align the timing mark of the crankshaft sprocket with the link plate (blue) to loop the timing chain. Because the timing chain slacks, hold it to prevent the timing mark from coming off the link plate.

6. Make sure that the timing mark of each sprocket is aligned with the link plate of the timing chain at all of three locations.

7. Install the timing chain guide and tensioner lever.

TIMING CHAIN TENSIONER INSTALLATION

1. Install the timing chain tensioner on the cylinder block and tighten it to the specified torque.

Tightening torque: 10 +- 2 N*m (89 +- 17 in-lb)

2. Remove the hard wire (piano wire or the like) of φ1.5 or hexagonal bar wrench (1.5 mm [0.05 inch] ) from the timing chain tensioner. This enables the plunger of the timing chain tensioner to push the tensioner lever to keep the timing chain tight.

INSPECTION

INTAKE V.V.T. SPROCKET

CAUTION

Never overhaul the V.V.T. sprocket.

1. Seal with a tape all the intake camshaft ports for the advanced angle and the retarded angle.

2. Make a hole on the port for the advanced angle.

Mitsubishi Outlander. Engine Overhaul

CAUTION

Fix the camshaft on a vise not to damage it.

3. Fixing the hexagonal area of the intake camshaft on a vise, install the intake V.V.T. sprocket.

CAUTION

When applying air pressure, keep in mind that oil could splash.

4. By applying air pressure slowly to the holed port for the advanced angle, remove the stopper pin.

5. Turn the intake V.V.T. sprocket housing in the right and left directions. Check it smoothly moves in the range of A (approximately 20º)

NOTE: The stopper pin is locked in the most retarded angle position.

6..After the check, remove the intake V.V.T. sprocket from the intake camshaft

7. Completely remove the tape sealing the intake camshaft ports for the advanced angle and for the retarded angle.

5. Turn the exhaust V.V.T. sprocket housing in the right and left directions. Check it smoothly moves in the range of A (approximately 10º)

NOTE: The stopper pin is locked in the most advanced angle position.

6. After the check, remove the exhaust V.V.T. sprocket from the exhaust camshaft

7. Completely remove the tape sealing the exhaust camshaft ports for the advanced angle and for the retarded angle.

VALVE CLEARANCE ADJUSTMENT

Measure valve clearance in the following procedure.

CAUTION

Always rotate the crankshaft clockwise.

1. Rotate the crankshaft clockwise to align the timing mark of the V.V.T. sprocket with the top surface of the cylinder head as illustrated. (Set the Number 1 piston at top dead center on the compression stroke.)

Mitsubishi Outlander. Engine Overhaul

2. Valve clearance can be measured at the illustrated location in this condition.

Mitsubishi Outlander. Engine Overhaul

3. Use a free gauge to measure clearance between the camshaft and valve tappet.

Standard value (when engine is cold):
Intake side: 0.20 +- 0.03 mm (0.008 +- 0.001inch)
Exhaust side: 0.30 +- 0.03 mm (0.012 +- 0.001 inch)

4. If measured values are out of the standard value, record measured values.

Mitsubishi Outlander. Engine Overhaul

5. Rotate the crankshaft by one turn clockwise to set the Number 4 piston at top dead center on the compression stroke.

NOTE: The timing mark of the V.V.T. exhaust sprocket must be at the illustrated position.

6. Valve clearance can be measured at the illustrated location in this condition.

7. If measured values are out of the standard value, record measured values.

8. If the measured value is out of the standard value, replace the valve tappet.

NOTE: There are 47 kinds of valve tappets at intervals of 0.015 mm (0.0006 inch) in the range between 3.000 mm (0.1181 inch) and 3.690 mm (0.145 inch).

9. Select a valve tappet in the following procedure.

  1. Measure thickness of a removed valve tappet.
  2. Calculate thickness of a valve tappet so that valve clearance meets the standard value.

A: Thickness of valve tappet to be selected
B: Thickness of removed valve tappet
C: Measured valve clearance

Formula
Intake side: A = B + (C − 0.20 mm [0.08 inch] )
Exhaust side: A = B + (C − 0.30 mm [0.012 inch] )

Refer to "Removal and installation of camshaft" for removal, installation and inspection procedure of valve tappets.
