Removal

All vehicles

1. Remove the engine front Cover. For additional information, refer to Engine Front Cover

Vehicles without supercharger





1. Remove the variable camshaft timing oil control solenoid.





2. Remove variable camshaft timing oil control unit housing.
Remove variable camshaft timing oil control unit housing retaining bolts.






3. Remove and discard the variable camshaft timing oil control unit housing O-ring seals.

All vehicles

NOTE: Vehicles without supercharger shown, vehicles with supercharger similar.

1. Temporarily install the crankshaft pulley and retaining bolt, hand-tight only.
2. Raise the vehicle on the ramp.





3. Remove the crankshaft position sensor.
Remove the bolt which secures the crankshaft position sensor to the flywheel housing.
Remove the sensor and allow it to hang free under the engine.
Remove the access grommet (for torque converter bolts) from the housing.





4. CAUTION: Do not rotate the crankshaft counterclockwise. The timing chains may bind causing engine damage.
Position the crankshaft so the timing slot on the drive plate is visible through the CKP sensor location.





5. Install the crankshaft setting tool 303-531.
Position the crankshaft so the special tool fully engages into the timing slot on the drive plate.

6. Lower the vehicle on the ramp.





7. CAUTION: Under no circumstances should the crankshaft setting peg 303-531 be used in the following operation to lock the crankshaft.
Using the special tools, remove the crankshaft pulley retaining bolt.





8. Using the special tools remove the crankshaft pulley.





9. Install the camshaft locking tool 303 - 530 to the right-hand camshafts, aligning the camshafts as necessary.





10. Loosen the exhaust camshaft sprocket retaining bolt.

Vehicles without supercharger





1. Loosen the variable camshaft timing oil control unit retaining bolt.

Vehicles with supercharger





1. Loosen the intake camshaft retaining bolt.

All vehicles

NOTE: Vehicles without supercharger shown, vehicles with supercharger similar.





1. Remove the primary chain tensioner retaining bolts.





2. Remove the tensioner assembly.
Remove the tensioner.
Remove the tensioner back-plate.





3. Remove the chain tensioner blade.
Remove the pivot bolt which secures the tensioner blade.
Remove the tensioner blade.





4. Remove the right-hand primary chain.





5. Note the orientation of the sprockets relative to each other (half a tooth out of line).

Installation

All vehicles

NOTE: Vehicles without supercharger shown, vehicles with supercharger similar.





1. Install the chain tensioning tool 303-532 to the exhaust camshaft sprocket.
Reposition the sprockets for the most advantageous position for use of the tool.
Remove the tool.





2. Install the right-hand primary timing chain.
Install the primary chain to position over the crankshaft sprocket and the variable camshaft timing oil control unit (or intake camshaft sprocket - vehicles fitted with supercharger). There must be no slack on the drive side of the primary chain and the sprockets must not be rotated on the camshafts (or the tensioning tool may not fit).





3. Fit the primary chain tensioner blade.
Position the tensioner blade to the cylinder block.
Fit the retaining / pivot bolt and tighten it to 12-16 Nm.





4. Push the tensioner piston into the body to provide clearance for fitting.
Install a thin rigid wire through the hole in the end of the tensioner piston to displace the ball from the non-return valve seat.
With the wire in position, press the piston fully into the tensioner body.
Remove the wire.





5. Install the primary chain tensioner back plate.
Install the primary chain tensioner retaining bolts.
Install the primary chain tensioner back plate.





6. Install the primary chain tensioner.
Tighten to 12 Nm.





7. Install primary chain tensioner wedge 303-533 (or two if required) between the primary chain tensioner and tensioner blade, to take up the slack in the chain.





8. Tighten the exhaust camshaft sprocket retaining bolt.
Fit the chain tensioner tool 303-532 to the sprocket holes.
Apply force to the tool in an anti-clockwise direction to tension the chain on its drive side.
Whilst applying the opposing force to the sprocket and chain, tighten the sprocket retaining bolt to 115-125 Nm.

Vehicles without supercharger





1. Rotate the variable camshaft timing oil control unit fully counter-clockwise to the fully retarded position.
Install the variable camshaft timing oil control unit setting tool 303-654.
Rotate the variable camshaft timing oil control unit fully anti-clockwise to the fully retarded position.





2. Tighten the variable camshaft timing oil control unit retaining bolt.
Whilst still applying the opposing force to the sprocket and chain (using 303 - 532), check that the wedges are still in place, carry out the variable camshaft timing oil control unit retaining bolt tightening sequence.
Tighten to 40 Nm + 90°.
Remove the chain tensioning tool and the wedge(s).

Vehicles with supercharger





1. Tighten the intake camshaft retaining bolt.
Whilst still applying the opposing force to the sprocket and chain (using 303 - 532), check that the wedges are still in place, carry out the intake camshaft retaining bolt tightening sequence.
Tighten to 40 Nm + 90°.
Remove the chain tensioning tool and the wedge(s).

All vehicles

NOTE: Vehicles without supercharger shown, vehicles with supercharger similar.





1. Remove the camshaft locking tool 303-530.
2. Raise the vehicle on the ramp.





3. Remove the crankshaft setting tool 303-531.





4. Install the crankshaft position sensor.
Install the sensor to the flywheel housing and fit the securing bolt. Tighten to 8-12 Nm.
Install the access grommet to the housing.

5. Lower the ramp.

Vehicles without supercharger





1. Fit new seals to the variable camshaft timing oil control unit housing.





2. WARNING: Check that the ring dowels are engaged squarely. Fully locate the assembly as much as possible by hand pressure. Failure to follow this procedure may result in damage to the vehicle.

NOTE: Lubricate the seals and the bush.
Install the variable camshaft timing oil control unit housing to the cylinder block.
Install the variable camshaft timing oil control unit housing.
Install the two retaining bolts and one nut. Tighten to 19-23 Nm.





3. Install the variable camshaft timing oil control solenoid.
Tighten to 10 Nm.

All vehicles

1. Refit the engine front Cover. For additional information, refer to Engine Front Cover
