Right-Hand front road wheel.
Remove the air lter housing/assembly, PAS reservoir
(do not disconnect) and auxiliary belt.
Remove alternator and starter motor. Detach the coolant expansion tank
(do not disconnect), and position to one side.
Remove the coolant pump pulley and upper timing belt cover.
Turn the crankshaft until the timing marks on the VCT Units are in the
11-o-clock position (crankshaft is just before TDC No.1 cylinder).
NOTE: The crankshaft must only be turned in the direction of normal
rotation.

4.1.1 VS3032/21 Crankshaft TDC Location Pin
Remove the blanking plug in the engine block, in order to insert the
VS3032/21 Crankshaft Location Pin.
Carefully and slowly, turn the crankshaft clockwise to rest fully on the
VS3032/21 Location Pin. (Fig.2).
Fig.2
4.1.2 VS4832 Flywheel Locking Tool
Ensure the crankshaft is fully resting on the VS3032/21 Location Pin
and ‘lock’ the ywheel by installing VS4832 Flywheel Locking Tool at the
starter motor position. (Fig.3).
The camshaft timing marks should be at 12-o-clock position. The marks
are located on front of the sprocket teeth – “I” on the Left-Hand sprocket
and “•” on the Right-Hand sprocket.
Remove the crankshaft pulley and discard its centre bolt. Remove the
lower belt cover.
Support the engine and remove the front engine mounting bracket after
marking its installed position.

4.1.3 VS4931 VCT Setting Plate
Fit VS4931 VCT Setting Plate onto the VCT Units. The word “TOP”
should be visible on top of the Setting Plate. The “Scribe Mark I “ should
be on the Left-Hand arm of the Setting Plate, with the “Zero (Dot) Mark 0”
on the Right-Hand arm of the Plate, matching the timing marks on the

4.1.4 VS4640/T7 Tensioner Locking Pin
Apply pressure to the timing belt to activate the tensioner pulley and
allow the insertion of Locking Pin VS4640/T7. (Fig. 5).
Remove the old timing belt and discard.
4.2 Installing new belt
Check that the VCT Setting Plate, Crankshaft Location Pin and Flywheel
Locking Tool are correctly tted.
Install the new timing belt in a clockwise direction, starting at the VCT
Units/camshaft sprocket, then the crankshaft gear. Ensure the belt is taut
between sprockets.
4.2.1 Once the belt is fully tted, remove the VS4640/T7 Tensioner
Locking Pin to release tension on to the belt.
4.2.2 Measure the depth of the bore in the crankshaft to determine the
correct new crankshaft pulley centre bolt to use.
If bore depth is 42mm. – use M12 x 29mm bolt
If bore depth is 52mm. – use M12 x 44.5mm bolt.
Install the lower belt cover.

4.2.3 Install the crankshaft pulley, counter-hold pulley with a suitable
Holding Tool whilst tightening the centre bolt, in two stages, 45Nm. + 90
degrees. (Fig.6).

4.2.4 Remove the VCT Setting Plate, Crankshaft Location Pin and
Flywheel Locking Tool.
4.2.5 Turn the crankshaft carefully, by hand, 2 turns in the direction of
normal rotation and return to the position where the marks on the VCT
Units are at 11- o‘clock.
4.2.6 Insert VS3032/21 Crankshaft Location Pin and carefully turn the
crankshaft to rest fully on the Location Pin.
4.2.7 Fit VS4931 VCT Setting Plate on to the VCT Units and check that
the timing marks on the VCT Units and camshaft sprockets align and
are near to the outer edges of the Setting Plate upper arms. (Fig.7).
If the timing marks do not align, repeat the belt installation and tensioning
procedures.

4.3 Timing Adjustment - Setting the VCT Units
(Cylinder head/Camshaft replacement applications)
When carrying out work on cylinder head / camshaft replacement or
valve timing adjustment it will be necessary to re-set the VCT /
camshafts.
When removing the VCT Units, counter-hold the camshafts, with a
spanner, at the hexagons provided on the camshafts. Remove the centre
blanking plugs of the VCT Units, and unscrew and remove the centre
retaining bolts.
Fig.8
4.3.1 VS4933 Camshaft Setting Plate
When installing the VCT Units, the crankshaft is positioned at TDC No.1
cylinder and VS4933 Camshaft Setting Plate is inserted into the slots
located at the rear of the camshafts to position the camshafts in their
‘timed’ position. (Fig.8).
4.3.2 The VCT Units are placed onto the camshafts and the new centre
retaining bolts are inserted and screwed to nger-tight only.
4.3.3 The timing mark of each of the VCT Units should be positioned at
the 12-o-clock position.
VS4931 Setting Plate is inserted onto the VCT Units and the centre bolts
tightened to 25Nm.
4.3.4 Remove VS4931 and VS4933 Setting Plates.
4.3.5 Counter-hold the camshafts, with a spanner, at the hexagons
provided on the camshafts and carry out the nal tightening procedure –
tightening the VCT centre retaining bolts 75 degrees.
WARNING: DO NOT use VS4931 and VS4933 Setting Plates to
counter-hold camshafts/VCT Units during nal tightening procedure
of the VCT Units retaining bolts.
4.3.6 Insert VS4931 Setting Plate to check that the timing position is
correct and that the timing marks on the sprockets align with the marks
on the VCT Units near to the outer edges of VS4931 Setting Plate upper
arms.
