4.5.3 Screw in a new pulley securing bolt to finger-tight only.
4.5.4 Fit VS4921 Holding Tool to the crankshaft pulley and use it to
counter-hold whilst tightening the securing bolt to the specified
torque for the engine variant being worked on (fig.20).
4.5.5
If the pulley utilises a split locking ring
– fit a new o-ring seal
to the pulley and apply petroleum jelly to the bore and O-ring.
4.5.6 Fit the pulley on to the crankshaft and fit the split locking ring
inside the bore of the pulley (fig.21).
4.5.7 Screw in a new pulley securing bolt to finger-tight only (fig.22).
4.5.8 Fit VS4921 Holding Tool to the crankshaft pulley and use it to
counter-hold whilst tightening the securing bolt to the specified
torque for the engine variant being worked on (fig.22a).

Adjusting valve timing
The following procedure covers valve timing adjustment and
also applies to setting up the valve timing when installing
camshafts, gears after cylinder head overhaul etc.
4.6.1 Check that the crankshaft is in its ‘timed’ position and that the
appropriate Flywheel Locking Pin has been inserted, as
described in “Checking valve timing”
4.6.2 Remove the water pump pulley.
4.6.3 Remove the front timing chain cover.
4.6.4 Remove the VVT solenoid housing from the inlet camshafts (if
fitted).

4.4.5 Remove the Guide Pin and replace it with the second securing
bolt, passing it through Pulley Remover and the Holding Tool
and into the threaded hole of the pulley (fig.17).
4.4.6 Tighten both bolts,
firmly
, to secure the Pulley Remover and
Holding Tool assembly to the crankshaft pulley.
4.4.7 Prevent the crankshaft pulley from rotating by counter-holding
with the VS4921 Tool. Screw in the Force Screw of the VS4922
Remover to extract the pulley off the crankshaft (fig.18).
4.4.8 Remove the Thrust Plate (fig.19), the crankshaft pulley and the
split ring (if fitted) (fig.19a).
4.5
Installing crankshaft pulley
IMPORTANT:
The thread in the end of the crankshaft must
be cleaned out before installing a new pulley securing bolt. All
mating surfaces should be cleaned.
All except very early pulleys utilise a split locking ring.
4.5.1
If the pulley is a type without a locking ring
- apply Loctite
648 to the bore of the crankshaft pulley.
DO NOT
apply to the
faces or to the crankshaft.
WARNING: The pulley must be fitted and the securing bolt
fully tightened, within 7 minutes of the Loctite being
applied.
4.5.2 Fit the pulley to the crankshaft and wipe off any excess
Loctite.
