INSTALLATION
Tool (2) is fitted in to the solenoid valve aperture of each
camshaft, safely locking the camshaft VVT units in position
while fitting the crankshaft pulley central bolt. Ensure that the
central boss of each tool moves freely in the outer ring of the
tool before fitting them to the engine.
Fit tool (2) in to the inlet camshaft VVT unit, attaching the outer
ring to the timing belt cover using 3 screws tightened to the
specified torque settings. Apply an anti-clockwise force to the
central boss to take up any play in the VVT unit, then tighten
the 6 locking screws to the specified torque settings.
Fit tool (2) into the exhaust camshaft VVT unit, attaching the
outer ring to the timing belt, using 3 screws tightened to the
specified torque settings.
Apply an anti-clockwise force to the central boss to take up any
play in the VVT unit, tighten the 6 locking screws to the
specified torque settings.
Using a new bolt, fit the crankshaft pulley into the crankshaft, finger
tight only at this stage. Take care not to damage the reluctor ring
on the rear of the crankshaft pulley. Ensure that the alignment hole
of the pulley is positioned at approximately at 10'clock relative to
the pulley central bolt. Insert tool (6) through the alignment hole in
the pulley and into the alignment hole on the engine block.
IMPORTANT: The crankshaft pulley central bolt is tightened to a
very high torque. Use a torque multiplier and mounting bracket to
aid installation of crankshaft pulley central bolt and prevent torque
forces being transmitted through the engine and vehicle
components.
Remove the torque multiplier (if used). Refit (6) into the crankshaft
pulley alignment hole to check that the pulley is correctly aligned.
