11 Ensure that the feet (2) of the Tool No. EN 48313 are
facing the front of the engine.
CAUTION
DO NOT tighten the Tool No. EN 48313 at
this stage.
12 Partially expand the legs (1) on the Tool No. EN 48313 by turning the T-shaped handle clockwise.
CAUTION
Ensure the feet (2) of the Tool No. EN 48313
are correctly engaged into one of the link
pockets to prevent the chain from slipping
during tightening.

14 Hand tighten the Tool No. EN 48313. DO NOT allow the body of the Tool No. EN 48313 to rotate when tightening
the T-handle.
15 Use an open-end spanner on the hex cast into both the right intake and exhaust camshafts and rotate the
camshafts towards each other in order to creat e slack in the chain between the actuators.
16 The Tool No. EN 48313 is now correctly inst alled to hold the timing chain in position.
NOTE
Ensure the camshaft timing chain and the
camshaft position actuators are marked for
correct reassembly.
17 Mark the timing chain and the respective location on both camshaft position actuators.
18 Remove the bolt (1) attaching the right-hand exhaust camshaft sprocket (2) and remove the sprocket.
