Unless otherwise specified, re-attachment is carried out by
reversing the order of detachment operations. In particular,
comply with the following instructions:
Verify the conditions listed below, which refer to the tools
used for valve timing:
- tool 99360614 (6, SENZA CODICE) must be inserted

into the overhead;

- tool 99360615 (11, SENZA CODICE) must be inserted

into the base unit.

Verify that the junction planes of the cylinder head and the
base unit are clean.
Do not soil the cylinder head gasket.
Place the cylinder head gasket with the “TOP” writing facing
the head itself.

Fit the cylinder head, insert the screws and tighten up in three
subsequent steps, by following the sequence and indications
shown in the next figure.

The gasket must strictly be kept sealed in its own
package and be unwrapped soon before being
fitted.

Angle lock is carried out by means of tool
99395216.

Place chain (1) on gear (5) and on gear (2).
Fit the gear in such a way that when it is inserted onto the
dowel bolt of the intake valve distributing shaft, slots A will
be positioned as shown in the figure.

Place chain (1) on gear (2), then fit the latter onto the exhaust
valve distributing shaft.
Screw down fastening screw (4) with washer (3) without
tightening up.

Check the conditions of moving pads (1 and 3): if they are
worn, they shall be replaced together with the other
camshaft drive components.
Position moving shoes (1 and 3), then secure them to the
base unit with pin (2) by tightening the latter to the specified
torque

Screw down hydraulic chain stretcher (2), then tighten it to
the specified torque.
Insert, through the opening on the overhead, a suitable
screwdriver, then press on moving shoe (4) fin (3) until chain
stretcher (2) piston (1) is pushed to its end of stroke.
Release moving shoe (4), and make sure that piston (1)
causes, by escaping from its seat, chain (5) to be subjected
to tension.

Screw down fastening screw (4) with washer (3) without
tightening up.

The chain (1) branch included between the two
gears must be subjected to tension.
