3A.1.2.2.6. SELECTION OF CYLINDER HEAD

GASKET

1. Measure the piston projection in two places at 180°

on the gudgeon pin axis using the tool (1)

287158900643 (Dial guage mount) 1 and take the

average of the two values measured for each

piston.

2. Select the correct size cylinder head gasket,

according to the maximum value of the averages

for the projection for each individual piston. Refer

the table below.

21. Position the pressure pump (1a), complete with

coupling (1b) and a new o-ring, in its housing

and tighten the M7 bolts (1c) to the

recommended torque of 1.4 ~ 1.7 Kg-m.

22. Place the vacuum unit (2a), complete with gasket

(2b), back in its housing and secure it tightening

the M8 bolts (2c) to the recommended torque of

1.8 ~ 2.2 Kg-m .

NOTE

Follow the order shown in the figure for each

tightening sequence. The tightening to

2.0 Kg-m is performed in two stages: a

pretightening to 0.5 Kg-m followed by an

additional tightening of 1.8 -2.2 Kg-m .

23. Remove the support tool complete with camshaft

housing from the vice and separate them.
