Cylinder head proof control
1) Check cylinder head proof using adequate tools and
appropriate gaskets (D), (F), (E) and (G).
2) Introduce hot water at ~ 90° C through (G), at a pressure of
2 ÷ 3 Kg / (cm
2
.)
3) Check there are no leaks through caps.Otherwise substitute
leaking caps applying recommended hydro reacting sealant.
NOTE:
If cylinder head presents leaks through cracks
replace it.
Flatness of support surface of cylinder head
1) Measure cylinder head thickness.
Nominal cylinder head thickness:
150 ± 0,1 mm
2) Using a metallic rule (H) and a thickness calliper (I), measure
flatness of support surface (13) of cylinder head.
If when measuring you notice some lack of flatness proceed
to rectify the support surface noting the following steps:
Data on surface flattening:
• Maximum thickness of chipped material while carrying
out surface flattening :
0.4 mm
• Minimum thickness of cylinder head after work:
149,6 ± 0,1 mm
NOTE:
If in order to achieve surface flattening of the cylinder
head you would need to exceed the specified limits,
substitute cylinder head.
