EMA - 64 ENGINE MECHANICAL SYSTEM
CYLINDER BLOCK
1. Remove gasket material.
Using a gasket scraper, remove all the gasketmaterial
from the top surface of the cylinder block.
2. Clean cylinder block
Using a soft brush and solvent, thoroughly clean the
cylinder block.
3. Inspect top surface of cylinder block for flatness.
Using a precision straight edge and feeler gauge,
measure the surface contacting the cylinder head
gasket for war page.
Flatness of cylinder block gasket surface
Standard : Less than 0.05mm(0.0020 in.),Less
than 0.02mm(0.0008in.) / 150 x 150

4. Inspect cylinder bore diameter
Visually check the cylinder for ver tical scratchs.
If deep scratches are present, replace the cylinder
block.
5. Ins
pect cylinder bore diameter
Usi
ng a cylinder bore gauge, measure the cylinder
bor
e diameter at position in the thrust and axial di-
re
ctions.
Standard diameter
92.00 ~ 92.03mm(3.6220 ~ 3.6232in) - 3.3L
96.00 ~ 96.03mm(3.7795 ~ 3.7807in) - 3.8L
