i. After the cylinder is cleaned, it is necessary to use
the crack detection unit to check again whether there
are cracks, abrasions and discolorations that prevent
further use in the cylinder body.
Pay close attentions to the following areas of
cylinder:

• Main bearing cap and hole
• Camshaft hole
• Cylinder hole

• Tappet hole
• Oil sump installation surface
• Front and rear of cylinder body sealing surface

• Oil cooler chamber

j. Be sure to check whether there are cracks,
abrasions and discolorations in the main bearing
cover and main bearing saddle area. If any crack is
found, the cylinder must be replaced.

k. Check whether there are damaged screw threads in
all bolt holes. Spiral thread inlays can be used to
repair the damaged threads.

l. Check whether the cylinder hole is polished. The
unpolished surface is with an anaglyphic appearance
and the line forms an angle of 25° to 30° with the top
Wear out of the cylinder hole.
