19. Check the cylinder cover assembly

a. Place the cylinder cover in fixing device of the cylinder
cover.

b. Clean the combustion surfaces on the cylinder body and
the cylinder cover.

c. Use a ruler and feeler gauge to check the flatness of the
combustion surface of the cylinder cover.
Maximum from the front to the back: 0.305mm
Maximum from left to right: 0.076mm

If it exceeds the technical specifications, it is necessary to
determine whether the cylinder cover surface can be
repaired and the cylinder cover must be replaced:
• Measure and record the valve depth.
• Measure and record the injector protrusion.
0.50mm can be machined separately from the combustion
surface of the cylinder cover, the upper surface of the
cylinder body, or the cylinder body or cylinder cover surface
in total at most. This engine provides oversized cylinder
cover gasket for maintenance. If the valve depth and injector
protrusion can be maintained within the technical
specifications, the cylinder cover surface can be reworked.
If the technical specifications cannot be maintained, the
cylinder cover must be replaced.

d. Measure the injector protrusion and the valve depth.
• Install injector and compact clamp.
