PRECAUTIONS:

1.1.   Wear of the cylinder liner and protection ring inner diameters depends on the quality of the fuel oil used, control of lubricating oil, and cooling water temperature. Progress of wear causes problems such as blow-by and increase in the consumption of lubricating oil, and therefore when the parts reach or come close to the use limit, be minded to replace them in an earlier stage.

1.2.   In case of the corrosion or cavitation is found, the following possible reasons can be considered:

        1) Cooling water rust preventive agent is not effectively working.

        2) Cooling water pressure is low.

        3) Cooling water is mixed with air.

        Conduct appropriate cooling water control in strict conformance with the Control Standard.

1.3.   Pale gray-brownish deposit is a film of the rust preventive agent that has been used. Therefore, do not remove it.

1.4.  1) Do not apply silicone rubber to the O-ring.

        2) After silicone rubber is applied, assemble the cylinder liner at a little earlier timing heffner it dries.

DESCRIPTION:

It follows NOx technical files and has the NOx ID on its body.

CERTIFICATION:

Certified with BV certificate

PRECAUTIONS:

1.1.   Since the items mentioned in this section will be the parts to which NOx Technical Code shall be applied, when replacing any of these parts, be sure to use the parts provided with the identification marks.

1.2.   The exhaust manifold mounting bolt is made of stainless steel. Be careful not to mix with other general bolts.

1.3.   When suspending the cylinder head, be sure to use the specified suspending implement, and be minded to strictly observe the use standard of the wire rope.

1.4.   Since the items mentioned in this section will be the parts to which NOx Technical Code shall be applied, when replacing any of these parts, be sure to use the parts provided with the identification marks.

1.5.   Do not use a gas burner to remove carbon. It may cause hardening of the O-ring due to high temperature and deterioration of the materials due to local heating.

1.6.   Do not apply any anti-seizure agent or lubricant oil to the cylinder head gasket surface.

1.7.   Be careful not to mistakenly attach the cylinder head tightening nut with the upper and lower surface upside-down.
