(1) Before installation, check whether the gap between the Bare Engine end and the edge meets the technical requirements. When installing the old ring, install the ring groove according to the original cylinder number and original order. When installing the Isuzu Engine, special tools should be used.

(2) When installing, install the oil ring first, then install the gas ring, and install the chrome-plated barrel ring or chrome-plated rectangular flat ring.

When installing the second and third conical rings, pay attention to facing the side marked with the word "up" toward the cylinder head. If there is a groove on the inner edge of the twisted ring, the groove should face up; if there is a groove on the outer edge, it should be installed downward.

Install the spiral spring lined oil ring in the fourth pass. When installing, first open the spring from the joint, put it into the Bare Engine groove, insert the joint, and then install the cast iron ring.

The chamfered side faces up, and the opening should be opposite the spring joint. In addition, the openings of the Bare Engine should be staggered by 90°~120° from each other, and the opening should not be in the direction of the pin hole, and the openings of each steel sheet of the combined oil ring should also be staggered from each other.

(3) After the Isuzu Engine is installed, the ring should be able to rotate freely in the ring groove and fall onto the supporting surface in the groove by its own weight. Lubricating oil should be added to each moving part.
