(1) Before installation, check and confirm whether the gap between the end and edge of the Bare Engine 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 Bare Engine, special tools should be used.

(2) When installing, install the oil ring first, then the gas ring. One is a chrome-plated barrel ring or a chrome-plated rectangular flat ring. Second, three conical rings, note that the side with the "up" text mark faces the cylinder head.

If it is a twisted ring with a cut groove on the inner edge, the cut groove should be placed upward; if there is a cut groove on the outer edge, it should be installed downward.

Fourth, install the spiral spring lined oil ring. When installing, first open the spring from the joint, put it into the Bare Engine groove, insert the human joint, and then install the cast iron ring with the chamfered side facing up, and the opening should be opposite the spring joint. In addition, the openings of each MG Roewe Maxus 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 MG Roewe maxus 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 all moving parts.
