Begin by removing the
Piston and connecting rod, followed by using a ring expander tool to get rid of the No. 1 and No. 2 piston rings from the piston. Then, get rid of the upper and lower oil ring side rails together with the ring expander bolt. Check the distance between the piston rings and the inside of the cylinder and be sure to put the No. 2 ring with its manufacturer dot up towards the top of the piston. Arrange the piston rings in the engine as follows: expand oil ring, upper oil ring side rail, lower oil ring side rail, No. 2 intermediate piston ring and No. 1 upper piston ring. For both the side rails, put the free end between the piston and the expander, press it securely and align them in place smoothly and without using a piston expander. Put in the upper side rail first and then place the lower side rail, so that the No. 2 piston ring has its manufacturer's I.D. mark facing up. Afterwards, install the No. 2 piston ring and next the No. 1 piston ring and arrange the end gaps properly, making sure you space the oil ring expander gap at least 45° from the side rail gaps, not just in the center of the piston or moving in the direction of the piston pin.
