2. Place the piston ring compressor on a wood block, with the chamfered end of the ring compressor facing up.
3. Position (stagger) the piston ring gaps properly on the piston. Make sure the ends of the oil control ring expanders
are not overlapped.
4. Start the top of the piston straight into the ring compressor. Then push the piston down until it contacts the wood
block (Operation I of Fig. 8).
5. Note the position of the matchmark and place the liner, with the flange end down, on the wood block.
6. Place the ring compressor and the piston and connecting rod assembly on the liner so the numbers on the rod and
cap are aligned with the matchmark on the liner (Operation 2 of Fig. 8).
NOTE: The numbers, or number and letter, on the side of the connecting rod and
cap identify the rod with the cap and indicate the particular cylinder in which they are
used. If a new service connecting rod is to be installed, the same identification
numbers, or number and letter, must be stamped in the same location as on the
connecting rod that was replaced.
7. Push the piston and connecting rod assembly down into the liner until the piston is free of the ring compressor.
CAUTION: Do not force the piston into the liner. The peripheral abutment type
expanders apply considerably more force on the oil ring than the standard expander.
Therefore, extra care must be taken during the loading operation to prevent ring
8. Remove the connecting rod cap and the ring compressor. Then push the piston down until the compression rings
pass the cylinder liner ports.
