(b) Place the ring compressor on a wood block,
tapered end up, as shown in figure 3-145.
(c) Stagger the piston ring gaps and make sure
the oil control ring expanders are not overlapped (para
(d) Start the top of the piston straight into the
ring compressor; then, push the piston down until it
contacts the wood block (operation 1, fig. 3-145).
(e) Note the position of the matchmark made on
the liner and place the 1 mer on a wood block.
(f) Place the ring compressor and the piston and
rod assembly on the liner, so the number on the rod
and cap are alined with the matchmark on the liner
(operation 2, fig. 3-145).
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 particu-

are clean so the liner flange will seat properly.
e. Installation.
(1) Fit Liner in Bore.
(a) Slide the liner into the block until the flange
on the liner rests on the bottom of the counterbore in
the block.
CAUTlON
Do not drop or slam the cylinder liner flange
against the counterbore in the block.
(b) Tap the liner lightly with a soft hammer to
make sure the liner seats in the bottom of the counter-
bore.
(c) Clamp the cylinder liner in place as shown in
figure 3-144. Refer to table 1-1 and measure the dis-
tance from the top of the liner flange to top of the
block with a dial indicator.
(d) Matchmark the liner and block with a chalk
or white paint so the liner may be reinstalled in the
same position and in the same bore. Place the match-
mark on the outer edge of the engine serial number
side.
(e) Remove hold-down clamp (fig. 3-144) and
cylinder liner from the block.
(2) Install Piston, Connecting Rod and Liner.
(a) With the piston assembled to the connecting
rod and the piston rings in place (para 3-34) apply a
