(5) Lubricate pistons, rings, and cylinder liners
with clean lubricating oil.
(6) Using a standard hand-type ring compressor
to compress rings, insert piston and rod
assembly in liner from bottom of liner.
(7) Assemble new O-ring packings and crevice
seals on cylinder liner as follows:
NOTE
To prevent swelling of O-rings, lubricate
lightly with clean engine lubricating oil,
just prior to installation.
(a) Roll black O-ring with one yellow mark
into position in upper groove. Install the
red silicone O-ring with two blue marks
in lower groove.
(b) Check for twisted O-ring in grooves
using mold mark on rings as guide,
straighten as required.
(c) Install new crevice seal on liner.
(8) Lubricate machined portions of block, on
which packing rings seat, with clean lubricating oil.
CAUTION
Never use white lead for lubricant. White
lead will harden and make cleaning
difficult at next engine teardown.
(9) Lift liner, piston and rod assembly and slide
into cylinder liner bore. Numbers on
connecting rods must be toward outside of
engine. Connecting rods and caps are
numbered
to
correspond
with
their
respective cylinders; numbers on rods and
caps must be matched. Two rods are
assembled on each crank journal.
CAUTION
If liner is difficult to push down, the
packing rings may be twisted or have
slipped. Remove liner to check rings;
use extreme care to avoid twist or cut of
O-rings.
(10) Drive liners to seat with cylinder liner
driver; when liner is near seat, tap gently to
prevent bouncing off seat as liner is driven
in place.
(11) With piston at lowest possible point, check
liner bore for roundness at several points
within range of piston travel. See figure
13-49.
(a) Check with precision dial bore gauge.
(b) Micrometer readings to be taken as
near points C, D, E, F, and G along axis
A-A and B-B.
(c) At point C, approximately 1 inch (25.40
mm) below top of liner, it is permissible
to have up to 0.003 inch (0.08 mm) of
out-of-round.
(d) At other points, each about 2 inches
(50-80 mm) lower than preceding depth,
out-of-round must not exceed 0.002
inch (0.05 mm).
(12) Check liner protrusion at four equidistant
points with a gauge block to determine if
protrusion is uniform and 0.004 to 0.006
inch (0.10 to 0.14 mm) above block.
(13) Lubricate crankshaft side of bearing shells
with a thin coat of clean engine lubricating
oil. Slide upper connecting rod bearing
shells into position between the crankshaft
journals and rods. Be certain bearing shell
locating tang makes firm contact with the
recesses in the rod.
