Specifications

rod big end should also face in the same direction. To
insert piston into cylinder, use a ring compressor as
shown in (Fig. 81).
PISTON PIN—INSTALLATION
(1) Secure connecting rod in soft jawed vice.
(2) Lubricate piston pin and piston with clean oil.
(3) Position piston on connecting rod.
CAUTION: Ensure combustion recess in piston
crown and the bearing cap numbers on the con-
necting rod are on the same side.
(4) Install piston pin.
(5) Install clips in piston to retain piston pin.
(6) Remove connecting rod from vice.
PISTON—INSTALLATION
(1) Before installing pistons, and connecting rod
assemblies into the bore, be sure that compression
ring gaps are staggered so that neither is in line with
oil ring rail gap (Fig. 80).
(2) Before installing the ring compressor, make
sure the oil ring expander ends are butted and the
rail gaps located as shown in (Fig. 80).
(3) Immerse the piston head and rings in clean
engine oil, slide the ring compressor, over the piston
and tighten with the special wrench (Fig. 81).
Ensure position of rings does not change dur-
ing this operation .
(4) Face chamber recess side of piston towards
camshaft.
(5) Install connecting rod bolt protectors on rod
bolts.
(6) Rotate crankshaft so that the connecting rod
journal is on the center of the cylinder bore. Insert
rod and piston into cylinder bore and guide rod over
the crankshaft journal.
CAUTION: During piston and rod installation. DO
NOT rotate piston and connecting rod or damage to
the oil jets extending out into the cylinder bore will
occur (Fig. 74).
(7) Tap the piston down in cylinder bore, using a
hammer handle. At the same time, guide connecting
rod into position on connecting rod journal.
(8) Install rod caps. Install nuts on cleaned and
oiled rod bolts and tighten nuts to 29.5 N·m (22 ft.
lb.) plus 60°.
CYLINDER LINER
REMOVAL
(1) Remove cylinder heads (refer to cylinder head
removal in this section).
(2) Remove Oil pan (refer to oil pan removal in
this section).
(3) Remove pistons (refer to piston removal in this
section).
(4) Use tool VM-1001 to remove liners (Fig. 82).
(5) Remove shims from cylinder liner or cylinder
block recess. Keep shims with each cylinder liner.
INSTALLATION
(1) Carefully clean residual sealer from liner and
crankcase, and degrease the crankcase where it
comes into contact with the liners. Referring to (Fig.
83), install the liners in the crankcase as shown (A),
rotating them back and forth by 45° in order to guar-
antee correct positioning.
(2) Measure the liner recess relative to block deck
with a dial indicator mounted on a special tool
VM-1010 A. All the measurements must be taken
on camshaft side . Zero dial gauge on block deck.
(3) Move dial gauge to cylinder liner record read-
ing on dial gauge.
(4) Remove liner and special tool.
