assembly, determined by the numbers stamped on
the crown of individual pistons. Engine cylinders are
numbered starting from gear train end of the engine.
Face arrow on top of piston toward front of
engine. Therefore, the numbers stamped on connect-
ing rod big end should face toward the injection
pump side of engine. To insert piston into cylinder
use a ring compressor (VM.1065) as shown in (Fig.
57).
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. 56).
(2) Before installing the ring compressor, make
sure the oil ring expander ends are butted together.
(3) Immerse the piston head and rings in clean
engine oil, slide the ring compressor, over the piston
and tighten (Fig. 57).Ensure position of rings
does not change during this operation.
NOTE: Be sure arrow on top of piston faces
towards front of engine.
NOTE: Be careful not to nick crankshaft journals.
(4) 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.(5) Tap the piston down in cylinder bore, using a
hammer handle. At the same time, guide connecting
rod into position on connecting rod journal.
(6) Install connecting rod caps (Fig. 58). Install rod
bolts and tighten to 30N´m (22 ft.lb.) plus 60É. Then
torque to 88N´m (65 ft.lb).
(7) Install cylinder head (Refer to 9 - ENGINE/
CYLINDER HEAD - INSTALLATION).
(8) Install balance shaft assembly (Refer to 9 -
ENGINE/VALVE TIMING/BALANCE SHAFT -
