PISTON RING - REMOVAL
(1) ID mark on face of top and second piston rings
must point toward piston crown.
(2) Using a suitable ring expander, remove top and
second piston rings (Fig. 52).
(3) Remove upper oil ring side rail, lower oil ring
side rail and then the oil expander from piston.
(4) Carefully clean carbon from piston crowns,
skirts and ring grooves ensuring the 4 oil holes in
the oil control ring groove are clear.
INSPECTION
PISTONS
(1) Piston Diameter: Size: 91.912-91.928mm
(3.6185-3.6192 in.) Maximum wear limit .05mm
(.0019 in.).
(2) Check piston pin bores in piston for roundness.
Make 3 checks at 120É intervals. Maximum out of
roundness .05mm (.0019in.).
(3) The piston diameter should be measured
approximately 15 mm (.590 in.) up from the base.
(4) Skirt wear should not exceed 0.1 mm (.00039
in.).
(5) The clearance between the cylinder liner and
piston should not exceed 0.065-0.083 mm
(.0025-.0032 in.).
(6) Make sure the weight of the pistons does not
differ by more than 5 g.
CONNECTING RODS
(1) Assemble bearing shells and bearing caps to
their respective connecting rods ensuring that the
serrations on the cap and reference marks are
aligned.
(2) Tighten connecting cap bolts to 29 N´m (21 ft.
lbs.) plus 60É.
(3) Without loosening connecting rod bolts, tighten
all bolts to 88N´m.(4) Check and record internal diameter of crank
end of connecting rod.
NOTE: When changing connecting rods, all four
must have the same weight and be stamped with
the same number. Replacement connecting rods
will only be supplied in sets of four.
Connecting rods are supplied in sets of four since
they all must be of the same weight category. Max
allowable weight difference is 5 gr.
NOTE: On one side of the big end of the con-rod
there is a two-digit number which refers to the
weight category. On the other side of the big end
there is a four digit number on both the rod and the
cap. These numbers must both face the injection
pump side of the block (Fig. 53). Lightly heat the
piston in oven. Insert piston pin in position and
secure it with provided snap rings.
The Four digit numbers marked on con rod
big end and rod cap must be on the same side
as the injection pump (Fig. 53).After having
coated threads with Molyguard, tighten con rod bolts
to 29 N´m (21 ft. lbs.) plus 60É.
PISTON PINS
(1) Measure the diameter of piston pin in the cen-
ter and both ends.
(2) Piston pin diameter is 29.992 to 29.996mm
(1.1807 to 1.1809 in.).
