ENGINE BLOCK
DESCRIPTION
The 2.5L CRD Diesel engine uses a cast iron
engine block with wet cast iron cylinder liners (Fig.
33).
CRANKSHAFT
DESCRIPTION
The crankshaft is a forged steel type design with
five main bearing journals. The crankshaft is located
at the bottom of the engine block and is held in place
with three main bearing supports (Fig. 34).
OPERATION
The crankshaft transfers force generated by com-
bustion within the cylinder bores to the flywheel or
flexplate.

INSPECTION
The cylinder walls should be checked for out-of-
round and taper with a dial bore gauge. The cylinder
bore out-of-round is 0.100 mm (.0039 in.) maximum
and cylinder bore taper is 0.100 mm (.0039 in.) max-
imum. If the cylinder walls are badly scuffed or
scored, new liners should be installed and honed, and
new pistons and rings fitted.
Measure the cylinder bore at three levels in direc-
tions A and B (Fig. 42). Top measurement should be
10 mm (3/8 in.) down and bottom measurement
should be 10 mm (3/8 in.) up from the bottom bore.
INSTALLATION
(1) Carefully clean liner and engine block, and
degrease the engine block where it comes into contact
with the liners. Install the liners in the engine block
as shown, rotating them back and forth by 45É in
order to guarantee correct positioning (Fig. 43).
(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 high pressure pump side of engine block..
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.
(5) Then select the correct shim thickness to give
proper protrusion (0.01 - 0.06 mm).
(6) Fit the shim and the O-rings onto the liner.
(7) Lubricate the lower liner location in the block.
(8) Fit the liners in the crankcase making sure
that the shim is positioned correctly in the seat. Lock
the liners in position using special tool (VM.1076)
and bolts (Fig. 44). Clean the residual LOCTITE on
the upper surface of the block deck.
(9) Recheck the liner protrusion. It should be 0.01
- 0.06 mm.
(10) Reassemble engine.
(11) Install engine in vehicle.

PISTON & CONNECTING ROD
DESCRIPTION
The pistons are of a free floating design. Oil jets in
the engine block lubricate and cool the piston and pin
assembly. The connecting rods have a pressed in
place wrist pin bushing which is lubricated by the oil
jets (Fig. 48).

down with piston to ensure it is square in bore. The
ring gap measurement must be made with the ring
positioning at least 12 mm (0.50 in.) from bottom of
cylinder bore (Fig. 49). Check gap with feeler gauge.
Top compression ring gap .30 to .45mm (.0118 to
.0177 in.). Second compression ring gap .30 to .45mm(.0118 to .0177 in.). Oil control ring gap .25 to .50mm
(.0098 to .0196 in.).
(2) If ring gaps exceed dimension given, new rings
or cylinder liners must be fitted. Keep piston rings in
piston sets.
(3) Check piston ring to groove clearance (Fig. 50).
Top compression ring gap .080 to .130mm (.0031 to
.0051 in.). Second compression ring gap .070 to
.110mm (.0027 to .0043 in.). Oil control ring gap .040
to .080mm (.0015 to .0031 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.).
