Piston - Refitting

Connect piston to connecting rod after lubricating piston pin and
introducing it by exerting pressure with your thumb.
Position the two piston pin circlips and check that they are well
inside their seats.
Using a ring compressor introduce the piston into the cylinder
with combustion chamber facing the injection pump side.

Piston position and clearance

To obtain a clearance of 0.67÷0.90 mm measure protrusion A of
all pistons from the cylinder plane and consider the A value of
the most protruding piston.
Perform this measurement along the engine axis.

Cylinder head gasket

Warning
• Remove the head gasket from its protective wrapping only when
ready for fitting.
At B the gasket shows small semi-circular notches indicating
thickness.
Choose the proper head gasket considering that for each value
of A (maximum projection of the piston from the cylinder surface)
there is a matching gasket among the three available (with no
notch, one notch or two notches) to achieve a clearance volume
between 0.66 and 0.90 mm.
In the LDW 1503 / 1603 engines the head gasket is made of fibre,
while in the LDW 2004 / 2204-T / 2204 / 2204-T engines the head
gasket is metal.

from the cylinder head plane; you can
thus determine the gasket thickness
before taking down the head.
