3308459 - 1028H pistons and connecting rods (Automatic transmission)
CONNECTING RODS
The connecting rods are made from hardened
and tempered steel, with a copper bush (1) fitted for matching the
gudgeon pin (2).The floating gudgeon pins are secured by
two circlips (3) seated in specific grooves in the piston skirts.
PISTONS
The aluminium-silicon alloy pistons with
autothermic inserts (1) are graded into three sizes; to ensure correct
assembly, an arrow is stamped on the crown to show the direction
of rotation of the engine. The piston crown is concave and has four
notches to prevent interference with the valve heads.
CYLINDER LINERS/BORES
They are made from cast iron and are the
type which are supported at the bottom with the coolant fluids coming
into direct contact with the outside to ensure a more even dissipation
of the heat (when wet).When refitting the engine, check that the
cylinder liner/bore projection in relation to the cylinder block/crankcase
is within the recommended values.
