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 with
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.
