Introduction - PISTONS AND CONNECTING RODS

1.9 JTD 8V

CONNECTING RODS

The connecting rods are made from hardended 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 light aluminium-silicon alloy pistons with autothermic inserts are graded in three sizes.

The "OMEGA" combustion chamber is located in the piston crown to improve combustion.

Two copper alloy bushes assist the matching with the gudgeon pin.
