3232829 - 1028H pistons and connecting rods

CONNECTING RODS

The connecting rods are of hardened and tempered steel, with copper bush (1) in which the gudgeon pin (2) fits.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

They are made from cast iron and are the type which are supported at the bottom with the coolant fluids coming into direct contact from the outside for a more even dissipation of the heat (when wet).When refitting the engine, check that the projection of the cylinder liners/bores in relation to the cylinder block/crankcase is within the recommended values.
