Connecting Rod: Description and Operation
PISTON & CONNECTING RODDESCRIPTION
NOTE: No over sized pistons are available.
The pistons are of a free floating design and made of optimized aluminum alloy with a graphite coated bearing surface. The crown of the piston has been designed to accommodate higher injection pressures. Oil jets in the engine block lubricate and cool the piston and pin assembly. The connecting rods have a pressed in place wrist pin bushing featuring specially adjusted lubrication grooves which are lubricated by the oil jets (Fig. 36). The steel connecting rods feature a small end of trapezoidal shape and a cracked large end.
