DESCRIPTION
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 pis-
ton 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. 37). The steel connecting rods fea-
ture a small end of trapezoidal shape and a cracked
large end.
