OIL t NiET
l The piston skirt is shortened for reduced weight and friction. l A cast iron ring carrier is installed in the piston to reduce piston-ring groove wear. l A cooling channel is incorporated in the body of the piston. The 011 jet squirts oil into this cootrng channel
and the or! absorbs
the heat from around the ring lands, reducing piston ring and cylinder wat! wear
