• The pistons are made of aluminium alloy, which withstands heat and is highly conductive.
• The piston skirt is coated with graphite to reduce friction.
• The offset pistons are used to reduce piston-slapping noise.
• To prevent the piston from being reassembled in the wrong direction, the front mark (←) is on the piston.
• Pistons and connecting rods cannot be disassembled because they are shrinkage fit.
Piston Specification.
• The following piston rings have been adopted: Barrel face ring for top ring, taper under cut ring for second ring, two scuff rings and an expander for oil ring.
• The piston pin is made of chrome steel alloy, which has superior rigidity.
• The connecting rod and the piston pin are shrinkage fit, so that it cannot be disassembled.
