1) 2 sizes of piston are available as standard size spare part so as to ensure proper piston-to cylinder clearance. When installing a standard size piston,
make sure to match piston with cylinder as follows.
a) Each piston (8) has stamped number (9) on its piston head. It represents outer diameter of piston.
b) There are also stamped numbers (10) or painted color (10) on cylinder block as shown in figure.
c) Stamped number on piston and painted color (stamped number) on cylinder block must correspond. That is, install number "2" stamped piston
to cylinder which is identified with blue painted (or "2" stamped) and a number "1" piston to cylinder with red painted (or "1" stamped).
