——Check and make sure that the oil injection hole of the
connecting rod large end is not blocked. The outside diameter is
φ1mm.
Installation:
——Need not to divide into groups for the piston weight, piston
pin holes and the accessory piston skirt. Before assembling, check
the piston head mark and make sure that it is in accord with
cylinder No.4.
——Heat the small end of connecting rod to 230°—400℃, and
apply SAE50 engine oil or graphite colloid oil on the outer
circumference of the piston pin hole. Then press the piston pin
into the hole of connecting rod small end and piston pin. One end
of the piston pin may be 0.7mm mostly out of the pin hole or
0.3mm mostly in the seat. And plug the other end of it into the pin
seat.
The piston head means the front arrow. The outer end of
piston pin means the front lug, which should has a same
direction with “F” near the large end of the connecting
rod.(with ‘480’ mark on some blanks and the mark side
forward.)
——After the piston, piston pin, and the connecting rod are put
together, print and sculpture the cylinder numbers with the 3mm
words on the top of piston, the connecting rod and the left side of
rod cap(viewed from the front). Be sure not to be deformed on the
connecting side during printing.
——The dimension of piston ring.

——
When installing the piston ring, the mark side should
be put up and the second compression ring outside cut section
should be put down and remember not to the contrary. Firstly the
oil controlling ring, then the second compression ring, and finally
the first compression ring. As assembling the ring, its maximum
tension should be inferior to the diameter of the cylinder(+1.
65mm), or the ring would be deformed and broken. The two
cotters of the steel band combination oil ring and oil control
spacer ring should be parted with a angle of 120°. And the
cotters of cast iron oil ring and screw spacer ring should be parted
with a interval of 180°. The piston should rotate freely in the ring
groove without blocking.
