(2) Installation of piston rings
• Install the rings using a piston ring expander with
their “T” marks turned upwards. But the oil rings
have no markings, so they can be installed with
either side up.
• The gaps of the ring and ring expander of the oil
ring should be set apart 180° from each other.
Note:
As No.1 and No.2 compression rings have dif-
ferent cross sections, take care not to install them
in wrong order.
