 PISTON/CYLINDER INSTALLATION                                       Top Ring (1st Ring)
 First install the expander in the second ring
 groove.
 Then install the top and second rings in
 their respective ring grooves.
 The piston rings should be pressed into the
 grooves with even force.
 After installation, check and make sure that                          Second Ring
 each ring is flush with the piston at several
 points around the ring.                             Expander
 A ring that will not compress means that the
 ring groove has carbon deposits in it and
 should be cleaned.
