ABSTRACT:
Apparatus for installing a set of dissimilar piston rings (12,14,20,38) which must be arranged in proper predetermined order and orientation in an internal combustion engine piston. The apparatus includes a ring supporting element 48 for retaining the set of piston rings in the order in which they will be installed, order sensing means (115,136,138) for producing an electrical disabling signal if a corresponding ring is not in a predetermined sequential order and a plurality of orientation sensing means (140,142) for producing an electrical disabling signal if a corresponding piston ring is not in its proper orientation. Expanding means (60) responsive to a control means (174) operates to expand the set of rings to allow coaxial insertion of a piston and subsequently to relax the rings into corresponding grooves of the piston as long as a disabling signal has not been generated by the corresponding sensing means (115,136,138,140,142). Each sensing means has an electro-optic device including an optic fiber cable (86,88,90,96) extending between a corresponding piston ring and sensor means circuit (122,124,126,128,130,132,134).
