SUPERIOR GRIFFIN COMPRESSORS
CONNECTING RODS Center rod is equal in weight and
strength to the total of the other two WRIST
PINS Wrist pins have oil passages for pressure
lubrication and are bored out to allow weights to
be added for final balancing of the
assembly. CROSSHEADS All crossheads are the same
dimensions regardless of which side they are used
on.
THREE THROW CRANKSHAFT
