DRIVE LINKAGE AND SHAFTS
One of three types of drive links connects the jaw cylinder clevis to the
jaw pivot assembly shaft. Early vertical machines contained an
unpinned clevis link clamped around the pivot assembly shaft with two
bolts. Later model jaw cylinders with a pneumatic cushion contained a
pin installed through the drive link into the pivot assembly shaft to pre-
vent the drive link from shifting. Recent machines with a hydraulic
cushion have an updated version of the drive link. The newer link has a
wider surface area clamped onto the shaft with four bolts and does not
use a pin.
