valve ring recess that will face down when installed.
Install the valve ring over the bolts and alignment pins
with the seal ring facing the isolation manifold (Fig. 98).
IMPORTANT: Be sure the seal ring is seated cor­
rectly after the valve ring is assembled.
36. Put the hex drive assembly, pin side up, through the
hole in the isolation manifold (Fig. 99). the slot in the hex
drive must be engaged with the SMALL tang of the drive

NOTE: If the hex drive does not readily assemble on the
drive link, the drive link was assembled incorrectly (See
step 22 of this procedure.)
