Seal Drive Installation
Step 1 Lubricate the exposed surfaces of the sleeve gasket and sleeve gasket
ends, rotating face gasket ends, and seal drive split joint gaskets with the
enclosed lube. Confirm that the set screws are backed out of the seal drive
bore so the set screws do not interfer with seal drive fit around the shaft.
Step 2 Loosely assemble the seal drive halves around the shaft and slide
the seal drive toward the box until the setting devices contact the box face.
Step 3a With the seal drive still loose, align the rotating face joints at their OD and
at the face so there is no step at the joints.

b Finish tightening the seal drive cap
screws to 4.5 N-m (40 in-lbs). Recheck
the rotating face joints for flatness.
A small mismatch can be corrected by
pushing on the high side of the joint or
gently prying on the low side.
c The rotating face joints must be flat and
smooth. Any mismatch will result in
leakage. If a mismatch exists, loosen
the seal drive cap screws 1-2 turns and
repeat steps a and b.
d Clean rotating face with alcohol.
