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.

Step 2

b Finish tightening the seal drive cap

screws to 4.5 N-m (40 in-lbs). Recheck

the rotating face joints for atness.

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 at 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.

Step 1

Step 3
