ASSEMBLY (continued)
17. Place the swing bolts (40) in the proper positions and secure the two casing halves (7 and 38) together with the nuts (6)
and bolts (5).
18. Place the packing rings (25) over the pump shaft (13) and slide them, one at a time, into the stuffing box. Alternate the
position of the ring splices 120 apart. Position the lantern rings (26) so that the seal water passage is in line with the ring
splice.
19. When packing is complete, place the split glands (41), gland clips (4), and split gland nuts (3) on the swing bolts (40).
Draw the split gland nuts down tight to seat the bottom rings of the packing, then loosen the split gland nuts to finger
tight for starting.
20. Turn the pump by hand and ensure that it turns without binding. The packing will provide resistance to turning, but
should not bind the pump.
21. If the pump was removed from the boat for repair, install it following the procedure in the Installation procedure in this
work package.
22. Align the pump (WP 0145 00).
23. Install the pump drive shaft (WP 0146 00) and pump piping (WP 0144 00).
24. Remove the lockouts and tagouts, set the fire monitor to discharge overboard, and operate the pump.
! CAUTION
Do not overtighten the packing. Overtightening can cause burning of the packing and
scoring of the pump shaft.
25. Tighten the split gland nuts (3) only enough to slow the flow of water past the packing. The desired flow rate is 3 to 4
drops per minute. Overtightening of the packing can burn the packing and score the pump shaft.
26. After checking the operation and adjusting the packing, secure the pump.
