20. Bolt outboard bearing housing in place. Be sure that both
housings are seated in lower half casing.
21. Bolt inboard bearing housing in place. If seal is a John
Crane Type 8, set seal to dimensional shown in Fig. 27
and tighten set screws.
22. Clean the gasket surfaces of the casing. Apply Scotch
3M-77 spray adhesive or equivalent to the lower half
of the casing.
23. Within one minute of spraying, set the gaskets (351D &
351S) in place on the lower half casing, align the holes in
the gaskets with the holes in the casing and press the
gaskets firmly against the lower half casing face in the
area coated by the adhesive.
24. Lower upper half casing (100) into place (See
Fig. 28) and locate using the taper dowels (469G) and
install casing main joint bolts (426 & 426A). The casing
joint bolts should be tightened to the following torques:
300 ft-lb minimum for .75"-10 Ferry Cap Countr-bor
screws (Grade 8), 400 ft-lb minimum for 1.0"-8 Ferry
Cap Countr-bor screws (Grade 8). Bolt torquing pattern
is shown in Fig. 39. The number of casing bolts varies
with the size of the pump (See Fig. 23). Before tightening
bolts, be sure taper dowels are seated properly in reamed
holes.
NOTE: Torquing bolts to proper values in proper
sequence is essential in obtaining proper gasket
compression so no leakage can occur at main joint.

CAUTION
Double check rotation of pump before installing the
upper casing (Refer to Fig. 15).

casing. Seal water lines should be piped to the tapped
holes nearest bearings (See Fig. 23).
28. Check coupling alignment and redowel if necessary.
