2.5 Position the 86/87 with the gland tight against the seal chamber
face. Turn the gland so that the barrier taps are positioned so that
the associated piping will clear the bearing frame. Tighten the
gland nuts evenly in a diagonal sequence. Do not over tighten
the gland nuts, as this can warp seal parts and cause leakage.
2.6 Assemble the pump. Avoid
pipe strain. Align coupling
properly.
2.7 With the impeller, shaft,
coupling, and bearings in their
final operating positions, tighten
the 86/87 set screws.
See Figure 5.
2.8 Rotate the setting device 180°.
Loosen the hex head bolts
holding the bronze setting
devices and rotate 180° to
clear the drive collar. Retighten
the hex head bolts to store the
setting devices on the gland.
See Figure 6.
2.9 Turn the shaft by hand to
ensure unobstructed operation.
