The bearing driver will position the mating
ring (B) to the correct depth with respect to
the mechanical seal (A).
7. Apply a light oil to the drive headplate bearing
bore, bearing inside diameter, and shaft seat.
Install the drive end bearings (14) as far as pos-
sible without force.
8. Attach the puller plate shown on page 13 to the
drive headplate using the tapped holes used to se-
cure the drive cover (see FIGURE 20, page 19).
Tighten the bolts so that the advance of the bear-
ings stay as uniform as possible. Bearings should
be pressed until flush with the drive headplate.
9. Lubricate the gear end bearing fits with a light oil
as described previously. Install gear end bearings
(14) as far as possible without force. Use the plate,
used to install the drive end bearings, to press the
bearings on the shafts as described in Step 8.
Press bearings into the gear headplate until com-
pletely seated in the bearing bore.
Bearings will not be flush with gear
headplate bores when completely
seated.
10. Impellers should now be checked for free axial
movement by hitting the ends of the impeller
shafts with the palm of your hand.
11. Push the impellers against the gear headplate and
recheck the total end clearance between the drive
headplate and the impellers (see FIGURE 21).
A. If total end clearance is insufficient, loosen
impeller case to headplate bolts on either
headplate, and move the headplate away
from the case far enough to insert a paper
shim in the amount equal to the insufficient
clearance. Retighten case bolts and again
check the total end clearance. Refer to
FIGURE 21 for correct clearance.
B. Excessive end clearances normally will
require new impeller assemblies, but in some
