Do not drive the mating ring down to
the mechanical seal, as this can dam-
age the seal.
C. Install mating ring (B) on the drive end short
shaft and the gear end shafts as done in the
previous step, but use spacer (33) (refer to
gear end, FIGURE 18, page 18).
D. Brush the bearing inner race (E) with a light
oil or grease.
E. Using a press and the bearing installation
tool shown on page 14, install the spherical
roller bearing (35) on the drive end drive
shaft. Install the three double row ball bear-
ings on the remaining shaft ends. Bearings
will position the mating ring (B) to the proper
depth with respect to the mechanical seal (A)
when the installation tool is tight against the
headplate.
8. Apply a light oil to the drive headplate bearing
bore, bearing inside diameter, and shaft seat.
Install the spherical roller bearing (35) on the drive
end drive shaft and the double row ball bearing
(14) on the drive end driven shaft. Start the bear-
ing in the bores without force.
9. Attach the puller plate shown on page 11 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 fully seated in the bore.
Bearings will not be flush with gear
headplate bores when completely
seated.
10. 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 fabri-
cated plate, used to install the drive end bearings,
to press the bearings on the shafts as described
