Do not drive the mating ring down to the mechanical seal, as this can damage the seal.
C. Install mating ring (B) on the drive end short shaft and the gear end shaft as done in the previous step, but use
spacer (33) (refer to gear end Figure 7-1, page 29).
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 24, install the spherical roller bearing (35) on the
drive end drive shaft. Install the three double row ball bearings 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.

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 and the double row ball bearing (14) on the drive end driven shaft. Start the bearing
in the bores without force.
9
Attach the puller plate shown on page 11 to the drive headplate using the tapped holes used to secure the drive
cover (see Figure 7-2, page 21). Tighten the bolts so that the advance of the bearings stay as uniform as possible.
Bearings should be pressed until fully seated in the bore.
NOTICE
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 fabricated plate, used to install the drive end bearings, to press the bearings on the
shafts as described in Step 9. Press bearings into the gear headplate unit completely seated in the bearing bore.
