7. Position the cylinder (figure 1, item 24) so that it is vertical with the gear end head plate (figure 1, item 9) on
the bottom. Ensure that there is enough clearance under the gear end head plate for the drive shafts
(figure 1, item 4) to be installed properly.
8. Using the chalk match marks made during step 8 of Disassembly, install the impellers (figure 1, item 13) in
the cylinder (figure 1, item 24).
NOTE
The keyed drive shaft must be returned to the same location it was removed from during
Disassembly.
NOTE
Before starting the drive shafts through the gear end head plate's openings, make sure
that the drive shaft ends have no sharp or rough edges that could damage the bearing
seals.
9. Install the drive shafts (figure 1, item 4) in the impellers (figure 1, item 13) and the gear end head plate
(figure 1, item 9), ensuring that the keyed drive shaft is installed in the same location it was removed
from.
10. Apply a thin coat of sealing compound on the outer diameter of the two new bearing seals (figure 1, items 32
and 35).
11. Install the two new bearing seals (figure 1, items 32 and 35) in the drive end head plate (figure 1, item 21) with
the seal lip facing towards the bearings (figure 1, items 31 and 34).
12. Position the drive end head plate (figure 1, item 21) on the cylinder (figure 1, item 24) and verify that the
punch marks made during Disassembly are in the proper location.
13. Install the two dowel pins (figure 1, item 23) in the drive end head plate (figure 1, item 21).
NOTE
The two bolts that secure the drive end feet to the drive end head plate and cylinder are
longer than the other 12 bolts used to secure the drive end head plate to the cylinder.
14. Position the drive end feet (figure 1, item 22) on the drive end head plate (figure 1, item 21) and secure them
to the cylinder (figure 1, item 24) with the 14 bolts (figure 1, item 20).
15. Lubricate the two new bearings (figure 1, items 31 and 34) with a thin coat of lubricating oil.
NOTE
Cylindrical drive bearings should be installed with the inner race large shoulder facing
outboard from the cylinder.
NOTE
Ensure that the drive bearing and the driven bearing are installed in the location they
were removed from. These bearings cannot be used interchangeably. Use the note
made during Disassembly to place these bearings in their proper location and depth.
16. Install the two new bearings (figure 1, items 31 and 34) in the drive end head plate (figure 1, item 21) using a
tube with a flanged end that will contact both bearing faces simultaneously.
