17. Position the cylinder (figure 1, item 24) so that it is vertical with the gear end head plate (figure 1, item 9) on
the top. Ensure that there is enough clearance under the drive end head plate (figure 1, item 21) for the drive
shafts (figure 1, item 4).
18. Lubricate the two new bearings (figure 1, item 28) with a thin coat of lubricating oil.
NOTE
gear end head plate shoulders.
19. Using an arbor press, install the bearings (figure 1, item 28) in the gear end head plate (figure 1, item 9).
20. Install the two bearing clamp plates (figure 1, item 27) on the gear end head plate (figure 1, item 9) and
secure them with four new self locking cap screws (figure 1, item 26).
21. Position the cylinder (figure 1, item 24) on a flat surface on its gear end feet (figure 1, item 19) and drive end
feet (figure 1, item 22).
22. Loosen, but do not remove, the two bolts (figure 1, items 17 and 20) that secure the gear end feet (figure 1,
item 19) and the drive end feet (figure 1, item 22).
23. Level the gear end feet (figure 1, item 19) and the drive end feet (figure 1, item 22) and secure the two bolts
(figure 1, items 17 and 20).
24. Wedge the impellers (figure 2, item 1) with blocks of hardwood (figure 2, item 2) to keep them from turning
during assembly.
NOTE
Gears must be returned to their original drive shaft. Use the note made during Disas-
sembly to place the gears on the proper drive shaft.
25. Install the drive gear (figure 1, item 16) and the gear nut (figure 1, item 15) on the drive shaft (figure 1, item 4)
using notes from step 12 of Disassembly as a guide.
26. Torque the drive gear nut (figure 1, item 14) to 60 lb-ft (81.3 Nm).
NOTE
Gears must be returned to their original drive shaft. Use the note made during Disas-
sembly to place the gears on the proper drive shaft.
27. Install the driven gear (figure 1, item 16) on the drive shaft (figure 1, item 4) using notes from step 12 of
Disassembly as a guide.
28. Remove the hardwood (figure 2, item 2) from the impellers (figure 2, item 1).
29. Using a long set of feeler gauges, check the impeller (figure 1, item 13) fronts and backs clearances as
indicted in table 1 and figure 3. The feeler gauge thickness should be a value in between the two values
indicated in table 1.
