FIGURE 7-13 – SEAL INSTALLATION GUIDE
With the hydrodynamic seals, the bearing carrier must be lowered over the shaft first. The
installation
sleeves
must be used
to cover keyways and to provide smooth transitions onto the
diameter
changes.
NOTICE
Seals must stay on the shipping rings until it is time to install them. Otherwise the lips will
deform. It is best to store them so the shipping ring is laying on a flat surface.
Never hang a lip seal through the bore.
14. Slide the protective installation sleeves over each shaft (Figure 7-14). Install the green outside
diameter oil seal (27) on the main rotor shaft and the red outside diameter oil seal (28) on the
gate rotor shaft. The dirt lip and the rotation arrow should be down. Drive the seal flush with the
bottom of the oil channel cast inside of the bearing bore. Remove installation sleeves and store
for later use on the gear end.
15. With micrometer, (FIGURE 7-15, page 46), measure the thickness of shaft shim sets established
in Step 5 thru 8. Be sure shims are clean of dirt and oil for true measurement.
16. Check the end of the bearing spacer for dirt and burrs. Be sure the bearing spacer is solid
against the rotor. Slide shim set over the shaft extension, (FIGURE 7-15 page 46), up against
the end of the bearing spacer.
