1. Lubricate O--rings, pressure seals, back--up gaskets
and wear plate grooves with a thin coat of petroleum jel-
ly. Lubricate all other internal parts freely with clean hy-
draulic oil.
2. Install new seals into front flange (Fig. 46.3):
A. Press shaft seal into front flange until it reaches
the bottom of the bore.
B. Install flange washer into front flange and then
install retaining ring into the groove of the front
flange.
C. Install new dust seal into front flange.
3. Place front flange, seal side down, on a flat surface.
4. Install the pressure seals, flat side outward, into the
grooves in the wear plates. Follow by carefully placing
the backup gaskets, flat side outward, between the
pressure seals and the grooves in the wear plate.
5. Apply alight coating ofpetroleum jellyto the exposed
side of the front flange.
6. Lubricate the drive shaft with clean hydraulic oil. In-
sert the drive end of the drive shaft through the wear
plate withthe pressureseal side downand theopen side
of the pressure seal pointing to the inlet side of the mo-
