IMPORTANT: Note position of the open and closed
side of the wear plates before removing. Identify
wear plates (inner and outer, drive gear and idler
gear) with a marker for proper assembly.
IMPORTANT: Mark the relative positions of the gear
teeth so they can be reassembled in the same
(mated) position. Do not touch the gear surfaces as
residue on hands may be corrosive to gear finish.
7. Carefully disassemble the inner wear plate, idler
gear, drive gear and outer wear plate.
8. Remove and discard back−up gaskets and pressure
seals from wear plates.
9. Turn front flange over, with seal side up.
IMPORTANT: Make sure to not damage the front
flange counter bore when removing the seals from
the front flange.
10.Carefully remove dust seal, retaining ring, backup
washer and shaft seal from the front flange (Fig. 63).
Discard removed seals.
Inspection
1. Remove any nicks and burrs from all parts with
emery cloth.
CAUTION
Use goggles or other appropriate eye protection
when using compressed air for drying parts.
2. Clean all parts with solvent. Dry all parts with com-
pressed air.
3. Inspect drive gears and idler gears for the following
(Fig. 64):
A. Gear shafts should be free of rough surfaces and
excessive wear at bushing points and sealing areas.
Scoring, rough surfaces or wear on gear shafts indi-
cates need for replacement.
B. Gear teeth should be free of excessive scoring
and wear. Any broken or nicked gear teeth must be
replaced.
C. Inspect gear face edge for sharpness. Sharp
edges of gears will damage wear plates and should
be replaced.

4. Inspect wear plates for the following:
A. Bearing areas should not have excessive wear or

should be free of wear, roughness or scoring.
C. Thickness of wear plates should be equal.
5. Inspect front flange and rear cover for damage or
