Oil Seal Replacement

Frame Overhaul) is leaking.
Oil leaking from the ports in the bearing frame near the liquid end indicates oil seal #1
(Figure 6.10) is leaking.

WARNING: TO PREVENT OIL LEAKAGE, DO NOT TO DAMAGE THE
SEAL LIP.
The oil seal rubber must be lubricated with grease or oil and the shaft
key way must be covered to protect the oil seal from damage.
A thin metal sleeve placed over the end of the shaft will suffice. Taper
the sleeve on the end so the seal can be easily slipped on the end. As
an alternate, thin plastic tape, applied 1-1/4 wrap at a time, can be
used to cover the key way.
Install the three 5/16-inch bolts and lock washers to secure the
bearing frame cap.
Install the liquid end on the bearing frame (Section 6.2.2,
Steps 1-5).
Mount the pump on the bedplate or other mounting, and position and
tighten the clamp on the discharge support.
Align the coupling (Section 3.5, Motor, Pump & Coupling Alignment).
Lubricate pump bearings (Section 3.12, Lubrication of Pump Bearings).
Remove the flexible coupling guard (Figure 6.10).
Either remove the pump or motor from the bedplate or other mounting,
or swing the motor shaft away from the bearing frame shaft.
Remove the flexible coupling flange and key from the bearing frame
shaft.
