Replacement of Oil Chamber O-ring Seal

Should the O-ring seal for the oil chamber bulkhead (Figure 6.10, Bearing

STEPS
1. Remove the retaining ring using a retaining ring pliers.
2. Using a pliers or other gripping tool, pull on the bolt in the center of the
bulkhead to remove the bulkhead and O-ring.
3. Lubricate the new O-ring with grease.
4. Place the O-ring in the groove in the bulkhead.
5. Insert the bulkhead into the bearing frame with the bolt outward.
6. Reinstall the retaining ring.
7. Install the liquid end and remount the pump (Section 6.2.2, Steps 1-4).
Use two 5/16-18NC bolts and a flat plate (not provided) to
bridge across the end of the bearing frame to pull out the seal
holder.
Drill two holes, 3/8-inch (9.5 mm) diameter, through the flat
plate, spacing the holes 3.25 inch (82 mm) apart.
Insert two 5/16-18NC bolts through the plate and turn them
into the seal holder's two coupling nuts provided. (Select bolt
length as needed to engage coupling nuts). Tighten the two
bolts uniformly to pull the seal holder out straight.
