5. Slide deflector and end cap against sleeve nut.
6. Lift oil ring over oil ring collar to clear housing.
7. Slide bearing housing off bearings.
8. Remove in sequence the following parts:
Oil ring (17)
0 Bearing lock nut (2 1-4)
0 Bearing lock washer (31)
0 Oil ring collar (82-2)
Ball bearing (81-1)
Oil ring (17)
Oil ring collar (82-2)

Note: Both inboard and outboard bearing housing and components are
identical, with the exception of

a. Inner oil ring collar at outboard bearing is machined to special
width for each pump to obtain correct setting of shaft in relation
to stuffing box face.
b. The outboard bearing housing utilizes a bearing spacer (25) to
allow the thrust bearing to position the rotating element.

9. Slide end cap (13-1) and deflector from shaft. After inspection has
been carried out to verify component integrity, reassembly can be
made as follows:
a. Slide deflectors (29) on shaft against sleeve lock nut.
b. Slide end cap (13-1) over shaft against deflectors.
c. Install in sequence these parts:

Oil ring collars (82-2) (special at thrust bearing)
Oil ring (17)
Oil ring collar (82-2)
Bearing lock washer (31)
Bearing lock nut (214)
Oil ring (17)

d. Place 1/16 in. thick gasket (154) over inboard end cap and push
inboard bearing housing over bearing (watch oil rings); insert
dowels and bolt into place.
e. Bring inboard end cap forward and tighten cap screws.
f. Without placing end cap gaskets, slide outboard housing over
bearing, bring end cap forward and tighten cap screws between
end cap and housing finger tight.
