Reassembly (See Fig. 2)
1. Lubricate the packing nut and all packings and
seals with silicone-free lubricant, such as no. 2
lithium-base grease, before reassembling.
2. If it was necessary to disassemble the displace-
ment rod assembly, reassemble the upper and
lower caps (38d, 38f) and the plunger rod (38e) to
the displacement rod (38c). Screw the plunger rod
through the lower cap until it protrudes the re-
quired distance as was recorded in step 12 of
Disassembly.
3. Install the male gland, v-packings, and female
gland in the outlet housing (6), as shown for your
pump model (see Fig. 3). Install the v-packings
one at a time, with the lips facing down.
4. Install the gasket (7*) in the outlet housing (6).
Loosely install the packing nut/wet-cup (2). Insert
the displacement rod assembly in the bottom of
the outlet housing and push it up until the threads
of the upper cap (38d) are roughly level with the
top of the packing nut/wet-cup. (This makes it
easier to connect the coupling nut when the dis-
placement pump is reinstalled on the motor.)
