Service

Reassembly (See Fig. 2)

1.Lubricate the packing nut threads 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 (27, 10) and the plunger rod (23) to the displacement rod (8). 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 (24), 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 (24). Loosely install the packing nut/wet-cup (1). Insert the displacement rod assembly in the bottom of the outlet housing and push it up until the threads of the upper cap (27) are roughly level with the top of the packing nut/wet-cup. (This makes it easier to connect the coupling nut when the displacement pump is reinstalled on the motor.)

1Apply sealant to male threads and torque to 80–90 ft–lb (108–122 N.m).

2Lips of v-packings must face down.

3Lubricate threads and torque to 20–24 ft–lb (27–33 N.m).

4Lubricate.
