DISPLACEMENT PUMP
Reassembly Procedure
1.Stack the backup washer (219*), U±cup seal (205*) lips down, and female gland (220*), alternate the polyethylene and leather v±packings (217*, 218*) lips up, and stack the male gland (213*) one at a time onto the piston valve (224). See Fig 15.
2.Tighten the packing retaining nut (214) onto the piston valve (224) and torque to 3±4 in±lb (0.34 ± 0.35 N.m). See Fig 13.
NOTE: NOTE THE ALIGNMENT of the piston (224) to the nut (214). Maintain this alignment through- out Steps 2, 3 and 4.
