34. Rotate the cylinder in the vise so that the bottom end is
facing up.
35. Pre-form the lower packing using the lower packing sizing
tool (included in the repacking kit).
36. Insert the lower packing
assembly partially into the
bottom of the cylinder with
the large beveled edge facing
toward the cylinder (beveled
edge will be facing up when the
cylinder is upright).
37. Push the lower packing
assembly into position using
the lower packing insertion tool
(see Fluid Section Assembly parts list for lower packing
insertion tool P/N).
38. Place the piston insertion tool (included in the repacking
kit) over the top of the piston rod.
39. Insert the piston rod into the bottom of the cylinder, through
the lower packing assembly, through the upper packing
assembly, and out through the upper seal retainer.
40. Tighten the upper seal retainer. Torque to 450–480 in./lbs.
NOTE: When repacking the fluid section, make sure the
raised lip on the bottom of the lower packing
assembly is fully outside the packing around the
piston rod after insertion of the piston rod.
41. Apply blue Loctite to the bottom 3–4 threads on the
cylinder. Turn the jam nut clockwise until it is flush against
the top of the cylinder.
42. Lubricate the first several threads at the top of the cylinder
with anti-seize compound. Remove the cylinder from vise.
43. Thread the cylinder into the pump housing, turning
clockwise. When the connecting pin hole on the piston
rod lines up with the hole in the slider assembly, insert the
connecting pin.
Large Beveled Edge
Install lower packing so
large beveled edge will
be facing up when the
cylinder is upright.

44. Slide the retaining ring down on the slider assembly to
cover the connecting pin.
45. Continue to turn the cylinder clockwise until the jam nut is
flush against the pump housing.
NOTE: If the nipple on the cylinder does not face the back
of the unit, turn the cylinder counterclockwise
until the nipple faces the back of the unit. Do not
turn the cylinder more than one full turn.
46. Once the nipple is positioned, turn the jam nut clockwise
until it contacts the pump housing.
47. Tighten the jam nut with a wrench to tighten it against the
pump housing. Torque to 680–720 in./lbs.
48. Attach the high-pressure hose to the fitting on the back of the
cylinder and tighten with a wrench. Do not kink the hose.
49. Insert the lower support ring and new seal washer into the
bottom of the cylinder.
50. Making sure that the new Viton o-ring and new Teflon
back-up ring are lubricated and in place, reassemble
the inlet valve assembly and thread it into the cylinder.
Use the new parts supplied with the packing kit during
reassembly. Tighten the inlet valve housing until the
o-ring engages, then continue to tighten until snug.
51. Using a wrench, hold the cylinder by the wrench flats and
torque the inlet valve housing to 1020–1080 in./lbs.
52. Thread the siphon tube into the inlet valve housing and
tighten securely. Make sure to wrap the threads on the
siphon tube with Teflon tape before assembly. Replace
the return hose into the clamp on the siphon tube.
53. Place the front cover on the pump housing and secure in
position using the four front cover screws.
54. Turn on the sprayer by following the procedure in the
"Operation" section of this manual and check for leaks.
