3.1.1. Remove the eight socket head capscrews (64) in the discharge port of the manifold
(36) which secure the pick-up tube (1) to the manifold.
3.1.2. Insert the pick-up tube center guide all the way into the pick-up tube (1) and push or
tap lightly until the pick-up tube moves free of the pick-up tube o-ring (49) and
manifold (36).
3.1.3. Remove the four hex nuts (45) which secure the manifold (36) to the endbell (26) lift
and remove the manifold (36) from the endbell (26). Place the manifold on a flat
surface with the manifold ports facing down.
3.1.4. In this position, carefully remove the seal retaining ring (91) from the manifold (36). To
remove the mechanical seal (75) from the manifold, use the seal puller included in the
tool kit, or gently tap the back side of the mechanical seal with a brass rod inserted
through the discharge port of the manifold (36) until the mechanical seal is free to be
removed by hand.
3.1.5. Using an O-Ring pick, remove the mechanical seal o-ring (44) and pick-up tube o-ring
(49) from the manifold (36).
3.1.6. Install a rubber or cloth shield between the pick-up tube (1) and the seal mating ring
(78) in the rotor cover (4), to protect mating ring face.
3.1.7. Using a hand tool (P/N 0661977), remove the seal mating ring (78) from the rotor
cover (4) until the seal mating ring is free to be removed by hand.
NOTE: If only the mechanical seal (75) and seal mating ring (78) replacement
is necessary, no further disassembly is required. See section 4.5 for
reassembly of seal.
See section 3.3 for rotor cover and pick-up tube removal.
3.2. ROTOR ASSEMBLY REMOVAL AND DISASSEMBLY
WARNING: Before lifting the pump into the vertical position first remove the
lifting eye and install the swivel hoist. When tightening the swivel hoist ring, torque
to 100ft-lbs. Once the pump is re-assembled and in the horizontal position remove
the swivel hoist and re-install the lifting eye. Reference APPENDIX 4 Drawing.
Recommended the unit is mounted vertically with the shaft downward and the
rotor facing upward when rotor assembly is removed.
3.2.1. Remove two of the nine endbell socket head capscrews (63) at nine o'clock and three
o'clock. Install the two endbell alignment rods (P/N 060580573). In place of the two
capscrews, remove remainder of socket head capscrews (63). Thread eyebolts (P/N
06055404) into three evenly spaced, tapped jackscrew holes and using a sling, lift
and remove the endbell (26) from the rotor case (117E).
