DISASSEMBLY INSTRUCTIONS
To disassemble the Roto-Jet pump, refer to
Section 2.3
. The following instructions are
applicable to the pump being removed from its foundation and placed securely into a vertical
position in which the pump shaft is pointed downward and the endbell is facing up.
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 B Drawing.
3.1.
PREPARATION FOR DISASSEMBLY
(1) Disconnect the motor, lockout and tag.
(2) Block off the suction and discharge.
(3) Slack off belt tension; remove belts and pump sheave, or disconnect flex coupling.
(4) Disconnect and remove all piping from the manifold.
(5) Drain oil from the oil sump.
3.2. CAUTIONS
The following precautions are recommended to insure satisfactory pump operation after
assembly.
3.2.1 Replace any o-rings that are exposed during the pump disassembly process as they
lose their seal integrity and may leak.
3.2.2 Be sure all parts are free of dirt, stray metal chips, or any foreign matter and have
been thoroughly cleaned.
3.2.3 All torque values given assume lubrication with anti-seize on threads and underside
of cap screw heads (unless otherwise stated.) Refer to Section 2.3 for torque
values.
3.2.4 All three bearings should be replaced as a set.
3.2.5 To avoid creating an out of balance condition that makes the pump susceptible to
vibration damage, match mark cap screws and rotor cover relative positions for
reassembly into the same positions.
3.2.6 Replacement of the rotor, rotor cover, or driveshaft will require balancing of rotating
assembly and shimming of pump. See
sections 6 and 8
.
