•
Risk of physical injury from hot bearings. Wear insulated gloves when using a bearing
heater.
6.4.2 Tools required
In order to disassemble the pump, you need these tools:
•
Bearing puller
•
Cleaning agents and solvents
•
Dial indicators
•
Feeler gauges
•
Induction heater
•
Lifting sling
•
Micrometer
•
Rubber mallet
•
Screwdriver
•
Spanner wrench
•
Torque wrench with sockets
•
Wrenches
•
Lifting eyebolt (dependent on pump / motor size)
6.4.3 Drain the pump
CAUTION:
•
Risk of physical injury. Allow all system and pump components to cool before handling.
•
If the pumped fluid is non-conductive, drain and flush the pump with a conductive fluid un-
der conditions that will not allow for a spark to be released to the atmosphere.
6.4.4 Prepare for disassembly
WARNING:
Dropping, rolling or tipping units, or applying other shock loads, can cause property damage
and/or personal injury. Ensure that the unit is properly supported and secure during lifting and
handling.
Before you begin, refer to the appropriate sectional drawing for either the radial suction or end suction
configuration.
1.
If you plan to disassemble the entire pump for maintenance work, place the pump in a vertical posi-
tion with the suction nozzle facing up.
A workbench with a hole that is approximately 0.50 in. (1.27 cm) larger than the shaft is helpful in
such cases.
2.
For pump sizes 1.5 x 2.5-7 and 2.5 x 4-8, place the pump on the coupling guard adapter (234A).
3.
For pump sizes 4 x 5-10 and 5 x 6-11, stand the pump vertically with an additional support. You
must also have a hoist or a second person for disassembly.
6.4.5 Disassemble the discharge end ball bearing for the radial suction
configuration
1.
Remove the coupling halves.
