Reassembly
Install the turbine bowl and impeller wear ring
1. Place the chamfered face of the bowl or impeller wear ring towards the ring seat and press the ring
into the seat.
2. Use an arbor press or equivalent and make sure the ring is flush with the edge or the wear ring seat.
Install the bowl, suction bell, and lineshaft bearings
Make sure you have an arbor press or equivalent for pressing the bearings.
1. Press the bearing into the retainer.
2. Press the bearing into the suction bell.
The top of the bearing should protrude above the suction hub equal to the depth of the counter bore
in the sand collar.
3. Press the bearings into the intermediate bowl and the top bowl.
4. Place the bowl with the flange downward and press the bearing through the chamfered side of the
bowl hub until the bearing is flush with the hub.
Install the taper collet bowl assembly
WARNING:
Wear protective gloves and use the appropriate eye protection in order to prevent injury when you handle
hot parts.
1. Apply a thin film of turbine oil to all mating and threaded parts.
2. If the pump is equipped with a sand collar, then perform these steps:
a) If the sand collar is not assembled to the shaft, then heat the sand collar until it slips over the shaft
and quickly position it so that the top of the sand collar is even with the locating groove before it
cools.
The sand collar is attached to the shaft with a shrink fit. The shaft is machined with a 0.01 in. (0.25
mm) groove to locate the sand collar. The large diameter of the counterbore of the sand collar
goes toward the suction bell bearing.
b) Slide the end of the pump shaft with the sand collar into the suction bell bearing until the sand
collar rests against the suction bell.
c) Skip the next step and proceed to installing the impellers.
3. If the pump is not equipped with a sand collar, then locate the pump shaft with respect to the suction
bell:
a) Insert the pump shaft into the suction bell bearing until it bottoms out.
b) Pull the shaft out until the distance between the groove on the shaft and the top of the suction
bell hub, and not the top of the bearing, is correct for the particular pump.
Use the X dimension in the Pump shaft dimensions table in the Maintenance chapter.
