7.4 Turbine Bowl-Impeller Wear Ring Removal
1.
Set up impeller in a lathe and machine wear ring off, use extreme care not to machine or damage
ring seat or impeller hub. Impeller wear ring may also be removed by following steps in
Bowl-Wear Rings Removal on page 27
.
7.5 Bowl, Suction Bell, and Discharge Bowl Bearing Removal
1.
Utilizing an arbor press and a piece of pipe or sleeve with outside diameter slightly smaller than
bowl and retainer bearing housing, press the bearing off.
2.
Remove suction bell bearing by setting suction bell on a lathe and machine bearing off. Suction
bell bearing and discharge bowl bearing may also be removed by using bearing pullers and pulling
bearing out.
7.6 Inspection and Replacement
1.
Clean all pump parts thoroughly with a suitable cleaner.
2.
Check bearing seats for deformation and wear.
3.
Check shafts for straightness and excessive wear on bearing surfaces. Check deflection of shafts,
average total runout shall not exceed 0.005 TlR for every 10 feet.
4.
Visually check impellers and bowls for cracks and pitting. Check all bowl bearings for excessive
wear and corrosion.
5.
Replace all badly worn or damaged parts with new parts.
7.7 Turbine Bowl and Impeller Wear Ring Installation
1.
Place chamfered face of bowl or impeller wear ring towards the ring seat and press into seat. Use
an arbor press or equal. Make sure ring is flush with edge of wear ring seat.
7.8 Bowl, Suction Bell, and Discharge Bowl Bearing Installation
1.
Press bearing into suction bell using an arbor press or equal. See
4.1 General Description on page
2.
Press bearings into intermediate bowl and top bowl. Place the bowl with the flange downward and
press bearing through chamfered side of bowl hub until bearing is flush with hub. Use an arbor
press or equal.
7.9 Turbine Bowl With Taper Collet-Reassembly
1.
For ease in reassembly of bowl assembly apply a thin film of turbine oil to all mating and threaded
parts.
2.
If a pumpshaft (660) is replaced, the sand collar is to be attached last to the shaft by a shrink fit.
The shaft is machined with an 0.01 inch groove to locate sand collar, place large diameter of coun-
terbore on sand collar towards discharge bowl bearing. Heat sand collar until it can slip on shaft.
3.
To complete reassembly, reassemble in reverse order of
