Bearing housings
Perform these checks when you inspect the bearing housings:
• Check that the bearing housings are very clean, with no burrs.
• Remove all loose and foreign material.
• Check the bearing housing bores against the values in the Ball bearing fits table.
• Repair or replace housings as necessary.
Replace the wear rings
A press fit and three tack welds hold the impeller wear rings (202, 202A, 202B, 203) in place.
1. Remove the impeller wear rings (202, 202A, 202B, 203):
a) Grind out the tack welds.
b) Remove the wear rings from the impellers (101–101M), using suitable pry or puller
tools to force the rings from the fits.
You may also machine the rings in order to remove them.
CAUTION:
Excessive machining can damage ring fits and render parts unusable.
1. Wear ring – 202A (double suction), 202B (double suction for 4x6-10 and 4x6-11
only), 203
2. Impeller – 101 through 101M
3. Wear ring – 202, 202B (first stage)
2. Install new wear rings (202, 202A, 202B, 203):
