2. Install the outboard bearings (112A) on the shaft (122).
The regreasable bearing has a single shield. Make sure that the bearing is installed with the shield away
from the impeller.
The duplex bearings are mounted back-to-back. Make sure that the orientation of the bearings are
correct.
a) Inspect the shaft (122) to ensure that it is clean, dimensionally correct, and is free of nicks and
burrs.
b) Lightly coat the bearing seating with a thin film of oil.
c) Remove the bearings (112) from their packaging.
d) Wipe the preservative from the bearing (112) bore and outer diameter.
e) Use an induction heater with a demagnetizing cycle to heat both bearings (112) to an inner ring
temperature of 230 °F (110 °C).
f) Place both bearings (112) on the shaft (122) with the large outer races together (back-to-back).
g) Position the bearings (112) on the shaft (122) against the shoulder and snug the locknut (136)
against the bearings until they are cool.
The locknut prevents the bearings from moving away from the shaft shoulder as they cool. Rotate
the outer bearing rings relative to each other as they are placed on the shaft to assure good
alignment.
h) Remove the bearing locknut (136) after the bearings (112) are cool.
