BEARING REMOVAL
Ball Bearings
A puller, such as the one shown in Figures 23 and 24,
should be used. The puller bar must be square with the end
of the shaft at all times in order to keep even pressure on
the outer circumference of the bearing. The puller screw
should be tightened steadily to enable the bearing to slide
smoothly off the shaft. Do not damage the end of the shaft.
On the SX/MX units, the bearing housings slide off the
bearings and the puller, such as the one shown in Figures
25 and 26, should be used. This type of puller applies force
directly against the bearing itself. The puller bar must be
square with the end of the shaft at all times and the puller
screw should be tightened steadily to enable the bearings to
slide smoothly off the shaft. Do not damage the end of the
shaft.
Roller Bearings
1. Screw the adapter sleeve removal nut (furnished in the
box of fittings which accompanied the pump) onto the
adapter sleeves (item 521). Tightening the nut will
"jack" the sleeves out from under the inner race of the
bearings.
2. Slide the adapter sleeves and bearings off of the shaft
and protect them from contamination. Unscrew the
adapter removal nut and store it for future use.
