Place the bearings on to the black bearing plates inside the
pedistal. Hand tighten the bolts onto the nuts at this point.
Slide the shaft through the back of the impeller bearing and
half way to the pulley bearing. The shaft should fit tight.
Clean the shaft and remove any burrs if necessary. Also
lightly polishing it with a fine emery may ease installation.
Before going through the pulley bearing, place both concen-
tric collars (black collars) onto the shaft (figure #1). Make
sure the grooved side is facing the bearing.
Continue sliding the shaft through the pulley bearing until the
shaft protrudes out from the pulley side 5-5/8". (Figure #2)
Now slide the concentric collar toward the respective bearing
making sure the grooved side is toward the bearing.
Turn the concentric collar clockwise until it slips over the
inner ring extension and engages the eccentric. Turn by hand
until the parts are locket together.
Place a punch or drift in the blind hole in the collar and strike
it sharply to lock the collar and ring tightly together (figure
#3)
Tighten the set screws with an Allen wrench until the set
screw stops turning and the Allen wrench starts to spring.
(Figure #4)
Completely tighten all four of the nuts to secure each bearing.
