bearing after cleaning, DO NOT allow
it to spin. The bearing could come
apart and cause serious injury. Always
wear safety glasses.
D. Spindle housing for damage or wear.
E. Pulley assembly, if the shaft shows
signs of wear inspect the pulley for
excessive wear in the splines. If
excessive wear is found, replace the
pulley. Excessive wear of the splines
will show up as sharp edges on the
splines.
Note: New bearings are only available in
matched sets. The matched set is
necessary because the bearing end-
play is not adjustable. The small "C"
shaped spacer is machined to specifi-
cally match the bearings in the set.
The advantage of a matched set is the
ability to torque the assembly to a
specified value and have a pre-set
endplay. Alternatively, most tapered
bearing applications use either a crush
washer or a castle nut with key as a
means to set endplay.

it also contacts the snap ring. Now press
