Now move to the blower housing where the shaft comes out
1.
from the bearing. Put the steel debris collar (chrome color
with a rubber seal on one side) onto the shaft with the rubber
gasket side facing the rear of the bearing (away from the
impeller). See Figure #5.
2. Push the steel collar seal up to the bearing and make sure the
groove in the collar goes inside the groove in the bearing.
(Figure #6) This creates the sealed fit to keep debris out of the
bearing.
NOTE:
If the collar is too large for the hole in the bearing plate, a
3.
"new style" bearing plate will need to be ordered that has a
larger diameter hole. Units manufactured before April 2002
will most likely need to be converted to the new bearing
plate (part number LCT600.603 {all but LCT6000} and
LCT630.104A for the LCT6000. This plate is for the blower
housing or impeller side only. The pulley side bearing does
not use the steel debris collar.
4. Completely tighten the two Allen head screws. See figure #6.
NOTE:
Each bearing comes with a steel debris collar but it will be
used only on the bearing on the impeller side. You may dis-
card the other collar if you're replacing the pulley bearing.
