Figure C–20. Removing the Upper Drive Bearing
Replacement
1. Use a small-tip Phillips screwdriver to guide a self-tapping screw through the screw holes in
the right upper frame. Applying pressure, turn the screw into the holes in the drive bearing.
NOTE: Be sure the flat edge of the bearing is against the frame. Continue until the
screw is 1/2 to 3/4 of the way in. Install the second screw in the same
manner until it is tight. Now tighten the first screw.
2. Before installing the upper drive shaft, apply a single drop of “3-IN-ONE” oil to the inside of
the shaft bearing.
3. Reverse the steps in Figure C–12 to install the shaft, motor and motor cover.
