Bearing Removal and Replacement.
First, remove the 2 Phillips head screws that secure the dust cap to the wheel center. You may need to tap the dust cap with the screwdriver handle to break it loose.
Next, using the 1/8" hex wrench, loosen the upper collar set screw and remove the upper collar. You may need to wet the collar and shaft with vegetable oil the collar does not easily remove. After several applications of vegetable oil, use pliers to rotate the collar. Upward pressure with rotation should remove the collar.
The bearings are a flanged, press fit ball bearing. To remove the bearings, insert a screwdriver into and through the hole in the bearing. Gently tilt the screwdriver to the side. This will lift the flange of the bearing. Next, insert the edge of the screwdriver under the flange and twist the screwdriver slightly so the bearing begins to elevate. Repeat this in several positions around the bearing so the bearing moves up evenly. If this is done gently, no damage to the wheel will occur. If high, uneven force is used, you may bend the bearing seat. This can be repaired but gradual removal of the bearing should avoid damage. Continue elevating until the bearing comes free of the bearing hole. Take a new bearing and press it in with your thumb.
Refer to the pictures below for the various steps.
