Remove/Install
Angular Contact Bearing
1. Remove the rotor from the test cell.
2. Inspect the thermowell for damage or wear. Replace it if necessary.
3.
Try to fit the new bearing onto the thermowell. If the bearing is too tight,
use sand paper or emery cloth to sand down the shaft until the bearing
goes on and off smoothly.
4. Remove the magnet and magnet holder from the rotor.
5.
Using a flathead screwdriver and hammer, tap the pivot bearing until it
falls out.
6.
With the bearing installer, firmly push the new bearing all the way into the
rotor.
The rotor and bearings are designed with a very tight tolerance so that
the outer surface of the bearings can grip the walls of the rotor while still
being inserted and removed easily. It is common for the bearing to slip
while inside the rotor. This will not affect data quality, but it could make
cell assembly and disassembly more difficult if the bearing slips out of the
rotor. To prevent this, you can either replace the bearing or sand down
the outer edge to create a rough surface. Then use alcohol to remove any
metal shavings.
7. Reassemble the rotor.
