Troubleshooting
JCF-Z Rotor Identification
1
On the first few uses of a new JCF-Z rotor, or in an older JCF-Z rotor with newly replaced bearings, run
the rotor from 0 to 5000 rpm and back to 0 rpm three times.
• This procedure will distribute lubricant around the bearings in the rotating seal assembly,
reducing drag.
2
In older JCF-Z rotors with bearings that have not been replaced recently, follow the same procedure
as for a new JCF-Z rotor (perform three runs from 0 to 5000 rpm and back to 0 rpm) to ensure
that the bearings are properly lubricated.
• If misidentification recurs after the third run, when the bearings are lubricated, this
indicates that the bearings are worn and need to be replaced.
a. Replace the bearings following the instructions in the JCF-Z manual (JCFZ-IM).
NOTE
If the JCF-Z rotor is misidentified, the run speed will be limited to the maximum speed for the
identified rotor. (The maximum speed for the JCF-Z rotor is 20 000 rpm.)
