Appendix C. Sensor Maintenance
C. Insert a right-angle type of tool, such as an Allen wrench, into bearing.
Cock it slightly to one side and remove both bearings.
D. Install new bearings. Be careful not to introduce dirt particles into
bearings. CLEAN HANDS ONLY! DO NOT ADD LUBRICATION
OF ANY KIND.
E. Reassemble the sensor in reverse order. Be sure to include spacers over
the bearings when replacing the shaft in the bearing mount. After the
magnet assembly has been tightened, a barely perceptible amount of
endplay should be felt when the shaft is moved up and down.
