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.
