IMPORTANT: Corrosion builds up on the
potentiometer sensor plates. Rotate the
potentiometer several revolutions in both
directions by hand. Corroded sensor plates will
result in inaccurate diameter measurements.
7. Remove potentiometer (5). (See CTM for Diameter
Potentiometer Remove and Install).
8. Inspect diameter potentiometer and rotate
potentiometer shaft (6) several revolutions in both
directions by hand.
9. Inspect diameter potentiometer linkage.
