Elevation Potentiometer Harness Assembly Replacement - GE T2100 Service Manual

Elevation Potentiometer Harness Assembly Replacement

1. Lower T2100 Treadmill to 0% grade.
2. Turn the ON/OFF switch to the OFF position, disconnect the power cord from
the wall outlet, and remove the shroud.
3. Remove old potentiometer harness assembly. See
Sub-Assemblies" on page
CAUTION:
DO NOT apply any pulling force to the potentiometer shaft. If this does occur, the
entire potentiometer harness will require replacement.
The potentiometer is susceptible to damage resulting from an axial pulling force
on the shaft (see figure).
Potentiometer Installation Procedure
1. Remove the nut and washer from the potentiometer.
2. Attach the mounting plate to the potentiometer and secure with the washer
and nut provided.
3. Attach the plastic coupling tube to the potentiometer to approximately 1/3rd
of the coupling tube length, such that there is sufficient length remaining to
attach to the elevation shaft. Do not press the tubing on any farther than it
needs to. We want to avoid pulling the tubing off the shaft if it is pressed on too
far (see caution statement).
4. While looking at the shaft end of the potentiometer, rotate the shaft CCW until it
stops. Then rotate the shaft 1–2 turns CW.
5. Attach the harness assembly to the unit by guiding the potentiometer (with
tube attached) through the clearance hole in the chassis tower. Make sure
the harness assembly is oriented such that the mounting plate holes are in
general alignment with the threaded stand-offs. This must be done in order to
maintain the 1–2 turns established in Step 4. Also be sure that the cables are
toward the rear of the T2100 Treadmill. Attach the tube far enough on to the
2021403-120F
