1. Assemble traction pedal using
guides noting the following items:
A. Apply grease to both the OD and ID of the spring retainer (item 23 in
Figure 280) before installation. Take care to not get grease on threads
of spring shaft (19) or jam nut (9).
B. If traction pivot shaft (27) was removed, apply grease to the shaft areas
that will be inside the bearings after assembly.
C. When installing roll pins (11, 17, 21 and 28),make sure to support shaft to
prevent component damage. Use a press to install roll pins. Also, take
care to not distort roll pins during assembly.
D. Make sure that roll pin (17) is fully inside the butterfly groove of the hub
(30). The roll pin should not contact the hub throughout the operating
range.
E. To install the traction pedal position sensor (29), align the slot on the end
of the traction pivot shaft with the slot in the position sensor. Hold position
sensor in position while installing standoff spacers (16), capture plate
(32) and cap screws (33).
F. Leave the jam nut (9) loose so that the position sensor can be calibrated.
2. After traction pedal assembly, make sure that there is no binding in pedal
movement and also that pedal returns to the centered position when
released. Correct any sticking or binding before machine operation.
3. Plug machine wire harness connector into traction pedal position sensor (29).
4. After assembly of the traction pedal, calibrate the traction pedal position
sensor using the InfoCenter display (see
Calibration (page 6–21)).
5. Make sure that jam nut (9) is tightened after position sensor adjustment.
