TRACTION DRIVE MAINTENANCE
LINKAGE MAINTENANCE (FIG. 43)
It is very important that the foot pedal operate freely
and return positively to the NEUTRAL or
CENTERED position. Periodic maintenance of the
traction pedal requires applying grease to the
grease fittings on the linkage control arms as
shown in Fig. 43.

(FIG. 43)
If the traction pedal fails to operate smoothly and
freely, or fails to return to the NEUTRAL position,
the following steps should be checked and
corrections made if required:
1. Check that the traction pedal pivot tube is free
on the pivot pin.
2. Check that the control linkage front and rear
ball joints move freely.
3. Check that no cables, wiring harnesses, etc.
are restricting or interfering with the linkage travel.
4. Check that the linkage centering arms are
pivoting freely.
5. Check that both centering springs are in their
proper position.
6. Check that the control plate is rotating freely.
7. Check that speed control clutch plate is
operating freely.
