25. HYDRO CONTROL ROD ADJUSTMENT
• If the unit “creeps” in the neutral position, one of
two things may have happened: 1. The hydro
control rod has been bent, causing the unit to
creep or 2. The neutral position adjustment on
the hydro has changed.
25.1. Set the parking brake. The cam in the parking
brake mechanism will lock the pin on the pedal
shaft into neutral.
See Figure 25.1.
25.2. There should now be no tension on the hydro
control rod.If there appears to be tension, look
for a damaged or bent rod.
25.3. Remove the cotter pin securing the ferrule to the
pivot arm on the pedal shaft.
25.4. Remove the ferrule from the hole in the
arm.There should be no tension on the rod
where it connects to the pivot arm.
25.5. If there is, thread the ferrule up or down the
length of the hydro control rod until the post is
centered in the hole that it fits into. At this point,
the transaxle and the linkage should both be
synchronized in neutral.
See Figure 25.5.
25.6. Secure the ferrule to the arm on the pedal shaft
using a new cotter pin.
25.7. Test drive the unit to see if it still creeps. If it does
you will have to adjust the input arm on the
hydro: Confirm that the roller on the return arm
draws fully into the valley in the cam surface on
the front of the input arm.
See Figure 25.7.
