(3)  Function of Components

[A] Servomechanism

The servomechanism is mainly comprised of the servo piston and proportional valve.

Signals from the HST pedal flow to the ECU and transmit from the ECU to the proportional valve.

The servo piston is controlled by oil from the proportional valve.

Refer  to  Workshop  Manual  of  "TRACTOR  MECHANISM"  (Code  No.  9Y021-18200)  for  the  operation  of  the

servomechanism, that is, the operation of servo piston.



Valves

Check and high pressure relief. As for the mechanism and function of valve, charge relief valve and case relief

valve, Refer to Workshop Manual of "TRACTOR MECHANISM" (Code No. 9Y021-18200).
