PRIMARY POWERTRAIN CONTINUED
Transmission Components
0009
The transmission is fastened to the main case at the rear of the machine. Power from the torque divider is sent to
the input shaft by a drive shaft. Power flows from the transmission through the output shaft. The power flows from
the output shaft to the transfer gears.
The transmission has five hydraulically activated clutches. The No. 1 and the No. 2 clutches are the direction
clutches. These clutches are located at the rear of the transmission. The No. 1 clutch is the REVERSE direction
clutch and the No. 2 clutch is the FORWARD direction clutch.
The No. 3, No. 4, and No. 5 clutches are the speed clutches. The No. 3 clutch actuates THIRD speed. The No. 4
clutch actuates SECOND speed. The No. 5 clutch actuates FIRST speed and is the only clutch that turns. Table 2
identifies the callouts of Figure 12.
