They are consolidated into one housing (A). The electronic steering clutch and brake control valve (B) is mounted to the top of the main case. The four-section power train oil pump (D) is driven by a shaft that connects the drive hub (C) to a drive hub on the rear of the hydraulic demand fan pump (not pictured). The drive shaft is covered by a guard when the machine is completely assembled. The transmission charging section and the torque converter charging section of the power train oil pump draw their oil from the main sump through the screened suction manifold (E). The suction screen is accessible for cleaning by removing the cover (F) on the front of the suction manifold. The vent line (G) connects the torque converter housing and the main case to maintain an equal atmospheric pressure inside both components. The four-section, fixed displacement power train oil pump is mounted to the left, front of the main case. This fixed displacement gear pump consists of: The two, 6-micron power train oil filters are located at the rear of the machine. Shown in the illustration above is the torque converter charge filter (A) and the transmission charge filter (B). The ecology drain (C) for the transmission case is also located at the rear of the machine, at the bottom of the transmission case (D). The transmission hydraulic control may be accessed by removing the transmission inspection cover (E), at the top of the transmission case. The 6-micron transmission charge filter "A" (F) is located at the upper left, rear of the main case. Service points located on this filter base are: The electronic steering clutch and brake valve (4) is located on top of the main case. Shown to the right is; (A). Right steering clutch solenoid (B). Right brake solenoid (C). Left brake solenoid (D). Left steering clutch solenoid A through D are proportional solenoids (E). parking brake solenoid (F). secondary brake solenoid E and F are ON/OFF solenoids Four pressure test ports (C1, B1, B2, and C2) They coincide with the order of the clutch and brake solenoids. . The torque converter output speed sensor (A) is located above the torque divider output shaft. The 6-micron torque converter charge filter (K) is located at the upper right, rear of the main case.
