LOCATIONS AND DESCRIPTION OF MAJOR COMPONENTS.
The XT--1410--4 transmission contains the following major components. They are keyed to Major Transmission Com-
ponents. The transmission consists of:
Torque Converter Housing
. The torque converter housing is cast iron and is the front member of the transmis-
sion. It has an engine flange at the front and its rear surfaces bolts to the transmission housing. It houses and
supports the lockup clutch, torque converter, input--pump drive gears, and input--pressure and scavenge pumps.
Its rear side supports the high and intermediate range clutches. Its top provides for mounting the oil filters, steer
pressure regulating valve, and the cooler bypass, lubrication, and converter pressure regulating valve, and the
cooler bypass, lubrication, and converter pressure regulator valve assembly.
Transmission Housing.
The transmission housing is cast iron. It houses and supports the range gearing, low
and reverse range clutches, output bevel gears, steer gears, and drive shaft. The transmission services both oil
sump and oil reservoir. The oil sump is the area in which oil is maintained at the most efficient level for transmis-
sion operation. The reservoir is an area separated from the sump and serving, as its name implies, to hold a res-
ervoir of oil. The front of the housing provides the mounting surface for the torque converter housing. The top
surface provides for mounting main and steer control valves and inspection and access cover. The side of the
housing provides for mounting the right and left steer clutch housing assemblies.
Steer Clutch Housing Assemblies
. Each steer clutch consists of:
Internal splined clutch plates
Pressure plate
External splined clutch plates piston
Drive gear
Piston
Hub
Clutch apply ring
Housing assembly
The housing mounts onto the sides of the transmission housing. The transmission housings also serve as a mounting
for the output reduction gear assemblies:
Coupling assembly
Internal splined brake plates
Sun gear
External splined brake plates
Carrier assembly
Brake movable cam ring assembly
Ring gear
Saddle
Output shaft
