At closed WK, the slip between impeller and turbine wheel, and with it the hydraulic loss in
the converter is equal to „Zero“ (see Figure-No. 1.2 B1).
The WK will be automatically shifted dependent on the turbine speed.
The pressure oil (15 + 1 bar) for the closing of the WK, is directed via a solenoid shift valve
(see Figure-No. 1.1 B2) to the piston (6), which is compressing the plate pack.

1.3 Powershift transmission
The multi-speed reversing transmission in countershaft design is power shiftable by hydrauli-
cally actuated multi-disk clutches.
All gears are constantly meshing and carried on antifriction bearings.
The gear wheels, bearings and clutches are cooled and lubricated with oil.
The 6-speed reversing transmission is equipped with 6 multi-disk clutches.
At the shifting, the actual plate pack is compressed by a piston, movable in axial direction,
which is pressurized by pressure oil.
A compression spring takes over the pushing back of the piston, thus the release of the plate
pack. As to the layout of the transmission as well as the specifications of the closed clutches
in the single speeds, see Table-1, 4 and 5.
1.4 Transmission control:
Transmission control, see Schedule of measuring points, Oil circuit diagram and Electro-
hydraulic control unit Table-4, 5 and 9.
The transmission pump, necessary for the oil supply of the converter, and for the transmission
control, is located in the transmission on the engine-dependent input shaft.
The feed rate of the pump is Q = 85 l /min, at n

.
This pump is sucking the oil via the coarse filter out of the oil sump and delivers it via the ZF-
Fine filter – the filter can be fitted also externally from the transmission – to the main pressure
valve.
If because of contamination, resp. damage, the through-flow through the ZF-Fine filter is not
ensured, the oil will be directly conducted via a filter differential pressure valve (bypass valve
∆
p=5,5+3 bar) to the lubrication.
In this case, an error indication is shown on the ZF-Display.
