1.6.4 Checking the hydraulic steering limitation
1
.6.4.1 Manually adjustable hydraulic steering limitation
Vehicles with a rigid axle:
Jack the steered axle up. ¡
Vehicles with single-wheel suspension:
Place the wheels of the steered axle on swivel plates.
Rotate the steering wheel clockwise. When the axle stop and the lock stop, respectively, are
reached, continue to rotate the steering wheel until a positive stop is reached.
In this position read the pressure at the pressure gauge:
Specified values:Steering systems up to 16 dm
3
/min: 40...50 bar
u
p to 20 dm
3
/min: 50...60 bar
above 20 dm
3
/min: 70...80 bar
Repeat this test for the other direction of rotation.
Setting the steering limitation: see Chapter III., para. 5.
1.6.4.2 Automatically adjusting hydraulic steering limitation
Carry out the test as described in para. 1.6.4.1.
If there is no more space left at the lock stop components or if the oil pressure does not drop to
the specified value, fit new screws (20) and (128), respectively, and reset the steering limitation
as specified in Chapter III., para. 5.
Specified values: Steering systems up to 16 dm
3
/min: 40...50 bar
u
p to 20 dm
3
/min: 50...60 bar
above 20 dm
3
/min: 70...80 bar
If there is too much space available at the lock stop components and if the oil pressure does not
drop to the specified value, reset the steering limitation as specified in Chapter III., para. 5.
Repeat this test for the other direction of rotation.
