4.2.3.1.5 REVERSAL LOCK (LOGIC LOCK OUT)
UP TO 4/94
- Slacken the sealing nut (16.2).
- Using a socket head spanner, screw in the setscrew (16.1) as far as possible and then screw out again
2 1/2 to 3 turns.
- Start the engine, release the brake and fully depress the forward accelerator pedal. The engine and
wheels must accelerate to full speed. When the direction of travel is reversed quickly (reversing), the
engine speed control cylinder is retracted to the bottom end position and held there until the wheels have
ceased rotating. Then the speed control cylinder will be extended fully again.
- Perform the same test with the reverse accelerator pedal.
FROM 5/94
- Valve adjustment with shims (16.1.3).
- Start the engine and carry out the test as for the version up to 4/94.
NOTE: Insert the shims: Reversal lock is advanced.
Remove the shims: Reversal lock is retarded.
4.2.3.1.6 REDUCING THE TRUCK SPEED
The maximum truck speed can be reduced as desired by the customer. For this purpose it is only
necessary to reduce the travel of the control piston (14), which reduces the swash angle of the pump.
CONDITIONS
- Truck jacked up and secured with blocks
- Hydraulic oil at operating temperature
- Start of the primary control and the mechanical stop for the swash angle
ADJUSTMENT
- Loosen the ealing collar nut (11) and turn in bolt (12).
The average RPM of the wheel is reduced by approx. 14.5 rpm, i. e. approx. 2 km/h per turn of th bolt.
