Trouble shooting the torque converter
One prerequisite for the function of the power assisted steering is the play in the steering.
This play must always spring back to the starting position when the wheel is released.
Test by slowly turning the wheel in one direction when the engine is switched off. At first
there is a slight resistance, which increases when the machine begins to turn. Release the
wheel. It should now return to the middle position.
The wheel should spring back approx. 10-20 mm when the wheel is released after turning.
However, the machine will not automatically "drive straight forward" after turning in the
same way as a car.
If the machine always turns in the same direction as soon as the engine is started, there is
probably a fault in the torque converter.
Note!
If the steering does not function this does not mean that there is always a fault in the
torque converter. Faults can also occur in more simple mechanical parts such as
chains and gear wheels.
