The swirl or creak of the full rudder turns to the right or to the left arises from the tensioning of the drive belt (hydraulic) steering pump. The problem is solved by adjusting the tensioning of the belt as follows:
1. Key on "13" to weaken the rear and front mounting of the pump;
2. Torx wrench on "8" to weaken the upper anchorage of the pump;
3. The key on "10" to return the adjustment bolt until the desired tension of the belt is reached (when 10 kgf is pressed it shall be 5 to 8 mm), the force can be measured by means of a convoy of approximately 10 kg);
4. After the adjustment is complete, the pump shall be tightened.
To access the GRM, it will be necessary to remove the protection of the crankcase and the right front wheel. Care should be taken when tightening the fastening of the pump bolts because excessive force can lead to breakage of the brackets.
