The spreading disc hub must be centred exactly under the agitator.
Figure 9.4: Checking the position of the spreading disc hub
Requirements:
The spreading discs are removed (see “Dismounting spreading discs” sub-
section).
Testing the centring:
1. Use suitable equipment to check that the spreading disc hub and agitator are
centred (e.g. straight edge ruler, protractor)
The axes of the spreading disc hub and of the agitator must be aligned.
They may deviate from each other by a maximum of 2mm.
If this tolerance is exceeded, please contact your dealer or authorised specialist
workshop.
Checking the distance:
2. Measure the gap between the upper edge of the spreading disc hub and the
lower edge of the agitator.
The distance must amount to 136.5 mm (admissible tolerance ± 2 mm).
If this tolerance is exceeded, please contact your dealer or authorised specialist
workshop.
