Fit radial seal (16) onto the side a of the insertion sleeve 119 589 01 14 00 and draw in as far as the stop with bolt (11) and 4 Belleville spring washers (11a).

The radial seal (16) must be at right angles to the hub otherwise it will not provide a proper seal.
If the hub has running scores, position radial seal (16) 3 mm offset to the inside.
To do this, fit radial seal (16) onto the side b of the insertion sleeve 119 589 01 14 00 and draw in as far as the stop.
