7.11.4 Exchanging the wear flange
303
7 Maintenance and Care
The distance between two wear flanges amounts to approx. 0.5 mm for a new machine.
When this distance becomes too great, more grass, weeds and beet leaves, etc. get
caught at the transition to the next conveyor.
ROPA recommends replacing the wear flanges when the distance amounts to 2-3 mm.
This exchange is easy to perform. The settings of the taper roller bearings are left totally
untouched since they are behind the wear flange.
The fundamental procedure corresponds to that for removal of pinch rollers with the
difference that the fine thread bolt (16) must be slackened first (do not completely
unscrew it).
In order to exchange the wear flange, (28), only the fastening bolts 29)
of the wear flange need be replaced. If the two grub screws (30) are screwed into the
thread, the wear flange is forced off.
Two versions of wear flange are required:
