Checking toothed rod for scoring
If corroded areas or deep scratches are not
noticeable on the toothed rod, the toothed rod must
be replaced
An evaluation of whether the toothed rod was
damaged by force, e.g. by an accident, is not possible
with this visual inspection
If slight scoring (arrows) can be seen/felt on the
toothed rod that are only deep enough that they can
be ground off with sand paper (grain 350-600) the
toothed rod can still be used
After sanding, lubricate toothed rod lightly
If the old toothed rod is used again, check the sealing
ring for scoring (visual inspection). If there is scoring
that can be seen or felt, the sealing ring and the O-
ring under it must be replaced.
