ADJUSTEMENT METHOD
The clearance adjustment of the pusher is performed by tightening the threaded plug at the
required moment of 1+/-0,2 daNm and unscrewing it ˘ round.
The moment for the gear rotation will be
about 0,15 daN.m (maximum accepted 0,25
daN.m ) on the whole length of the rack or
the rack gliding effort of 25 daN (maximum
accepted 40 daNm ) without rigid points.
