Threaded joints secured with liquid locking compound
can be slackened off easily after heating them up to
around 200 °C.

Lock collar bearing
Lock collar bearings are arrested on the shaft by twist-
ing the eccentric ring over the inside bearing race.
Before inserting, it is useful to apply some semi-fluid
lubricant of NLGI class 00, e.g.
CLAAS AGRIGREASE LC 00 / 000 to the inner race
and the shaft to enable easier dismounting of bearings
at a later date.
Always arrest the eccentric ring moderately in direction
of rotation of the shaft and lock it with a set screw. To
loosen the bearing, drive off the eccentric ring against
the sense of rotation of the shaft.

Adapter sleeve bearing
Adapter sleeve bearings do not require a specially
machined bearing seat. They may be mounted on any
drawn or scalped shaft. This is an advantage because
it allows the shaft to be axially moved as required to
obtain correct alignment.
Always install adapter sleeve bearings according to
the conical inside ring. Clean the taper lock adapter
sleeve and the shaft and check that the sleeve nut
runs easily so the taper lock adapter sleeve will not
turn on the shaft when tightening.
Tightening:
First tighten the sleeve nut to the point where the taper
lock adapter sleeve has no more play and is under
slight preload. Now tighten the nut by approx. 90° and
continue turning until the next nearest slot fits the tab.
Secure sleeve nut with the tab.
Slackening off:
Slacken off the released sleeve nut for some turns only
for the time being. The thread must still be fully load-
bearing. Loosen the taper lock adapter sleeve with
a sharp blow, using a block-ended tube.

Ferrule fittings on hydraulic lines
When pre-assembling the unit and for pre-assembled
factory-delivered ferrule fittings, the following applies:
installation is in the associated, well-oiled threaded
joint with half a turn of the union nut beyond the point
where resistance is felt.
Pre-assembly:
– Cut the tube at a right angle.
Do not use a tube cutter! This would cut the tube
wall at an angle and would cause a significant
amount of burr lines on both the interior and
exterior.
