General repair instructions

In threaded assemblies, apply the liquid locking com-
pound only to the internal thread of the nut in drops if
possible. In blind holes only wet approx. 1d (d = nomi-
nal Ø of bolt) at the thread bottom. The same applies
to any extra-long female threads. When applying the
liquid locking compound to the bolt or at the top end of
a female thread, the liquid locking compound will
spread over the entire thread length when screwing
the bolt in. As a result, too much break-away torque is
required to remove the bolt – Danger of breaking!
Threaded assemblies secured with liquid locking com-
pound can be easily unscrewed by heating them up to
approx.
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 the bearing:
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.
Loosening the bearing:
Loosen the unlocked sleeve nut only by a few turns for
the time being. The thread must still carry the full load.
Loosen the taper lock adapter sleeve with a sharp
blow, using a block-ended tube.
