Introduction
General repair instructions
81213
Never use force for arresting the gib head key in order
to avoid damage to the components (especially the
brake discs) and to enable loosening with the CLAAS
special tool.

Self-locking bolts with micro-encapsulated
adhesive
Replace all self-locking bolts, e.g. Verbus-Plus and
Imbus-Plus, every time when removing them. In
exceptional cases, such bolts can be reused up to
three times.
Always tighten self-locking bolts with micro-encapsu-
lated glue quickly to the specified tightening torque.
Always observe the specified tightening torque.
When unscrewing self-locking bolts, unscrew them
quickly. Self-locking bolt must not get in contact with
sealing compound.
Self-locking bolts with micro-encapsulated glue can be
used only in locations where the operating tempera-
ture will not exceed
+ 90 °C
.
The full load capacity of these bolts is achieved after
24 hours at
+ 20 °C
. Full hardening can be accelerated
by heating-up, e.g. to 15 minutes at
+ 70 °C
.
In specific cases, bolts with liquid locking compound
can be used instead of self-locking bolts only where
such threaded joints can be heated up to around
200 °C
for slackening off. The specified bolt quality
grade, e.g. 8.8 or 10.9, must be observed here as well.

Liquid locking compound
Use liquid locking compound only where this is speci-
fied by the manufacturer.
Proper application:
Metal joints intended for liquid locking compound use
must be absolutely free from grease. Clean such joints
with the "Activator" enclosed in the workshop package.
Before applying the liquid locking compound, the acti-
vator (cleaning agent) must have dried on the metal
surfaces. No more activator residues may be present,
especially in blind holes.
Apply the liquid locking compound of threaded joints
only to the inside thread of the nut drop by drop if pos-
sible. In blind holes, wet only around 1 d (d = rated Ø
of threaded pin) at the thread bottom. Proceed in the
same way with all excess-length screw threads. When
applying the liquid locking compound on the threaded
bolt or at the beginning of the screw thread, it will
spread over the entire thread length while screwing it
in and the breakaway torque is too high when slacken-
ing the bolt off later – danger of bolt tearing.
