Taper ring fasteners
Conical ring assemblies represent a safe connection,
even if high forces are transferred from the drive com-
ponent to the shaft and vice-versa, as long as the
prestressing is correct.
During installation, it is important that the shaft, hub,
sunk keys and tapered rings be carefully cleaned
and then greased with gearbox fluid grease, NLGI-
class 00,suchas:CLAAS AGRIGREASE LC 00 / 000,
and then assembled in the correct order and tightened
to the recommended torque.
Dismantling:
After unlocking the axial stop, release the tapered ring
assembly with a driver tube, applying a firm and clean
strike.
85677
Gib head key joints
Prior to installation, the shaft, the hub and the keyway
must be cleaned so they are free of grease, paint and
rust.
When delivered as a spare part, the gib head key is in
its raw condition, it is therefore too high and would
stick out too far after arresting it. Consequently the gib
head key must be matched to the component in ques-
tion by milling or grinding of the bottom face so that it
will not stick out more than necessary after arresting,
but can still be dismounted perfectly using the CLAAS
special tools (straight or cranked key extractor). The
conical top face must not be machined. Treatment
with a file is not recommended.
Caution!
Sticking on tapered ring assemblies.
–Never mount parts using thick lubricating
grease.
Warning!
Damage to the taper ring fastener.
– The inside diameter of the block-ended
tube must be large enough to extend over
the tapered ring.
Caution!
Damage to the gib head key joint.
– Arrest the gib head key with a suitable
hammer that is not too heavy and with the
right touch.

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.
14029
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.
14031
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.

Threaded joints secured with liquid locking compound
can be slackened off easily after heating them up to
around 200 °C.
14033
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 indirection
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.
14035
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.
14037
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.

– Lightly deburr the interior and exterior tube ends.
Do not chamfer!
– Clean the tube ends.
If the tube is angled, the straight edge of the tube lead-
ing up to the beginning of the curve's radius must be at
least twice as high as the box nut.
– Push the box nut and the cutting ring onto the
tube.
– Press the tube against the stop on the connection
sleeve and tighten the box nutuntil the cutting ring
surrounds the tube.
The tube must not turn during this process. This
may easily happen due to a significant increase in
force.
– Tighten the box nut a 1/2 turn beyond the resist-
ance point.
– Check the notch on the cutting edge.
A visible raised shoulder must fill the space in
front of the front surface of the cutting ring. The
cutting ring can turn, but may not shift axially.
Final assembly
– Fit the pre-assembled tube in the well-greased
threaded connector.
– Tighten the box nut until the resistance point is
felt.
– Tighten another 1/2 turn beyond this point.
Repetitive assembly
– After each time the cutting ring bolt connector is
loosened, the box nut must be re-tightened using
only the minimum amount of force necessary.
Unsealed cutting ring bolt connector
– If the connector is not sealed, it is necessary to
first loosen the box nut until a small amount of oil
flows out.
– Then re-tighten as directed. 14039
Progressive ring fittings on hydraulic lines
When pre-assembling the unit and for pre-assembled
factory-delivered profiled ring 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 clearly 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.
– Lightly deburr the interior and exterior tube ends.
Do not chamfer!
– Clean the tube ends.

Repetitive assembly
– After each time the profile ring bolt connector is
loosened, the box nut must be re-tightened until
the resistance point is felt, before receiving a fur-
ther 1/2 turn.
Important: hold the threaded connector using a
spanner!
Unsealed profile ring connector
If the connector is not sealed, it is necessary to first
loosen the box nut until a small amount of oil flows out,
then re-tighten as directed.
The discrepancies in tightening values reduce the
resulting nominal pressure and the lifespan of the bolt
connector. This leads to leaks and tube slippage.
14041
Taper fittings on hydraulic lines
Installation:
– Apply some oil to the O-ring on the sealing cone.
Tighten the union nut a third of a turn beyond the
point where resistance is felt.
Important: Back up the threaded joint with a
wrench!
Any deviating tightening torques reduce the rated
pressure resistance and the service life of the screw
fitting. This results in leaks and the tube slipping out.

Hydraulic hoses
Hydraulic bolt connectors:
Follow the final assembly guidelines:
– Cutting ring bolt connectors on the hydraulic
ducts, see above. Progressive ring bolt connec-
tors on the hydraulic ducts, see above. Biconal
ring bolt connectors on the hydraulic ducts, see
above.
Hose routing:
Follow the relevant specifications concerning the five
following illustrations.
– Avoid twisting the hoses during installation.
A = incorrect installation
B = correct installation
– Install hoses so that neither tractive force loads
nor upsetting loads occur with short lengths in any
operating status.
C = Wrong installation
D = Correct installation
– Rule of thumb: When jiggling on the hose in the
middle between two brackets/connectors (e.g.
clamps), the entire play of the hose should be at
least 1 cm.

Avoiding external damage:
– Avoid external mechanical effects on hoses
at (G).
– Avoid chafing of hoses against one another or
against components by ensuring useful arrange-
ment and fixing.
– Keep a sufficient clearance from components (H).
– Cover up sharp-edged components permanently.
E = incorrect installation
F=correct installation
Avoiding torsional loads:
– When connecting a hose to moving parts, avoid
twisting the hose, especially when the movement
and the bending occur in the same plane.
K = incorrect installation
L=correct installation
Protection against external heat sources:
– In case of large external heat source:
- Hoses must be kept at a sufficient distance
from heat-emitting parts.
- By default, hoses must be protected from the
heat source by a deflector (N).
14047
Some advice for speedy and correct repair
work
– Mark machine parts prior to disassembly to
ensure their correct left-to-right positions and bal-
ance when reassembled.
– Fit expansion pins with the slot facing the side
under load. When fitted with a quarter turn from
this position, they will get loose, fall out or shear
off.
– Replace split pins, locking wires, locking plates,
tab washers and lock washers when carrying out
repairs.
– Install greasable ball and sliding bearings with the
grease specified for them.

Tightening torques for metric fine threads
The tightening torques specified below apply only
when:
– A friction coefficient of µ tot = 0.14 is achieved in
connection with thread lubricant.
To achieve this, a surface protection agent such
as A3C+L, Dacromet or Termosil is
recommended.
– No other tightening torque is specified in the
descriptive text.
– No additional screw retention is used, such as
MK-type bolts or liquid locking compound.
