General repair instructions
In individual cases, bolts with liquid locking compound
can be used instead of self-locking bolts only where
these bolts can be heated up to approx. 200 °C for
removing them. Here as well, the specified quality
grade of bolts (8.8/10.9 or similar) must be observed.
Self-locking bolts with micro-encapsulated adhesive
may be used only where operating temperatures will
not exceed +90 °C max.
These bolts can be subject to full stress after 24 hours
at +20 °C. The period required for complete curing can
be reduced by heating up (e.g. to 15 minutes at
+70 °C).
Liquid locking compound
(e.g. DELO-ML-5328)
Attention!
Use liquid locking compound only where
specified by the manufacturer.
Correct application:
Metal surfaces where liquid locking compound is to
be applied must be absolutely free from grease.
Use the "Activator" included in the workshop package
for cleaning.
Before applying the liquid locking compound, the acti-
vator must have dried on the metal surface. Especially
in blind holes, no activator (cleaning agent) residues
are allowed.
On threaded assembly, apply the liquid locking com-
pound only on the internal thread (nut) if possible and
in small quantities (drops). In blind holes only wet
approx. 1d (d = nominal diameter 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.
Proper installation of lock collar bearings
Lock collar bearings are tightened on the shaft by
rotating the eccentric ring over the inside bearing ring.
Before inserting, apply some semi-fluid lubricant of
NLGI class 00 (e.g. CLAAS semi-fluid lubricant EP 00,
part no. 147 455.1) to the inner ring and the shaft so
that the bearings will be easier to remove if required in
the future.
Always fasten the eccentric ring moderately in the
direction of rotation of the shaft and lock by means of a
set screw. To remove the bearing, loosen the eccentric
ring in opposite direction of rotation of the shaft.
Proper installation of 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:
Now slacken off the unlocked sleeve nut by 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.
