Claas QUADRANT 2200, Руководство по ремонту

Страница: 8 / 31

GENERAL NOTES ON REPAIR
1. Identify the cause of the damage. Close off the
area around the incident and make sure the
machine is safe.
2. Only carry out work on the large baler when the
tractor motor has been switched off and the
ignition key removed.
3. Use original CLAAS replacement parts and the
appropriate CLAAS special tools.
4. When removing the gearbox, first drain off the oil
and only then remove the gearbox. Use a
soft-headed or plastic hammer to separate parts
which are tightly interlocked with each other.
5. Tighten up the steel roller chains
The steel roller chains are correctly tensioned if
the return trace can be pushed down by the
thumb in the middle between the chain sprockets
by about 2% from each axle offset, when the
pulling trace is under a light load. For new
chains, check the tension more often.
E xample: Axle offset 5 00 mm - distance moved
by pushing down on the return trace is about 10
mm
6. Self-locking bolts
(with micro-encapsulated adhesive coating)
R eplace self - locking bolts, such as V erbus -P lus /
lmbus -P lus or others every time you assemble
parts. In exceptional cases they may be re-used
up to three times. Take care always to apply the
stated tightening tor q ue.
With self - locking bolts with micro - encapsulated
adhesive coating, always q uickly tighten them up
to the stated tightening tor q ue. When removing
these bolts always q uickly screw them out
completely.These self - locking bolts must not
come into contact with any packing compound
(e.g. » E pple 3 3« or similar).
Bolts with li q uid - type locking may be used
instead of self - locking bolts in individual cases,
but only where the bolted connections can be
heated up to ca. 2 00 °C in order to loosen them.
Take care to use the specified grade of bolt here
as well (8.8/ 10.9 or other).
Self-locking bolts with micro
- encapsulated
adhesive coating can only be used where the
operating temperature does not exceed a
maximum of + 9 0 °C.
Q UAD R A N T 2 2 00 / 2 2 00 R C
General notes on repair
The full load capacity of these bolts is reached
after 2 4 hours at a temperature of + 2 0 °C.
The time to achieve full load capacity can be
shortened by heating (e.g. at+ 7 0 °C for
1 5 minutes).
7. Liquid bolt locking
(e.g. Delo - ML 18 7)
Only use bolt locking li q uid where specified by
the manufacturer.
Correct use:
Metal connections which are to be fitted using
bolt locking li q uid must be completely clean of
grease. Clean the parts with the »Activator«
which comes with the workshop pack.
Clean and dry the Activator from the metal
surfaces before applying the bolt locking li q uid.
In particular, make sure that there is no residue
of Activator (cleaning agent) remaining in any
blind holes.
For bolted connections the bolt locking li
q uid
should only be applied to the internal (mother)
threads, and in small amounts (drops). For blind
holes, only wet the threads for a distance of ca.
1 x d (d = nominal diameter of the screw bolt).
Do the same for all overlong screw threads. If
the bolt locking li q uid is applied to the threaded
bolt or to the start of the thread for screw in
threads, then when the piece is screwed in the
li q uid will spread over the whole length of the
thread. When later attempting to loosen it later,
the breaking moment will be too high - there is
a risk that the bolt will shear off.
Bolted connections which have been secured
using bolt locking li q uid can be easily loosened
by heating them up to ca. 2 00 °C.
8. Fitting the lock ring bearing correctly
Lock ring sleeve bearings are fastened to the
roller by turning the eccentric ring over the
bearing inner ring on the shaft.
Before fitting, coat the inner ring and the shaft
with viscous gearbox oil type N L G I - Class 00
(e.g. Shell R etinax G or other), so that the
bearing can removed more easily should the
unit have to be disassembled later.
Always lightly hammer the eccentric ring tight
in the turning direction of the shaft, and lock with
a grub screw. To loosen the bearing, free the
eccentric ring by hitting it against the turning
direction of the shaft.
