All repair and maintenance of the Levelflex must be carried out while the
packer is securely placed on the ground and thus rests safely on the base.

It is extremely dangerous to stay underneath the Levelflex before the imple-
ment is supported properly. If the packer is attached to the tractor, it is impor-
tant that the tractor is braked properly.

When changing the bearings, shafts and rings, the frame head must be
supported by a solid support. However, it is recommended that the Levelf-
lex is mounted in the tractor's three-point linkage with the Levelflex resting
on the base. When repairing the side sections (hydraulic models), the sections
must be lowered and rest on the base.
Replacement of bearings/shafts/rings
The procedure for replacing bearings and shafts depends on the model and the
type of ring. Due to normal tolerances on the casting, washers might in some
cases be placed between the bearings and the rings and also between the lock-
ing screw of the shaft end and the outer ring. It depends on the new rings
whether the washers can be used again or not, as the rings must be firmly
fixed but only to the extent that the lock washer (plate 9) can be tightened as
close as possible to the shaft end. There must be no air between the lock
washer and the shaft end since the lock washer must press against the shaft
end.
If the rings are difficult to pull off the shaft, try using a high pressure cleaner
to wash between the ring and shaft in order to remove fixed rust and soil. If
the repair is not an urgent matter, the shaft can be placed in an upright posi-
tion and derusting liquid can be applied, where after the shaft with the rings
are left through the night.
A ring can be so tight that it is necessary to cut through the shaft and thereaf-
ter the ring can be pulled off in a hydraulic press. This requires a new shaft, as
the old shaft cannot be welded together again. If there is only one solid ring,
then it will be more economical to cut it through with an angle grinder and
thereby spare the shaft.
When the bearings are mounted on the shaft, it is important that the pro-
truding shaft ends are of equal length on both sides.
