Blade shaft bearing housing
K1260 and K1260 Rail have different bearing housings for the blade shaft.
The location of the actual bearings and shaft and bearings, however, is
identical for both bearing housings.
The same method and tools are used for changing the bearings in the two
bearing housings.
Blade shaft, bearings
The blade shaft has a fixed machined spacer which the bearings' inner rings
must be in contact with after assembly in the bearing housing. The bearing's
inner rings are press-fitted against the shaft and the outer rings are press-fitted
against the bearing housing.
It is very important not to expose the bearing to clamping forces between
the inner and outer rings during assembly. With the help of special tools and
assembly methods described here, the bearings are fitted without any risk of
the forces damaging the ball bearings.

Bearing replacement
Tools
To replace the blade shaft bearings you need tool kit
575 96 20-01 if the bearing replacement is made by
hydraulic press. The tools are used for both dismantling
and assembly.
If the hydraulic press is missing, the bearings can be
replaced in the manner described below, in which case tool
kit 506 37 61-02 is required.
Dismantling
Turn the dismantling support A with
shoulder up and put the bearing housing
on the device.
Put the triangle in the tool kit
506 37 61-02 or assembly support B in
kit 575 96 20-01 on top of the bearing.
Press or knock out the bearing unit as
far as possible. Then extend with a
suitable tool socket to push out the
complete bearing unit fully from the
housing.
Remove the bearings from the
axle
Remove the bearings using a universal
puller.
