CUTTING HEAD
Blade shaft bearing housing
The bearing housing carries dual ball bearings for the blade's drive
shaft.
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.

unit fully from the housing.

Remove the bearings using a universal puller.
Bearing replacement
Tools
To replace the blade shaft bearings you need tool kit

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
