Install the drive shaft
Hold the drive shaft on the underside and screw in the tool's screw, through
the triangle, into the base of the shaft.
Pull in the drive shaft using the nut on the tool until the shaft comes into
contact with the domed underside of the triangle. Note that the triangle is to
be turned to support the bearing.
Bearing assembly final inspection
Following bearing assembly check that the upper bearing is completely in
contact with the chassis. The correct position of the bearings in the chassis
means that the pulley and blade drive wheel are correctly aligned with the belt
and cutting blade.
Assembly problems
If the inner bearing has dropped when the outer bearing was installed then a
complete reassembly must be carried out. In that case the solution is to use a
washer as a support when the outer bearing is assembled as well.
Unfortunately this is an inferior method as a non-uniform load is placed on
the inner bearing between the bearing rings when the spacer ring comes into
contact with both bearings. The assembly of the outer bearing must be inter -
rupted just when the spacer ring met both bearings – in other words just when
the resistance increases. Before assembling the shaft check that the spacer ring
is located between the bearings with no play.
Under no circumstances can the position of the bearing package be
adjusted by hitting it with a hammer. This will always lead to bearing damage.
Replace the radial seal
Replace the radial seal with a new one. Press out the old seal in any direction.
Place the new seal on a flat surface with its spring side up. Push down the
holder until it comes into contact with the surface.
Note that the spring side of the radial seal must be face down in relation to
the bearings during assembly.
Reinstall
Grease the O-ring and fill the radial seal
internally with grease.
Note that the wear ring has a bevel
which is to face upwards. The wear ring is
first lubricated and mounted on the shaft,
then the radial seal is fitted with the hol-
der.
Install the other parts.
