First assemble the blade holder with all bearings.
Attention!
To avoid any mistake it is important to follow a specific
sequence. Both of the radial bearings
0113
, which are pointing toward the center hub, are pressed into each blade
holder. If necessary
,
expand the blade holder with hot air. Make sure not to insert the bearing aslant. Now insert the axial
bearing
0115
through the fork of the blade holder. Apply enough lubricant onto all parts of the axial bearing in advance
(viscose grease into hollow side of ball cage). Pay attention to the correct sequence as displayed in the drawing. Each
ring has to be inserted laterally through the fork. At the beginning of the fork where the bore of the blade holder begins,
the rings are swiveled into rectangular position and pushed into the bore. Make sure the rings do not swivel by 180° and
carefully reassure that the grooves of the rings always point to the bearing balls. This procedure can be simplified with the
aid of a pin inserted from the other side, onto which you may align the rings. The first ring to be inserted has a 8.2mm
inner diameter. Then the ball cage follows with its hollow side pointing toward the center hub. Then you insert the ring
with an inner diameter of 8.0mm, followed by a spacer washer
0107
(8x14x0.2) and finally the radial bearing
0113
.
Attention!
To avoid aslant insertion, the final radial bearing should be assembled as follows.
After the axial bearing
0115
and the spacer washer
0107
are inserted, shove the bearing laterally between the fork and
swivel it into a right position.
If the radial bearing does not enter the blade grip without force, expand the blade holder with hot air. You can also use a
8mm pin to get the bearing aligned to the other bearings.
