Start with the assembly of the upper
frame. Join the frames H1 and H2, the
bearing blocks H3 (2x) and H4 with hex
screws M3x35 D338, countersunk screws
M3x35 D324 and lock nuts M3 008 to-
gether.
It is not necessary to sand chamfers on
the edges of the frames as they are alrea-
dy smooth and it may result in scratches
on the surface of the carbon.
Two countersunk screws M3x35 D324
are inserted through the upper two holes
of the left frame and the bearing block
H03 and with bearing
fl
ange upwards
slide onto the screws. Also
fi
t the two hex
screws M3x35 D338 and the lower bea-
ring block H03 with bearing
fl
ange down-
wards and slide onto screws. Then place
the right frame H02 on to the screws and
loosely
fi
t the 4 lock nuts.
Put the motor shaft bearing block H04
between the frames and secure it with two
screws M3x35 D338 and loosely
fi
t lock
nuts M3 008.
Loose means that the nut will be tightened
to be in contact with the frame so that the
frames are still movable for
fi
nal align-
ment.
For a perfect
fi
t of the three bearing
blocks, press the two mainshaft bearings
downwards/upwards during tightening of
the screws. When all screws are tightened
check the alignment of the frame edges,
especially the lower edges.
