Attach the pinion on the mo-
tor shaft. The delivered pinion
is normally 20T with 6mm
shaft. There are also pinions
with 8mm hole available, also
pinions from 15-22T with 6mm
shaft and from 18-22T with
8mm shaft. If the motor shaft
has no fl at spot then add one
at the end of the shaft (mark
the position before, pinion
should be 0.5-1mm away from
the lower motor carrier plane).
Tighten now the grub screws
M4x5 D35, beginning with the
one on the fl at spot.
Now install the motor using
four hex screws M3x8 and
washers 3mm 002 using Locti-
te. The plastic gear wheel is a
high temperature high tech po-
lymer that is uncritical against
any heat. You should feel a
small but noticable play bet-
ween pinion and gear wheel.
For 21 or 22T pinions you must
fi le the long holes 0.5 or 1mm
to the front using a needle fi le.
During mount press the motor
down that it is really vertical.
