Cotter pin
substitution
If the machine works but the
augers do not turn, it is
possible that the cotter pin,
(item 35 of the exploded view
at pag.39) that connects the
gear motor to the
transmission shaft, broke
down.
Disconnect the power
electric cable
After removing the back and
side panels, you can see the
breakdown trying to lift the
ring that fix the vertical auger
(item 28 of the exploded view
at pag.39).
It can happen that it is
blocked or that, if you lift it, it
carries away the transmission
shaft with it (item 29 of the
exploded view at pag.39)
In the first case, it is
necessary to control that the
transmission shaft base is as
high as the gear motor (exit
shaft). The lift pin could be in
the hole of the gear motor
slow shaft but it should be
deformed or broken (see
pic.a)
In the second case, the hole
in the gear motor should be
completely empty and some
remnants of the split pin will
certainly lie in the machine.
It is therefore necessary to
install a new split pin.
- Place the transmission
shaft so as its hole is
aligned with the one
present on the gear motor
exit shaft; it should be
evident when they are
aligned (see pic.b);
- Insert the split pin as
shown in the pic.c;
- Verify that the head of the
split pin, in its rotation,
does not touch the gear
motor and respects a
minimum distance.
Warning: do not reuse,
in any case, the old split
pin;
- With the help of a pliers,
fold the two ends of the
split pin downward as
indicated by the arrows in
the pic.d;
- Then, with a nippers, cut
the extremities in excess in
order to avoid a contact
with the gear motor during
the rotation (see pic.e).
