Service maintenance manual
8.16 Removal and installation of hopper motor module
8.16.1 Remove the cable tie fixing motor cables to motor of hopper (the motor on the left) (see
Fig. 140 Fig. 141).
8.16.2 Remove lock washer 3 W0001 fixing wheel on motor shaft (see Fig. 142 Fig. 143).
8.16.3 Remove interrupter wheel and cog belt HTD-222-3M-6 (see Fig. 144 Fig. 145).
8.16.4 Remove two screws M4x7 JPM1-407N101 (M4x8 N0021+W0011+W0023/ JPM1-
408N100) of motor fixture to the frame side, remove the motor (see Fig. 146).
Motor module installation and belt tension.
8.16.5 Install the motor module on the frame side wall and fix it with screws M4x7 JPM1-
407N101 not all the way in (see Fig. 144).
8.16.6 Make mounting accessory of interrupter wheel 3М 15T EBKM.00D800.02.00.010 FRZ-
022985 (from spare parts and accessories complete set): cut the wheel side with sidecutters so that it
is a little bit larger than the gear (see Fig. 147).
8.16.7 Install the cut interrupter wheel; install the belt on all the gears (see Fig. 148 Fig. 149).
To control the belt tension EBKM.00D820.П2.00.000 belt tension adjustment jig is used
(see Fig. 150 and Fig. 151).
To control the belt tension install the jig so that its stoppers are flattened against the belt on
the gears properly, ensuring that project of bar is located on the belt approximately in the middle
between the gears and in the middle of the belt. Flatten the stops to the gears collars (see Fig.
152). After the mounting accessory is installed correctly, control visually the bar position against
the scale.
The belt tension is correct if the bar bottom plane is aligned with the scale bottom plane
(scale on the right; see Fig. 153). If the bar is lower, it means the belt is loose (see Fig. 154), if
the bar is higher – the belt is overtensed (see Fig. 155), adjustment is required in both cases.
8.16.8 Loosen the motor fixing screws on 1…2 turns (see Fig. 156), tighten the belt to maximum
(by moving the motor downwards and to the right) and tighten the motor fixing screws. Install the
belt tension control jig (now the belt is overtensed). Simultaneously control the belt tension visually
with the jig and gradually loosen the motor fixing screws; catch the moment when the belt tension
starts weakening. When you get the perfect belt tension (see Fig. 153), tighten one of the motor
fixing screws, then remove the jig and tighten another screw. Control the belt tension with the
accessory again. If necessary the adjustment needs to be repeated. After the counter assembly, control
the motor rotation speed in service mode (see s. 10.1.3.1 “Indirect method for belts tension control”).
8.16.9 Remove the belt and the cut interrupter wheel.
8.16.10 Install the standard interrupter wheel on the motor shaft and fix it with the lock
washer 3 W0001 (see Fig. 143 Fig. 142).
8.16.11 With phase adjustment jig EBKM.00D800.T2.00.007 adjust the necessary phase
angle and install the belt (see Fig. 157 Fig. 158). Remove the jig, test the wheels rotations, and ensure
the belt won’t come off. If the jig is unavailable, install the belt so that Dispensing roller glides and
Feeding wheels glides appear over the hopper surface simultaneously ±1 glide cog (see Fig. 159); the
hopper serves as phase adjustment jig.
8.16.12 Fix motor cables with cable tie ensuring there is no sagging and the cables are not
in contact with any moving parts (see Fig. 160). Cut off the cable tie residue.
