Modular PCB Conveyor System 3.6.6 Replacing the Toothed Belt of the Drive Unit [00355553-xx]
160 Service Manual SIPLACE X Series
Installation
► Install the shim/washer (7) and the circlip (8).
► Loosely fasten the DC geared motor (5) with the four M3 hexagonal socket-head screws (6). The
entire width of the toothed belt must engage at the top and bottom toothed disks.
► Tension the toothed belt (1) by moving the DC geared motor in the fastening holes. The belt tension
must be between
10 and 15 N.
► Fit the drive unit as described in "3.6.2 Replacing the Complete Drive Unit [00359284-xx]" [ ➙ 152].
CAUTION!
Do not damage the toothed belt!
The toothed belts must not be stretched or kinked!
► Insert the new toothed belt (1) into the motor mount
(2) and place the belt around the toothed disk (3) of
the geared motor.
► Place the toothed belt around the toothed disk (4) of
the conveyor toothed belt and insert the toothed disk
in its mount.
► Use a rubber mallet to carefully knock the toothed
disk into position.

Parts
For item numbers and the designation of the respective toothed belt, please refer to the spare parts cat-
alogue.
Overview
Removal
► Move the PCB conveyor to the position which gives you best access to the conveyor belt
► Move the Y gantries into the area outside the PCB conveyor.
► Switch off the machine and secure it to prevent unauthorized reactivation.
NOTICE!
The following diagrams apply to the standard conveyor
system (fixed side - right). Depending on the conveyor
edge (right or left) either the mount or the drive unit will be
fitted.
1. Input conveyor
2. Placement area 1
3. Intermediate conveyor
4. Placement area 2
5. Output conveyor

CAUTION
Do not damage the toothed belt!
The toothed belts must not be stretched or bent!
The minimum radius of the toothed belt is 16 mm.
1. Tape drive (mount)
2. Deflection pulley with slot
3. Conveyor toothed belt
The way in which the conveyor toothed belt is run around
the deflection pulley depends upon the transport area
concerned. Please observe this belt guidance during as-
sembly and disassembly. Please also bear in mind the
following differences during assembly and disassembly:
▪ The drive unit is installed at an angle (tilted), accord-
ing to the requirements of the installation site.
▪ Depending on the conveyor cheek, either the tape
drive (mount) or the DC drive motor will be installed.

Modular PCB Conveyor System 3.6.7 Replacing the Conveyor Toothed Belt (2.5 mm Width)
162 Service Manual SIPLACE X Series
Installation
► Loosen the deflection pulley (2) with the slot and re-
lieve the tension on the conveyor toothed belt (3).
CAUTION!
The deflection pulleys have been assembled with sliding
nuts.
The screw for the deflection pulley should only be loos-
ened! If the screw is removed, the sliding nut will fall be-
hind the conveyor cheek side cover. You then need to
dismantle the cover to retrieve the nut.
► Loosen the three screws fastening the drive unit or
tape drive (holder), so that this can be moved on the
hexagonal shaft.
► Carefully pull off the tape drive (mount) (1) or the
drive unit, while also gently unthreading the conveyor
toothed belt (3).

CAUTION
Check the toothed belt before fitting it.
► Hold the toothed belt between two fingers and let it hang down. The toothed belt should be
roughly O shaped and when hanging freely may not turn by more than 90°!
CAUTION
Do not damage the toothed belt!
The toothed belts must not be stretched or bent!
The minimum radius of the toothed belt is 16 mm.
► Feed the new conveyor toothed belt (2) into the drive
unit and weave it round the deflection pulleys (3).
► Insert the tape drive (mount) or drive unit (1) with the
conveyor toothed belt (2) and fasten.
NOTICE!
When replacing the belt on the passive side (tape drive
without drive unit), set the track width to 50 mm. The tape
drive must be aligned towards the active side, allowing
smooth axial movement of the hexagonal shafts.
► Tighten the fastening screws.
► Adjust the belt tension.
