4 Replacing spare parts at the conveyor
4.5 Conveyor belt, belt drive and hexagonal shaft
72 Service Manual ASM ProcessLens Dual-lane 09/2018
Removal
CAUTION
Toothed belt
► Make sure that the toothed belt is not folded or otherwise damaged.
► Use the software or manually move the conveyor rail into a position which allows you best
access.
– To move the conveyor rail manually, pull the toothed belt of the width adjustment unit.
– Make sure that the rear side of the conveyor rail is also accessible.
► Switch off the machine, disconnect it from the power supply and secure it to prevent
unauthorized reactivation.
Fig.48: Movable idler pulleys
► Loosen the fixing screw of the relevant movable
idler pulley(1) to release the tension of the belt.
CAUTION!
Loosen the movable idler pulley only as far
as necessary!
Do not remove the movable idler pulley (unless
you explicitly need to remove it). Otherwise the T
slot nut on the inner side fall into the conveyor
rail.

► Remove the fixing screw(1) (cross head) and
take off the washer(2).
► Remove the toothed belt(3).
► Remove the fastening screw(4) (Allen).

Fig.50: Pulling out the pinion gear drive
► From the rear of the rail, push the pinion gear
drive out.
Fig.51: Pulling off the bearing
► Pull the bearing(1) off the pinion gear drive.
Installation
Fig.52: Inserting the bearing
► Insert the bearing(1) into the rail.
Make sure that the bearing does not fall into the
rail.

Fig.53: Inserting the pinion gear drive
► Insert the pinion gear drive.
Fig.54: Screw
► Secure the pinion gear drive with the screw(1)
(Allen, DIN EN ISO 7380-M3x4-A2-70
[03074775‑xx]). Tighten the screw with a torque
of 0.58Nm.
CAUTION!
Make sure that you do not tighten the screw
too much. This could cause irreparable dam-
age to the conveyor!
The corresponding threads are only in 1.5 to
2mm thick plates and could be damaged if you
use a torque which is too high.
For this reason, avoid using screws which are
too short. Use a measuring scale to check, if
needed!

Fig.55: Screw
► Thread in the toothed belt(3).
Make sure that the toothed belt is positioned ac-
curately in the guidance on the motor shaft or in
the belt drive.
► Fix the washer(2) with the screw(1) (cross
head).
► When you tighten the idler pulley, set the tension of the toothed belt.
