3.4.4 Replace the Driver Unit
Spare Part:
• Tappet gripper 359 lg cpl. [03069215-xx]
Removal / Installation
➢ Move the driver feed axis with the toothed belt into a suitable position for service work (at
the front, in the transfer area).
➢ Loosen the two screws (1) fastening the cover and remove the cover.
➢ Loosen the four screws (2) fastening the driver unit. The two ends of the toothed belt are
fixed to this.
➢ Carefully remove the driver unit.
➢ Follow the removal instructions in reverse order for installation.
➢ Align the driver unit (see "3.4.4.1 Align the Driver Unit" [➙ 3-24]).
➢ Check the belt tension (see "3.4.6 Setting the Feed Axis Belt Tension” [➙ 3-28]).
3.4.4.1 Align the Driver Unit
The driver unit must be adjusted so that it is straight (adjust at fastening screws). Make sure that
it does not rub against any parts or jam at any point of the travel range.
➢ Set the driver (1) to a distance of approx. 0.5 mm (3) to the white plastic guidance (2).
➢ Push the driver back and forth along the travel range, to check that it does not rub against
any parts or jam at any point.
➢ Set the correct belt tension. See also "3.4.6 Setting the Feed Axis Belt Tension" [➙ 3-28].
➢ Calibrate the feed axis (see "4.2 Calibrating the Feed Axis" [➙ 4-126]).

3.4.5 Replace the Feed Axis Toothed Belt
Spare Part
• Toothed belt 10T5/2120E [03047690-01]
Preparations
➢ Move the tower into the refill position.
➢ Remove all waffle pack tray carriers (WPTCs) from the tower.
➢ Move the tower downwards.
⇨ Check sensors and functions ⇨ Check sensors and functions of specific components ⇨
⇨ Location ⇨ Check functions for WPC ⇨ Move into transport position.
➢ Undock the WPC from the SIPLACE machine and move it to a suitable position for service
work.
➢ Switch the WPC off at the main switch.
➢ Unplug from the power supply and secure the WPC to prevent unauthorized reactivation.
➢ Remove the cover of the NSM module (see "3.5.1.1 Remove the Cover on the Load Unit"
[➙ 3-33]).
Removal / Installation
➢ Move the feed axis driver with the toothed belt into a suitable position for service work (at the
front, in the transfer area).
➢ Loosen the two fastening screws (1) sealed with locking varnish, at the tensioning device
with the deflection pulley (3).
➢ Loosen (do not remove) the tensioning screw (2) - sealed with locking varnish - on the
tensioning device. This relaxes the toothed belt.

➢ Loosen the 4 fastening screws (4) on the driver unit (5). The two ends of the toothed belt are
fixed to this.
➢ Carefully remove the driver unit (5). This toothed belt is now loose.
➢ Note how the toothed belt is run, so that you can fit it again correctly later on. Pull the toothed
belt over the two deflection pulleys (back and front) and out of the WPC.
➢ Remove the tensioning device and deflection pulley (3), so that you can feed in the new
toothed belt more easily. To do this, loosen the two fastening screws (1).
➢ Insert the toothed belt into the WPC at the transfer position and run it from the tensioning
device (1) to the deflection pulley (4). The toothed belt should exit below the bottom
deflection pulley (3).
➢ Place the end of the toothed belt around the back deflection pulley (3) and insert into the
clamping unit (5).
➢ Place the other end of the toothed belt around the deflection pulley of the tensioning unit (2)
and run as far as the clamping unit (5).
➢ Fit the tensioning device with deflection pulley and fix into place with the two fastening
screws.
