➢ Fasten the new motor to the motor flange and follow the instructions for removal in reverse

order.

➢

Support the motor from below and loosen the

screws fastening the motor flange at the points

marked 1 to 3..

NOTICE

Screw joints difficult to loosen

Each screw joint has an O-ring seal. This can make opening the screw joint difficult.

Use a pair of water pump pliers to help you unscrew the connection.

Make sure that the O-rings do not fall out of the screw joint and that they are not damaged.

3.5.3 Replace the Load Axis Drive Toothed Belt

➢ When installing the motor, make sure that it is aligned parallel to the slide bar.

➢ Readjust the belt tension (see "3.5.6 Setting the Load Axis Belt Tension" [➙ 3-44]).

Spare Part

• Toothed belt 10T5/1640 E [03053795-xx]

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 from the non-stop module (see "3.5.1.1 Remove the Cover on the Load

Unit" [➙ 3-33]).

➢ Remove the hand guard from the feed axis (see "3.5.1.2 Removing the Right Side Cover

from the WPC" [➙ 3-33]).

Removal / Installation

➢ Relax the belt by loosening the two fastening screws (1) sealed with locking varnish, at the

tensioning device with the deflection pulley (2).

➢ Loosen the four screws fastening the driver unit (3). The clamping unit for the toothed belt is

located underneath this.

➢ Carefully remove the driver unit. 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 (2), so that you can feed in the new

toothed belt more easily. To do this, loosen the two fastening screws (1).

➢ Insert and run the toothed belt from the tensioning device (1) to the deflection pulley (4). The

toothed belt should exit below the bottom deflection pulley (4).

➢ Place the one end of the toothed belt around the deflection pulley (4) and insert into the

clamping unit (5).

➢ Place the other end around the deflection pulley of the tensioning unit (1) and then insert

into the clamping unit (5) from the other side.
