▪ Z motor with interference suppression board DLM1, DLM2, DLM3 [03038908-xx]
▪ Z motor with interference suppression board DLM4 [03083864-xx]
Removal
Installation
1. 4 x M3x5 hexagon socket-head screws with locking
varnish
2. Z axis drive
3. 2 x M2.5x12 hexagon socket-head screws
4. Motor clamp upper part /DLM3
5. Motor clamp/DLM3 (do not confuse this with the as-
sembly clamp for the Z motor tacho interference sup-
pression board)
6. 2 x M3x14 hexagon socket-head screws
7. Toothed belt
► Switch off the machine and secure it to prevent unau-
thorized reactivation.
► Remove the plugs (motor tacho and incremental en-
coder) from the sockets on the intermediate distribu-
tor.
► Loosen the four M3x5 hexagon socket-head screws
which have been fixed with locking varnish (1).
► First loosen the upper M2.5x12 hexagon socket-head
screw (3) of the motor clamp fitting 2 (4), then the low-
er one.
► Loosen the two M3x14 hexagon socket-head screws
(6) on the motor clamp fitting (5).
► Carefully remove the Z axis drive (2) together with the
cables.
► Insert the Z axis drive (2).
► Make sure that the teeth of the toothed belt (7) en-
gage in the teeth of the motor pinion (1).
► Use the four M3x5 hexagon socket-head screws to fit
the Z axis drive.
► Tension the Z axis toothed belt by moving the Z axis
drive unit upwards and fix the motor with at least one
screw.
► Check the toothed belt tension with the belt tension
measuring device.

2. Z axis toothed belt
3. 2 x deflection wheel / DLM3
4. Tension jack (Z axis clamping device)
► Switch off the machine and secure it to prevent unau-
thorized reactivation.
► Loosen the two screws fastening the tension jack (3).

Installation
► Loosen the two M2.5x12 hexagon socket-head
screws (3) on the motor clamp fitting (4).
► Loosen the two M3x14 hexagon socket-head screws
(6) on the motor clamp fitting (5).
► Slightly loosen the four M3x5 hexagon socket-head
screws (1).
► Remove the toothed belt (7).
► Place the new toothed belt over the pinion of the Z
axis drive and the deflection wheels.
NOTICE!
Make sure that the teeth of the toothed belts engage in
the teeth of the pinion and deflection pulleys.
► Fit the tension jack (4) with the two fastening screws,
to the toothed belt.
NOTICE!
Make sure that both ends (2) of the tension jack lie on the
teeth of the toothed belt (1) .
NOTICE!
New tension jack
A new tension jack (fitted from 10/2007) has a profile
which engages with the toothed belt and therefore en-
sures a more reliable clamping.
