Replacing the tensioning keys
Installing the tensioning key, item 1 (synchronizing disk,
short)
► Place the tensioning key on the "short synchronizing
disk" (9).
► Fasten the tensioning key with the M4 x 5 hexagon
socket-head screw (8).
Installing the tensioning key, item 2 (synchronizing disk,
long)
► Use the Benzing U clip to fit the spacer bolt (7) onto
the new tensioning key.
► Place the tensioning key on the "long synchronizing
disk" (10).
► Use the size 8 Allen key to turn the synchronizing disk
slightly until the hexagon socket-head screw (3) can
be screwed in.
► Pretension the toothed belt by turning the hexagon
socket-head screw clockwise.
Replacing the tensioning keys
► Push the head mount towards the X-axis motor as far
as the stop on the elastomeric spring.
► Turn the hexagon socket-head screw to set the belt
tension to 53 Hz + 1/3 Hz.
CAUTION! Do not overstretch the toothed belt
when adjusting the belt tension.
► Secure the hexagon socket-head screw (3) with the
locknut (11).

⇨ Loosen the locknut (11),
⇨ Turn the hexagon socket-head screw (1) counterclockwise.
► Remove the M4 x 35 hexagon socket-head screw (1).
► Pull the tensioning key (2) off the synchronizing disk (3).
► Pull the toothed belt (9) out through the opening in the tension jack (4).
► Unthread the toothed belt from the deflection unit (8).
► Loosen the two M3 x 8 hexagon socket-head screws (6) and remove the Y-brake "outside" (5).
► Loosen the two M6 x 10 hexagon socket-head screws (7) and remove the deflection unit ’X’ (8).
► Remove the elastomeric spring (10) from the deflection unit.
