GB OPERATING INSTRUCTIONS FOR CYLINDER STB WITH
Reassembly of the Guide Carriage
1. Clean all the parts.
2. Grease the felts (9) with guide grease.
3. Lay the wipers (10 or 30 + 31) and felts (9) in the wiper covers.
The sealing lip of the wiper must be outwards (see drawing).
4. Back off the adjusting screws (24) in the guide carriage.
5. Lay in the support strip (6) on the same side as the adjusting
screws.
6. Place 2 slide profiles (11) per side in the guide carriage.
The edges of the slide profiles in which grooves are cut (to allow
grease from the grease nipples to get to the guide rail) must touch
each other.
7. Screw on the two wiper covers (8 or 28 + 29) loosely with the
screws (7).
Remounting the Reassembled Guide Carriage on the Guide Rail
1. Push the complete guide carriage assembly carefully onto the guide
rail with the side with the adjusting screws towards the piston.
2. If necessary move the felt wiper carefully into its correct position
with a screwdriver.
Adjustment of Play
1. Tighten the self-locking adjusting screws (24), individually from
the middle working outwards, with the specified torque. If non-self-
locking screws are used (24), use a locking medium (Loctite low-
strength is recommended) and tighten the screws from the middle
working outwards until the guide carriage can no longer be moved
by hand.
2. Tap the sides of the guide carriage (23) gently with a rubber hammer
until the slide profiles (11) have settled into position and then tighten
all the adjusting screws (24) again (see above).
3. Loosen all the adjusting screws (24) about 1/4 to 1/2 turn
individually from the middle working outwards. When correctly
adjusted the guide carriage should be easily movable by hand but
with no play.
4. Tighten the screws (7) in the wiper cover (8 or 28 + 29) with the
prescribed torque.

The grease nipples on both sides of the guide carriage (23) should
be filled with guide grease until a thin film of grease can be seen on
the guide rail when the guide carriage is moved by hand.
Final assembly
1. Position the guide carriage centrally over the cylinder piston and
secure the drive blocks (27) with the washers (26) and screws
(25).
Note: The drive blocks (27) must be fitted against the guide
carriage (23) or carrier (34) with no play !!! See the table for the
correct torque !!!
2. Push the saucer springs (18) and pressure plates (19) onto the
guide pin.
Note: See the diagram for the correct arrangement of the saucer
springs and pressure plates. Depending on the brake type the
numbers of saucer springs (18) and pressure plates (19) are different.
3. Lay the plate (22) on the
pressure plates (19).
4. Tighten the screws (21) with
their washers (20) gradually
and evenly until the plate (22)
lies completely flat on the
guide carriage (23).
5. Refit the end cap of the
cylinder, if applicable.
