DANGER !
With assembly and disassembly of the clamping set it has to be made sure that the
entire drive train is protected against unintentional engagement. You can be
seriously hurt by rotating parts. Please make absolutely sure to read through and
observe the following safety instructions.
•All operations on and with the clamping set have to be performed taking into account "safety first".
•Please make sure to disengage the power pack before you perform your work at the clamping set.
•Protect the power pack against unintentional engagement, e. g. by providing hints at the place of
engagement or removing the fuse for current supply.
•Do not touch the operation area of the machine as long as it is in operation.
•Please protect the rotating drive parts against unintentional touch. Please provide for the necessary
protection devices and caps.

CAUTION !
Check the clamping set before the assembly, so that the slots of component 1, 2
and 3 are flush with each other.
FATTENTION !
Plan a free space between the pressure ring in the back and the hub/shaft for a
later disassembly.

Assembly
•Check the position of shaft and hub regarding the stipulated tolerance (h8/H8).
•Clean the hub bore and the shaft and afterwards oil them with thin-bodied oil (e. g. Castrol 4 in 1 or
Klüber Quitsch Ex).
!
CAUTION !
Do not use oils and greases with molybdenum disulphide or high pressure
additions as well as slide grease pastes.
•Detach the screws slightly. To make the assembly easier, fix the pressure rings in the front and in
the back via the respective forcing thread by 2 clamping screws (see picture 3 and 4). Insert
clamping set KTR 400 between shaft and hub.

•Remove the clamping screws used for the fixing and screw them into the threads of the back
pressure ring.
•Slightly tighten the clamping screws manually and align the clamping set with hub part.
•At KTR 400 please make sure that the pressure rings are parallel to each other and in an angle of
90° to the shaft/hub.
•Tighten the clamping screws evenly and crosswise. Increase the tightening torque step by step.
This procedure must be repeated until the tightening torque indicated in table 1 is reached with all
clamping screws.

FATTENTION !
During the assembly there can be a slight axial displacement of the hub opposite to
the shaft.

Disassembly
STOP
DANGER !
Loosened or falling drive parts can cause injuries to persons or damages to the
machines.
Safe the drive parts before the disassembly.
•Loose all clamping screws evenly one after the other and unscrew them.
•Screw the clamping screws into the forcing threads of the front pressure ring (component 1)
(see picture 5).
•Tighten the clamping screws evenly and crosswise. Increase the impression torque step by step
until the front pressure ring (component 1) and the external ring (component 3) are separated.
•Screw the clamping screws into the forcing threads of the external ring (component 3)
(see picture 6).
•Tighten the clamping screws evenly and crosswise. Increase the impression torque step by step
until the back pressure ring (component 2) and the external ring (component 3) are separated.
•Remove the unscrewed clamping set between shaft and hub.
