Warning
The toothed belt must be placed correctly on the clamping plate. It must not
protrude and must make contact with four teeth.
Note
The tapped holes of the clamping bodies must be recut before the threaded
pins are screwed in. Residues from the old locking agent in the tapped holes
result in uneven and increased torques for the threaded pins, which means
they may not be correctly tightened.
• Insert the left-hand end of the toothed belt together with the clamping plate
into the clamping body.
• Align the toothed belt axially with the centre of the clamping body.
• Apply Loctite 243 to the threaded pin and screw it into the clamping body.
• Push the clamping plate against the stop (a) on the clamping body.
Note
The clamping plate must make contact with the stop as otherwise the
toothed belt pretension will diminish during operation.
• Tighten the threaded pin using the appropriate torque (see table).
Note
It is critical that the torques be observed. Excessive torques will bend the
clamping body.
