Dirty or used clamping sets must be disassembled, cleaned and afterwards oiled with thin-bodied oil (e. g. Castrol 4 in 1 or Klüber Quitsch Ex) before the assembly. ! C AU T I O N ! When assembling the internal ring (part 2) and the external ring (part 1) please make sure that the slots are staggered. The forcing thread of the internal ring (part 2) must not be congruent with the slot of the external ring (part 1).

Geprüft: 16.08.06 Sha Ersetzt durch: 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). ! C AU T I O N ! Do not use oils and greases with molybdenum disulphide or high pressure additions as well as slide grease pastes. • Lightly unscrew the clamping screws. To facilitate the assembly fasten the internal and external ring via the pull-off threads by means of two clamping screws (see drawing 2). Insert the clamping set KTR 250 between shaft and hub. picture 2: fixing of the clamping set KTR 250 • Slightly tighten the clamping screws manually and align the clamping set with hub part. • Regarding KTR 250 please make sure that the axial supporting ring (component 3) fits closely and evenly. • 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.
