CAUTION
To avoid blocking of the clutch, it is important to take care that during setting and also for re-
adjustment the shortest spring pack length is not fallen short of. After re-adjustment, the spring-
type straight pins must be re-inserted into the drilled passages of the hexagon nuts.
Grease with special grease (graset 116 or 147) only.

GKN Walterscheid GmbH sets all clutches exactly to the specified torque.
The spring pack is pre-set according to the specified torque. Pre-setting is done at the
factory by determining the spring resistance.
The
torque setting may only be adjusted
by a professional shop and after
consultation with the implement manufacturer. Torque adjustment based on the
setting applied at the factory requires even screwing-on or unscrewing of the nuts
(SW 32).
If the torque is re-adjusted several times, it is no longer possible to check the
setting correctly. In this case, the torque setting either has to be checked by
means of an appropriate measuring device or directly at GKN Walterscheid
GmbH.
If a re-adjustable spring pack is installed, remove the spring-type straight pins (Item a).
Determine the existing spring pack length based on the sketch. Then re-adjust
according to the following table.
