1. Torque values for international metric thread joints
All bolted joints on this machine must be torqued in accordance with the values given in this table below
unless indicated otherwise (e.g. in Parts List or Installation Instruction, etc.)
On all Kverneland Geldrop machines 8.8 is both standard and minimum quality used. If not indicated
anyhow use this quality for determination of torque (in most cases the quality can be found on the head
of the respective bolt).
Note: 1) The listet values are applicable for dry or slightly oiled joints.
2) When a stiff grease is applied decrease the given value by 10%. Do not use plated
bolts/screws/nuts without grease.
3) In case lock nuts, lock screws or lock bolts are used the given value must be increased
by 10%.
4) * = Material quality in acc. with DIN ISO 898.
** = Value in brackets means inch-pounds (in-lb).
5) *** = Size of jaw of lock bolts and nuts with toothed flange are given (metric values only)
in brackets if different from standard.
