5.9 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).
* Material quality in acc. with DIN ISO 898.
** Value in brackets means inch-pounds (in-lb).
*** Size of jaw of lock bolts and nuts with toothed flange are given (metric values only) in brackets if different
from standard.
-
The listet values are applicable for dry or slightly oiled joints.
- When a stiff grease is applied decrease the given value by 10%. Do not use plated bolts/screws/nuts without
grease.
- In case lock nuts, lock screws or lock bolts are used the given value must be increased by 10%.
-
Torque value of wheel nuts M18x1,5 shall be 270 Nm (200 ft-lb)!
