Tightening
4
Lubricate nuts and threaded support.
5
Tighten connecting rod nuts to 40 - 50 Nm initial torque and 90-100° angle of rotation torque.
Attention!
Tighten connecting rod bolts knocked in with a hammer for the first time at 60 - 70 Nm initial torque and 90-100° angle of rotation torque.
This specification must be strictly observed since otherwise the connecting rod nuts may become loose.
NOTE: If no angle of rotation tool is available, the connecting rod nuts can also be tightened by means of a normal socket wrench with tommy
bar in one step by an angle of 90-100°. This angle should be estimated as accurately as possible. To eliminate angle of rotation errors, do not
use torque wrench for tightening according to angles of rotation.
