5.18 SCREW CONNECTIONS INSPECTION

TIGHTENING TORQUES FOR SCREW

CONNECTIONS

During maintenance and repair work, apply
appropriate tightening torques to screw
connections, unless other tightening pa-
rameters are given. Recommended tight-
ening torques for the most commonly used
bolted connections are shown in the Table
(5.4). The given values apply to non-lubri-
cated steel bolts
The hydraulic hoses should be tightened
with a torque of 50 -70Nm.
Check the tightness using a torque wrench

.

During daily inspection of the trailer pay
attention to loose connections and tighten
the connector if necessary. Replace lost
items with new ones.
