10.8 Bolted connections
Bolts and nuts that are mounted on the Unimog and the Uni-
mog frame may only be replaced by bolts with the same di-
ameter, the same grade and the same thread pitch.
Observe prescribed tightening torque.
Following items should be considered by using bolt connec-
tions:
•
Use fit bolts, headless bolts or flange head bolts (grade
8 and if available SAE fine thread) and flange nuts or
flange lock nuts for bolt connections on the Unimog
(see Figure 10.9).
•
Use existing drillings and drill new holes only if it is es-
sential.
•
Adapt the number of bolts to the load, if necessary re-
move paint down to the primer to minimize setting
symptoms.
•
Use sufficiently strong washers for clamping sleeves
and anti-fatigue sleeves.
Examples for bolted connections:
In case of transferring lateral forces with positive locking bolted
connections a clamping sleeve should be used (see Figure
10.7). For minimizing the loss of preload force caused by sub-
sidence sufficiently long bolts or anti-fatigue sleeves should be
used (see Figure 10.8).
