TOWER TIE BOLT APPLICATIONS
Certain pulling and/or pushing situations necessitate
use of tower tie bolts in place of tower pins. Tower tie
bolts must be inserted through one of the outer tie
down holes on mainframe (or movable crossmembers)
and be threaded into one of the pinning holes on tower
gusset. Tower tie bolts must be tightened to between
120-150 foot pounds (160 -200 Nm) of torque.
Tower tie bolts must be installed when the following
situations exist:
1. Tower does not lift up firmly against underside of
mainframe when making a pull, for example: when
pulling upward at 45 degree angle or less. (See
Figure 14.)
NOTE: Tower will not lift in this situation and will
be forced down if tower tie bolt is not
installed.
2. Auxiliary ram is used to push from tower to vehicle.
(See Figure 15.) Tower will be forced down in this
situation unless tower tie bolt is installed.
CAUTION: DO NOT attempt this setup with-
out reading Auxiliary Ram Owners
Manual.
3. Pull from side of tower exceeds 45 degree angle from
tower base. (See Figure 16.) This situation does not
necessarily force tower up or down, but instead
causes tower pedestal rings to twist.
NOTE: The higher collar is on tower, the more
severe the twisting action.
