USTOM ARM INSTALLATION
120G & 140G Clamps
Clamps without arms are supplied with two arm bases.
Special forks can be welded directly to them or they can
be used as a base to fabricate custom built arms.
WARNING: Cascade requires that a
qualified or certified welder experienced
in this type of fabrication be used for best
quality.
CAUTION: Weld fabricated arms to the arm bases only.
Do not weld or bolt special built arms or forks directly to
the arm bars.
The arm base material is AISI C-1020 HR with the following
specifications:
• TENSILE STRENGTH – 420 mPa min. (61,000 PSI)
• YIELD STRENGTH – 300 mPa min. (43,000 PSI)
• CARBON CONTENT – 23% max.
CAUTION: The surface flatness of the arm base must
remain within .25 mm (.010 in.) in capscrew area and arm
must slide manually.
1
Fasten the arm bases to the arm bars. Tighten the
capscrews to the torque values indicated below with
a drive extension tool 676218 (19 mm) to tighten
capscrews to a torque of 924 Nm (682 ft.-lbs.)
IMPORTANT: Be careful not to damage the arm bar.
Premature bearing failure will occur.
Drive extension dimensions are provided to make the
tool from the allen wrench. Do not use mild steel hex
stock.
2
Lubricate the cylinder rod threads, nut threads and
spherical portion of the nut with wheel bearing grease.
3
Install the hex washer on the rod end with the beveled
side facing the lug.
4
Engage the rod end into the lug.
5
Tighten the rod end nut to a torque of 340 Nm
(250 ft.-lbs.).
Prevent rod turning by using wrench on hex washer.
NOTE: The rod nut is being tightened against the hex
washer. The nut will not be tight against the arm base
lug. This looseness allows for cylinder alignment during
clamping.
6
Install the locking cap and cotter pin.
7
Lubricate the bearing portion of the arm bars with a thin
film of chassis grease, if required.
