USTOM ARM INSTALLATION
28G-77G 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.

Fasten the arm bases to the arm bars. Tighten the
capscrews to the torque values indicated below with a
drive extension tool, Cascade part no. 6040284
(14 mm) or 6040285 (17 mm).
28G – 275 Nm (200 ft.-lbs.)
36G, 44G, 52G – 535 Nm (395 ft.-lbs.)
64G, 70G, 77G – 585 Nm (430 ft.-lbs.)
IMPORTANT: Be careful not to damage the arm bar.
Premature bearing failure will occur.
Drive extension tool dimensions are provided for you
to make the tool from an allen wrench. Do not use mild
steel hex stock.

Place the rod ends on the cylinder rods. Install the split
rings.

Install the anchor bar through the cylinder rod end
and fasten to the arm anchor. Tighten the anchor bar
capscrews to a torque of:
28G, 36G – 90 Nm (65 ft.-lbs.)
44G, 52G, 64G, 70G, 77G – 225 Nm (165 ft.-lbs.)
