➀Cascade D-Series Clamps are compatible with SAE 10W
petroleum base hydraulic fluid meeting Mil. Spec. MIL-0-5606 or
MIL-0-2104B. Use of synthetic or aqueous base hydraulic fluid
is not recommended. If fire resistant hydraulic fluid is required,
special seals must be used. Contact Cascade.
➁Flow less than recommended will result in unequal arm
movement.
➂ Flow greater than maximum can result in excessive heating,
reduced system performance and short hydraulic system life.

2.4 Custom Arm
Installation
Attachments 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 – 61,000 PSI (420 mPa) Minimum
• YIELD STRENGTH – 43,000 PSI (300 mPa) Minimum
• CARBON CONTENT – 23% Maximum
CAUTION: The surface flatness of the arm base must
remain within 0.10 in. (.25 mm) 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, 668020 (25D), 667699
(35D,40D,50D) or 676218 (70D,80D, 100D) to tighten
capscrews to the following torque values:
25D – 190–220 ft.-lbs. (257–298 Nm)
35D, 40D, 50D – 280–320 ft.-lbs. (380-434 Nm)
70D, 80D, 100D – 680–720 ft.-lbs. (922-976 Nm)
IMPORTANT: Be careful not to damage the arm bar.
Premature bearing failure will occur.
Short adapters care commercially available:
Williams .50 in. drive to .625 in. hex (25D) and .50
in. drive to .625 in. hex (35D, 40D, 50D) and .75 in.
drive to .75 in. hex (70D, 80D, 100D). Drive extension
dimensions are provided to make the tool from the allen
wrench. Do no 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 the following torque values:
25D, 30D, 40D, 50D – 150–175 ft.-lbs. (203-–237 Nm)
70D, 80D, 100D – 225–250 ft.-lbs. (305–340 Nm)
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 permitted by your application.

2.5 Prior to Operation
1 Check the cylinder anchor nuts for properly installed
locking caps and cotter pins.
2 Check for external leaks at the fittings and rod ends.
25D, 35D, 40D and 50D Clamps – The clamp utilizes a
regenerative hydraulic circuit in the arm opening mode.
The arms will open at a faster speed than when closing.
This is normal. If required, the regenerative function
can be eliminated. Refer to Section 5.6-5.
3 Check for equal arm travel. If arm travel is unequal, the
restrictor cartridges should be adjusted as follows:
A Loosen the jam nuts on the restrictor cartridges.
Screw in the plungers until they bottom. Screw each
plunger out three full turns.
B Activate the arms to the fully open position
C Activate the arms to close until one arm bottoms
out. Measure the amount of stroke remaining in the
opposite arm.
D If unequal closing movement exceeds 2 in. (50 mm),
screw the plunger in 1/2 turn on the cylinder that
bottoms first.
E Repeat step Athrough Duntil unequal closing
movement is less than 2 in. (50 mm).
4 Before picking up a load, cycle the clamp function
through several full cycles. Check for operation in
accordance with ITA (ISO) standards.
WARNING: Make sure all personnel are
clear of the clamp during testing.

ERIODIC MAINTENANCE
P
3.1 100-Hour Maintenance
Every time the lift truck is serviced or every 100 hours
of truck operation, whichever comes first, complete the
following maintenance procedure:
• Inspect the cylinder anchor joint for lubrication and
correct hold.
NOTE: Anchor joint operates with a loose clearance.
Lubricate with wheel bearing grease.
• Arm bearing life can be extended by a light application
of chassis grease, if permitted by your application.
• Tighten arm capscrews to the following torque value:
25D – 190–220 ft.-lbs. (257–298 Nm)
35D, 40D, 50D – 280–320 ft.-lbs. (280–434 Nm)
70D, 80D, 100D – 680–720 ft.-lbs. (922–976 Nm)
3.2 500-Hour Maintenance
After each 500 hours of truck operation, in addition to the
100-hour maintenance, perform the following procedures:
• Check the lower mounting hook engagement clearance
with the truck carriage bar:
Quick-Change Hooks – 3/32 in. (2.5 mm) minimum
3/16 in. (5.0 mm) maximum
Bolt-On Hooks – Tight against lower carriage bar
If adjustment is necessary, refer to Installation Step 6.
Tighten the lower hook capscrews as follows:
Class II/III Mounting – 110 ft.-lbs. (150 Nm)
Class IV Mounting – 190 ft.-lbs. (260 Nm)
• 70D, 80D, 100D Clamps – Tighten the upper hook
capscrews to 210 ft.-lbs. (285 Nm).
• Check clamp force. Cascade Clamp Force Indicators
35G-DFI-8RF and 35G-CFI-8RF are available for this test.
3.3 1000-Hour Maintenance
After each 1000 hours of truck operation, in addition to
the 100 and 500-hour maintenance, perform the following
procedures:
• Inspect the arm bearings for wear. If any bearing is
worn to less than .040 in. (1 mm) thickness, replace all
bearings. Refer to Service Section 5.2-5.
3.4 2000-Hour Maintenance
After each 2000 hours of truck operation, in addition to
the 100, 500 and 1000-hour maintenance, perform the
following procedures:
• Inspect the arm bearings for wear. If any bearing is
worn to less than .040 in. (1 mm) thickness, replace all
bearings. Refer to Service Section 5.2-5.
• Tighten the frame mounting plate capscrews to the
following torque value:
25D, 35D – 60 ft.-lbs. (85 Nm)
40D, 50D – 110 ft.-lbs. (150 Nm)
70D, 80D, 100D – 190 ft.-lbs. (260 Nm)
