➀ Cascade 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.

➁ Flow 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 A through D until 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

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)
