2 Hose Length Calculation
Length Calculations
H =Total lift height
D = Distance from centerline of reel to hose end with carriage
fully lowered.
K =CONSTANT = 18 inches (460mm) for No. 4
1. When H is equal to, or greater than 2 x D the correct hose
length is:
H-D+K
2. When H is less than 2 x D the correct hose length is:
D+K
Example inches
H = 286”
D = 96”
K = 28”
286”-96”= 190”+28”=218”correct hose length.
In this case, use hose 673395.
Example mm
H = 7265mm
D = 2440mm
K = 710mm
7265-2440 = 4825+710 = 5535 correct hose length.
In this case, use hose 673395.
= 28 inches (710mm) for No. 6

3 Periodic Maintenance
500 Hour Maintenance
After each 500 hours of lift truck operation, perform the
following procedures.
Ž Retorque the mounting capscrews. Use the torque
specifications shown in Section 5.
Ž Retighten all hydraulic hose fittings.
Ž Check hoses for cracks, peeling or leaking. Replace as
required.

4.1 Troubleshooting Guide
PROBLEM
Excessive wear on hose.
Hose jumps off reel
during operation.
Hose binds during operation.
Hose reel leaks at hub.
PROBLEM CAUSE SOLUTION
Hose reel and hose terminal are
not in proper alignment.
Hose reel flanges damaged.
Hose reel not aligned with hose
terminal.
Incorrect prewind of spring.
Hose reel spring is broken.
Flanges are bent.
Worn or cut seals in the rotating hub.
Loose or damaged fittings.
Scored seal areas.
Align the hose terminal and hose reel properly.
They must be on the same center line and
mounted squarely to each other.
Repair or replace damaged parts.
Align hose terminal with hose reel.
Prewind spring.
Replace the spring.
Straighten or replace flanges. See Section 5.2.
Replace all seals. When a hose reel requires
immediate replacement of any one of the
O-rings or back-up rings, it is important that all
the rings be replaced. If all the rings are not
replaced at the same time, the reel will only
have to be disassembled again in a short
period of time to replace the older rings. The
seal kit offered by Cascade includes all of the
O-rings and back-up rings necessary to
rebuild one hose reel. Order Seal Kit
No. 672563.
Tighten or replace damaged fittings.
Replace the damaged shaft or use
an emery cloth (320 grit) to remove the
nicks from the shaft or hub.

5/1 Disconnecting the Reel
NOTE: It is not necessary to remove the reel assembly from
the truck. All service procedures may be done in place; but
for purposes of this manual, they will be done on the work
bench.
1 Remove the twinline hoses from the hose terminal.
WARNING: Hold hoses firmly while
disconnecting them from the carriage.
Allow the reel spring to unwind slowly
while maintaining tension on the loose
hose ends. Note the number of prewinds
while unwinding the hose reel. For
reassembly, tighten the hose terminal
clamp capscrews to 15-20 ft.-lbs.
(20-27 N.m).

the reel to the mounting bracket. Remove the reel from
the mast. For reassembly, tighten the capscrews to
30-35 ft.-lbs. (40-47 N.m).
Determine whether the reel is a right or left hand model

(viewed from the outer flange side of the reel). This
must be noted for future reference. If the reel is lefthanded, an ‘L” will show on the hub casting. If the reel is
right-handed, an “R” will show on the hub casting.

5.2 Reel Disassembly
1 Clamp the reel mounting block in a vice.
2 Remove the twinline hose.
3 Remove the capscrews fastening the flanges and hub to
the spring/shaft assembly. For reassembly, tighten the
capscrews to 10-14 ft.-lbs. (13-19 N.m).
4 Remove the capscrew, end cap and O-ring from the
shaft end. For reassembly, tighten the capscrews to
10-14 ft.-lbs. (13-19 N.m).
5 Grasping both flanges and hub as an assembly, slowly
rotate as you pull them off the shaft.
6 Separate the hub from the flanges.

8 Rotate the spring assembly to disengage the declutch-
ing pin and slide the O-rings and spring assembly off
the shaft, being careful not to damage the shaft O.D.

5.2 Reel Disassembly (Continued)
8 Remove the three O-rings and four back-up rings from
the hub bore. Remove O-rings first by prying them out
with a hook-type dental tool or a small flat screw driver.
(Use Cascade O-ring Tool Part No. 674424.) Use the
same tool to remove teflon rings next.
NOTE: Do not scratch or damage groove surfaces.
9 Clean the hub and shaft with a non-corrosive solvent.
Inspect the following areas:
l The sealing surface on the shaft is nickel plated. If
minor surface imperfections are noted, use emery
cloth (320 Grit) to lightly smooth up. Sand radially
around the shaft. If sharp edges or grooves are found,
shaft replacement is necessary.
l Hub grooves must be free of sharp nicks or projec-
tions to prevent cutting of the outside diameter of the
O-ring during installation.
If the O-ring seal nearest the spring assembly was
damaged and allowed hydraulic oil to leak into the
spring can, drain the spring can before reassembly. If
excessive oil is left in the spring assembly, it will seep
out after reassembly and appear as though there is a
serious oil leak.
10 Apply a liberal amount of petroleum jelly or hydraulic oil
(STP) to the shaft, seals and the interior of the hub before
reassembling.
11 Install the four back-up rings into their respective hub
grooves. Next, install three O-ring seals.

12 Reverse Steps 1 through 7 for reassembly, being careful
to rotate the hub slowly as you push it onto the shaft. This
will prevent damage to the seals and make reassembly
easier. Also be sure O-ring dust seals (3) are in their
correct positions.

5.3 Hose Replacement
1 Disconnect the twinline hoses from the hose terminal.
WARNING: Hold hoses firmly while
disconnecting them from the carriage.
Allow the reel spring to unwind slowly
while maintaining tension on the loose
al._-
2 Cover the number of prewinds while unwinding the hose
3 Disconnect the hoses from the reel hub. It is not neces-
sary to remove the outer flange.
4 Remove the hoses from the reel.
5 Connect the new hoses to the reel hub fitting.
NOTE: Thermoplastic twinline hose has a natural bend
or set. Wind the hose with the bend of the hose matching
the flange bend. Do not twist hose when tightening
fittings.
6 Wind the new hose assembly completely onto the reel in
the direction indicated (viewed from the outer flange
side):
Right Hand Reel: Wind hoses clockwise.
Left Hand Reel: Wind hoses counterclockwise.
A Right or Left hand reel is determined as viewed from
the flange side of the reel. An “R” or “L’ letter on the hub
casting will identify the reel.
7 Remove the restraint from old hoses by twisting off.
Install new hoses by twisting into the restraint.
8 Prewind the reel spring by grasping the end of the hose
and turning the reel the specified number of complete
turns in the direction indicated (viewed from the outer
flange side).
Right Hand Reel: Wind reel clockwise.
Left Hand Reel: Wind reel counterclockwise.
Normal prewinds = No. 4-11 - 5 turns
If more tension is required, the reel can be prewound
additional turns. The maximum total turn capacity of the
reel is:
Total Turns = Prewind Turns + Working Turns
Caution: Exceeding the total turn capacity of the reel
will damage the reel spring.
9 Reconnect the hoses to the hose terminal. Tighten the
hose terminal capscrews to 15-20 ft.-lbs. (20-27 N.m).
10 Cycle mast carriage slowly to ensure adequate hose
install clamp with
detent between first
and second segments.

Reversing the Reel
Assembly
The reel assembly can be converted from a right hand reel
to a left hand reel or from left to right as follows:
1 Disconnect the reel assembly from the truck as de-
scribed in Section 5.1.
2 Disassemble the reel to gain access to the spring as-
sembly as described in Section 5.2, steps 1 through 7
3 Remove four nuts and bolts that retain the spring can
cover.

WARNING: Once the spring cover is
removed, the spring itself should never be

4 Turn the spring can assembly, making sure that can and
cover stay together.
5 Lift off the spring can, leaving the cover and spring on
the work bench. Flip over spring can.

allowed to be turned to any position other
than flat without manually covering the
spring. The spring is banded but can
come out by gravity or bouncing.
WARNING: Do not remove spring from
inner can.

6 To reverse the spring direction, use the spring cover and
slide the spring into the can. Align the can notch with the
spring washer, When complete, the spring winding will
be exposed for a right hand reel and covered for a left
hand application.
7 Reverse the spring retainer pin by removing the snap
ring and rotating the retainer pin 180°. Replace the snap
ring.
8 For reassembly, reverse the above procedures except
as follows:
*Tighten the spring can cover nuts to a torque of 30-40
in.-lbs. (3-4 N.m).

tion shown in Section 5.1 Step 4.
