Product Detail

Robotically welded base –greatly reduces
imperfections in weld. Weld settings such as
temperature, speed and size are repeatable
with less instance of human error.
Mounting holes – Four 1/2” holes in base
plate.
Structural forms –incorporated into the
design to give added strength throughout the
reel.
Base and upright are stamped from 11 gauge
sheet steel.
Mounting hole for latch pawl assembly
secured with a nut.
Mounting hole for shoulder screw that
anchors latch spring.

Base
Threaded studs are pressed into the upright
sheet metal. It is these four press studs to
which the guide arm is eventually fastened.
Steel hub is welded into upright and
incorporates a set screw that engages a flat
machined surface on the main shaft to
prevent the main shaft from rotating while
reel is in use.
Main shaft is machined from solid stock. It is
zinc plated carbon steel on standard OLP,
OMP and OHP models. On models with a
stainless steel flow path, a 316 grade shaft is
used. Output thread on shaft is either 1/4”,
3/8”, 1/2” or 3/4” NPTF.

Base
Two snap rings inserted in machined grooves
on main shaft on either side of the weld in
hub hold shaft in place.
Machined flat engages aluminum arbor key
that in turn, keeps the spring arbor from
rotating, thus building spring tension.

Cast aluminum latch pawl
Stainless steel tension spring
attaches to latch pawl and
shoulder screw.
Customers requiring a reel that is constantly in tension can remove these parts
from a standard latching reel or order it from the factory as such by adding the
suffix “CT” to any spring driven hose reel model number.
Latch spring is a wear item. Every
flick of the latch pawl causes stress
on the spring. Reelcraft does
extensive cycle testing on its latch
spring designs.

Spring Case
Spring case stamped from 18 gauge steel and formed for
added support.
Four rivets affix the aluminum ratchet to the spring case.
Bronze bushing is impregnated with oil for smooth operation
and requires no maintenance.
Spring case stud is mounted through this hole in the
spring case and serves as the anchor point for the
drive spring.
Cast aluminum ratchet has latching positions ever
180º. Latching parts are designed to be wider than
competitors for improved wear.
Stamped spring case and ratchet are sold as an
assembly.

Spring Case
Spring case stud is assembled with a nut on
the opposite side of spring case.
Spring case is assembled onto shaft and
arbor and arbor key are fitted into the correct
position.
The partially assembled reel is now ready to
receive one of six standard drive springs.

Drive Spring
Drive springs are wound in house from scaleless blue
spring steel and conditioned to remove imperfections.
Even the slightest flaw can lead to the premature failure
of the hose reel. Springs are banded for safety.
Before the spring is wound, the
material is heated and the end is
Formed in a stamping die. This is
where the spring will engage the
arbor. With drive spring installed, it
is time to attach the sheave
assembly.
Spring is attached to spring case stud. Spring case,
sheave and disc rotate around the main shaft and arbor,
which are stationary. As hose is de-spooled the spring is
concentrically expanding outwards toward the spring
pan, storing energy that will eventually be used up in
the retraction of the hose.

Drive Spring
Customer’s supplying their own hose should follow our online technical bulletin for
required number of wraps –OR –looking at the swivel side, they can grab the sheave
assembly and carefully wind it counter-clockwise until the spring bottoms out against the
spring pan. The reel should not turn any further. Once the spring is bottomed out, it is at
maximum tension. Carefully, rotating the spool clockwise two full revolutions and latch the
reel. Hose can now be installed, by threading it carefully onto the gooseneck. Atug of the
hose should release the latch and the hose can be guided onto the reel.
Proper spring tension is predicate on the length of hose being installed on the reel.

Sheave Assembly
The sheave assembly consists of three separate components:
disc, sheave and arbor. These parts are not sold independently,
because it is unlikely an end-user could replicate our
manufacturing process with common tools.
Disc is stamped from 16 gauge sheet steel and incorporates
press studs that correspond to those on the spring case. The
whole assembly gets bolted on to the spring case and fastened
with nuts.
Sheave is permanently swaged to disc and then the entire
assembly is run through the powder coat line. The sheave arrives
at the pictured state through multiple stamping operations.
Reinforcing ribs are added, holes cut and a transition is added so
that the hose moves seamlessly onto the spool.
Nylon arbor is then riveted in place.

Sheave Assembly
The entire sheave assembly is then
assembled onto the shaft, mating to the
spring case assembly. Together they
encapsulate the drive spring.
Gasket is used to prevent dirt, dust and
debris form entering the spring case. It is
not intended to make the reel waterproof
and pressure washing the reel can damage
this gasket.
Light lithium based assembly grease is
added to prevent any binding of the spring
inside the spring case.
Six press studs affix sheave to spring case
assembly with nuts.

Guide Arm
Stamped form 11 gauge steel, the guide roller benefits
from engineered forms throughout.
Raw stampings are run through the powder coat line.
UHMW guide roller assembly is riveted in place.
Customers looking to replace a guide roller will need to
by the entire guide arm assembly.
Four nuts attach the guide arm to corresponding press
studs on the base. Standard guide arm position from
the factory is top wind (TW). Other positions are
available as standard, but must be specified at time of
order.

FAQs

My Reel Won’t Retract at All!?!
Latch out
•Reels come from the factory in
top wind position.
•If a customer moves the guide
arm position on the reel before
installation, they will also need to
move the U-bolt to the
corresponding position on the
spool to prevent “latch out” at full
extension.
Note: Refer to service manual for
further instruction
Freight damage
•7000 Series reels leave the
factory in a double wall
corrugated cardboard box. They
are enclosed in a bag and have
foam inserts.
•It is always wise to inspect the
packaging before receipt of a reel.
If the packaging is damaged, pull
un-box and ensure that the reel
operates smoothly and there are
no dents, scratches, dings in the
sheet metal before signing for
delivery.

My Reel Will Not Retract at All!?!
Seizure
•In particularly dirty or grimy work environments, debris can lodge in
the bushing on the ratchet and fuse the ratchet to the main shaft.

© Reelcraft Industries
My Reel Won’t Latch!?!
Damaged, disassembled
or missing latch spring.
•The latch spring holds the pawl
tight to the ratchet.
•Over the life of a reel, latch springs
may stretch while they wear and
become ineffective.
•The hose has snapped back and
the resulting force un-hooks the
latch spring or breaks it entirely.
•Investigate and replace latch
spring.
Constant Tension
• Reelcraft offers most all of it’s
latching reels in a constant
tension version as well. This will
be designated in the part number
with a “-CT” suffix.
7650 OLP (standard)
7650 OLP-CT (constant tension)

Add tension
•Coil springs with time will loose
some of their tension.
Customer supplied hose
• Customer’s hose may not meet
our minimum bend radius or
recommended O.D.
Reel mounted in excess of
15’ overhead
•This type of installation
necessitates that the bumper be
set such that 15’ or more of hose
is hanging off the reel at all times.
In turn, tension is increased on
the drive spring, causing it to wear
prematurely or in extreme cases
fail entirely.
•Always consult engineering in
this type of application.
