Description
WARNING
Should reel model 7342 be used to deliver
gasoline or aircraft fuel, the:
• delivery and connecting hose must contain a
grounding wire
• entire fuel delivery system must be properly
grounded
This prevents the build-up of static electricity.
Personal injury can occur due to fire and/or explo-
sion.
NOTE: The reel is grounded at the swivel
with a wave washer. See Figure 2.
High-capacity hose reel model 7342 is designed to:
• deliver fuel (such as diesel fuel, aircraft fuel, and
gasoline) and lubricating oils.
• mount to a lubrication truck or to a ceiling* or wall.
This reel mounts as a single unit or in banks of as
many as required. See Figure 4 for details.
NOTE: The Hose Guide Arms can attach to the
Base Assembly in five (5) different positions.
This model reel is spring-powered and self-retracting.
When the hose is extended, the reel can be latched on
either of two ratchet sections per revolution of the sheave.
A pull releases the latch from the ratchet and allows the
hose to retract onto the reel.
This model reel manages a maximum length of
delivery hose as indicated in Table 1.

Reel Mount
HINT: Should the reel mount to the ceiling
or a wall, it may be advantageous to lessen
its weight with the removal of the Power
Spring Assembly.
Follow the appropriate procedural steps
within the section entitled Overhaul.
1. Mount the reel assembly with the proper hardware.
CAUTION
Never connect rigid piping to the Swivel assembly.
Damage to components can occur.
2. Screw a connecting hose (with thread sealant) into the
Swivel Assembly.
3. Attach the connecting hose to the supply line.
IMPORTANT: Anchor the connecting hose
to a suitable surface to prevent the hose from
flexing at the Swivel Assembly.
The anchor should be in-line with the inlet of
the Swivel to minimize side loading. See Fig-
ure 4.
Setting Power Spring Tension
4. Make sure there is no tension on the Power Spring
Assembly.
IMPORTANT: Wear non--slip gloves when
handling the Sheave Assembly.
5. While facing the Ratchet, turn the Sheave Assembly
clockwise to set the tension suggested for the type and
length of delivery hose used.
•SeeTable 3 for details.
6. Allow the reel to latch.
Bench Test
While facing the Ratchet, turn the reel in a clockwise
direction and allow the Ratchet to latch the Pawl.
If the reel does not tension or latch properly, refer to
the Troubleshooting Chart.
Installation
WARNING
Do not exceed the lowest pressure rating
of any component in the system.
Never point a control valve at any portion of your
body or another person. Lubricant discharged at
high velocity can penetrate the skin and cause
severe injury. Should any fluid appear to puncture
the skin, get medical care immediately.
Ensure all components are in operable condition.
Replace any suspect parts prior to operation. Per-
sonal injury can occur.
Hold the delivery hose securely until the reel is
securely latched or fully retracted. Uncontrolled
retraction can result in personal injury.

Once the Sheave Assembly is secure:
8. Install the delivery hose through the guide assembly.
9. Connect the delivery hose to the Shaft and Riser
Assembly.
• Make sure the connection is secure.
HINT: Orient the hose to allow its natural
curve to match the Sheave.
This reduces torque load on the Power
Spring Assembly and eliminates the ten-
dency of the hose to stack on one side of the
Sheave.
Delivery Hose Attachment
7. Screw the delivery hose (with thread sealant) into
Bushing (7) [if used] as required.
WARNING
Precautions must be taken to ensure the
Sheave Assembly remains engaged with the
Ratchet. To prevent movement either:
• instruct an assistant to grip the Sheave
securely with non-slip gloved hands or
• install a clamp on the Sheave. See Figure 5.
Personal injury can occur.
Figure 4 Space Required for Banked Reels (with Bolt Pattern Dimensions)

SER 7342 High-Capacity Reel
Revision (10-13) 10 Alemite LLC
10. Install U-Bolt (10) onto the delivery hose and to the Sheave
Assembly.
11. Install Washers (9) and Wing Nuts (8) onto the U-Bolt.
• Tighten the Wing Nuts securely.
Accessories Attachment and Pressurization
12. Install the control valve onto the delivery hose.
13. Pressurize the system.
• Check for leaks.
14. Install and secure the hose stop to the delivery hose at the
desired position.
15. Make sure the reel is latched then:
• instruct the assistant to let go of the Sheave Assembly
or
• carefully remove the clamp from the Sheave Assembly
16. Pull the delivery hose to disengage the Ratchet.
17. Allow the delivery hose to slowly retract onto the Sheave
Assembly.
Checking Spring Tension
18. Check to ensure the tension on the power spring
is sufficient to properly hold the hose stop
against the hose guide.
Should the power spring tension require
adjustment:
Adjusting Spring Tension
CAUTION
Do not overwind the power spring. Too much
tension reduces the life of the spring.
When the hose is fully extended from the
reel, the power spring should be a minimum
of 1/2 turn from a fully wound condition.
19. Release all pressure within the system.
WARNING
Disconnect the air supply line to the
pump’s motor.
Into an appropriate container, operate the
control valve to discharge remaining
pressure within the system.
20. Remove the control valve and the hose stop
from the delivery hose.
21. Pull the free end of the delivery hose through
the guide.
22. Rotate the Sheave Assembly in the required
direction.
23. Install the control valve and the hose stop.
24. Pressurize the system.
25. Check to ensure the tension on the power spring
is sufficient to properly hold the hose stop
against the hose guide.
26. Repeat steps 19 - 25 until the proper tension is
achieved.
