IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS!
This manual contains important instructions that should be followed during installation and maintenance of
the Pressure Fuelling Nozzle (nozzle). The following are general safety precautions that are not related to
specific procedures and therefore do not appear elsewhere in this publication. These are recommended
precautions that personnel must understand and apply during maintenance.
The nozzle is a mechanical device and can be dangerous if incorrectly operated or maintained.
Safety Alert Symbols
Safety alert symbols are used in this manual to identify potential or immediate personal injury hazards. The
safety alert symbol words are explained below:
- indicates an imminently hazardous situation which, if not
avoided, will result in injury or serious injury.
- indicates a potentially hazardous situation which, if not avoided,
could result in injury or serious injury.
- indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury.
- used without the safety alert symbol indicates a potentially
hazardous situation which, if not avoided, may result in
property damage.
WEAR PROTECTIVE CLOTHING
Wear protective clothing (gloves, apron, etc.) approved for the materials and tools being used.
USE APPROVED SAFETY EQUIPMENT
Use only approved equipment and make sure firefighting equipment is readily available.

GIVE CLEANERS SPECIAL CARE
When cleaners are being used read and follow the material safety data sheet (MSDS) instructions for
correct handling.
Equipment Safety Information
The following safety information briefly discusses hazards peculiar to the equipment, which are likely to be
encountered during maintenance activity.
GENERAL OPERATING LOCATION PRECAUTIONS
Use only authorized replacement parts or hardware.
Obey Lock-Out/Tag-Out procedures when working on the nozzle and make sure that personnel
protection equipment such as electrical grounds are installed.
Avoid hazardous voltage situations that can result from unsafe conditions such as, but not limited, to
the following:
o Incorrect grounding
o Handling electrical leads or devices with wet hands or on wet ground.
o Damaged electrical wire insulation.
o Incorrect connection of the power terminals.
o Short circuits to ground.
OPERATION AND MAINTENANCE OF FUEL SYSTEMS
BEFORE TURNING THE OPERATING LEVER; MAKE SURE ALL 3 LUGS
OF AIRCRAFT FUELING ADAPTER ARE PROPERLY ENGAGED IN THE
F145J NOZZLE. REFER TO SAFETY BULLETIN 7872 FOR MORE DETAILS.
Protect all fuel lines from damage or puncture. Do not operate the nozzle if a fuel leak is detected.
Do not use flammable solvents for cleaning parts.
Check for tools, rags, or loose parts left in the area before resuming operation.
Do not attempt to remove the nozzle from the system without first isolating it from the line pressure and
venting all of the trapped internal pressure.

DESCRIPTION AND OPERATION
1. Description
The Pressure Fuelling Nozzle (nozzle) (see Figure 1) provides the means of controlling the flow of fuel
in pressure fuelling operations. The nozzle inlet port couples to a fuelling hose. The outlet port attaches
to the inlet adapter of the system being fueled. The nozzle provides a leak proof connection between
the system being fueled and the fuel supply.
2. Operation
A. Uncoupled
When the nozzle is not coupled to a mating fuel system inlet adapter, its poppet valve is closed, so
that there is no flow or leakage of fuel from the outlet port. The flow control handle that operates
the poppet valve remains locked in the CLOSED position until the nozzle is coupled to the mating
fuel system inlet adapter.
B. Coupling and Opening
When the nozzle is coupled to the mating fuel system inlet adapter, the nose seal of the nozzle is
compressed against the sealing surface of the inlet adapter to form a fluid-tight connection. When
the nozzle is fully engaged and locked to the bayonet flange of the inlet adapter, the flow control
handle is unlocked. Rotation of the flow control handle to the OPEN position opens the poppet
valve, providing a flow passage into the system being fueled. As the system is being fueled, fuel
pressure acts on the floating nose seal of the nozzle to increase the sealing force.
C. Closing and Uncoupling
Rotation of the flow control handle to the CLOSED position closes the poppet valve and the flow
passage into the system being fueled. When the nozzle is unlocked and disengaged from the
bayonet flange of the inlet adapter, the flow control handle is locked in the CLOSED position.
D. Adapters
Suitable attachment adapters such as swivels and/or hose end control valves (HECV) may be
used to adapt the nozzle to any fuel system.

TEST
1. General
Perform all tests using Stoddard solvent (or equivalent) as the test fluid, supplied by a 0 to 180 psig
(0 to 827 kPaG) test stand. Use only petroleum jelly as a lubricant to aid in the assembly of seals and
O-rings.
2. Functional Test
To functional test the nozzle (see IPL Figure 1), do as follows:
A. Place the nozzle in the test fixture (P/N F65-0-1130) and use handles (52, 52A or 52B) to rotate
nozzle clockwise and lock nozzle to test fixture.
B. Use knob (36) on cam handle (38) to set the position to OPEN and then to CLOSED.
Note: The cam handle (38) shall operate freely with no mechanical interference or binding. If
binding occurs refer to REPAIR section.
C. Use the handles (52, 52A or 52B) to rotate the nozzle counter clockwise to unlock it from the test
fixture.
Note: The nozzle shall lock and unlock freely from the test fixture without binding. If binding
occurs refer to REPAIR section. The nozzle body shall rotate approximately 30° when
connecting to the adapter. If nozzle over rotates, refer to the REPAIR section.
D. Do steps A thru D three times.
3. Leakage Test (Basic, G1, G2, H1, H2, L1, L2, N1, N2, and P)
Note: Adapter Swivel Assembly (71) must be installed on “BASIC” nozzle for leakage test. For Mods;
G, H1, L1, L2, N1 and N2; the lockout device p/n 941020-101 shall be installed in the vent port
of the nose end control valve.
A. Make sure the nozzle is in the CLOSED position (see Figure 1).
B. Place the nozzle in the test fixture (P/N F65-0-1130) and rotate nozzle clockwise to lock nozzle to
test fixture.

adapter to connect pressure source to test fixture (P/N F65-0-2083).
F. Test fixture (P/N F65-0-1130) has a 1/4 inch NPT tap for a test plug. Fill nozzle with test fluid and
let air bleed thru the hole in test fixture (P/N F65-0-1130). Plug up test fixture (P/N F65-0-1130)
after all air has escaped from the nozzle.
G. Apply 180 psig of fluid pressure to the nozzle for 5 minute. Then reduce pressure to 0 psig.
H. Use knob (36) on handle (38) to set the nozzle in the closed position.
I. Disconnect nozzle from test fixture (F65-0-1130).
J. Apply 180 psig of fluid pressure to the nozzle for 5 minute. Then reduce pressure to 0 psig.
K. There must not be any leakage from the exterior of the nozzle, thru any seals or from the plugs (3).
L. Remove all test fixtures from the nozzle.
4. Leakage Test (3, 3†, 4, 4†, 6, 6†, 7, 7†, 8 and 9)
A. Make sure the nozzle is in the CLOSED position (see Figure 1)
B. Place the nozzle in the test fixture (P/N F65-0-1130) and rotate nozzle clockwise to lock nozzle to
test fixture).
C. Rotate knob (IPL Figure 1, 36) on cam handle (38) and place the nozzle in the open position.
D. Install matching test plugs (P/N‟s 2878018, 2878019, 2878020 or 2878021) in the inlet port of the
nozzle under test.
E. Test plugs (P/N‟s 2878018, 2878019, 2878020 or 2878021) have a 1/4 inch NPT port for pressure
source. Attach appropriate connector to connect pressure source to the test plugs (P/N‟s 2878018,
2878019, 2878020 or 2878021).
