MAINTENANCE, OVERHAUL & TEST INSTRUCTIONS
CARTER PART NUMBER 64200 PRESSURE FUELING NOZZLE
1.0 INTRODUCTION
This manual furnishes detailed instructions
covering the maintenance and overhaul of
Carter Part Number 64200, Pressure
Fueling Nozzle and its various options. For the maintenance of options to the basic
64200 Pressure Fueling Nozzle, refer to
Options Table, Section 3.0. This table will
reference the service manual that should
be used in the maintenance of each option.
2.0 EQUIPMENT DESCRIPTION
The Carter Ground Fueling part number
64200, Pressure Fueling Nozzle, is a 2
1/2 inch Pressure Fueling Nozzle that has
been qualified to appropriate sections of
the new SAE AS5877 Nozzle
Specification released (or in the process
of being released at the time of
publication of this manual) to cover both
commercial and military nozzles. Prior to
its production release over 35 prototype
nozzles were subjected to field evaluation
at various environment locations around
the world. Changes were then
incorporated in the production version to
agree with the suggestions and minor
problems encountered by the using
customers. The unit is designed to mate
with adapters conforming to AS24484
(superseded MS24484) or equivalent.
The 64200 is intended to replace the
64348 as the standard nozzle provided by
Carter. The 64200 Nozzle is completely
different from the previous 64348, although
all mating accessories currently furnished
on the 64348 will work on the 64200.
The major differences lie in the
simplification in the design to remove
parts, especially moving ones on the
outside of the units. In addition, the
interlock system, previously depended
upon pins to mate with the aircraft
adapter, has been revised to remove the
pins. The interlock system is a part of
the replaceable nose seal and will be
updated with each replacement of the
nose seal. This interlock system will
prevent any wear of the slots, since it
does not even use the slots, on the
adapter. This is a great advancement in
safety and cost savings. Aircraft adapter
slots will not become worn because of the
interlock system on the Carter nozzle.
Reducing the wear of the slots reduces
the chance of an accidental removal of
the nozzle with it open causing a fuel
spill.
NOTE:
The 64200 interlock system depends upon
the three lugs on the adapter being within
the industry standard wear limits. Wear
limits are specified in SAE document
ARP5298 – Adapter Wear Limits. A copy
can be obtained from Carter distributors or
through Carter direct. See note later in this
section regarding potential problems if
adapter lugs are worn.
Other features of the new 64200 include:
•
A six-slot arrangement is included for
installing the nozzle onto the aircraft
making it easier to install.
NOTE:
If the 64200 has been installed on an
adapter that has lugs with wear beyond
the industry standard limits it may be
difficult or impossible to install on the next
aircraft. To fix, simply hold nozzle onto
adapter and turn it counter-clockwise to
move locking ring into the correct
position, then turn it clockwise to install
onto adapter.
If this occurs it is suggested that the
aircraft operator be told of the worn
condition so that the adapter can be
replaced at the earliest opportunity.
If the last adapter to which the nozzle
was attached is on the refueling
vehicle replace the adapter as soon as
possible.
•
Replaceable wear rings have been
added to the various attaching options to
improve the life of the swivel joint. (Note:
All older options that attached to the
previously qualified nozzles, 61429 and
64349, will mate with the newer 64200).
