2 EATON Aerospace Group TF100-107E May 2013 Eaton’s Carter product line is the leading manufacturer of nozzles qualified in accordance with SAE AS5877 (MIL-N-5877). Eaton’s Carter Model 64349H underwing refueling nozzle is listed as being qualified on the QPL. The specification defines four nozzles, D-1, D-1R, D-2 and D-2R. The D-1 and D-1R nozzles have an inlet body that includes a 45° elbow. The D-1R is a D-1 with the addition of a hose end regulator. The D-2 and D-2R (includes a regulator) have straight inlets. Both units have a military standard 6-bolt inlet flange in accordance with MS3378640. In addition Model 64349 can be purchased with various options to tailor a nozzle to fit the system requirements. These additional options, although widely utilized in the military, are not covered by any particular specification. New Inlet Option Model 64349 is now available with a D-3 inlet coupling that can be changed from the D-1 to the D-2 configuration and vice versa. This can be done without tools simply by swiveling the inlet to the configuration (0-45° and all angles in between) desired. The new D-3 variable inlet has been approved for use and is listed on the QPL. This option can be procured as Option N to the basic nozzle and it would replace either Option H or J. Features • Easy swiveling under all conditions. Swivel independent of quick disconnect (QD) coupling. • Connects to 3-lug international standard aircraft adapter (MS24484 or MS29514) • Lead-in ramps of stainless steel, not aluminum bronze, for longer life • Self-adjusting pressure loaded nose seal. No mechanical adjustments or springs used. Leak free under extreme side loads, worn adapters and extreme temperatures. • Nose seal can be changed with minimal disassembly. Arctic nose seal available. • Positive mechanical interlock prevents fuel flow until nozzle is secured to aircraft adapter. Nozzle cannot be disconnected from aircraft until closed. • Flow control handle fully protected from damage. Two styles available. • Flow control handles of high strength zinc-aluminum alloy • Bicycle-type handles for ease of operation. Circular grip also available. • Lightweight and rugged • Modular construction. Optional inlet configurations include dry break disconnect and strainer ball valve. • Hose end regulator and strainers optional • Two bonding cables, vacuum breaker optional. • Low pressure drop, under 12 psi (0.827 bar) at 600 USgpm (2,271 l/min) Design Concepts 61656 Blockout Device The blockout device is recommended for use when one defuels through a hose end regulator or it is necessary to check out the secondary pressure control device in a system. The blockout device does not introduce fuel into the ambient port of the regulator which can later become a dangerous spray during operation. 61607 Ball Tool The ball removal and installation tool is utilized to collect and automatically count the balls used in the swivel joints of the nozzle. It is simple to use and assures that the proper installation is achieved. A minimum of two tools are required for the simplest of nozzle configurations (one for the collar swivel and one for the hose swivel). Three are required for a nozzle having a regulator or a ball valve. 64000 Poppet Adjustment Gauge This simple inexpensive gauge provides an accurate method of achieving the proper adjustment of the poppet of Model 64349 nozzle. The gauge can be used on all Eaton underwing nozzles except Models 64200 and 64250. Use gauge 64250ST-1 for these later style nozzles. Special Tools Specially designed tools are recommended for the maintenance of Model 64349 nozzles.
