where other-
This section describes, illustrates, and furnishes the operator with sufficient information pertaining to the various controls, instruments, and related items for the proper operation of the nozzle tester.
The fuel reservoir (1A) contains the test fluid used to conduct tests when checking the performance of
- The fuel reservoir fuel injector nozzles; has a built in paper
type filter element (2D, fig. 3). The test
fluid is forced through the filter element by atmospheric pressure and pump suction.
11. Hydraulic Pressure Gage Valve
Assembly
The hydraulic pressure gage valve assembly (3C) stops the flow of the test fluid to the hydraulic pressure gage. Turn the valve handle (3B) left to open and right to close.
The hydraulic pressure gage (2) indicates the amount of pressure applied when testing the various types of nozzles.
The dial has a range of O to 5,000 psi
(pounds per square inch) and marked in increments of 50 psi.
13. Pump Handle Assembly and Handle Shoe
The action of the pump handle assembly
(4B) and handle shoe (4A) actuates the plunger built within the body and plunger assembly (4), and producing a hydraulic pressure which is recorded on the hydraulic pressure gage (2).
Section Ill. OPERATION
Note:
The key numbers shown below in parentheses in this section refer to figure 1.
This section contains instructions for the operation of the nozzle tester under conditions of moderate temperatures and humidity. Every organization equipped with this item must thoroughly train its personnel in the procedures for operating this item.
a. Mount the nozzle tester (fig. 1) on a
bench and secure with three 3/8-inch bolts, washers, and nuts. For portable use, mount on wooden or metal base 5 inches wide x
15 inches long. Use 3/4-inch plywood or l/2-inch sheet steel.
b. Slide the pump handle assembly (4B) onto the handle shoe (4A) located in the base of the nozzle tester. Solid shaft in the pump handle assembly may be extended or telescoped, depending on 1 e v e r a g e required.
c. Remove the fuel reservoir cover (lC) from the fuel reservoir (1A) with a combined twisting and pulling motion. Fill the fuel reservoir with test fluid and install the fuel reservoir cover.
d. Open the valve handle (3B) and make several strokes with the pump handle assembly (4B) to prime the nozzle tester.
Close the valve handle.
N o t e . A vent screw (4C) is located on the side of the housing behind the lower discharge outlet (3E) and can be opened for thorough venting and priming i f n e c e s s a r y .

a. Discharge Block Assembly. The discharge block assembly (3) has two discharge outlets to facilitate the various tests. When nozzle under test is connected to lower discharge outlet (3E) and with hydraulic pressure gage valve assembly
(3C) closed, this shuts off and protects the hydraulic pressure gage (2) during rapid and prolonged pumping periods when flushing nozzle or observing spray form. Using upper discharge outlet (3D) and closing hydraulic pressure gage valve assembly
(3C) isolates hydraulic pressure gage (2) and the nozzle under test from the nozzle
tester (fig. 1) permitting leakage rates or
pressure drop measurement tests.
Note. Install and tighten cap nut assembly (3F) on discharge outlet not in use.
b. Mounting Instructions. Mount the fuel injector nozzle to be tested on the nozzle tester in accordance with the connecting
instructions (fig. 2) using connector set

(3) may cause blood poisoning. Keep hands free of spray at all times.
Opening Pressure. Use lower discharge outlet (3E). Open the hydraulic pressure gage valve assembly (3C), operate the pump handle assembly (4B) slowly and, when nozzle begins to spray test fluid, observe the pressure indicated on the hydraulic pressure gage (2). This pressure should be compared with that specified by the engine manufacturer and nozzle adjusted, if necessary, before proceeding with further testing. Test should be repeated several times to be certain that nozzle consistently opens at the same pressure each time.
Spray Pattern.
Use lower discharge outlet (3E). Close the hydraulic pressure gage valve assembly (3C) and operate the pump handle assembly (4B) at approximately 15 strokes per minute.
Make sure that all spray holes are open and are spraying the same amount of test fluid. The spray formation should be sharp with a rather solid pattern and the angles formed by the individual sprays should be uniform. A missing section or uneven spray pattern indicates clogged or eroded orifices.
(4)
(5)
Sample spray patterns are generally shown in the engine manual.
Chatter. Use lower discharge outlet (3E). Close the hydraulic pressure gage valve assembly (3C) and operate the pump handle assembly
(4B) approximately two seconds.
The nozzle chatter must be distinct and regular. A sharp pitch sound is not mandatory, and an occasional skip or variation in the chatter sound pitch is acceptable.
When nozzle chatter is not satisfactory and does not improve with continued operation of the pump handle assembly, replace the nozzle.
Leakage. Use lower discharge outlet (3E). Open the hydraulic pressure gage valve assembly (3C) and opera t e pump handle assembly
(4B). During prolonged pumping, drops of test fluid should not form at tip of the nozzle. A second check for leakage can be made by maintaining pressure just below opening pressure and checking for test fluid leakage from tip. If this test is to be used, reconnect nozzle to upper discharge outlet (3D) and close the hydraulic pressure gage valve assembly (3C) to time pressure drop.
Some manufacturers specify permissible leakage rates.
CHAPTER 3

T h e primary function of preventive maintenance is to prevent breakdown and, therefore, the need for repair. These services consist generally of before operation and after-operation services performed by the operator. Intervals are based on normal operations, Reduce intervals for abnormal operations or severe conditions.
Intervals during inactive periods may be extended accordingly.
b. Definition of Terms. The general inspection of each item applies also to any supporting member or connection and is generally a check to see whether the item is in good condition, correctly assembled, secure and not excessively worn:
(1) The inspection for “good condition”
(2)
(3) is usually an external visual inspection to determine whether the unit is damaged beyond serviceable limits by the following not bent or twisted, not chafed or burred, not broken or cracked, n o t bare or frayed, not dented or colIapsed, not torn or cut, not deteriorated.
The inspection of a unit to see that it is “correctly assembled” is usually an external visual inspection to see whether it is in its normal assembled position.
Inspection of a unit to determine if it is “secure” is usually an external visual examination or an examination by hand or wrench for looseness. Such an examination must include any brackets, lockwashers,
(4) lock nuts, locking wires, or cotter pins used.
By “excessively worn” is me ant worn beyond serviceable limits or to a point likely to result in failure if the unit is not replaced before the next scheduled inspection.
a.. General. Any special cleaning instructions required for specific components or parts are contained in the pertinent section. Cleaning instructions are as outlined in (1) and (2) below. General cleaning precautions are contained in b below.
(1) Metal parts.
(a)
(b)
Use self-emulsifying decreasing solvent compound, mineral spirits paint thinner, or dry-cleaning solvent (Stoddard) to clean or wash grease or oil from all metal parts of the nozzle tester.
Use clean water or a solution of either 1/4 pound of soap chips or six ounces of painted-surface detergent to one gallon of hot water for all parts and overall general
(c) cleaning of painted surfaces.
After parts are clean, dry them thoroughly. Apply a light film of special preservative lubricating oil to all parts having a polished surface to prevent misting.
Before installing new parts, re(d) move any rust-preventive compound, protective grease, etc.
(2) Rubber Parts Other Than Electrical. Clean rubber parts with soap and warm water. Apply a coating of powdered technical talcum to preserve the rubber.
b. General Precautions in Cleaning.
(1) Self-emulsifying decreasing solvent compound, mineral spirits paint thinner, and dry-cleaning solvent are flammable and should not be used near an open flame.
Fire extinguishers should be provided when these materials are used Use only in well-ventilated places. These cleaners evaporate
(2) quickly and have a drying effect on the skin. If used without gloves, they may cause cracks in the skin and, in the case of some individuals, a mild irritation or inflammation.
Avoid getting petroleum products, such as mineral spirits paint thinner, dry-cleaning solvent, engine fuels, or lubricants, on rubber parts, as they will deterior-
(3) ate the rubber.
The use of Diesel fuel oil, gasoline, or benzene (benzol) for cleaning is prohibited.
c. Rust Removal.
Remove rust or corrosion from all parts of the materiel.
To remove rust or corrosion from unfinished surf aces, use steel cleaning brushes or abrasive cloth. On finished surfaces, other than highly polished surfaces, remove rust or corrosion by buffing with a rotary wheel wire brush constructed of steel wire between 0.010
and 0.025 inch in diameter. Crocus cloth may be used manually to remove rust or corrosion from polished surfaces.
24. Operator’s Preventive-Maintenance

CHAPTER 5
SHIPMENT AND ADMINISTRATIVE STORAGE AND
DEMOLITION TO PREVENT ENEMY USE
Section I. SHIPMENT AND ADMINISTRATIVE STORAGE
Shipping Instructions a.
Responsibility. When shipping the nozzle tester, the unit commander will be responsible for shipping the materiel, including all tools and equipment, adequately processed, packaged, and packed to protect it from damage until it reaches the echelon of maintenance for required repairs; or, in the case of troop movement, reaches its destination in a serviceable condition.
b. Army Shipping Documents. Prepare all army shipping documents in accordance with AR 725-50.
c. Preparation for Shipment. When the nozzle tester is removed from administrative storage for shipment it need not be reprocessed unless inspection reveals it to be inadequately preserved, or when it is necessary because of anticipated intransit weather or shipping conditions.
Preservatives must not be removed or disturbed, except as necessary, to insure that the nozzle tester is complete and serviceable. If preservatives are removed, they must be restored prior to shipment.
43. Preservation, Packaging, Pocking,
and Marking Instructions.
a. Preservation and Packaging. Preservation of the nozzle tester must be sufficient to protect it against deterioration and damage during shipment and administrative storage and/or the subsequent interval prior to use. Under no condition will tools and equipment with critical surfaces be packaged without benefit of sufficient preservation to assure adequate protection (TM 9-200). Preservation and packaging must be compatible with end use requirements.
b. Packing. Packed items must be acceptable to the carrier, while affording adequate protection to the items during shipment and administrative storage and/ or the subsequent interval prior to use.
c. Marking. All materiel will be marked in accordance with TM 9-200.
a. General.
(1) Unit commander? may, with the approval of major commanders, place the nozzle tester in administrative storage or return to supply agencies equipment that is beyond the maintenance capability of the unit. Nozzle testers must be stored in the most favorable 10 cation
(2)
(3) available, preferable one which affords protection from exposure to elements and pilferage.
All nozzle testers in administrative storage must be maintained so that they will be ready for immediate use and/or ready for shipment.
Administrative storage is restricted to a period of 90 days and must not be extended unless the nozzle tester is reprocessed.
b. Storage Procedures.
(1) Perform a quarterly preventivemaintenance (PM) service on the nozzle tester. This maintenance
(2)
(3) will consist of inspecting, cleaning, servicing, and preserving, as required, and will also include minor repair parts replacement (if required) not requiring highly technical skills or expensive, complicated, or bulky test equipment or tools.
Provide access to the nozzle tester to p e r m i t inspection, servicing, and removal from storage.
Mark the nozzle tester “Administrative Storage” (by use of tags or
other convenient method). The noz zle tester so marked must not be operated while in this category.
c. Inspection in Administrative Storage.
Visual inspection of the nozzle tester in administrative storage must be conducted at least once each month to detect corrosion and rust, When corrosion and rust are found, corrective action must be taken immediately. A record of these inspections must be maintained for each nozzle tester in administrative storage. The records must be attached to the nozzle tester in such a manner as to protect it from the elements.
Section Il. DEMOLITION OF MATERIEL TO PREVENT ENEMY USE
a. Destruction of the nozzle tester, when subject to capture or abandonment in the combat zone, will be undertaken by the using army only when, in the judgment of the unit commander concerned, such action is necessary in accordance with orders of, or policy established by, the army commander. When in the hands of maintenance personnel or in storage, destruction will be in accordance with FM 9-5 and the information below, when applicable.
b. The information which follows is for guidance only. Certain phases of the procedures outlined require the use of explosives and incendiary grenades which normally may not be authorized items of issue to the using organization. The issue of these and related materials and the conditions under which destruction will be effected are command decisions in each case, according to the tactical situation.
Of the several means of destruction, those most generally applicable are:
Mechanical . . . . Requires axe, pick mattock, sledge, crowbar, or similar implement.
Burning . . . . . . Requires gasoline, oil, incendiary grenades, or other flammables, welding or cutting torch.
Disposal . . . . . Requires burying in the ground, dumping in streams or marshes, or scattering so widely as to preclude recovery of essential parts.
*Demolition . . . Requires suitable explosive or ammunition.
*Gunfire . . . . , Includes artillery, machine guns, rifles using rifle grenades, and launchers using antitank rockets. U n de r some circumstances, hand grenades may be used.
In general, destruction of essential parts, followed by burning, will usually be sufficient to render the material useless. However, selection of the particular method of destruction requires imagination and resourcefulness in the utilization of the facilities at hand under the existing conditions. Time is critical.
c. If destruction to prevent enemy use is resorted to, the materiel must be so badly damaged that it cannot be restored to a usable condition in the combat zone either by repair or cannibalization. Adequate destruction required that all parts essential to the operation of the materiel be destroyed or damaged beyond repair. However, when lack of time and personnel prevents destruction of all parts, priority is given to the destruction of those parts most difficult to replace. Equally important, the same essential parts must be destroyed on all like materiel, so that the enemy cannot construct one complete unit from several damaged ones.
d. If destruction by demolition or gunfire is directed, due consideration should be given to the observance of appropriate safety precautions.
*Generally applicable only when nozzle tester is to be destroyed in conjunction with other equipment.
46. Destruction of the Nozzle Tester a. Method No. 1 - Destruction by Mechanical Means.
(1)
(2)
(3)
Open the carrying case and remove the nozzle tester, connector sets, hose, and spray collector cup.
Using an axe, pick mattox, sledge, or any other heavy implement, destroy the nozzle tester by smashing the body casting, fluid reservoir, and hydraulic gage,
Destroy the carrying case and spray collector cup by smashing.
Cut the hose in short lengths, and scatter the connector sets.
Elapsed time: about 2 minutes.
b. Method No. 2- Destruction by Burning,
(1) Open the carrying case and remove the nozzle tester, connector sets, hose, and spray collector cup.
(2) Using a welding or cutting torch, burn through the body casting, fluid reservoir, hydraulic gage, carry-
(3) ing case, spray collector cup, hose, and connector sets.
In the absence of a welding or cutting torch, place piles of combustible materiel on and about the nozzle tester. Pour gasoline or oil over the combustible materiel and the nozzle tester, ignite by means of an incendiary grenade fired from a safe distance, by a combustible train of suitable length, or other appropriate means. Take c o v e r immediately. A hot fire is required to render the materiel useless.
Elapsed time: about 4 minutes.
Warning: When igniting gasoline, due consideration should be given to the highly flammable nature of gasoline and its vapor. Carelessness in its use may result in fatal or painful burns.
c. Method No. 3- Destruction by Dis-
posal. Bury the nozzle tester in a suitable hole or throw it into a stream.
Elapsed time: about 2 minutes.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share, republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please provide a link to liberatedmanuals.com, so that free manuals come up first in search engines:
