GENERAL MAINTENANCE

17. General

This cha pter provides th e n e o e s s a r y i n -s t ruc t ions on the general maintenanceprocedures to follow. The followingmeth-ods and procedures given in this chapterar e to be car efully observed dur ing repa iropera tions. This cha pter includes t he dis-assembly and assembly procedures, re-placement of par ts , use of tools, cleanin g,f inished surfaces, removal of burs . andtn s t ruc t ions on lubrication.13. General Repair Methods

a. Disassembly and Assembly Procedures.(1) In disassembling a unit, remove

the major subassemblies and as-semblies whenever possible. Sub-assemblies may be disassembled,as necessary, into individual parts .

(2) During assembly. subassembliesshould be assembled first, theninstalled to form a complete unit.Lubricate all component partslightly before assembling.

(3) Complete disassembly of a unit isnot always necessary in order tomake a required repair or re-placement. Good judgment shouldbe exercised to keep disassemblyan d assembly operat ions t o a m i n -imum .

b. Replacement of Parts.0)

(2)(3)

When assembling a unit, replace

all pins when necessary. Replacegrip screws or bushings whendamaged.All spr ings will be replaced if theyare broken. bent, cracked or if theyfail t o function properly.If a r equired new part is not avail-able, a reconditioned used partmay be substituted. Such recondi-tioned used parts will be examinedcarefully to determine their serv-iceability.

c. Use af Tools(1 ) Care must be exercised to use tools

that fit and are suitable for the taskto be performed in order to avoidunnecessary mutilation of partsand/or damage to tools.

(2) Special tools are listed in tab le 1and are provided for the mainte-

nance of the m at eriel. These toolswill be used only for the purposefor which they are intended.

(3) Keep tools clean and work withclean parts. Normal rules of goodhousekeeping must be observed.

19 . Cleaninga. As assemblies are removed and dis-

assembled, component items should beplaced in a wire basket a nd cleaned t hor-oughly of all grease, oil, water and dirt,using dry cleaning solvent (SD). Drythoroughly with clean wiping cloths andoil lightly us ing general pu rpose lubricat -ing oil (PL special).b. Clean the barrel bore, chamber, and

all parts that come in contact withpowderresidues, using solvent cleaning compound(PD 126). Cleaning rod IvI4, 5564102 (fig.4) and small arms cleaning brush M5.5504036 (fig. 4) are used to clean thebarrel bore. Saturate brush with PD 126and run through barrel. Remove brush,clean the rod, insert two swabs in slot ofrod and dry the bore thoroughly or untilswabs appear clean after running throughbore. Then use one swab saturated withPL special t o oil inside of bore lightly anda ll exterior surfaces to prevent corrosionor rust.

c. On those component parts whichcon-ta in a ha rd carbon r esidue, it ma ybe nec-essary to clean these parts with carbonremoving compound (P-C-111A). Cleaninginstructions are as follows:

Warning: Avoid skin cont act. Th e com-pound should be washed off thoroughly withru nn ing water if it comes tn contact with

18

the skin. A good lanolin base cream, afterexposure to compound, is helpful. The useof gloves and protective equ tpmen t isrecommended.

(1) Using a suitable container, fill with

fresh compound.(2) Before soaking components remove

loose grease; dirt and oil fromparts as indicated inparagraph 19a.Imm erse par ts, cont aining car bonresidue, in container. ,Allow barrel to soak for 2 hoursor until all traces of carbon havebeen removed.Rinse with water, kerosene, orsolvent . To effectively r emove car -bon, brush with a stiff bristle

brush under r unn ing water.Wipe the parts dry and oil.

Note: P-C-IIIA is considered a supp lemen t foruse in direct end general support meintenenoe levelsonly in extreme cases and not as a substitute forP D 126.d. Clean receiver, using dry cleaning

solvent (SD).e. On components that contain an ac-cumulation of light rust, use a clean clothmoistened with PD 126. If this does notsuffice, use crocus cloth. Make certain it

does not scra tch or a lter t he finished sur -faces. Remove all dirt and abrasives; oilsurfaces before assembling parts.

f . N ew material and component parts,received from storage for immediate use.ma y have hea vy accum ulat ions of grease.Place material or components in wirebasket and lower in vapor degreasing vator wash in dry cleaning solvent (SD). Dryth oroughly as indicat ed in par agraph 19aand oil. Lubricate as specified in para-graph 23b.

g . For cleaning instructions of Ordnancemateriel. refer to TM 9-208-l.

20. General Precautions in Cleaninga. Dry cleaning solvent (SD) is flam-

mable and should not be used near an openflame. Fire extinguishers shouldbe readilyavailable when using these materials. Inaddition, they evaporate quickly and havea drying effect on the skin. When usedwithout rubber gloves, they may cause

cracks in the shin, and in the case of someindividuals, a mild irritation or inflamma-tion. Use only in well-ventilated places.

b. The u se of diesel fuel oil. gasoline orbenzene (benzol) for cleaning the weapon

is prohibited.c. Store solvent cleaning compound (PD

126) in a warm place, if practical. Do notdilute or add an tifreeze.

Note: Sandblasting is permissible on nonworkingsurfaces for removal of dirt and rust.

21. Finished Surfaces

a. All treated surfaces will be refinishedto match the appearance of new parts.

b. For detailed information on finishedsurfaces, refer to TM 9-1861.

22 . Removal of Burs, Screwheodsand Working Surfaces

a. During the entire life of the pistol,polishing and stoning are necessary to re-lieve friction and to remove burs causedby usage. Burs on screwheads and likesurfaces should be removed with a finefile or stone. Burs on such working sur-

faces as the receiver sliding rails, re-ceiver housing areas and bearings shouldbe removed with a file or stone and polishedwith crocus cloth.

Cau tmn : Care will be exercised to stoneor file evenly and lightly and not removemore metal than absolutely necessary tomaintaincorrect contours. Critical dimen-sions of parts or assemblies must not bealtered in any way that would affect thefunctioning or interchangeability of parts.

b. Roughspotscausedbyscores, galling,gouges and rust pits will be smoothed toenable all part s t o operat e normally. Thefinish of the repaired component will beapproximately that of the original finish.

23. Lubrication

a . Make cer ta in a l l meta l par ts are

cleaned and dried thoroughly in accord-an ce with instr uctions cont ained in par a-

graph 19.
