Model-specific safety

The safety lever also covers the charging handle slot. With the lever up on SAFE the bolt cannot travel far enough to inspect the chamber properly — rotate it down before clearing.
The magazine rocks in and out and is not released by a button. Rock it forward and out.
The recoil spring assembly is under compression and springs rearward when the dust cover is removed.
Gas system parts are extremely hot after firing.
Surplus ammunition may be corrosively primed. Clean with a water-based solvent the same day you shoot.

Shop difficulty

Shop tier 2 Tier 2 — moderate among rifles and carbines, for the full job: strip to the parts that get coated and put it back together working. A riveted receiver with nothing to fit, but the trigger group goes in against the hammer spring with the pins held by a single retaining spring, and the handguard retainer, gas tube lock and selector are notoriously tight. No timing and no special fixtures. A middle-of-the-range rifle job.

Parts: 66 numbered parts (stand-in, weak: no AK-74 itemised list was found; this is the 7.62x39 Mitchell Arms 'AK-47 Autoloading Rifle' (semi-automatic Yugoslav-made AK/AKM-pattern import) per the Gun Digest exploded drawing l), from The Gun Digest Book of Exploded Gun Drawings (975 isometric views) - Mitchell Arms 'AK-47 Autoloading Rifle' — Gun Digest Books / Krause Publications (scan on archive.org), p. book p. 714 (PDF page 715) archive.org [11].

Bench time: about 45 min to strip, 60 min to rebuild (estimate). Estimate: field strip plus trigger group (hammer, trigger, disconnector, springs, pins and retaining spring), selector, handguards and retainer, gas tube, pistol grip, stock, rear sight leaf/slider, front sight and muzzle brake and spring-loaded detent pin. Rebuild longer for the hammer spring and pin retainer under tension and the handguard retainer. Receiver, trunnions and rivets stay as they ar

Small parts: 7 pins, 13 springs, 3 detents or plungers (counted by name in the same legend (all 66 keys). Pins: 2, 5, 9, 28 hammer and trigger pin, 37 folding stock hinge pins, 45, 64 securing pin (12 firing pin not counted). Springs: 1, 6, 7, 10, 11, 20, )

What comes off for coating

Fire control group: pin retaining spring (shepherd's crook), hammer, hammer spring and pin, trigger, disconnector, disconnector spring and pin, safety selector — drift punch, rubber band or slave pins for the hammer spring
Receiver and barrel: dust cover, recoil spring assembly, bolt carrier and bolt (firing pin, extractor, extractor spring and pin), gas tube/upper handguard, lower handguard and retainer, rear sight leaf and slider, front sight post/hood, muzzle brake and spring-loaded detent pin — AK front sight tool
Furniture: pistol grip and nut/screw, buttstock and tang screws, butt plate, cleaning rod

Special tools

AK front sight adjustment tool — Front sight post (only if moved)
Slave pins / rubber band — Holding the hammer spring and trigger parts during pin installation
Small punch for the firing-pin and extractor pins — Bolt strip
Pistol grip nut driver (long screwdriver) — Pistol grip screw through the grip

Known pain points

Getting the trigger group out means lifting the hammer spring (mainspring) legs and hooking them behind the hammer ears, then holding them there while the trigger pin comes out. Reassembly reverses this under spring load, with the pin retaining spring ('shepherd's crook') laid over the pins. (both)
Source: 12 Hidden Features of the AK-47 Cleaning Kit — The Firearm Blog thefirearmblog.com [9] — “During disassembly, you must raise the mainspring ends and catch them behind the hammer “ears” to release the tension from the trigger for further disassembly.”
Once hooked, the mainspring legs have to be held while the pins move, typically with a rubber band or the cleaning-kit cap. (both)
Source: 12 Hidden Features of the AK-47 Cleaning Kit — The Firearm Blog thefirearmblog.com [9] — “Once mainspring ends are hooked to the hammer, they must be somehow retained.”
The gas tube lock lever and the lower handguard retainer are often very tight and need a tool to rotate. (both)

The selector lever is a spring-steel part held by its own tension and can be bent while being worked out of the receiver. (both)

Fit or check on rebuild

Function check (disconnector, safety) — The hammer spring legs and disconnector spring must be seated correctly; check that the safety blocks and the hammer resets
Front sight/zero — Front sight and muzzle device moved for coating mean a re-zero
Handguard and gas tube lock fit — Coating build-up makes the retainer and gas tube levers even tighter; check that they lock

Procedures

Clear and Make Safe

Clear & Make Safe

Point the muzzle in a safe direction and keep your finger off the trigger.
Rotate the safety lever down to the fire position so the charging handle can travel fully rearward.
WarningWith the lever on SAFE, bolt travel is deliberately restricted and you cannot properly inspect the chamber.
Rock the magazine forward and out of the magazine well.
Removed at this step: Magazine
Pull the charging handle fully to the rear and hold it there. Look into the chamber and the magazine well.
Physically feel the chamber to confirm it is empty.
WarningMost AK variants have no bolt hold-open, so you must hold the bolt back yourself. Keep fingers clear when you release it.
Ease the bolt forward and remove all live ammunition from the work area.

Field Strip

Complete the Clear and Make Safe procedure.
Press in the recoil spring guide rod tab protruding through the rear of the dust cover.
Lift the rear of the dust cover up and pull it back and off.
WarningThe recoil spring assembly is compressed behind it. Keep a hand over the rear of the receiver.
Removed at this step: Dust cover
Push the recoil spring assembly forward to clear its seat, then lift it out.
Removed at this step: Recoil spring assembly
Pull the bolt carrier fully rearward to the cutout in the receiver rails and lift it up and out.
Removed at this step: Bolt carrier and bolt
Rotate the bolt to unlock it from its cam track and pull it forward out of the carrier.
Removed at this step: Bolt
Rotate the gas tube lever upward until vertical, then lift the gas tube and upper handguard off.
Removed at this step: Gas tube and upper handguard

Reassembly

Set the gas tube and upper handguard into the front trunnion recess, seat the rear, and rotate the lever down to lock.
Insert the bolt into the front of the carrier and rotate it so its lug engages the cam track.
Set the carrier into the receiver rails with the bolt forward, engage the gas piston into the gas tube, and slide it forward.
Set the recoil spring assembly into the carrier channel and push it forward until the guide rod seats.
Set the front lip of the dust cover into its recess, then press the rear down until the guide rod tab snaps through its hole.
WarningIf the tab is not protruding through the dust cover, the cover will come off under recoil.
Cycle the action several times and perform the function check.

Torque specifications

No sourced torque values from the manufacturer are recorded for this firearm. Where a fastener has a specified torque — action screws, scope bases, muzzle devices, barrel nuts — get it from the manufacturer or a gunsmith rather than estimating it.

What the manufacturer does say: The official military manuals give no torque value. They say: "2) Исправность приклада: винты затыльника должны быть полностью завинчены, шлицы винтов очищены;" [translation by this project: "2) Condition of the butt stock: the butt-plate screws must be fully screwed in and the screw slots cleaned;"] (Руководство по 5,45-мм автомату Калашникова (АК-74, АКС-74, АК-74Н, АКС-74Н) и ручному пулемету Калашникова (РПК-74, РПКС-74, РПК-74Н), PDF p. 31 (inspection of the assembled weapon))

Reported by other sources — not the manufacturer

Not a manufacturer specificationThese values come from the people and publications named beside each one, not from Izhmash / Kalashnikov Concern. They are recorded with who said them and their exact words so you can judge them — not as a recommendation. Confirm any of them with the manufacturer or a licensed gunsmith before you put a wrench on your firearm; a wrong value can crack a stock, strip a thread or loosen a muzzle device.

Function check

After every reassemblyPerform these checks on a verified-unloaded firearm. If any check fails, the firearm is not safe to fire — stop and see a licensed gunsmith.

Verify the rifle is unloaded with no magazine inserted before each step.
With the safety lever on SAFE, confirm bolt travel is restricted and the trigger does nothing.
Rotate the safety to FIRE, charge the rifle, and press the trigger. The hammer should fall.
Hold the trigger back, charge the rifle, and release slowly — you should hear the disconnector click.
Confirm the dust cover is locked down and the recoil spring tab protrudes through it.
Confirm the magazine rocks in and locks positively.

Maintenance

Lubrication points

Bolt lugs and body
Carrier rails
Cam track in the carrier
Gas piston (a light film only)
Hammer and trigger pivots

Cleaning notes

Corrosive surplus primers leave salts that rust a bore within days. Flush the bore, gas tube, piston, and bolt face with hot soapy water or a water-based solvent the same day, dry completely, then oil. Keep the firing pin channel dry — a firing pin held forward by congealed grease causes slam fires.

Suggested inspection interval: roughly every 1000 rounds. This is a general guideline, not a manufacturer specification.

Wear parts to inspect

Recoil spring · Firing pin (check it moves freely) · Extractor and spring · Gas piston · Rivets and trunnion on high-round-count rifles

Common issues

Symptom	Likely cause	What to do
Dust cover flies off when firing	Recoil spring guide tab not seated through the dust cover hole	Reinstall and confirm the tab protrudes and locks.
Slam fires or doubling	Firing pin stuck forward in a cosmoline-packed or fouled bolt	Stop firing. Strip the bolt, clean the firing pin channel until the pin rattles freely, and reinstall dry. see a gunsmith
Rust days after shooting	Corrosive primer residue	Clean with a water-based solvent the same day, dry, and oil.
