Model 463.323 (M612)

Highway

Details of installation of the fuel distributive highway (M612)

1 — the Basic arm of the pressure head line
19/1 — the TNVD Pressure head line
21 — the Fuel highway
21/3 — the Line of removal of oil
21/4 — the Line of return of fuel
21/6 — Fuel-supply lines of nozzles

22 — the Line of return of fuel from a cooler
23 — Sealing rings
B4/6 — the Sensor of pressure of the fuel highway
Y74 — pressure Valve regulator

 PERFORMANCE ORDER

  1. Remove panels of finishing of a cover of a head of cylinders.
  2. Disconnect an electrical wiring from the sensor (B4/6) and the valve regulator of pressure (Y74).
  3. Remove fuel-supply lines of nozzles (21/6).
  4. Disconnect from the fuel highway (21) pressure head (19/1) and returnable (21/4) lines, - for keeping of a nipple nut from a provorachivaniye use the second key.
  5. Remove the line of return of fuel from a cooler (22) and the line of removal of oil (21/3), - prepare replaceable sealing rings.
  6. Remove the fuel highway (21), in case of need remove nozzles (see below).
  7. Installation is made upside-down, - do not forget to replace sealing elements.
  8. In conclusion start the engine and check components of a fuel path for existence of signs of development of leaks, clear memory of the module of onboard self-diagnostics (see the Head Sistemy of electric equipment of the engine).

Nozzles

Details of installation of nozzles (M612)

 PERFORMANCE ORDER

  1. Remove panels of finishing of a cover of a head of cylinders (7 and 8).
  2. Disconnect an electrical wiring from nozzles (Y76).
  3. Remove fuel-supply lines (1).
  4. Release clamps (2) and remove the line of removal of oil (3), - use a cap key with a cutting head.
  5. Release clamps (2) and disconnect the maslootvodyashchy line (3), - clamps (2) are subject to replacement without fail.
  6. Remove clamps (4) and take nozzles (Y76).
  7. Installation is made upside-down, - do not forget to replace sealing elements.
  8. In conclusion start the engine and check components of a fuel path for existence of signs of development of leaks, clear memory of the module of onboard self-diagnostics (see the Head Sistemy of electric equipment of the engine).

Model 463.333 (M628)

Highway

Details of installation of the fuel distributive highway (M628)

1 — the Air cleaner
2 — Bolts
19/1 — the Pressure head line / the valvate block / the fuel highway

21 — the Fuel highway
21/6 — Fuel-supply lines of nozzles

 PERFORMANCE ORDER

  1. Remove the air cleaner (see the Section Service of Components of an Inlet Air Path).
  2. Remove fuel-supply lines of nozzles (21/6) and the pressure head fuel line (19/1).
  3. Turn out bolts (2) and remove the fuel highway (21).
  4. Installation is made upside-down, - tighten fixing bolts only after installation of pressure head lines.
  5. In conclusion start the engine and check components of a fuel path for existence of signs of development of leaks, clear memory of the module of onboard self-diagnostics (see the Head Sistemy of electric equipment of the engine).
