Highway

Details of installation of the fuel distributive highway on models 163.113 (the series 612 engine)

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

Details of installation of the fuel distributive highway on models 163.113 (the series 612 engine) are shown on an illustration to which all references which are found in the text belong. Remove panels of finishing of a cover of a head of cylinders. Disconnect an electrical wiring from the sensor (B4/6) and the valve regulator of pressure (Y74). Remove fuel-supply lines of nozzles (21/6). Remove from the fuel highway (21) pressure head (19/1) and returnable (21/4) lines. Remove the line of return of fuel from a cooler (22) and the line of removal of oil (21/3). Remove the fuel highway, in case of need remove nozzles (see below). Installation is made upside-down, - do not forget to replace all sealing elements. 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

PERFORMANCE ORDER

Details of installation of nozzles on models 163.113 (the series 612 engine) are shown on an illustration to which all references which are found in the text belong. Remove a broad tank of the cooling system. Remove panels of finishing of a cover of a head of cylinders (7 and 8). Disconnect an electrical wiring from nozzles (Y76). Release clamps (2) and remove the line of removal of oil (3). Remove clamps (4) and take nozzles (Y76). Installation is made upside-down, - do not forget to replace sealing elements. 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).

Highway

Details of installation of the fuel distributive highway on models 163.128 (the series 628 engine)

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

Details of installation of the fuel distributive highway on models 163.128 (the series 628 engine) are shown on an illustration to which all references which are found in the text belong. Remove the air distributor (see the Section Service of Components of an Inlet Air Path). Remove fuel-supply lines of nozzles (21/6) and the pressure head fuel line (19/1). Turn out bolts (2) and remove the fuel highway (21). Installation is made upside-down, - tighten fixing bolts only after installation of pressure head lines. 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 on models 163.128 (the series 628 engine)

1 — Screws 2 — the Cover 3 — the Screw 4 — the Inlet air duct of a path of pressurization 5 — the Screw 6 — a nozzle Fuel-supply line	7 — the Clamp 8 — the Line of removal of oil 9 — the Screw 10 — the Clamp 11 — the Sealing ring Y76 — the Nozzle

PERFORMANCE ORDER

Details of installation of nozzles on models 163.128 (the series 628 engine) are shown on an illustration to which all references which are found in the text belong. Remove the air distributor (see the Section Service of Components of an Inlet Air Path). Remove the left air duct (4). Remove the left forward wheel and a loker of protection of a wheel arch. Disconnect an inlet air duct from a cover of a head of cylinders and take it aside. Uncover right and left nozzles (2). Disconnect from nozzles an electrical wiring and fuel-supply lines (6). Release clamps (7), then remove and take aside lines of removal of oil (8). Clamps is subject to replacement without fail! Remove clamps (10) and take nozzles (Y76). Installation is made upside-down, - do not forget to replace sealing elements. 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).
