Removal and installation of the inlet pipeline / a final collector
|
|
Before starting procedure performance allow to the engine to cool down completely. |
|
|
As the inlet pipeline and a final collector have the general lining, their removal is usually made simultaneously. All hairpins and bolts should before отдаванием be moistened by getting oil. |
Removal
|
|
Disconnect a negative wire from the battery.
Moisten with getting oil of a carving of hairpins of fastening of a final collector and fastening bolts to a collector of a reception pipe of system of release of the fulfilled gases.
Remove air cleaner assemblage (the Head of the Power supply system and release of the fulfilled gases).
Disconnect cables of gas, a drive throttle заслонки in a mode kik-daun (only models with АТ) and темпостата (if it is provided) from the throttle case.
|
|
Disconnect from the case of a throttle cables of gas, a drive throttle заслонки in a mode kik-daun and темпостата (if it is provided).
|
Mark and disconnect from a final collector all vacuum lines and electric sockets.
Dump pressure of fuel and disconnect lines of giving and return of fuel from assemblage of a fuel highway (the Head of the Power supply system and release of the fulfilled gases). Закупорьте the open ends of lines.
Loosen the a tension tape drive a belt (the Head of Adjustment and routine maintenance).
Remove from the inlet pipeline the pump of system of hydrostrengthening of a wheel with an arm and put aside, without disconnecting from it hoses. Take care of that the pump has been established downwards by a bottom in avoidance вытекания from it a hydraulic liquid.
Remove a fuel highway with injectors (the Head of the Power supply system and release of the fulfilled gases).
Give nuts/bolts of fastening of the inlet pipeline.
|
|
Access to four of elements of fixture of the inlet pipeline (arrow) is possible from above - for отдавания the remained four elements it is necessary to reach under the pipeline.
|
Slightly delay the pipeline from the engine, removing from directing pins on a head of cylinders, then take it from an impellent compartment.
Give two bolts and nuts of fastening of a final collector to a reception pipe of system of release of the fulfilled gases and disconnect a pipe from a collector. A sealing ring throw out.
Remove a final collector.
|
|
Installation
|
|
Carefully smooth out interfaced surfaces, having removed with all of them traces of a material of an old lining.
If the pipeline/collector is subject to replacement, track, that on replaceable from the old all fixture has been transferred.
Establish on a head of cylinders a new lining, having taken advantage for its fixing by directing plugs. Establish a final collector and tighten manually nuts.
Freely establish on a head of cylinders the inlet pipeline.
Establish fixing bolts of the pipeline and tighten all fixture in the order shown on an accompanying illustration with demanded effort. Pay attention that efforts of a tightening of extreme bolts differ from the other.
|
|
Order of a tightening of fixture (bolts/nuts) of the inlet pipeline / a final collector.
|
Installation of the remained components is made in an order, the return to a removal order. In knot of a joint of a reception pipe of system of release of the fulfilled gases and a final collector the new sealing ring is established.
Start the engine and check up it on leaks of the fuel, fulfilled gases and depression loss.
