Removal and installation of the fuel highway and injection injectors

Components of an injector of injection

1 — the Fixing cap
2 — the Insulator
3 — the Injector
4 — the Top sealing ring

5 — the Central sealing ring
6 — the Bottom sealing ring
7 — the Insulator of the fuel highway


See preventions at the beginning of pressure Sbrasyvaniye's Section in a power supply system.

On models since 1995 вып. service of injectors of injection of a forward number of cylinders can be made without removal of the top section of the inlet pipeline. Dismantle of the fuel highway also is not the obligatory requirement.


 PERFORMANCE ORDER

1. Dump pressure in a power supply system (see. Undressed Sbrasyvaniye pressure in a power supply system).
2. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for equipment input in action!

3. Remove the top section of the inlet pipeline (the delivery chamber) (see. Part SOHC Engines or DOHC Engines of Head Engine).

4. Disconnect electroconducting from injection injectors.

5. For carrying out service of an injector (ов) turn out screws of fastening of a fixing cap (ов) and take an injector (ы) from assembly of the fuel highway. Estimate a condition of sealing rings of each of the removed injectors, defective rings replace. Before installation of injectors grease sealing rings with liquid lubricating oil.

At all do not use for greasing of rings silicone greasing, is can lead to obstruction of injectors! Easy rotary progress plant an injector (ы) to the highway. Wipe and establish fixing cap (ки) and tighten fixing screws with demanded effort.

6. For removal of the fuel highway disconnect from it lines of giving and fuel return, then turn out fixing bolts (on two from each of the parties).

7. Slightly shaking highway assembly here and there, remove it assembled with injectors from the bottom section of the inlet pipeline.

8. Installation is made upside-down. Pay attention to the next moments:

a) Do not forget to check a condition of insulators of support of the highway, defective components replace;
b) Having planted insulators in the bottom section of the inlet pipeline, slightly grease them with lubricating oil.
