Removal

 PERFORMANCE ORDER

1. Disconnect a negative cable (-) of the rechargeable battery at the switched-off ignition. It is previously necessary to remove a box of the filter of air of salon.

Before a detachment of a cable find out a protective code of the radio receiver if that is available, address the Section Replacement of the Rechargeable Battery.

2. Engine 112: Remove the top cover of the engine or the air filter from covers of a head of cylinders.
3. Release the electric wires going to injectors. Mark the provision of a connector of cables for simplification of the subsequent installation.
4. Disunite sockets of injectors, having pressed a wire bracket.
5. Dump fuel pressure, address the Section Dropping Pressure in fuel system.
6. Disconnect a fuel-supply line from the fuel distributive highway. At emergence of the following fuel wipe it with a rag.
7. C32AMG: Remove the top part of the distributor of the forced air up.
8. Disconnect the fuel distributive highway and take out it together with injectors from the inlet pipeline.
9. Remove a lock bracket sideways of an injector and take out an injector from a distributive pipe.


Installation

 PERFORMANCE ORDER

1. Put on injectors (2) novyeuplotnitelny rings (3) and (4) and slightly grease them.

2. Insert injectors into the fuel distributive highway and record it a lock bracket (1) so that the bracket entered a tetrahedral guide of an injector.
3. Check sealing rings on the fuel distributive highway, if necessary, replace. Oil rings before installation pure motive.
4. Insert the fuel distributive highway with injectors into the inlet pipeline or on the lower part of the distributor of the forced air and fix by effort 9 Nanometers.
5. Fix a fuel-supply line on a pipe by the moment of 38 Nanometers.
6. Establish into place the top part of the distributor of the forced air.
7. Join sockets of injectors and record. Lay a cable as it passed before removal and record a connector.
8. Establish the top cover of the engine or the air filter.
9. Attach a negative cable (-) to the rechargeable battery at the switched-off ignition. Establish into place a box of the filter of air of salon. Enter a code of the radio receiver and determine time on hours.
