6. CLEANING

6.1 CLEANING INJECTOR

The injector must never be cleaned

with a steel brush or pressure

cleaning equipment. Never put the

brush in the injector bores when

cleaning the exterior of the injector

nozzle. If this happens, the nozzle

must be replaced.

Before cleaning the nozzle, cover the

injector bores. Only clean the

injector with a brass hand brush.

Note:

The use of steel brushes can cause deformation

of the injector bores, with the result that the wrong

amount of fuel is injected.

This deformation cannot be ascertained by

measurements or checks.

Note:

The disassembly and assembly of injectors is not

permitted. Only external cleaning is permitted.

1.

Remove the injector. See "Removal and

installation".

2.

Clean the injector hole in the cylinder head.

The metal surface of the hole must not be

damaged.

3.

Wipe the exterior of the injector with a clean,

lint-free cloth. In the case of heavy soiling the

injector may be cleaned carefully with a

brass hand brush (not the apertures in the

injector nozzle!).

4.

Fit the injector. See "Removal and

installation".
