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.
