Before removing the present injectors, thoroughly clean the area around each injector.
1. Pull out the injector.
2. Remove the copper sealing ring (A) from the base of the injector
shaft (C); we recommend using an extractor for diesel injector seals,
e.g. BGS 62630 or 62630-1 for this purpose.
3. The injector nozzle port (B) sealed to the base of the injector shaft
(C). For this purpose, screw a sealing plug (7) onto the mounting rod
(6) and insert a sealing plug (7) into each injector nozzle port. The
sealing plugs are dimensioned such that they fit into most injector
nozzle ports.
4. Remove the mounting rod (6) by turning anti-clockwise and leave
the sealing plug (7) in its position.
5. Select a brush with the matching size (2, 3 or 4) and attach to the
quick action chuck (5).
6. When selecting the brush size, observe that the injector shafts are
conical and become more narrow towards the seat surface (D).
7. Insert the quick action chuck (5) into a cordless drill and clean the injector shaft walls (C). Proceed
with care during work and make sure that all carbon and dirt residues are removed. When using the
cleaning brushes, take care that the end of the brush does not get caught in the sealing plug (7).
8. After cleaning, hold the sealing plug (7) in position using the mounting rod (6) and vacuum clean the
injector shaft.
9. Select a cleaning brush for the seat surface with the matching size (8 or 9) and
attach to the quick action chuck (5).
10. Press the steel spiral mounted on the bristles of the brush to approx. 5 mm before
the end of the bristles downwards. The purpose of the steel spiral is to keep the
bristles bundled and straight.
11. When the bristles are worn, position the steel spiral further upwards so that the
steel spiral is located 5 mm in front of the bristle end piece.
12. Using the brush (8 or 9), clean the injector seat surface (D).
13. Keep the sealing plugs in position and vacuum clean the injector shaft again.
14. Screw the mounting rod (6) into the sealing plug (7) and pull out the sealing plug.
15. The last step is to clean the injector nozzle port (B).
16. Apply a small amount of grease to the bottom end of the wire brush (1). By apply the grease, dirt and
combustion residues will be retained and the anti-clockwise rotating movement transports these
deposits upwards and removes them from the combustion chamber.
17. Carefully insert into the nozzle opening and clean it by rotating the wire brush anti-clockwise several
times.
18. When removing the brush (1), keep rotating the wire brush anti-clockwise.
19. Before mounting the new injectors, do not forget to insert a new copper seal.
