1

Saw the pressure line (1) close to the tube nut (4).

2

Loosen the tube nut (2) and rotate the pressure line (1) to the side.

3

Drill straightly the pressure line (3), deep enough so that the tube nut (4) can be removed and the repair adapter (5) can be used up to its collar.

 Pay attention that neither grease nor shavings reach the exhaust gas aftertreatment unit.
This could cause malfunctions.

 Cover the drill with grease, so that the shavings remain adhered to it and do not fall on the exhaust gas aftertreatment unit. Use different drills, one after other, with increasing diameters. Beginning with Ø 10 mm up to approx. Ø 14.5 mm. Beginning in steps of 1 mm - then, of 0.5 mm.

4

Clean the connector of the pressure line (3).

5

Position the adapter of repairs (5) in the connector of the pressure line (3), as shown in the figure.

 The adapter of repairs (5) should be positioned with the collar on the connector of the pressure line (3) .

6

Weld the adapter of repairs (5) in the connector of the pressure line (3), gas-proof.

7

Cover the tube nut (7) with a thin layer of high temperature grease.

8

Insert the new pressure line (6) with the cutting ring (8) and the tube nut (7) in the adapter of repairs (5).

9

Slightly tighten the tube nut (7).

 The new pressure line (6) should still be able to be rotated.

10

Align the remaining pressure line (1) with the new pressure line (6).

11

Adjust the length of the new pressure line (6) and the remaining pressure line (1).

 There are different variants depending on the exhaust gas aftertreatment unit. For this reason, if necessary, the pressure lines (6) and (1) should have their length adjusted. In work step below should be necessary to cover as little as possible with the piece of hose (9). If necessary, the pressure lines (6) and (1) should be a few straightened.

12

Connect both pressure lines (1, 6) with the piece of hose (9) and the hose clamps (10).

 There must ensure that the piece of hose (9) get not bent.
Otherwise, this will result in malfunctions.

 Shorten the piece of hose (9) so that the pressure lines (1, 6) entering about 3 cm in each tip of the piece of hose (9).
