Repair instructions

Aftercooler and heat exchanger,

disassembly

Remove the end panels on the heat exchanger or

aftercooler (6 mm socket cap).

Remove the O-rings and intermediate rings.

Unscrew the plugs (1) over the two guide balls for the

aftercooler insert a few turns (10 mm socket cap).

Press the inserts out.

Note: The inserts can only be pressed out backwards

since they have a flange at the rear.

Aftercooler and heat exchanger, cleaning

Flush and clean the inserts, both internally and

externally. Use suitable brushes.

Also clean the housing.

Note. Be careful to avoid getting any contamination

into the inlet manifold of the engine via the aftercooler.

Check that the drain hole (1) at the rear of the

aftercooler is not blocked.

Aftercooler and heat exchanger,

assembly

Install the inserts in the housing. Use new seal rings.

Note. The intermediate rings should be installed with

the hole downwards. Inserts and intermediate rings

can only be installed in one position because of the

hole spacing.

Install the end lid with new sear rings. Tighten plugs

(1) on the aftercooler.
