7.13.2 Exhaust flaps – Checking coupling rods operability and play

Preconditions

☑

Engine is stopped and starting disabled.

☑

Operating voltage is not applied.

WARNING

Exhaust flaps / air flaps close rapidly.

Risk of crushing!

• Using a suitable tool, check exhaust flaps / air flaps by pressing the actuating linkage to its limit

several times and releasing it.

WARNING

Component is hot.

Risk of burns!

• Wear protective goggles.

Checking coupling rods (bypass and EGR flap) – mechanically

Note:

For installation position of exhaust flaps, refer to overview (→ Page 154).

Remove guard plates of exhaust flaps.

Check operability and ease of movement of
coupling rod (1) by moving it at the speci-
fied points (arrows) and make sure that
there is no excessive play.

Result:

Replace coupling rod (1) if it is jamming,
sluggish or features excessive play
(→ Page 158).

Check whether the internal spring pulls the
flap into the F-position:
• Fail-safe position for bypass flap and

EGR shutoff flap: opened.

• Fail-safe position for donor cylinder flap:

closed.

Result:

If the bypass flap/EGR shutoff flap is
closed or the donor cylinder flap is open,
contact Service.

Checking coupling rod (donor cylinder flap) – mechanically

Note:

For installation position of exhaust flaps, refer to overview (→ Page 154).

Remove guard plates of exhaust flaps.
