Removing oil suction pump

Removing oil suction pump - cylinder bank 4-6

Caution
Risk of damage due to particles of dirt.
Danger of material damage due to blocked oil bores/oil ducts.

- Absolute cleanliness is essential when working on the engine.
- Lay removed engine parts on a clean base and make sure to cover them.
- Use the cover for dust protection when fitting the engine NR.165 on the engine assembly support.

1. Remove oil return line on the pump neck.
1.1. Loosen union nut (a/f 27) and counter at the pump neck at the same time with an open-ended wrench (a/f 24).
1.2. Collect emerging engine oil in a suitable container.
1.3. Turbo only: Unscrew M6 Torx screw on the holding clamp securing the oil line to the pump.
