Notes:

• ◆ Note the 'use-by' date of the sealant.
• ◆ Sump and sump tray must be installed within 5 minutes of applying silicone sealing compound.
• ◆ Sump can be offered up easier and with greater security if, for guide purposes, M6 studs are inserted into the cylinder block flange at two positions.

• ‒ Apply silicone sealing compound, as shown, to clean sump sealing surface. Sealing compound bead must be.
• ‒ 2...3 mm thick.

Note:

The sealing compound bead must not be thicker, otherwise excessive sealing compound will enter the sump and may block the oil suction pipe strainer.

• ‒ Install sump immediately and tighten all sump bolts lightly.
• ‒ Tighten new sump bolts to
      10 Nm.
• ‒ Then tighten all bolts a 1/4 turn (90 °) further.
• ‒ Tighten sump/gearbox bolts to 40 Nm.

• ‒ → Apply silicone sealing compound, as shown, to clean sump tray sealing surface. Sealing compound bead must be:
• ‒ 2...3 mm thick.
• ‒ and run on inside of bolt holes -arrows-.

The sealing compound bead must not be thicker, otherwise excessive sealing compound will enter the sump and may block the oil suction pipe strainer.

• ‒ Install sump tray immediately and tighten all bolts lightly.
• ‒ Then tighten bolts to
      15 Nm.

Note:
