O-rings, Shaft Seals, Seals
- O-rings, shaft seals and seals must be replaced.

- Thoroughly clean housing joint surfaces before assembling.
- Before installing the shaft seals, lightly oil the outer circumference and fill the space between the sealing lips -arrow- halfway with grease G 052 128 A1.
- The open side of the shaft seals point toward the fluid to be sealed in.
- Lightly lubricate O-rings before installing to prevent them from being crushed when inserting.

Bolts and Nuts
- Always loosen or tighten bolts and nuts on covers and housings diagonally.
- Parts which are particularly sensitive to distortion must be kept straight when removing and installing; loosen or tighten diagonally in stages.
- The tightening specifications stated apply to non-oiled nuts and bolts.
- Always replace self-locking nuts and bolts.
- Clean threads of bolts that were applied with locking fluid using a wire brush (does not apply to driveshaft bolts: these must be replaced). Next, use locking compound AMV 185 101 A1 to install the bolts.
- Threaded holes into which self-locking bolts or bolts coated with locking fluid are screwed, must be cleaned (for example tap). Otherwise there is a risk that the bolts will shear the next time they are removed.
