• Always clean the connection locations and the area around them before loosening.

Oil, Environmental and Disposal Regulations

• Dispose of drained ATF properly.

• Follow the legal environmental and disposal regulations.

O-rings, Shaft Seals, Seals






• O-rings, shaft seals and seals must be replaced.

• After removing gaskets, examine contact surface on housing/shaft for burr resulting from removal or for other signs of damage.

• 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.

• After replacing the seals and sealing rings, check the transmission fluid level and fill if necessary. Refer to => [ Rear Final Drive Gear Oil, Checking ] Description and Operation.

Fasteners






• Do not overstretch the circlips.

• Always replace damaged or stretched circlips.

• The circlips must fit completely inside the groove.

• Replace the adapter sleeves. Installed position: Slit - A - should be in line with the line of force - arrow -.

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.
