- After replacing any of the shaft seals, check the gear oil level (Refer to GEAR OIL, CHECKING LEVEL ) or the ATF level in the final drive (Refer to ATF LEVEL, CHECKING, 0BE, 0BF ).
Shaft Seal for the Flange/Driveshaft
- Fill the space between the sealing lips -arrow- half way with Sealing Grease G 052 128 A1.
Flange Shaft Seals
- Coat the space between the sealing lips -arrow- with ATF.
O-rings, Gaskets and Seals
- O-rings, gaskets 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.
- Lightly lubricate O-rings before installing to prevent them from being crushed when inserting.
- After replacing any of the gaskets, seal and O-rings, check the gear oil level (Refer to GEAR OIL, CHECKING LEVEL ) or the ATF level in the final drive (Refer to ATF LEVEL, CHECKING, 0BE, 0BF ).
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: the slit -A- should align 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 with self-locking bolts or bolts coated with locking fluid must be cleaned, for example using a thread tap. Otherwise there is a risk that the bolts will shear the next time they are removed.
