General Information: Components
Rear Final Drive
- Allocate bolts and other components according to final drive code.
- When installing, check the oil level in the rear final drive and fill if necessary. Refer to REAR FINAL DRIVE GEAR OIL, CHECKING .
- Capacities and specifications, refer to SPECIFICATIONS .
- Clean the contact surfaces when installing the brackets as well as any waxed components. Contact surfaces must be free of grease and wax.
- Always clean the connection locations and the area around them before loosening.
Oil, Environmental and Disposal Regulations
- Handle ATF, transmission fluid and other oils with care.
- Dispose of drained ATF properly.
- Follow the legal environmental and disposal regulations.
- Follow the information provided on oil packaging.
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 .
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.
