Component Description

To perform a problem-free and successful transmission repair, extreme caution and cleanliness, as well as properly functioning tools are an important requirement. Understandably, general safety guidelines apply when performing repairs.

Rear Final Drive

• For the correct bolts and other components according to the final drive code, refer to the electronic parts catalog ETKA.

• When replacing the rear final drive, check and if necessary, correct oil level in final drive. Refer to => [ Rear Final Drive Gear Oil, Checking ] Rear Final Drive 0BD (0B2A,0B6A,0B4A,0B5A,0BKA Transmission).

• Capacities and specifications, refer to => [ Engine Code, Transmission Allocation, Ratios and Capacities ] Engine Code, Transmission Allocation, Ratios and Capacities.

• Clean the contact surfaces before installing the brackets and waxed components. Contact surfaces must be free of wax and grease.

• Thoroughly clean all connections and the surrounding area before disconnecting.

Oil, Environment and Disposal Regulations

• Be very careful when handling transmission fluid and other fluids.

• Dispose of the drained fluids properly.

• Follow all environment and disposal regulations.

• Be sure to read the instructions on the fluid containers.

O-rings, Seals and Gaskets

• Always replace the O-rings, seals and gaskets.

• Check the contact surfaces on the housing and shaft for burrs and damage after removing the seals.

• Thoroughly clean the separating surfaces on the housing before assembling.

• Before installing, lightly oil the outer circumference of shaft seals and fill gap between sealing lips - arrow - half way with sealing grease (G 052 128 A1).





• The open side on the shaft seals faces the fluid to be sealed off.

• Lightly lubricate O-rings before installing, this prevents the rings from being pinched when inserting.

• Check the final drive oil level after replacing any seals or gaskets. Refer to => [ Rear Final Drive Gear Oil, Checking ] Rear Final Drive 0BD (0B2A,0B6A,0B4A,0B5A,0BKA Transmission).

Circlips

• Do not stretch the circlips.

• Always replace damaged or stretched circlips.

• The circlips must touch the bottom of the groove.

• Replace the adapter sleeves. Installation position: Slot - A - is longitudinal to line of force - arrow -.





Bolts and Nuts

• Loosen and tighten the bolts and nuts of covers and housings in a diagonal sequence.

• Do not cant, rather loosen and tighten especially sensitive parts in diagonal manner in stages.

• Torque specifications for unoiled bolts and nuts are given.

• Always replace self-locking nuts and bolts.

• Using a wire brush, clean threads of bolts (replace outer driveshaft bolts) which are secured with locking compound. Install the bolts with locking fluid (AMV 185 101 A1).

• If self-locking bolts were installed or if regular bolts were installed with locking fluid, then the threaded holes must be cleaned with a thread cutter. If the holes are not cleaned, then the bolts could break off the next time they are removed.
