Components

Rear Final Drive
^ When replacing rear final drive, check and if necessary, correct oil level in final drive.

^ Clean contact surfaces when repairing mounting brackets and waxed components. Contact surfaces must be completely free of oil and grease.

^ Thoroughly clean all connections and surrounding area before disconnecting.

O-rings, gaskets, seals
^ Always replace O-rings, gaskets and seals.

^ After removing gaskets and seals, always inspect the contact surfaces at housing or shaft for burrs resulting from removal, or for other signs of damage.

^ Thoroughly clean housing joint surfaces before assembling.





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

^ The open side of the gaskets points toward the fluid to be sealed in.

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

^ Check transmission oil level after replacing gaskets and seals

Securing rings
^ Do not over-stretch circlips.

^ Always replace damaged or over-stretched circlips.

^ Securing rings must be fully seated in groove.





^ Replace roll pins. Installation position: Slot - A - is longitudinal to line of force - arrow -.

Nuts, bolts
^ Loosen and tighten bolts or nuts for securing covers and housings in diagonal sequence.

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

^ The tightening torques stated apply to non-oiled nuts and bolts.

^ 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. Then insert bolts with locking fluid AMV 185 101 A1.

^ Threaded bores into which self-locking bolts or bolts with locking compound were threaded in, must be cleaned (e.g. using threaded tap). Otherwise there is the danger that the bolts may shear when removed again.
