E39 series BMW 5

1. Before the beginning of work let's to the car pass some kilometers to warm up lubricant liquid of differential, then поддомкратьте the car and reliably establish it on support.
2 Place drain capacity, rags, newspapers and a face key under the car. As lubricant liquid will hot, put on rubber gloves to prevent burns.
3 Remove a stopper of a bulk mouth from differential; it is top of two jams.

2. Turn out a stopper of a jellied mouth (1) face key. Address to an accompanying illustration.
5. If a small amount of oil, level normal pours out and RKPP is tight. Otherwise check a finger, whether oil level reaches the bottom edge.

At considerable leakages of oil it is necessary to establish the reason and to eliminate it.

Having established capacity under differential, weaken a drain stopper (2); it is bottom of two jams.

3. Carefully turn on a drain stopper, yet will not remove it from a casing.
7 Let's to all liquid flow down in drain capacity. The drain stopper is magnetized and draws to itself metal shaving. Wipe shaving from a stopper. Wrap a stopper with a new sealing ring the moment of 50 Nanometers.
8 становите a drain stopper and reliably tighten it.
9 Fill differential with lubricant liquid.

RKPP oil rather dense. Therefore do not fill in at once a lot of oil. Make a break and substitute capacity for collecting the poured oil.

10 Establish a bulk stopper with a new sealing ring and reliably tighten it the moment of 50 Nanometers.
11 Lower the car on the earth. Having passed the first some kilometers, check, whether the drain stopper proceeds.
