10.3. Check of work and replacement of the elastic coupling

Check

Though experts of BMW do not stipulate concrete intervals of performance of checks of the elastic coupling located between forward section of the driveshaft and transmission, it it is necessary to examine each time when you work under the car. The coupling is made of rubber and consequently it is susceptible to impacts of blows of road gravel on it, heat developed by system of release, and also to driveshaft twisting. Examine the coupling on existence of cracks, the gaps, the dropped-out fragments and deformations. The worn-out or damaged coupling replace.

Replacement

 PERFORMANCE ORDER

  1. Remove the driveshaft (see. Section Removal and driveshaft installation).
  1. Give nuts and bolts of the elastic coupling and remove the coupling from the driveshaft.

It will be easier to establish bolts on the elastic coupling if to fix it motionlessly by means of a hose piece.


  1. Establish the new coupling with NEW самоконтрящимися nuts. If on the coupling marking in the form of arrows is put, they should be directed to flange levers, instead of to heads of bolts. Tighten nuts with demanded effort.
  1. Establish the driveshaft (see. Section Removal and driveshaft installation).
