Mercedes C-Class

1. Uncover a spherical support of the coupling device.
2. Take out a spherical support from the car.

3. Check visually spherical head (1) and a support (2). At pollution of a support clear it by means of a vapor jet and dry air. Clear a spherical head water and a brush and wipe with a dry rag.  It is not necessary to apply to cleaning of a spherical head steam or any solvent, such as, gasoline.

4. Measure diameter of a sphere of a connecting element (3). If diameter less than 39 mm, replace a spherical head.

1. Visually check existence of mechanical damages of a spherical head.
2. Pull the handle and turn it in situation "rot" ("red") so that the handle was fixed.
3. Insert a spherical head vertically into a support so that it was automatically recorded.

The green tag of the handle has to be closed by a white tag on a spherical head.

4. Close the handle then it should not have an opportunity to move outside.

1. Oil the lock for transmissions, motive oil or universal lubricant.
2. Oil pure motive an axis of the handle (4) between a spherical head and the handle, and also an axis of descent (5).
3. Slightly grease with jellied lubricant the following parts on a spherical head:

· A guide with a sphere 6;
· Surface of descent 7;
· The directing surface 8.

4. Grease with a thin layer of jellied lubricant a support (2) in the places noted by shooters.
