Check, cleaning and greasing of the coupling device

Cleaning and check


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. A spherical head clear water and a brush and wipe a dry rag.

 It is not necessary to apply to cleaning of a spherical head of pairs 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.

Work check


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

 The green label of the handle should be closed by a white label on a spherical head.

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


4 — a handle Axis
5 — a descent Axis
6 — Directing with a sphere
7 — a descent Surface
8 — the Directing surface


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

· Directing with a sphere 6;
· Surface of descent 7;
· Directing surface 8.

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