The prevention

On petrol engines V6 and diesel engines С223 demountable bearings of a camshaft are provided. On engines of other updatings which are considered in the given management, camshaft support are cast at the same time with a head of cylinders.

Removal and installation

Removal and installation of bearings of a camshaft of engine V6 by means of a special stripper


Combination of lubricant apertures of bearings of a camshaft by means of a piece of the wire bent at an angle 90


Camshaft bearings are replaced at partial or full dismantling of the engine.

1. For performance of procedure the engine is recommended to be removed from the car.
2. It is necessary to remove a camshaft, pushers, a flywheel and broad заглушку (is in a forward part of the engine). Заглушка выпрессовывается from within the block of cylinders.
3. To replace bearings of a camshaft without full dismantling, it is necessary to remove a camshaft and a cranked shaft, pistons in gathering with rods remain on a place.
4. Before removing a cranked shaft, put on bolts шатунных covers pieces of rubber hoses not to damage a neck of a cranked shaft.
5. That rods did not interfere with replacement of bearings of a camshaft rods it is necessary to attach to a lateral part of the block of cylinders. For this purpose attach their rubber rings to the bolts of the oil pallet screwed in the block of cylinders.
6. At strong deterioration of bearings, or at major repairs of the engine bearings vary as follows.
7. Выпрессуйте заглушку from the block of cylinders.
8. Establish a stripper, having rested a teeth against the replaced bearing.
9. Gradually wrapping a stripper nut, take the bearing.
10. Выпрессуйте other bearings, forward and back bearings act in film in last turn.
11. For removal of forward and back bearings turn a stripper and выпрессуйте each of bearings in the block of cylinders.
12. Without changing stripper position запрессуйте new bearings.
13. Again turn a stripper, establish in a place and запрессуйте other bearings.
14. Запрессуйте new заглушку.
15. Be convinced that lubricant apertures (1) have coincided with lubricant channels.

Condition check

1. Wash out a camshaft in solvent and examine a condition of cams and basic necks.
2. At a doubtful condition of cams measure them in longitudinal () and cross-section () directions.
3. At considerable deterioration of cams or basic necks the camshaft follows прошлифовать or to replace.

The prevention

If basic necks are worn out, bearings also are worn out and are subject to replacement.

4. If cams and basic necks have no wear tracks check up palpation of a camshaft by means of prisms and стрелочного the indicator. If palpation in the centre exceeds 0,025 mm a camshaft replace.
5. Measure diameters of cams in two mutually perpendicular directions. From diameter of the clown subtract diameter in a perpendicular direction (define cam lifting). If this difference for cams of final and inlet valves differs, the camshaft follows прошлифовать or to replace.
