Removal and installation of the camshaft

Models 520i, 523i, 528i

Work on removal and installations of the camshaft demands use of the special tool. It is recommended to carry out it in the conditions of specialized auto repair shops of BMW. Here removal of the camshaft on the removed head of cylinders is described. The specified operation can be executed also on the established head of cylinders. At the same time it is necessary to carry out preliminary works according to the description in the Section Removal and installation of a head of cylinders.

Measure camshafts. Value of axial and radial gaps has to correspond presented in Specifications.

 REMOVAL

1. Remove a head of cylinders, address the Section Removal and installation of a head of cylinders.

2. Turn out hairpins. Address an accompanying illustration.

3. Removal of camshafts requires BMW 113260 adaptation. Adaptation holds bearings of camshafts in working situation at removal of inserts. Removal of both camshafts is carried out equally. The sequence does not matter. Address an accompanying illustration.

4. Turn out spark plugs.
5. Install adaptation and fix it in carving openings of spark plugs of cylinders 1 and 4 by the moment of 25 Nanometers.

6. Fix by turn of an eccentric shaft of adaptation covers of bearings. Address an accompanying illustration.

7. Turn off all bolts of fastening of covers of bearings.

The cover of the first bearing of the camshaft of inlet valves is aligned by the adjusting plug. For an exception of a perekashivaniye of the camshaft turn off bolts of fastening of the first cover and remove it. Address an accompanying illustration.

8. Remove adaptation.

9. Uncover bearings and the camshaft. Lay covers one after another. At assembly they have to be established in former provisions. Covers of bearings of the camshaft of final valves have marking from A1 on A7, inlet valves from E1 on E7. Address an accompanying illustration.

10. If it is necessary, for example, if it is necessary to remove valves, remove assembled a level of bearings (2) with pushers. You watch the aligning plugs (3). Levels in a point (4) have marking "And" for final valves and the marking "Е" for inlet valves. Address an accompanying illustration.

Pushers drop out of a level of bearings. HUNDRED applies suckers which are established from above on pushers to fixing of pushers and interfere thus with their loss. Mark pushers. They have to be established on former places.


It is impossible to put the removed pushers of valves on a head more than 10 min. Otherwise oil begins to follow from pushers that will lead to failure of automatic compensation of a gap in valves.

Installation

If the camshaft is removed, it must be kept in mind the following. Without loading hydropushers are extended and after installation some time for their compression is required. Thereof valves can be open in the situation which is not corresponding to a cam for some time and to rest against pistons. Therefore it is necessary to maintain the next time between installation of the camshaft and a head of cylinders: at a temperature of +20 °C (room temperature) - 4 min., at a temperature of +10 °C - 11 min. After installation of a head of cylinders it is necessary to wait 30 more min. After that it is possible to start the engine.

If the camshaft was removed on the established head of cylinders, turn a bent shaft approximately on 30 ° in the direction of rotation of the engine through VMT. At the same time in VMT there will be no piston and valves do not rest against them. Install camshafts and check the distribution moments. Only after that turn a bent shaft back in VMT and put on a chain, address the Section Removal and installation of a head of cylinders.

 INSTALLATION

1. Check pushers for existence of wear (zadir), if necessary replace with new.

2. Oil bearings of camshafts and establish shaft so that tops of cams of inlet and final valves of the first cylinder showed at each other. Address an accompanying illustration.

3. Establish a level of bearings with the inserted pushers in a head of cylinders. Do not forget about the aligning plugs (3).

4. Insert inserts of bearings according to markings. They have to be established on former places.
5. Install adaptation and clamp inserts.
6. Tighten inserts the moment of 15 Nanometers.
7. Unclench adaptation and remove it. Screw spark plugs.
8. Establish a head of cylinders, address the Section Removal and installation of a head of cylinders.

Model 525tds

Measure axial and radial gaps of camshafts. The required value is given in Specifications.

 REMOVAL

1. Remove a head of cylinders, address the Section Removal and installation of a head of cylinders.

2. Removal of camshafts requires BMW 113260 adaptation. Adaptation holds bearings of camshafts in working situation at removal of inserts. Install adaptation and fix it by bolts of fastening of a cover of a head of cylinders. Address an accompanying illustration.

3. Fix by turn of an eccentric shaft of adaptation covers of bearings.
4. Turn off all bolts of fastening of covers of bearings.
5. Remove adaptation.
6. Uncover the bearing and the camshaft. Covers have marking with 1 on 7 which is visible from release.

7. If it is necessary to remove, for example, valves, remove pushers. HUNDRED applies suckers which are established from above on pushers to fixing of pushers and interfere thus with their loss. Pushers have to be established on former places. Address an accompanying illustration.


It is impossible to put the removed pushers of valves on a head more than 10 min. Otherwise oil begins to follow from pushers that will lead to failure of automatic compensation of a gap in valves.

 INSTALLATION

1. Check pushers for existence of wear (zadir), if necessary replace with new. Pushers on former places are established.
2. Oil bearings of camshafts and establish shaft so that tops of cams of inlet and final valves of the first cylinder showed upward.
3. Insert inserts of bearings according to markings. They have to be established on former places.
4. Install adaptation and clamp inserts.
5. Inserts evenly cross-wise tighten the moment 15 Nanometers.
6. Unclench adaptation and remove it. Screw spark plugs.
7. Establish a head of cylinders, address the Section Removal and installation of a head of cylinders.
