Removal and camshaft installation

Models 520i, 523i, 528i

Work on removal and installations of a camshaft demands use of the special tool. It is recommended to lead it in the conditions of specialized repair trucks of BMW firm. Here camshaft removal on the removed head of cylinders is described. The specified operation can be executed and on the established head of cylinders. Thus 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 should correspond presented in Specifications.

 REMOVAL

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

2. Turn out hairpins. Address to an accompanying illustration.

3. Removal of camshafts needs the BMW 113260 adaptation. The adaptation holds bearings of camshafts in working situation at removal of loose leaves. Removal of both camshafts is carried out equally. The sequence has no value. Address to an accompanying illustration.

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

6. Turn of an ekstsentrikovy shaft of the adaptation fix covers of bearings. Address to an accompanying illustration.

7. Unscrew all bolts of fastening of covers of bearings.

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

8. Remove the adaptation.

9. Remove covers of bearings and a camshaft. Lay covers one after another. At assembly they should be established in former provisions. Covers of bearings of a camshaft of final valves have marking with А1 on А7, inlet valves with Е1 on Е7. Address to 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. Watch aligning plugs (3). Levels in a point (4) have marking "And" for final valves and the marking “Е” for inlet valves. Address to an accompanying illustration.

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


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

Installation

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

If the camshaft acted in film on the established head of cylinders, turn a cranked shaft approximately on 30 ° in the direction of rotation of the engine through VMT. Thus in VMT there will be no piston and valves do not rest against them. Establish camshafts and check the distribution moments. Only after that a cranked shaft turn back in VMT and put on a chain, address to the Section Removal and installation of a head of cylinders.

 INSTALLATION

1. Check pushers on wear existence (задиров), if necessary replace with the 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 to an accompanying illustration.

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

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

Model 525tds

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

 REMOVAL

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

2. Removal of camshafts needs the BMW 113260 adaptation. The adaptation holds bearings of camshafts in working situation at removal of loose leaves. Establish the adaptation and fix it bolts of fastening of a cover of a head of cylinders. Address to an accompanying illustration.

3. Turn of an ekstsentrikovy shaft of the adaptation fix covers of bearings.
4. Unscrew all bolts of fastening of covers of bearings.
5. Remove the adaptation.
6. Remove covers of the bearing and a 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. To fixing of pushers HUNDRED applies suckers which are established from above on pushers and interfere thus with their loss. To be established pushers should on former places. Address to an accompanying illustration.


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

 INSTALLATION

1. Check pushers on wear existence (задиров), if necessary replace with the 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 loose leaves of bearings according to markings. They should be established on former places.
4. Establish the adaptation and clamp loose leaves.
5. Loose leaves evenly cross-wise tighten the moment of 15 Nanometers.
6. Unclench the adaptation and remove it. Screw spark plugs.
7. Establish a head of cylinders, address to the Section Removal and installation of a head of cylinders.
