| | Before installation of camshafts turn a bent shaft approximately on 30 ° against the direction of rotation of the engine (to the left for a pulley hexagon) through VMT. Thus, any of pistons will not stand above and it will be possible to put valves into place. Hydropushers of valves without loading from the camshaft are extended and after installation demand some time again to contract. Thereof valves can be open more, than it corresponds to position of the camshaft and can get on pistons. Therefore after installation of camshafts it is necessary to wait 40 min. until it is possible to turn the engine. Only after that it is possible to turn a bent shaft in the provision of VMT and to establish GRM drive chains, address the subsection Installation of a Head of Cylinders. |
|
1 Check a surface of pushers, with defects replace. aspredelitelny shaft also install camshafts so that tops of cams of the first cylinder showed at each other. |
|
2 Establish a level with bearings and the inserted pushers in a head of cylinders. Check existence of the centering plugs-3-. | 3 Insert inserts of bearings according to marking. They have to be at former places. 4 Insert the device and clamp inserts. 5 Tighten inserts of camshafts the moment of 15 N • m. 6 Remove adaptation.
|
7 Insert a ruler for fixing of camshafts. |
|
8 If necessary. An arrow - a hexagon of the second camshaft. |
| | You watch to damaging the case of camshafts. If necessary to a soshlifuyta outside wrench. | 9 Fix a wheel of the sensor and a persistent washer on the camshaft of inlet valves by the moment of 20 N • m.
|
10 Establish an asterisk on distributive to a shaft of final valves. The arrow on an asterisk has to specify towards the top edge of a head of cylinders. |
|
11 The piston of a natyazhitel of a chain-1-is turned out. Screw in a carving of a natyazhitel the BMW tool – 11 4 220. |
| | The specified tool presses a chain and pulls a little it that asterisks of camshafts were in the working family way. With some skills such tool can be manufactured independently. In the absence of the tool the correct installation of a chain is impossible. | 12 Slightly press a natyazhitel of a chain rotation of the tension screw of the BMW tool – 11 4 220. The chain should not sag.
|
13 Expose an asterisk on the camshaft of final valves. The arrow on an asterisk has to specify in the parties of the top edge of a head of cylinders. |
14 Fix an asterisk on distributive to a shaft of final valves by three bolts the moment of 28 N • m.
| 15 Fix the top natyazhitel of a chain. |
|
16 Insert the gear plug-6-. At the same time hollows of teeths on distributive to a shaft and the gear plug have to be opposite to each other (an arrow on an illustration). |
|
17 Insert a gear shaft so that bolts of fastening of an asterisk lay in the center of oval openings of the gear plug. | 18 Put on the top chain asterisks and expose according to the markings put at removal. If new details are established, transfer to them markings from old details.
|
19 Put on the top chain with both asterisks camshafts. At the same time hollows of teeths (the shooter on an illustration) on distributive to a shaft of inlet valves and on an asterisk have to be opposite to each other. Insert a gear shaft-4 pins into hollows of teeths and press. |
| | Unlike an illustration the persistent washer-5-is not established yet. | 20 Again take out a gear shaft-4-a little so that 1 mm of width of tooth was visible. 21 Establish a persistent washer on an asterisk of the camshaft of inlet valves so that it was possible to read the inscription "FRONT". Screw nuts of fastening of an asterisk so that they prilgat, but do not tighten them. 22 Fix an asterisk of camshafts, having tightened nuts the moment of 5 N • m, and then again weaken them half way. 23 Establish a persistent washer on an asterisk of the camshaft of inlet valves so that the inscription "F" was visible. If the inscription is not visible, pay attention to the direction of installation of a persistent washer: Big adjacent diameter has to show in the direction of the camshaft. 24 Establish a sensor wheel on an asterisk of the camshaft of final valves. The arrow on a wheel has to be turned outside towards the top edge of a head of cylinders. 25 Take out against the stop a gear shaft on an asterisk of the camshaft of final valves.
|
26 Press a hand on a natyazhitel of the top chain and remove the fixing BMW tool. |
|
27 Pull a chain rotation of the tension screw of the BMW-11 4 220 tool the moment of 0.7 N • m. |
|
28 Clear the sealing surface of the VANOS block of oil and pollution. Check existence of the directing plugs-1-. |
|
29 Fix the BMW-11 6 150 tool - 1-(shooters on an illustration). This tool fixes gear plugs at a tension of asterisks. | 30 Press three nuts-2-and-3-to both asterisks at first the moment of 5 N • m, without tightening them. 31 Tighten bolts-4-in grooves the moment of 22 N • m. 32 Tighten nuts-2-and-3 moment of 22 N • m. 33 Disconnect the BMW-11 6 150 tool. 34 Condense corners of a sealing surface between a head of cylinders and the VANOS block Drei Bond 1209 or Loctite Ultra Black sealant.
|
35 Replace sealing laying of the VANOS block. Fix the block (arrows on an illustration). Tighten M6 nuts the moment of 10 N • m and nuts of M6 the moment of 22 N • m. |
36 Join the socket at the VANOS block. 37 Screw the directing bolts at camshafts of inlet and final valves and tighten the moment 10 N • m.
| | The left carving, that is for a wraparound it is necessary to rotate to the left. | 38 Replace the covers which are under carving traffic jams and insert them flat-nose pliers. 39 Wrap carving traffic jams with new sealing rings at camshafts an admission of inlet and final valves and tighten the moment 50 N • m. 40 Fix by bolts an engine eye in front. 41 Remove the special tool for fixing of distributive and cranked shaft.
|
42 Attach the pipeline of compressed air by means of an adapter and give air pressure of 2 - 8 bars. | 43 Turn not less than on two turns a bent shaft in the direction of an hour hand and the VANOS block loaded with air.
|
44 Install the engine in the provision of VMT of the first cylinder. Tops of cams of inlet and final valves of the first cylinder (an arrow on an illustration) have to be turned up at the same time. |
|
45 Again insert a core for fixing of a bent shaft. | |
