2 How can an 8V6 Audi be aligned without special tools?

1. Keep the piston of the first cylinder at the top dead center position, the notch on the outer edge of the crankshaft timing pulley and the bulge on the pulley chamberTag alignment.

2. Ensure that the pulley chamber and each transmission pulley are clean and free of oil and water, and wipe them with a clean white cloth if necessary.

3. Use a special tool to fix the timing pulley of the fuel injection pump and tighten the nut according to the specified torque. Assemble the belt transition wheel assembly, and tighten the hexagonal flange face positioning bolt connecting the belt transition wheel assembly to the specified 110 10N·m.

4. Use the M8 process positioning bolt to position the camshaft timing pulley and the fuel injection pump timing pulley at the corresponding threaded hole position in the pulley chamber; The pulleys have been marked with assembly marks, and the assembly line assembly has been changed to assembly by marking.

5. The timing belt assembly is required to be inserted into each transmission pulley in turn according to the diagram sequence (i.e., 1 crankshaft timing pulley - 2 camshaft timing pulley - 3 belt transition wheel - 4 fuel injection pump timing pulley), and the mark on the belt is required to be aligned with the mark on each pulley, as shown in the figure. The timing arrow of the belt is the same as the engine running direction (clockwise), and the outer edge of the belt is flush with the outer edge of the camshaft (ensure that the distance between the outer edge of the belt and the outer edge of the camshaft pulley is 0, and ensure that the end face of the belt is in the same plane.)

After aligning the crankshaft, pull the wire in the parallel camshaft

Straighten it with cotton thread and you can do it at four points and one line.

The specific operation steps for Audi engine timing are as follows:

1. Insert the special tool for the Audi A6 crankshaft, turn the Audi A6 crankshaft clockwise, and when it is stuck, it is the top dead center of the 1st cylinder.

2. Install special tools on the rear of the Audi A6 camshaft to fix the position of the Audi A6 camshaft.

3. Use special tools to fix the gear timing of the Audi A6 variable camshaft.

4. Install the Audi A6 timing belt in the direction of the arrow.

5. Ensure that the Audi A6 crankshaft side belt is in place and tighten the Audi A6 timing belt tensioner, and the alignment is completed.

Audi engine timing diagram: 4 refers to 4 cylinders, 65 is the diameter of each cylinder 65mm. This name is generally the regular model name of the engine, but in common cases, gasoline engines are often called by displacement, such as the so-called, and the like, which is the sum of all cylinder volumes.

Audi timing diagram precautions: if the ignition is too late, the piston reaches the top dead center before ignition, then the piston goes down when the mixture is burned, that is, the combustion is carried out when the volume increases, so that the pressure in the cylinder decreases, the engine power decreases, and at the same time, due to the increase in the contact area between the hot gas and the cylinder wall, the heat loss increases, resulting in overheating of the engine and the increase of fuel consumption.

Rotate the crankshaft, align the groove on the crankshaft pulley with the notch on the cylinder block, and screw the crankshaft positioning pin in to fix the crankshaft. Attach the camshaft positioning tool, clamp the camshaft, and attach the camshaft sprocket. Attention should be paid to the installation of the intake camshaft sprocket, the green mark on the camshaft sprocket is facing upwards, and it is in a straight line with the intake camshaft.

Install the timing chain, use a slotted wire cutter to warp the chain tensioner, simulate the oil pressure, let the tensioner be in a pre-tensioned state, and then tighten the camshaft tensioner.

If the crankshaft sprocket needs to be replaced, the sprocket should be removed with a puller. When installing a new sprocket, the chain and the chain groove should be aligned to prevent loosening. Install the timing chain on the camshaft sprocket next to the celery, fix the sprocket, make the chain hang, and align the timing mark on the camshaft and crankshaft sprocket.

The alignment pin hole on the sprocket and the dowel pin hole on the camshaft are completed, and then the sprocket is installed on the camshaft. The camshaft sprocket bolt tightening torque is 20 N·m. Lubricate timing sprockets and chains with oil.

Turn the crankshaft twice and check that the engine timing marks are aligned.

There are a lot of engines are not pointed, manually carve or draw a point, gear and cylinder block one by one correspondence, gear to find a comfortable position to get the point, the corresponding cylinder block below also get one, 2 biting gears bite each other to get a point. When loading, a pair of a few points, not afraid of making mistakes. I'm really afraid that if I don't get it right, I will take a picture with my mobile phone after the drawing, and I won't be wrong.

Rotate the crankshaft, align the groove on the crankshaft pulley with the notch on the cylinder block, and twist the stool pin into the crankshaft positioning pin to fix the crankshaft. Install the camshaft positioning tool, clamp the camshaft, install the camshaft sprocket. Pay attention to the installation of the intake camshaft sprockets.

The green markings on the camshaft sprockets are facing upwards and are in a straight line with the intake camshaft. Install the timing chain, tighten the chain tensioner with a slotted spiral slag cutter, simulate the oil pressure, make the tensioner in a preloaded state, and then tighten the camshaft screws.

If it is necessary to replace the crankshaft sprocket, remove the sprocket with a pull tool. When installing a new sprocket, align the chain with the chain groove to prevent it from loosening. Install the timing chain on the camshaft sprocket, fix the sprocket, make the chain beam sag, and align the timing marks on the camshaft and crankshaft sprocket.

Align the dowel pin hole on the sprocket with the dowel pin hole on the camshaft, and then install the sprocket to the camshaft. The tightening torque of the camshaft sprocket bolt is 20 N·m. Lubricate timing sprockets and chains with oil.

Turn the crankshaft twice to check that the engine timing marks are aligned.

It doesn't make sense to have a lot of engines. Carved or painted by hand a point, the gears correspond to the cylinder block one by one. Once you have found the comfortable position of the gears, make one for the cylinder block below and make a point for the meshing part of the two meshing gears.

When installing, mention a few points, and don't be afraid of making mistakes. I'm afraid I can't really do it. Take a picture with your phone when you're done, and you won't go wrong anyway.

Millions of car purchase subsidies.

Tools Required: Wrench.

1. First use the roulette card to jam the timing wheel, and then you can adjust the timing chain pants. Xinzhi.

2. After that, open the top of the disc on the timing wheel to facilitate the adjustment of the timing chain.

3. After that, find the colored chain teeth on the camshaft, which is used for proofreading.

4. After that, align the colored teeth of the timing chain with the small dots on the roulette wheel, so that the timing is calibrated.

5. After that, use a wrench to fix the timing wheel screws, so that the proofreading is completed.
