Repair of auto electrician. Technical consumption. Replacing the timing belt on Diesel engines BKC, BMP and them like when the replacement becomes needed

The list of regulated operations that must be performed for the efficient operation of the vehicle includes the replacement of the timing belt of the gas distribution mechanism. This operation will be performed on any car service, but if you want to save, it is better to master it yourself. The article presents a step-by-step instruction, how the timing belt is replaced on the Volkswagen Passat B3 and B5, and the photo gallery and the corresponding video is attached.

When is it time to change?

Replacing the timing belt on the Volkswagen Passat B5 and B3 is performed according to the recommendations specified in the manual, through 60,000 - 90,000 km of run. But at the same time, it should be regularly monitoring its condition, as the belt break is possible. It may have severe consequences in the form of a bent valves and spoiled pistons, since when the breakage, they meet and damage to each other.

The strap of the gas distribution mechanism has the type of rubber rim with the inner surface in the form of teeth serving for better clutch. The decision on the need to replace the belt is accepted after visual inspection. The product is subject to mandatory replacement if the following defects are revealed:

• cracks and scuffs on the surface;
• the teeth are erased, are inwhams, have traces of wear;
• the sidewalls are clouded;
• the material is separated;
• there are oil traces on both surfaces.

When inspection, attention should be paid to other RAC items, when identifying any shortcomings, they need to be changed. Together with the timing belt, it is desirable to change the tensioner.

Replacement process

Before changing the belt of the gas distribution mechanism on the Volkswagen Passat B5, B6 and B3, it is necessary to prepare a place to work. It is more convenient to replace on the observation ditch. The car needs to be installed on the handbrake.

Required tools

To work it is necessary to prepare the following tools:

Stages

1. It turns off the power of the car by disconnecting the negative terminal.
2. Next is dismantled by the air cleaner.
3. Having raised the front of the car by the jack, you need to remove the right front wheel and restor.
4. Then you need to remove the belts of the air conditioner and the generator. On the removed products you need to put the directions for which they rotated to establish similarly when installing.
5. Taking the tensioner as much as possible with the help of a cape, you should weaken the tension. Then you need to insert the rod into the combined holes of the stretch and support rollers and remove.
6. Next, we define two latches remove the upper part of the timing of the timing of timing.
7. Then you need to put all the tags correctly. To do this, it is necessary to turn the crankshaft crankshaft mounting bolt along the clockwise movement, until the labels on the crankshaft pulleys and the timing cover, the grinding gear and the crankshaft pulley, on the head of the cylinder block and camshaft pulley, as well as on the handwheel of the crankshaft and the case.

   Combining tag on flywheel

8. Next is removed the crankshaft pulley.
9. Turning the tensioner counterclockwise and weakening the fastening nut, remove. After that, the crankshaft and camshaft cannot be wrapped in order not to knock the labels.
10. Now you can change the tension roller.
11. The new consumility is set sequentially on the pulleys first crankshaft, then rushed and last on the pulley of the camshaft. After installation, tension is tension using the tensioning roller and tags are checked for a coincidence.
12. When the belt is installed, the assembly is carried out in the reverse order.

    Details of the gas distribution mechanism

It is important that the tags are correctly installed, otherwise, when you turn on the engine, you can brine valve.

After final assembly, you need to check the engine operation. The replacement on the Passat B6 is carried out similar to B5.

and (or)
The engine does not start.
and (or)
In a combination of instruments, Check Engine lamp is burning.

Conclusion station:

One or more faults declared by the client are reproduced.

The following events are saved in the event control event recorder:
00022 P0016: Row 1, camshaft position sensor -G40 / Crankshaft position sensor -G28, signals inconsistency.
and (or)
00808 P0328 Detonation Sensor 1 -G61, too high signal level.

Solution in the conditions of production:

Application of the optimized tensioner chain chain chain:
Starting with engine numbers:
- CAW_135390.
- CBF_106200.
- CCT_289558.
- CCZ_224768.
- CDA_307430.

Solution in the terms of service:

Checking the timing champ chain / tensioner drive chain chain:

Remove the rubber plug (see ill. 2, red circle) in the bottom cover of the timing chain.
Turn the crankshaft in the direction of its usual rotation to the position of the upper dead point (see Ill.1, green arrows).
Using a mirror on the tensioner of the timing chain chain, calculate the number of locking protrusions on the timing tensioner plunger of the timing chain.

Check which version of the timing chain tensioner is set:
- Old version (see Fig. 3).
- New version (see Fig. 4).

Timing chain tensioner, new version:
If you can see more than 6 and grooves (see Fig. 6, pos. In, 4 grooves shown):
Replace the timing chain.

Checking the timing chain tensioner (new version):

Check the performance of the timing chain tensioner, as indicated below:

Remove the bottom cover of the timing chain

- Check the bottom cover of the timing chain circuit for damage. If the bottom cover is damaged, replace the bottom cover of the timing chain circuit.

- press the timing chain tensioner with hand (see ill. 7, number 2) in the tensioner direction (see Ill. 7, number 1).

a. If the timing chain tensioner plunger can move the arm force inside the chain tensioner:
- The timing chain tensioner is faulty - to act further according to paragraph 1.

b. If the timing tensioner is the timing chain tensioner, even after several attempts with an arm force inside the chain tensioner, it is impossible to move:
- TRP drive chain tensioner normally - to act further according to paragraph 2.

Ill. 7. GRM chain drive in the context
Number 1: timing chain tensioner
Number 2: Tension Tensioner Tensioner Tensioner
Arrow: Direction of pressing on the timing tensioner bar

1. The timing chain tensioner is faulty:

- Remove the GBC
- Check if the collision of valves and pistons occurred:
- If it is not detected on the pistons, valves, camshaft, the damage camshaft or bearings, it is necessary to replace the timing tensioner of the timing chain and the timing chain.
- If there has been the collision of valves and pistons, it is necessary to repair the engine.

2. Tensioner Timing chain chain normally:
- remove the valve cover
- Check the camshaft inlet valves and camshaft bearings for damage.
If damage to the camshaft camshaft and camshaft bearings are detected, it is necessary to replace the GBC
- Replace the engine oil and oil filter

Measure the distance from the left outer edge of the partition -A- to the label -b-on the camshaft of the inlet valves.
Nominal value: 61 ... 64 mm.

If the measured value corresponds to the nominal, measure the distance between the label -B-on the camshaft of the ink valves and the label -c-on the camshaft of the exhaust valve.
Nominal size: 124 ... 126 mm

The shift to one gear tooth leads to a deviation from the nominal value by about 6 mm. If this offset is detected, the chain should be reinstalled.
