Replacing the camshaft on a VAZ 2106 may be required for various reasons, but before moving on to this process you need to have an idea of the purpose of this unit. The camshaft is the main timing link and participates in the combustion process of the combustible mixture.

The camshaft is located at the top of the cylinder head. It is connected to a pulley or toothed sprocket of the crankshaft via a belt or chain drive.

If the camshaft fails

The camshaft on the VAZ 2106 model is rarely dismantled. Typically during repair or disassembly. Sometimes to replace it.

Signs

First, let's talk a little about the signs that indicate that the camshaft is faulty, its journals or beds are worn out. It is difficult to determine whether the shaft or something else is knocking in the VAZ 2106 engine, but it is possible. The knock of the camshaft is dull and clearly audible. As engine speed increases, the knocking becomes more frequent.

Some drivers determine knocking in this unit using a stethoscope or a stick through the valve cover. But often it is difficult for an inexperienced driver to do this. Therefore, the best way to diagnose the camshaft is to remove it, wash it and inspect it.

If the camshaft is faulty, the following symptoms may occur:

a dull knock, reminiscent of hammer blows;
it is impossible to adjust the valve clearances; while the crankshaft is turning, the camshaft is constantly in different positions.

This video shows how you can eliminate longitudinal runout of a camshaft.

The most reliable method for diagnosing problems with the VAZ 2106 camshaft is to dismantle it from the car and wash it. You can wash it in gasoline or other cleaning liquid. Next, you need to hold the shaft and hit the bed, when you hear the slightest knock, we determine whether the mechanism is worn out. Be sure to make sure that the shaft does not move in bed, because when it hits the limiter it will make a dull knock.

Removed shaft

The camshaft has a great influence on the pressure in the lubrication system. If the gaps between the bed and the camshaft are large, then the pressure will be low, and as a result, unsatisfactory lubrication of other parts.

Causes

The main malfunctions that result in the need to replace the camshaft are its wear, the appearance of various scuffs and grooves on the bearing journals. Likewise, replacing the camshaft is necessary if it is found to be deformed or cracked. When such malfunctions occur, the power unit loses power and also begins to function intermittently. Problems with the camshaft are identified by a knocking sound in the cylinder head.

The camshaft on the “six” is rarely removed. In addition to the above reasons for replacing and reconfiguring the power unit. After this, you can notice a significant increase in power, like in sports cars.

How to remove the camshaft of a VAZ 2107

Replacing the VAZ 2107 camshaft begins with its dismantling. To do this you need to do the following:

place the car on a level surface;
wait until the engine cools down;
clean the engine head cover from dirt;
remove the air filter, disconnect the cable, tip and rod of the throttle valve drive, remove
fuel hose from the bracket (on a car with a carburetor engine);
disconnect the air supply hose, vacuum hose and remove the fuel filter from the bracket (on a car with an injection engine);
Using a 10mm wrench, unscrew the nuts securing the cylinder head cover;
remove the washers from the cylinder head cover;
release the wiring harness, crankcase exhaust and power steering hoses, and the headlight hydraulic adjustment tube from the bracket mounting;
remove the cylinder head cover from the studs;
remove the gasket;
set the camshaft position so that it corresponds to the end of the compression stroke in the fourth cylinder;
Use a chisel to bend the petal of the camshaft sprocket lock washer;
engage first gear to prevent crankshaft rotation;
Using a 17mm wrench, unscrew the camshaft sprocket mounting bolt;
remove the bolt together with the lock washer;
Using a 10mm wrench, unscrew the two nuts securing the chain tensioner;
remove the tensioner;
tie the chain to the camshaft sprocket with wire so that it does not jump off;
remove the sprocket and chain, move it forward;
Using a 13mm wrench, unscrew the nuts securing the camshaft bearing housing (this must be done evenly so that the housing does not “lead”);
remove the bed along with the camshaft from the studs;
use a 10 mm wrench to unscrew the two nuts securing the thrust flange;
remove the flange from the groove in the front journal of the camshaft;
pull the camshaft out of the bed (bearing housing).

If signs of wear are visible on the camshaft journals or cams, the camshaft needs to be replaced. It also needs to be changed if cracks or deformation appear. Sometimes the cause of a knocking noise may be wear on the camshaft housing bearings. In this case, it is enough to replace only the bed.

Replacement Guide

The work of removing the crankshaft on a VAZ 2106 is somewhat labor-intensive, but a driver with little experience can do it. We do not need special equipment or special tools to work.

Wrenches for tightening and loosening bolts

Sequencing

To get to the crankshaft, you first need to remove the air filter and housing.
Next, disconnect the choke cable.
Gas damper drive.
Clean and wash the valve covers thoroughly. Usually dust and dirt accumulate on it, otherwise they may get inside the motor.
Now you need to unscrew all the nuts and remove the valve cover. Experts recommend replacing the gasket when removing the valve cover. When purchasing, buy a rubber-cork one, as it holds oil much better than rubber.
By removing the cover, we gain access to the camshaft; in most cases it is very dirty.
Now you need to loosen the camshaft sprocket fasteners. To prevent the motor from turning over, insert a screwdriver between the sprocket and the chain.
Important! Be sure to align the mark on the crankshaft and the camshaft sprocket. You must strive to ensure that the mark on the crankshaft pulley is against the long mark, and the mark on the camshaft sprocket is against the protrusion on the camshaft bed.
After alignment, we proceed to removing the chain tensioner.
Unscrew the nuts with a wrench.
Remove the tensioner.
We remove the star, which is located on the guide pin.
After unscrewing the bolt securing the sprocket, remove the sprocket. A hammer may be needed here.
We tie it to a chain.
Now you need to unscrew the nuts securing the crankshaft and remove it.
By the way, it will be noted that if a stud with a nut is turned out, then it is screwed back in with a special stud turner.
Next, we inspect the camshaft and replace it if necessary.
The shaft is clamped according to the diagram. The tightening order must be observed. The tightening torque is also important. On a VAZ 2106 car, the tightening torque is 18.3 N/m.
When assembling, be sure to check that the marks are aligned correctly. If they are out of order, they need to be set correctly.
Finally, adjust the tension of the chain and valves.

Installation of camshaft VAZ 2107

The cylinder head camshaft is installed in the reverse order of removal. Before installing the part into the housing, it is necessary to lubricate the support journals with engine oil. When assembling, you should pay attention to two important points:

correspondence of the marks on the camshaft and on the sprockets of its drive;
tightening torque of the camshaft housing nuts.

First, you need to properly tighten the camshaft nuts. The nominal tightening torque of the nuts is 2.2 kgf•m. You cannot immediately tighten the fastening to such a torque. The VAZ 2107 camshaft is tightened in three to four stages so that the body is pressed evenly, without distortions. The nuts should be tightened from the center to the edges, in accordance with the “tightening chart” (see figure).

When the camshaft is installed, it is necessary to set its position relative to the crankshaft. There are marks on the camshaft bed, the front engine cover and the crankshaft and camshaft sprockets that should be followed. Even if the drive chain has been securely attached to the sprocket, when installing the camshaft, make sure that its position matches the position of the engine crankshaft. To correctly set the marks on the VAZ 2107 camshaft, you must perform the following steps:

make sure that the mark on the crankshaft pulley is located opposite the long mark on the front engine cover (this corresponds to the top dead center of the fourth cylinder);
install the sprocket on the camshaft and make sure that the mark on it matches the mark on the “bed”;
put the chain on the sprockets without disturbing the position of the shafts;
make sure that when the chain is tensioned, the marks match;
tighten the camshaft sprocket bolt;
turn the crankshaft two turns with the wrench;
check the alignment of the marks on the camshaft and crankshaft;
if necessary, change the position of the chain on the camshaft sprocket;
Tighten the camshaft sprocket bolt and secure the lock washer.

After this, all that remains is to adjust the chain tension using the tensioner and complete the assembly by installing the cylinder head cover and other parts.

Video “Replacing the shaft”

This video shows how to properly remove and install the camshaft, replace rockers, springs and other shaft components on a VAZ 2106 car. And also at what torque the tightening occurs.

In the VAZ 2106 car engine, the camshaft plays a key role, which drives the valves. Thanks to it, timely intake of the air-fuel mixture into the combustion chambers and release of gases from them occurs, and according to the operating cycle. The shaft is located in the upper part of the engine, under the cylinder head cover (cylinder head). There is a sprocket on the camshaft with which it is connected to the crankshaft. One revolution of the crankshaft corresponds to two revolutions of the camshaft.

The main malfunctions of the camshaft are risks and scratches on the journals, deflection relative to the axis of rotation, increased wear, and multiple scuffs. If the camshaft journals are worn excessively, the oil pressure in the system decreases. But this option is also possible if the seats for the camshaft bearings are destroyed. And if you can install new journals for a small amount, then in the case of seats you will have to replace the cylinder head. Tuning is often performed, which requires the installation of a new, lighter camshaft on the VAZ 2106.

Of course, every owner of Soviet cars sooner or later is faced with their repair and adjustment of various components. Although today the presence of Soviet-era cars on the roads is gradually decreasing, such repair work has not lost its relevance. And in this article we will talk to you about how to properly adjust the valves on a VAZ 2106 with your own hands.

Dipstick

Probe Set of probes

If the gap is in the wrong position, or some errors are made in its adjustment, the car may consume much more fuel than it should, but at the same time its power may decrease significantly.

Before you begin, you should understand that this procedure requires certain knowledge and may take some time. The work must be carried out following a certain algorithm and divided into several main stages:

Initially, the car should be in as level a position as possible. Access to the engine compartment must be free.
Also make sure that the work area is well lit. If the work will be done in the garage, it is recommended to use an additional portable lamp, thanks to which you will be able to see even the most difficult to reach places.
The power unit must be cold to ensure safety standards.

During disassembly you must:

Remove the air filter.
Next, disconnect all possible connections directly from the filter cover.
Also remove the cylinder head covers, choke cable and accelerator rods.

To make the disassembly process more convenient:

Remove the distributor cover.
Also rotate the crankshaft until the marks on the pulley and the oil seal cover match. This position of the crankshaft will indicate that the piston of the fourth cylinder will be at the compression point.

And so, in order to correctly adjust the valves, it is necessary to strictly adhere to a certain order. The adjustment order must not be violated.

Here are several videos for your attention - examples of how valves are adjusted:

Try to follow the algorithm to avoid all sorts of mistakes that could lead to a more serious problem.

Sequential algorithm of actions

If you have maintained the required position based on the marks, be sure to pay attention to the clearance of camshaft cams 8 and 6. Remember such an important fact as counting

You need to start it from the star mark, which is located closer to the windshield. Start counting from this cam. Next, take the dipstick and place it under the camshaft, which is located just above the rocker. If the probe is loose, slightly loosen nut 17 of the rocker, where measurements are taken. To avoid scrolling, slightly loosen the nut to 13. Next, you need to tighten the nut to 17, after which the gap is measured. You need to make sure that, when penetrating the gap, the probe fits tightly, with little effort, but so that it does not bend. If this result has been achieved, you can proceed to the next cam. Take the key and rotate the shaft 6 strokes. Pay attention to the mark, it should be at 9 o'clock, and coincide with the mark located on the pulley. Now you can begin adjusting cams 4 and 7. This process is identical to the one written above. Next, we rotate the shaft 180 degrees so that the mark located on the sprocket takes the position at 6 o’clock. Make sure that the mark on the pulley clearly coincides with it. Now you can adjust cams numbered 1 and 3. We rotate the shaft to the 3 o’clock position, after which we adjust cams 2 and 5. At the final stage, you need to rotate the crankshaft using the starter, after which you should check the work performed and tighten all the nuts. Installation of previously dismantled parts must be carried out strictly in the reverse order. If there is a need to change the cover gasket, this can be done during the assembly process.

Removing and installing the camshaft

Removal is most often necessary either during a major overhaul or for replacement in cases of failure. To carry out the work, the following tools are required:

heads for 10, 13 and 17;
handle with ratchet;
knob;
extension cord with cardan;
socket wrench 13;
device for mounting and dismantling the VAZ camshaft.

First, the valve cover is removed, which is bolted to the cylinder head and has a rubber gasket. Try not to damage it, otherwise oil may leak in the future. After this, the timing chain tensioner is unscrewed. It is located on the right side of the engine when viewed from the interior. The camshaft gear is turned by the head to 17.

For convenience, place the car in gear and place wheel chocks under the rear wheel. Move the gear to the side; if necessary, you can pry it off with a convenient tool. Now all the nuts that secure the camshaft housing must be unscrewed. To make the job easier, use a wrench first.

How to adjust valves on a VAZ 2106?

On a VAZ 2106 car, it is recommended to adjust the valves every 10-15 thousand km. mileage The optimal value has been selected, because all this time the engine will operate stably. When the gap changes, minor “defects” will begin to appear: valve knocking with a sharp increase in speed, a decrease in throttle response and engine power.

The problems go so far as to cause the engine to stall at high speeds at operating temperature. It is also necessary to adjust the valves after carrying out work related to repairing or replacing the camshaft. In this case, adjustment is inevitable, since the 2 camshafts may differ from each other. To work you will need the following tools:

a set of keys;
open-end wrench 17 with good leverage;
special key 38 for turning the crankshaft;
flat probe 0.15 mm thick.

If you look closely at the case in which the dipstick is stored, you will see several numbers indicating the sequence of valve adjustment. Pay attention to the temperature: 20 °C is optimal for setting. But if before this the VAZ camshaft was replaced, and the weather is warm, then you don’t have to look at the temperature.

So, first remove the cylinder head cover. Please note that the valves should be counted from the front edge of the internal combustion engine. After this, put the piston of the 4th cylinder in the upper position using a 38 key. Valves “6” and “8” are closed, therefore, the gap between the lever and the cam will be the largest. Place the dipstick and check the gap. The optimal one is one in which the probe can be moved with some effort. If the gap is smaller or larger, the dipstick does not move or passes freely, then proceed with adjustment.

To do this, you need to work with two 17mm wrenches: with one you loosen the lock nut, and with the second you turn the bolt to adjust. Moreover, you should not make many turns with the adjusting bolt; you need to slowly move the feeler gauge while unscrewing or tightening it, so as not to miss the permissible gap value. Afterwards, the locknut must be tightened and once again make sure that the gap is correct. If necessary, the valve is re-adjusted. Valve adjustment procedure:

The crankshaft rotates 180°, which corresponds to a quarter turn of the camshaft. To control the position, it is necessary to use the marks on the crankshaft pulley, as well as on the camshaft. As a last resort, simply remove the distributor cover and perform control using the slider.

Please note that one revolution of the crankshaft is half a revolution of the distributor axis. After the adjustment is completed, assembly is performed. If the rubber gasket is damaged, it should be replaced with a new one.
