Adjustment of valves "Renault Logan" (1.6, 8 valves) with own hands. The order of valve adjustment on the "Renault Logan"

Owners of cars "Renault Logan" after that,as the warranty period expires, they face the need to self-service their cars. One of the necessary procedures is the adjustment of the valves. "Renault Logan" is arranged quite simply. So, you can do this procedure yourself and not spend money on STO. The valve clearance adjustment scheme is simple enough and is available even for those who have never had experience in this matter.

These cars are on the market inModifications with engines of 1.4 and 1.6 liters. There are two versions of 1.6-liter engines. The 8-valve model and the 16-valve model are offered. On the sixteen valve unit, manual adjustment of the gaps is not provided. For this, the construction has hydraulic compensators. But on the eight-valve adjustment of gaps is done manually. Let's see how this is done.

Purpose and functions

Inlet and exhaust valves are one of the most importantdetails of ICE. Due to them, combustors will get fuel and burnt products to the exhaust system. For most of the operating cycle, the valve is closed. The discovery takes place for a rather short time. These elements are now being given certain requirements.adjustment of valves reno logan Valves must not interfere with the output of productscombustion. When they are open, they carry out their tasks with a minimum frictional force, clearly perform their function, work at a certain moment. Also, the valve must have a strictly defined clearance. This prevents the gases from escaping out of the chamber at the moment of ignition of the mixture.

Why regulate?

First of all, let's find out why we needadjustment of valves. Renault Logan has its own compensating valve clearance. This is the specified distance between the adjustment bolt and the drive shaft. Specialists of "Reno" provide for certain gaps. They also allow to compensate for the expansion of metal parts during their heating.

If untimely adjustment and incorrectgaps there is a risk of accelerated wear of parts and engine components. When the parameters are too high, the power and other characteristics of the power unit are reduced. The combustion chamber can not be fully filled with the fuel mixture to the desired extent. A small gap leads to a loss in the combustion efficiency of the combustible mixture. In this case, there will be low compression. Also there is a risk of burning the valve seats and forming deposits.

If you operate a car with unresolved gaps, this will lead to serious malfunctions in the gas distribution system. As a consequence, expensive repairs.

Periodicity of the operation

How often should the clearance be adjustedvalves? "Renault Logan" according to the regulations and recommendations from the manufacturer is to be adjusted every 80-100 thousand kilometers. However, in reality these figures are much lower.Reno Logan Valve Adjustment Bolts To this car in the city streamto hold confidently, you have to squeeze out all the power and torque that this unit is capable of. This operation does not pass without a trace for the motor. Thus, the details of the piston group wear intensively.

In Russian realities, this operation shouldrun at least every 60 thousand km. The engine will tell the owner about the need for adjustment. When the engine is running, distinctive knocking at idle will be clearly heard.

Norms of clearances for engines "Renault Logan"

French automaker recommendsSet a clearance of 0.1 to 0.15 mm for each intake valve. For graduation rates are from 0.25 to 0.3 mm. If all valves have been replaced, then the lapping gaps must be set. They should be from 0.20 mm to 0.25 mm.

Required Tools

To perform this operation, we need a standard set of tools.Valve adjustment Reno logan by own hands Need pliers, a set of measuring probes, car keys - 13 and 10, as well as a screwdriver.

How to adjust valves: preparation for surgery

So, the adjustment of the valves (Renault Logan 2004including) is always carried out only on a cold motor. Before performing the operation, it is recommended to tighten the timing belt if it is loose.

Procedure for performing the operation

The adjustment of the valves "Renault Logan" with their own hands begins with the removal of the cylinder head cover. You need to have a tool kit.Valve adjustment Renewal 1 6 8 ValvesThe first thing to do is unscrew the bolts thathold the air filter. There are four in total. Next, the L-shaped branch pipe from the filter to the valve cover is dismantled. Then remove the air filter housing. In the next step, it is necessary to disconnect the spark plug wires and also to remove the valve cover. The latter keeps on eight bolts.

After this, raise the front of the machinefrom the driver's door and turn on the gearshift fourth gear. The raised wheel is twisted until the letter F appears on the camshaft gear. It is necessary to observe the valve of the first cylinder. The letter appears almost immediately when the valve starts moving. In this case, for one complete revolution of the wheel of the car, the camshaft also makes one turn.

Then the gaps for the first cylinder are measured.Loosen the lock nut, and the bolt is clamped with pliers. Special gauges are used to measure gaps. After setting the required distance, screw the valve adjustment bolts on the Renault Logan auto. Further it is recommended to check the parameter again with a feeler gauge. The latter in the gap must move only when a certain effort is applied to it.Reno logan valve adjustment for gas The same operation is done for the thirdcylinder. If you rotate the crankshaft by half a turn, then you can adjust the gaps on the fourth cylinder. Then on the second. Next, the shaft needs to be turned for a full turn and check again for each gap. If everything is in order, the engine can be assembled.

Do not break such an order of valve adjustment on the Renault Logan. When servicing the car, always act according to the manufacturer's instructions.

Renault Logan and HBO

As for cars whose engineswork on gas, then the opinions of car owners and manufacturers of gas-cylinder equipment diverge. Manufacturers of modern equipment of the Euro-4 class claim that with these installations, the Renault Logan car does not need to adjust the valves for gas, since the injectors are accurate and modern. The entire operation of the system is electronically controlled.adjustment of valve clearances reno logan Car owners claim that to adjust the clearancesIt is necessary, and this operation should be done more often. So, many perform tuning every 20-30 thousand kilometers. As for the gaps, for intake is considered the norm of 0.15 mm. For graduations - 0,30 mm. Recall that these parameters are suitable for propane-butane.

Helpful Tips

To easily and simply put the piston firstcylinder in the TDC, firstly the camshaft is exposed to the eye. Then it is rotated in such a way that the two heels of the rocker arms, on which the adjustment of the valves are performed, could rest against the occipital part on the shaft cams.

The adjustment process can be greatly simplified.After the cover is removed, from the flywheel side at the end of the camshaft you will find a mark in the square part. The stain made by the enamel will look up if the piston in the first cylinder is set at the top dead center. To move the shaft, car owners are advised to include not the fourth, but the fifth gear.order of valve adjustment for reno loganAfter the adjustment of the valves for the firstcylinder will be finished, go to the exhaust valve of the fourth cylinder. The suspended wheel is rotated further and adjusts the gap. How are the valves adjusted? "Renault Logan" is configured in the second cylinder. The procedure is similar to the operations on the first. By what scheme is the valve adjusted? "Renault Logan" is configured by the following algorithm - 1-4-2-3. Each digit is the serial number of the cylinder.

Conclusion

This is how the valves are adjusted."Renault Logan" (1.6, 8 valves) can be serviced by yourself. In fact, this operation is really simple, and it can be performed by a car enthusiast of any level - both beginner and experienced. Also, self-regulation is a good way to save money. After all, the SRT for this service is taken a considerable amount.
