Replacing the alternator belt with Renault Logan seems to be a responsible operation, due to the importance of the unit and the functions that it performs.
Reasons to replace the belt on a Renault Logan
The Renault Logan manufacturer regulates the replacement of this unit (including brushes) due to failure after every 60,000 kilometers (this also applies to units with 16 valves), however, the responsible car owner must be guided by several prevention rules to extend the life of the part.
Every 15,000 kilometers on units equipped with 16 valves, it is necessary to check the belt tension and, accordingly, the performance of the entire structure.
If there are no cracks on the rubber of the belt, and the condition of the pulley is satisfactory, it is not necessary to replace the part. Otherwise, it will be necessary to carry out work to repair and install a new part, replace the pulley.
Given the peculiarity of the Renault Logan equipment, on which air conditioning and power steering (Power Steering) could be installed together, separately, or may not be on the car at all, such equipment is typical for engines with a volume of 1.6 and 1.4 liters (this also applies to engines with 16 valves ).
What could be the problems
- A characteristic feature of the appearance of a malfunction is an atypical whistle from the motor shield (that is, the whistle of the belt itself). In this case, the belt and pulley on the Logan may simply not be tensioned, and it is necessary to increase the tension of the belt with a tool, as a result of which the whistle will disappear. However, in the event of a sound due to a broken regulator and other malfunctions, it may be necessary to replace the unit.
- In the worst case, when the whistle increases, the part (belt, pulley) will need to be replaced.
- Also, whistling is typical for parts with a faulty regulator. If a whistle appears and a regulator failure is diagnosed, this assembly must be dismantled and subsequently replaced.
- Another cause of failure may be the failure of the bearings of the structure. Bearings can fail for various reasons.
When replacing a part with a new one, the Renault Logan car owner with a 1.6-liter power steering must take into account the manufacturer's recommendations when purchasing a new unit.
There are many analogues on the market, however, if the owner wants to get factory reliability parameters, attention should be paid specifically to Bosch parts.
Replacing the belt on Renault Logan cars with air conditioning and power steering
This Logan equipment with air conditioning and power steering is most often found on Renault models with a 1.6 engine, with power unit 1.4 is rare. Most often, this equipment is found on cars equipped with 16 valves.
How many steps does this procedure contain? We do everything cold.
- In the engine compartment, using a 13 wrench, it is necessary to loosen the screw securing the bearing rollers.
- Next, you need to fix the bracket with the alternator housing of the Renault Logan regulator.
- Then it is necessary to remove the drive and rings from the devices for working with air conditioning and power steering. Also, when performing this procedure, you should replace the rollers, since these parts change along with the belt.
- Using the key, it is necessary to disassemble the tension roller and the roller structure (this manipulation is also carried out using the 13 key).
- After replacing the rollers and installing a new part (belt drive, rings), the assembly of the entire structure must be carried out in the reverse order. Before installation, you need to fix a new roller bracket for better fixation of the structure, tighten it.
- Then the structure (drive, rings) is assembled in reverse order. The whole process is shown in detail in the video.
A feature of the belt in this design is the presence of five streams, while the pulleys of the drives of additional devices have one more.
Part replacement for Renault Logan with power steering and without air conditioning
For replacement on a 1.6-liter power steering engine without air conditioning, no special tools are required (except for replacing the generator itself). On units with 16 valves, this modification is rare. This procedure also goes through several stages:
- In the Renault engine compartment by 1.6 liters, it is necessary to tightly compress and check the tension of the part and the serviceability of the bearings in the future, if anything, tighten everything. If this tension is strong enough, it is necessary to loosen the fastening, which is held on by screws.
- Then, loosen the adjusting screw, not tighten it, and replace the idler or bearing when the voltage decreases.
- Next, you need to change everything, namely: to carry out the installation process of new parts and assemble the entire structure in reverse order, tighten the parts, as shown in the video, and also check the operation of the regulator.
- For reliable repair work, the manufacturer recommends using a circuit and a tester to control the mains voltage. Thus, it is possible to more accurately determine the moment of belt replacement, as well as the optimal performance of the structure.
Steps to replace a part on a car without a climate system and power steering
The design on the model in this configuration without power steering is a little simpler and, accordingly, it will cause the owner the least trouble in operation and repair, since this version is rare on engines with 16 valves.
However, the disadvantage of this arrangement during repair is the possible damage to the generator due to a tightened belt.
The generator is located in a different place, access to it and to its parts is correspondingly easier - the whole process of removing and installing a new part is quite simple.
- Direct removal of a non-working part and its subsequent repair (or individual parts, for example, rings, pulley) is carried out from the crankshaft.
- In this case, it is advisable to check the exact tension of the new belt in order to avoid damage to the generator, if anything, tighten it. This can be done using a special tester or other equipment, so check the health of related components - the regulator and bearings. However, often the owners have to be content with the strain on the "eye", since the measuring equipment is quite specific, it is correct to tighten everything up.
Generator brushes on a car - maintenance
When carrying out maintenance of the brushes, preventive work is carried out not only for the brushes, but also for the generator shields in the following sequence:
- It is necessary to remove the contact brushes of the generator.
- Then you should get the chassis levers (for the convenience of maintenance work with brushes).
- Next, you need to remove the fixing elements of the upper shield.
- The next step is to remove the engine crankcase protection. The protection is mounted on several bolts. When dismantling the protection, precautions must be taken.
- After removing, disassembling the shields, they are cleaned, dirt is removed and the elements are installed.
Summing up
As a result, replacing the alternator brushes on a French car does not present great difficulties for a motorist who has little experience in repair work, and preventive measures are available to every owner. Fixing problems is not so difficult, you should try to do it yourself.
With regular inspections of Renault Sandero (every 15 thousand km.), You should check if it has weakened. Also control the absence of cracks, other structural defects.
Alternator Belt Replacement
Drive Adjustment and Spare Parts Installation
If the tension roller, it will squeak when rotated. When disassembling the assembly, excessive wear is determined visually. Its replacement, as a rule, is carried out simultaneously with the belt, therefore it will be necessary to perform the operations above in full, or only free access to the work site. 
The support roller is attached using one, and the tension roller - with two bolts. In order to properly adjust after replacement, the manufacturer advises using a special tester. Using this device, you can also check the performance of the belt by its ability to maintain a given tension. It is worth noting that in the absence of a certain flexibility, the generator may be damaged. That is why it is recommended to purchase a good quality tension roller. Failure to do so can cause major problems.
How to replace the power source?
This Renault Sandero unit is quite complicated, so experts advise to repair it only in the conditions of a specialized workshop, using methods approved by the manufacturer. In many cases, replacement is more appropriate. It is produced according to the following scheme. 
- First, it dismantles the belt with the release of the roller tension, using the above sequence of actions.
- Next, disconnect the block with wires. The latch on the housing is pressed with a flat-blade screwdriver. The nut is unscrewed and the lead wire is separated from the clamp.
- The fastening points of the compressor, the GU pump are loosened. Hoses and pipes are not separated, and the corresponding blocks are shifted to access the bolts that fix the generator. This will make it easier to retrieve later.
- When the dismantling is completed and no additional malfunctions have been identified, the assembly is performed in the reverse order.
- The belt is installed. It is adjustable using a tension roller.
Upon completion of all work on the repair of the Renault Sandero car, the on-board network is connected.
In winter, this belt began to squeak. But now he began to squeal so that it was a shame to start the car. There is a lot of information about the replacement process, but nevertheless I will add my experience to the general piggy bank. How what and where to twist is described in detail.
As probably all loganos / sanders already know, the tensioner pulley and the bypass roller are exactly the same and you can save a lot by buying two bypass rollers for replacement. I used a Patron PT36031 and a FED 6PK1820 belt.
The roller has an NSK bearing, and the belt is made of high-quality EPDM rubber, so there are no problems with them. But their biggest advantage is the price. Roller - 1.02 €/pc. Belt - 3.85 €. Just a holiday.
Remove the wheel and unscrew the plastic nut:
We take the mudguard down (it is not necessary to remove it):
Here is the tensioner pulley:
Using a 15 key clockwise for the roller bolt, we press the tensioner spring. The manual says that you need to insert something into the hole to fix the roller in the cocked position, but I didn’t see any holes, I spat, and just threw off the belt.
The manual says to put the belt 5RK1747 leaving one stream on the pulleys empty, but I had the original 6RK1822. Therefore, as a replacement, I took the same one, only 1820, 2 mm shorter. To be honest, I barely dressed him either, I have no idea how they want to dress 1747 ...
Removed tensioner pulley - PILENGA PT-P4756 1507 Bearing E6203-2RS-Y
With a key of 13, we unscrew the bypass roller. In fact, it is difficult to get to it, but you can crawl, although you have to do everything by touch.
29 ..Replacing the drive belt for auxiliary units of the engine 1.4–1.6 (8V) Renault Sandero, Stepway
In accordance with the maintenance regulations, we replace the auxiliary drive belt every 60 thousand kilometers or after 4 years (whichever comes first), regardless of its condition. We perform work on a viewing ditch or overpass.
At each maintenance, we recommend checking the condition of the belt.
The belt must be replaced if cracks, tears and delamination of rubber from the fabric base are found on it.
Depending on the vehicle configuration, there are three options for auxiliary drive circuits.
Option 1
Scheme of the drive of auxiliary units of a car with power steering and air conditioning:
2 - tension roller;
3 – a pulley of the pump of the hydraulic booster of a steering;
4 - generator pulley;
5 – an air conditioner compressor pulley;
6 - support roller;
7 - belt
The belt tension of a car with power steering and air conditioning is automatically adjusted by a tensioner. To replace the belt, remove the right mudguard of the engine compartment (see).
To loosen the belt tension, from below the car…
... we put a ring wrench or a “13” head on the tension roller mounting bolt and turn the roller bracket clockwise, overcoming the spring force of the tensioner, until the hole in the roller bracket and the recess in the device body are aligned (for clarity, shown on the removed engine).
We fix the roller bracket by inserting a “6” hexagon or a rod with a diameter of 6 mm into its hole and the recess in the body of the tensioner.
Remove the accessory drive belt.
Marking of the drive belt of auxiliary units of a car with power steering and air conditioning - 5K 1747 (five-strand, 1747 mm long). When replacing the belt, the idler and idler rollers must also be replaced.
To replace the cam roller...
... with a ring wrench or a “13” head, we unscrew the bolt of its fastening ...
... and remove the bolt with the protective cover of the roller.
Remove the support roller.
Remove the tension roller in the same way.
If it is necessary to replace the tensioner (for example, if the spring breaks) ...
... with a “13” head, we unscrew the two bolts securing the tensioner housing ...
... and remove the tensioner assembly with the roller.
Install the removed parts in reverse order. Before mounting the belt, the idler pulley bracket must be turned clockwise and locked (see above).
When installing the belt, we lay it on the pulleys and wind it under the tension and support rollers in accordance with the drive diagram.
Automatic Tensioner Assembly:
1 - tension roller;
2 – roller bracket;
3 - body
... so that it is shifted to their outer edge 1, and the inner stream of pulleys 2 remains free.
After installing the belt, slightly turning the tension roller with a key, remove the latch. Then, with the “18” head with a ratchet, we turn the crankshaft clockwise three turns for the bolt securing its pulley in order to achieve the correct position of the belt.
Option 2
The manufacturer recommends checking the tension of the belt of auxiliary units of a car with power steering and without air conditioning using a special tool (tensometric tester) at a RENAULT dealership. Considering that the belt may need to be changed on the way (for example, when it breaks), away from the service, we will show a method in which you can approximately estimate the belt tension.
Scheme of the drive of auxiliary units of a car with power steering, without air conditioning:
1 – a pulley of a drive of auxiliary units;
2 - tension roller with bracket;
3 - adjusting bolt;
4 – a bolt of fastening of an arm of a tension roller;
5 - generator pulley;
6 – a pulley of the pump of the hydraulic booster of a steering;
7 - belt
Remove the right mudguard of the engine compartment (see. "Removing the mudguards of the engine compartment"). From the bottom of the car with your thumb, press the belt in the middle between the pulleys of the power steering pump and crankshaft. With a pressing force of ~10 kgf, the belt deflection should be 6–8 mm. To tension the belt, loosen the two bolts 4 fastening the tension roller bracket and turn the adjusting bolt 3 clockwise. After tightening the belt, tighten the tension roller fastening bolts.
Do not overtighten the belt! Excessive belt tension leads to premature failure of both the belt itself and the alternator bearings.
To replace the belt, turn the adjusting bolt 3 counterclockwise by several turns and loosen the bolts 4 for fastening the tension roller bracket. After loosening the belt tension, remove it from the pulleys. Marking of the drive belt of auxiliary units of a car with power steering and without air conditioning - 5K 1110 (five-strand, 1110 mm long).
When replacing the belt, the tensioner must also be replaced.
Install the accessory drive belt in reverse order.
The pulleys for the drive of auxiliary units, the generator, the air conditioning compressor and the power steering pump are six-stranded, and the drive belt is five-stranded.
We put the belt on the pulleys so ...
... so that it is offset to the inner edge of the 1 pulleys, and the outer stream of the pulleys 2 remains free.
We adjust the belt tension (see above). To accurately check the belt tension, you must contact the service.
