Lada Largus - replacement of the drive belt for auxiliary units 8-cl. engine

Lada Largus, replacing the belt on an engine with 8 and 16 valves is different. Today we will talk about replacing the drive of auxiliary units on both types of Lada Largus engines. The manufacturer requires replacement every 60 thousand kilometers or after 4 years of operation, if the 60 thousand mark has not been passed. In addition, the drive belt patterns with air conditioning and without air conditioning are different. Our article today is about all this.

Types of alternator belts

For the generator, the developers used different types of belts depending on the configuration of the car with auxiliary units.

So, the following products are distinguished:

The LADA Largus station wagon is not equipped with a hydraulic power steering pump and an air conditioning compressor. In this simplest version, an alternator belt from Renault with the article code - “117200593R” (“6PK 837”) will be used.
The car is equipped with a power steering pump, but there is no air conditioning compressor (K7M engine). The alternator belt “5PK1110”, the length of which is 1110 mm, is suitable here. By the way, the product is made with five rivulets.
If the Lada Largus has in its arsenal both power steering and an air conditioning system for the interior space, then for such a “stuffed” configuration the manufacturer offers a “6PK1820” drive belt. The length of the product reaches 1820 mm, but there are already six streams.

Regulatory requirements for belt replacement

Regardless of whether the car is equipped with comfort and safety options, regardless of whether the model has 8 or 16 valves, the manufacturer recommends replacing the generator unit drive belt after this period:

60 thousand km or a four-year period if the car is equipped with a power steering system, but there is no air conditioning;
120 thousand km, when both mounted units are included in the configuration.

There are also cases of forced replacement of previously designated intervals. This is caused by the appearance of cracks, tears and other defects on the surface of the belt that are unacceptable for further use.

Removing and replacing the generator

Removal of the generator, with or without air conditioning, is required only in case of repair or replacement of the generating device on the Lada Largus model. It is better not to do this unless absolutely necessary.

In this case, you can remove the generator in different ways. This directly depends on the configuration in which the Lada Largus is presented.

The options may be the following, which affect the dismantling and installation scheme:

K7M engine without power steering and air conditioning;
K7M engine with power steering, but without air conditioning;
with power steering and air conditioning;
K4M engine without air conditioning, but with power steering.

But regardless of the configuration and equipment, before removing the generating device on all versions, you need to do the following:

install the machine on a lift with a lifting capacity of at least 3.2 tons;
turn on the handbrake;
turn off the ignition;
lift and securely secure the hood;
disconnect the negative terminal from the battery.

Now each situation must be considered separately. This will clearly allow you to understand exactly how to remove and replace the generating device.

K7M engine without air conditioning and power steering

With this variation of equipment, the dismantling and replacement procedure is as follows:

remove the front right wheel;
remove the engine splash guard on the right side;
remove the front arch skin from the right front wheel;
remove the protective cap from the nut;
disconnect the wiring harness from the generator;
using a 13mm socket, unscrew this nut under the cap;
disconnect the wire lugs from the existing B+ terminal on the generator;
cut the old belt and remove it, since it is still not suitable for reuse;
Using a 10mm socket, unscrew the mounting bolts from the bottom and top that hold the generator to the bracket;
remove the problem unit;
replace the tension and support rollers;
secure the new drive belt;
tighten the mounting bolts;
for the bolt fixing the generator to the bracket, use a torque of 21 Nm;
for wire fastening nut 14 Nm.

At this point the replacement can be considered complete. Check the node for correct operation. If everything works correctly, then complete the full assembly.

K7M engine without air conditioning, but with power steering

Here the instructions will look like this:

remove the protective cap from the nut, disconnect the wiring harness and unscrew the nut itself with a 13mm head;
disconnect the wire lugs from the generator terminal B+;
Unscrew the adjustment bolt and the upper bolt securing the adjustment bar approximately 3-4 turns using a 10mm socket;
dismantle the front right wheel, remove the mudguard and arch casing;
taking the head at 10, make 3-4 turns of the lower bolt securing the bar to loosen the belt tension;
remove the belt itself;
Using the same head, unscrew the lower mounting bolts that hold the generator on the bracket;
unscrew the upper bolt connecting to the bracket;
remove the generating device from the machine;
reassemble in reverse order;
for attaching the generator bolt to the bracket, use a torque of 21 Nm;
for the tension roller adjustment bar mounting bolt, also 21 Nm;
the generator wire connection nut requires a torque of 14 Nm.

In addition to replacing the belt, you will also need to install a new tension pulley.

Equipment with air conditioning and power steering

This is quite a good package, since here the driver can count not only on easier rotation of the steering wheel due to the hydraulic booster, but also on comfortable conditions in the cabin created by climate control equipment.

As for replacing the generator, the procedure is as follows:

remove the front right wheel;
remove the front bumper;
using a 16mm spanner, turn the tension roller clockwise;
lock the tension roller using a 6 mm hexagon;
remove the drive belt;
unscrew the air deflector fastenings and then remove the reflector itself;
Using a 10mm socket, remove the upper mounting bolts of the radiator bracket to the body;
remove the brackets;
remove the cooling radiator together with the air conditioner condenser from the lower mounts;
to do this, carefully move it towards the left wing;
Using a 13mm wrench, unscrew the fastening nut of the generator wire and remove the wire;
disconnect the wiring harness from the generator;
taking the head 10, unscrew the fastening bolt that holds the generating device;
use the same head to unscrew the lower fastening and remove the generator from the car;
perform assembly with a new device in the reverse order;
tighten the bolt securing the generator to the bracket to a torque of 21 Nm;
the wire fastening nut requires a torque of 14 Nm.

This is not to say that the procedure is easy. Some people are scared by the fact that it is necessary to remove the front bumper and radiator. Yes, here the scheme turned out to be not the most convenient. Although in reality, almost every Lada Largus owner, having theoretical knowledge and at least a little practical experience, will be able to cope with the task.

If you are afraid to take risks or are not confident in your own abilities, then it is better to send your Lada Largus to a specialist car service center.

K4M engine without air conditioning, but with power steering

In the case of this configuration of the domestic Lada Largus station wagon you will need:

remove the front wheel on the right side, remove the mudguard and remove the alternator belt;
unscrew the nuts securing the fuel rail protection, and then remove the protection;
disconnect the fitting from the fuel rail pipe;
Using a 13mm wrench, unscrew the nut securing the generator wire and remove the wire itself;
disconnect the wiring harness connector;
take the wiring aside;
Using a 13mm head, unscrew the power steering tube mounting bolt on the cylinder block;
Use a 10mm head to unscrew the bolt that secures the bracket for fixing the power steering pipeline to the generator;
remove the bracket;
unscrew the upper mounting bolt of the generator using a 10mm socket;
Using the same head, unscrew the lower mounting bolt;
remove the generator upwards along with the lower fixation bolt;
perform assembly in reverse order;
for the bolt securing the generating device to the bracket, apply a torque of 21 Nm;
a torque of 22 Nm goes to the bolt securing the power steering pipeline bracket to the generating device;
tighten the generator wire fastening nut to 14 Nm;
fuel rail protection nut also with a force of 21 Nm;
install a new belt;
complete the assembly of all dismantled elements.

Finally the work is completed.

The Lada Largus belt tension is adjusted automatically by a tensioner. To replace the belt, remove the right mudguard of the engine compartment. To loosen the belt tension, from below the car we put a spanner or a “15” socket on the tension roller mounting bolt.

Turn the roller bracket clockwise, overcoming the resistance of the tensioner spring, and remove the belt from the support roller. Remove the accessory drive belt from the pulleys. The marking of the drive belt for Largus auxiliary units with air conditioning is 6РК 1822 (six-strand, 1822 mm long). When replacing the belt, the support and tension rollers must also be replaced.

To replace the support roller with a spanner or a 13 socket, unscrew the bolt securing it and remove the outer cover of the roller. Remove the support roller and its inner cover.

Similarly, remove the tension roller. If it is necessary to replace the tensioner with a “10” head, unscrew the two bolts and remove the tensioner assembly with the roller.

Install the parts in reverse order. When installing the belt, place it on the pulleys and place it under the tension and support rollers in accordance with the diagram above.

The manufacturer recommends checking the belt tension of auxiliary units of a car with power steering and without air conditioning using a special device (strain gauge tester) at the dealer service. Considering that the belt (for example, if it breaks) may have to be replaced outside the dealership service center, we will show a method in which you can approximately estimate the belt tension.

Remove the right mudguard from the engine compartment. From below the car, use your thumb to press the belt in the middle between the pulleys of the power steering pump and the 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 3 clockwise . After tensioning the belt, tighten the bolts securing the tension roller.

Attention! Excessive belt tension leads to premature failure of the belt and tension roller, as well as accessory bearings.

To replace the belt, turn adjusting bolt 3 counterclockwise several turns and loosen bolts 4 securing the tension roller bracket. Having loosened the belt tension, remove it from the pulleys. Marking of the drive belt for auxiliary units of a car with power steering and without air conditioning is 5K 1110 (five-strand, 1110 mm long). When replacing a belt, you must also replace its tension roller. Install the auxiliary drive belt in reverse order.

Attention! The drive pulleys for the auxiliary units, generator and power steering pump are six-strand, and the drive belt is five-strand.

Place the belt on the pulleys like this...

How to replace the belt on a Largus with power steering and air conditioning?

Let us immediately note that the tension of the transmission element of the drive of the generator unit in this version of the equipment is adjusted autonomously due to the presence of a special device.

To replace the drive belt in LADA Largus we perform the following manipulations:

We dismantle the dirt protection panel of the motor, located on the right side of the unit.
We arm ourselves with a spanner wrench (or better a socket) with dimension “13”, with which we grab the tension element bolt. We press with a clockwise rotating force and, overcoming the resistance of the spring built into the assembly, we bring the bracket until the hole in it aligns with the same recess in the body.
Holding the key firmly in the achieved position, insert any rod with a diameter of 6 mm into the alignment of the holes. Here, a hex key with a dimension of “6” is perfect as such a locking device.
When the tensioner is fixed, the tension force on the belt disappears, and the consumable element can be removed from the units.
During this procedure, it is possible to check and, if necessary, replace the tension roller and its supporting counterpart.
Installation is carried out in the reverse order of removal. During this manipulation, we follow the following algorithm: first we lay the belt on the pulleys, then we place the corresponding branch of the product under the tension roller, and then under the supporting element of the system (also a roller).
Having completed the attachment of the transmission element, we remove the clamp and the tensioning component “sets” the belt under the “load”.
Now, using an 18-size wrench, we rotate the crankshaft several turns, after which we observe that the belt is installed correctly.
We return the protective motor shield to its original place.

To check the tension level of the transmission element on this version of the Lada Largus equipment, the manufacturer recommends using a strain gauge tester. However, such a device is available at the dealership, so we do things differently.

We remove the dirt-reflecting shield on the engine.
We move under the car (it must be hung or located above the pit).
We press on the lower branch of the belt with the strongest finger, forcing it to bend by about 7-8 mm. If the belt bends more, it means it needs tightening. This is done by loosening a pair of bolts securing the tension element bracket. Now we rotate the adjusting screw in a clockwise direction until the required tension level is reached. Tighten the previously specified bolts.

Attention! Do not try to over-tighten the belt, as this will cause premature failure.

To replace the belt drive in LADA Largus, we proceed similarly to the above algorithm, only we rotate the tension-regulating bolt in the reverse direction of the clock. This loosens the system and allows the belt to be removed from the hitch.
We install the belt with the air conditioner and tension it in the reverse order.

Attention! In this version of the layout, the pulleys of the specified mounted units are six-groove, and the belt itself, as already indicated, is five-groove. We lay the product in such a way that the belt is located as close as possible to the outer edges of all pulleys, and the internal stream on them remains free! Belt replacement is complete.

Lada Largus: replacing the drive belt for auxiliary units of an 8-valve engine

Reviews about replacing the alternator belt in Largus

Car owners rarely turn to the service center with such a question as replacing an alternator belt; in most cases, this operation is carried out as an accompanying operation during a scheduled technical inspection. Basically, the replacement is done with your own hands.

Pavel, Novorossiysk: “I’ve owned Largus for a little longer than a year; I used to have a ten with a regular 8-valve engine from a nine. I thought everything would be just as simple in Largus, I changed it in five minutes and moved on. With power steering and air conditioning, it’s not only comfortable to drive, but also difficult to replace the drive. It’s good that there are a lot of guides on this topic, I figured it out quickly.”
