How to remove a generator on a Daewoo Matiz?

Opening the hood, we find an expansion tank with coolant. We will need to drain it so that during further dismantling we don’t spill it on the floor. First prepare a small container to collect the coolant. A sparkling water bottle will suffice.

So, we disconnect the pipe that leads from the expansion tank to the throttle valve. To do this, we compress the clamp with pliers, pulling it back a little. This will allow us to remove the already mentioned upper pipe. We move the clamp closer to the engine shield for convenient removal and drainage of liquid from the pipe into a bottle or canister that we previously prepared. Since there is practically no pressure in the pipe, you don’t have to worry about it jumping out of the container. To drain the liquid more efficiently, start the engine and wait until all the antifreeze is drained.

Generator Daewoo Matiz.

The generator on Daewoo Matiz fails very often.
Many owners of Daewoo Matiz have encountered this problem. Neither the car itself nor the car owner is to blame for this, the reason is in the design features. The fact is that the diode bridge of the Daewoo Matiz generator with its negative plate does not directly touch the generator housing, but the contact passes through the studs for fastening the diode bridge and the rivets on which the Matiz diode bridge itself is assembled.

The contact turns out to be extremely unreliable; the rivets usually burn out. As a result, the diode bridge burns out. This is the cause of approximately 90% of Daewoo Matiz generator failures.

So, the actual repair of the Daewoo Matiz generator itself.

Necessary tools: 7mm head or wrench, E5 or regular 4mm head, soldering iron up to 100W, tester,

1. Remove the plastic cover of the generator. It is held on by 3 latches.

2. Using a 7mm head, unscrew the 3 screws securing the Daewoo Matiz diode bridge. And three screws with an E5 or 4mm head.

3. Unsolder the three stator leads that go to the diode bridge. We remove the diode bridge along with the relay regulator.

4. Unsolder the terminal connecting the diode bridge and the relay.

5. We check the rotor with a tester - it should be approximately 3.5 Ohms. Stator - the conclusions should be connected to ground in MegaOhms or infinity. Diode bridge - we check each diode separately, the tester is in the “diode check” position. If at least one is broken, we change the diode bridge. There is no way we can test the generator regulator relay at home, only with the help of a special relay tester, or with a working generator on a test bench.

6. We assemble everything in the reverse order, but with the new Daewoo Matiz diode bridge.

7. We can check the functionality of the generator under such circumstances only on the machine after its installation. Don't forget to charge the battery in advance!

8. The charging voltage of the generator on the Matiz should be 13.6-14.8 V, the charging indicator lamp should go out.

9. There is no point in looking for and buying a generator for a used Daewoo Matiz, since repairing a generator for a Matiz is not expensive, and even an already rebuilt Daewoo Matiz generator is about 2 times cheaper than new ones. Same quality and 6 month warranty.

K50 — mando matiz generator

Parktronic

Car air conditioners

Installing a car audio system yourself

K50 - mando Matiz generator Like all other generators with alternating current, the K50 - mando Matiz generator is equipped with a popular layout and design structure, together with a rotor and winding, a shaft with two ball bearings having two slip rings and an impeller in order to cool windings and bridge made of diodes.
On the K50 shaft - the mando Matiz generator has a pulley for the drive belt. The surface of the housing is made of silumin, between the parts in front and behind which a magnetic wire is clamped, with a stator winding of three phases placed inside its grooves.

Each terminal that the stator winding has is soldered to a bridge, which is assembled into a common module from a pair of radiator horseshoes that have a negative and positive charge. Diodes with opposite charges are placed in their body under pressure. This is done in order to simplify electrical connections by using improved heat dissipation from the crystals and at the same time connect the strong current leads of each diode when the Matiz alternator belt needs to be replaced.

Additional diodes K50 - daewoo matiz generator are located in the cradle of the insulation part of the structure and are soldered to the appropriate places with the leads.

replacing the Matiz generator belt The bridge of diodes is located in a common module, held by brass rivet bushings, which mechanically fasten the horseshoes of the bridge when the Matiz generator belt needs to be replaced.

Using a voltage regulator, the bridge is connected by soldering, which in turn is connected to the brush assembly.

A power bridge with diodes and three phases is a more loaded element.

An optimal current of 65/3 flows through any of its three arms

21.7 amperes plus approximately 1.5-1.7 amperes flow through each negative horseshoe diode, because they also act on several additional diodes.

The latter are designed to provide power to the voltage regulator with a rotor winding when Matiz generator repair is needed.

Replacing a Daewoo Matiz generator of one type with another.

Now let's talk about replacing the generator with a different type. If the car previously had a Delphi (Type “A”), and you want to install a Mando (Type “B”), you will have to replace the drive pulley. The fact is that the rotor of the Mando generator is driven by a toothed V-belt, while in Delphi it is driven by a flat poly-V-belt (ribbed belt). Changing the crankshaft pulley for such a task is expensive and pointless.

In such cases, they take the pulley from the old generator and put it on the new one. Since the pulleys are cast and massive, they last a very long time and will work with the new generator for more than one year. The pulley is removed from the generator by unscrewing a single nut.

If we talk about time, replacing a Matiz generator takes from 20 to 40 minutes, depending on skill and experience. Produced alone.

Set the rheostat to 4 cm. Checking the generator with an oscilloscope An oscilloscope allows you to accurately and quickly check the serviceability of the generator using the shape of the rectified voltage curve and determine the nature of the damage. Shape of the generator rectified voltage curve: I - generator is operational; II - diodes are broken; III - open circuit in the diode circuit of the stator winding. When the diodes of the rectifier unit and the stator winding are in good condition, the rectified voltage curve has a sawtooth shape. I Fig.

If the diodes are short-circuited, broken or there is an open circuit in the diode circuit of the stator winding, the shape of the curve changes sharply: Checking the voltage regulator The generator has a built-in small-sized integrated voltage regulator of the YaA type. It is a non-separable, non-adjustable unit and is located on the cover on the side of the generator slip rings. The regulator automatically continuously changes the generator excitation current so that the generator voltage is maintained within specified limits when the rotation speed and load current of the generator changes.

Checking the regulator on a car To check, you need a DC voltmeter with a scale of up to 15-30 V, accuracy class not lower than 1.0. Start the engine and let it run for 15 minutes at a crankshaft speed of about min-1 with the headlights on.

At a higher or lower temperature, the voltage may be slightly lower or higher, respectively, by 0.2-0.3 V.

14.8.3 Replacing generator brushes and voltage regulator

Since the warehouse ran out of diode bridges, we had to disconnect the entire bridge in order to press out and replace the broken diode. It is more convenient and easier to press out diodes using a hydraulic press or in a large bench vice, you need to take mandrels to replace the brushes of the Daewoo Matiz generator diode size, or, if you are repairing in your garage and there is no press with mandrels, then you can use the heads from the set for mm and you can use any from 4 to 7 mm, replacing Daewoo Matiz generator brushes, the wire lead freely entered the head, and its walls were wide enough so that the force did not destroy the diode, but was calmly distributed over the surface and when the jaws of the vice were compressed, and the head 13 rested on the radiator plate , and the second, on the other hand, rested on the plastic part of the body.

Removing the generator for Daewoo Matiz

But I put it back together in 15 minutes. This method is for those who do not have a pit. Maybe someone will need it for 6 years Tags: There is not much space there, but it is quite enough to perform this operation. View of the generator from under the hood. Upper bolt of the generator. Next, we remove the engine protection. We unscrew the positive wire from the generator with a key set to “10”.

Removing the chip later is inconvenient and the lock of the chip is not visible. Then, using keys set to “12”, we unscrew the two bolts of the lower hinge of the generator, with the right bolt screwed into the body of the generator from the wheel side, the other bolt is through and locked with a nut.

Bracket for mounting the generator and engine mount We move on to the mounting bracket for the generator. It is secured with three bolts. The top bolt is unscrewed with an elongated head at “12”, the rest can be unscrewed with sockets. We remove the bracket, the generator now hangs on the top bolt.

And I accidentally notice that the generator light blinked, I check the voltage on the battery with a tester upon arrival at the garage - 14.3 volts, ideal. If the value tends to infinity, the circuit is broken.

Check the mobility of the brush carbons in the guides; if necessary, clean the brush holder with grease-removing liquid. There is also an air conditioner tube. I turn out 3 of them, the head is 7 and under the outer one I see traces of burning and burnout of the bushing

On the way to the generator

Next, disconnect the fuel line from the fuel rail. To do this, press two clamps on both sides of the fuel line. Raise the clamps up until they click and lower them back. So, we disconnected the fuel line from the rail.

The generator has one electrical connector that goes to the battery charge indicator light. We will need to disconnect it. A wire (plus) is attached to the nearby nose terminal, which can be disconnected by unscrewing the nut using a 10mm wrench. We need to unscrew the generator tension bolt and two bolts securing the generator bar.

We remove the top bar and monitor the fuel rail, the tube of which can bend if not handled carefully. The generator itself has a bolt and a bracket fastening. To dismantle them, you need to use a 12mm wrench. Next, remove the boot under the generator, which is held on by two nuts with a 10mm head and one bolt.

How to replace the timing belt on a Daewoo Matiz

If you are the owner of a Daewoo Matiz car, then this photo report was prepared especially for you. Here are detailed and clear instructions on how to replace the GPM belt with your own hands.

Now let’s determine what kind of belt you can buy.

If the engine volume of your Matiz is 0.8 liters. then you can buy the following belts for shegov:

Gates 5434XS;
BOSCH 1987 948;
Contitech CT910;
And the cheapest option is Dayco

In principle, the GPM belt does not need to be changed often, but at the same time there is no need to delay replacement until the moment when the belt bursts. The average mileage of a GPM belt is 90,000 km. However, every 30,000 km a continuity wire is required. And if suddenly during the inspection any cracks, creases, traces of oil or tears are discovered, then immediately replace the belt. The only tools we need are a set of standard wrenches and socket heads.

It is also necessary to say about the GPM belt for Daewoo Matiz that if the belt suddenly bursts or breaks while driving, the valves will bend because of this, and the guide bushings will also need to be replaced.

First, we need to remove the top protective cover. This can be done with a ten-point head. You shouldn’t be afraid that everything is very tightly located under the hood, it won’t hinder you in any way, and I don’t think you should have any unnecessary problems.

The next step we will have to remove the top cover, after which we must first loosen and then completely remove the drive belts of the generator, main control unit and air conditioner.

Next we need to remove the right one. front wheel and protective casing, which is located behind the wheel. We also need to unfasten the generator, but since its fastening may oxidize, we first need to loosen the bolt from below.

So now we can get to the bottom of the engine.

Next you need to remove the hanging belts, then you need to set marks on the camshaft pulley.

Now it's up to the generator drive pulley, do you see any risk on it? It should coincide with zero on the GPM housing cover.

Then we need a bolt from the crankshaft and then remove the pulleys using the attachment drive.

To remove the lower belt we need to remove the tube and dipstick. Next, you need to remove the cover; to do this, we unscrew the bolts with a socket wrench with a 10-mm head. We also unscrew the tension roller, after which we remove the timing belt itself.

This is the tension roller and belt we used.

Since our roller is semi-automatic, to install it completely we only have to tighten the bolts, it fixes the roller. You need to tighten it with a force of 15-23 Nm. After tightening the roller and installing the belt, we need to wrap the crankshaft two turns. Make sure the marks match. The mark is located on the lower GPM pulley.

Required tools and materials for DIY replacement

To replace the timing belt on a Daewoo Matiz car with your own hands, you need tools, the list of which is presented in the table below.

We recommend: Changing the oil in the automatic transmission of Volkswagen Polo sedan

Typical generator problems

The vast majority of cars produced by Daewoo have two main types of generating devices. This is a generator Matiz, Nexia CS130 and CS121. A similar model is in Gentra's car. There are no fundamental differences other than the size of the stator. They are even interchangeable.

Unification allows basic repairs to be carried out according to the same scheme, regardless of which model is installed on the Daewoo Matiz. As practice shows, the stator and rotor are both reliable models. In most cases, failure of their operation is caused by mechanical damage.

The most common troubles include:

destruction on the rear cover of the generator bearing;
burnout of the diode bridge due to improper washing, contact with oils and technical liquids on the housing.
scorching of the working surface;
generation of generator brushes.

These problems can lead to others. Thus, the destruction of the bearing leads to strong shock loads on the rotor and stator. Also, because of this, a short circuit of the “plus” of the brushes to ground may occur - and as a result, the relay-regulator will burn out.

Replacing the starter bendix (from Daewoo Matiz) — logbook Geely CK 2008 on DRIVE2

Greetings to everyone! With the onset of cold weather (in the summer, sometimes this sound would occur), when starting the engine, I began to notice an extraneous sound. The sound was precisely when the starter was turned. I went to an electrician, who immediately gave a verdict - replacing the Bendix.

I wanted to have it replaced by the same electrician, but he was always busy... well, we’ll change it ourselves)) I watched a lot of videos about how to remove the starter on a Geely CK. They said that one of the bolts there is very insidiously located and a cardan for the crank (ratchet) is needed. Nothing of the sort, I unscrewed it without any problems using a 16 mm wrench and head.

To remove the starter and replace the bendix you need: - a 8, 10, 13, 16 socket, - a wrench, - a Phillips screwdriver (you can also use a flat head), - a metal brush.

To dismantle the starter, you need to remove the battery, unscrew the three bolts, 10, securing the battery plate. This will give you access to the top starter bolt. The bottom bolt is unscrewed from the pit (photo below).

Starter lower bolt

Before unscrewing the fastening bolts, you need to unscrew the positive terminal of the starter and remove the connector (done from the pit). After this, remove the starter (also from the pit).

After dismantling, on the workbench, you can start getting to the bendix. It doesn't take much work to get to it. I won’t describe it, I’ll share the video I followed.

Of course, I carried out troubleshooting of the armature, brushes and retractor - everything is fine with them (mileage 157,000 km).

Starter on a workbench

Planetary starter mechanism

The most interesting. I went to the store for a new Bendix, but it didn’t fit. It differs both externally and in the internal diameter of the bushing (my Bendix axle did not fit into the hole of the new Bendix). There is a Deu counter nearby. They offered Bendix from Matiz, tried it on - everything fell into place. I bought it from Matiz, what’s more, it’s Korean =))

The sound of the engine starting has changed beyond recognition. Now the engine starts like a full-fledged foreign car))

All the best and smooth roads))

Daewoo Matiz AKPP+A/C › Logbook › Replacing the generator. Hello MANDO BN60273!

Hi all. So the first malfunction occurred in a year and 15 thousand of Matiz’s operation. Well, what about a malfunction... A predictable breakdown, which unfortunately happens to 98% of Matiz owners. Honestly, I was waiting for the demise of the generator, but I had no idea when it would “rest in peace” at the scrap metal yard.

It does not happen that the Generator (Delphi) lives and does not think of dying, it is already 44 thousand km. Gena broke down meanly.

Well, in more detail, it was like this: 3 weeks ago I was getting ready to go on vacation to an all-inclusive place. I moved the car to my parents' yard for the holidays. Fortunately, we live 2 bus stops from each other. I parked the car and flew to warmer climes.

We had a wonderful holiday, quite budget-friendly. Definitely cheaper and much better quality than in our south. Well, not about that now.

I flew home late at night. I immediately went from the airport to pick up Motya. I got into the car, turned the key in the ignition and only heard the sad clicks of the starter. Crap. How is that? In a week Akum. sat down? That's impossible. I couldn’t find an explanation, so I removed the battery and charged it.

Charged and started the engine. All warning lamps have gone out, nothing unnecessary is lit on the instrument panel.

Well, I forgot and forgot about this misunderstanding for 3 days.

3 days later my wife calls me at work:

-Sasha, the car has broken down. I went to the store. First, the charging indicator light flashed, then the wipers slowly began to work and the song no longer played in the car. The battery light is constantly on -Where are you now? - She turned around and somehow miraculously returned home. And having already rolled into the parking lot, Motya stalled. Thanks to him, it didn’t stall on the road, but made it home and even rolled into the parking lot. - Uff, well, at least I don’t have to save you))) I’ll come and sort it out.

What is there to figure out? The topic has been chewed over. Vladimir Trufanov told and showed everything a long time ago Vladimir’s Page

I went online to look at prices for the MANDO BN60273 generator. Prices vary, where they ask for 8 thousand, I found a new one for 4 thousand 590 rubles
