DIY Chevrolet Lacetti starter repair

In detail: do-it-yourself repair of a chevrolet lacetti starter from a real master for the site my.housecope.com.

We repair the starter of the Chevrolet Lacetti car. The starter has a broken bendix, and there was no contact on the brush assembly. This was manifested in the fact that the starter was turning, the starter was humming with no load, the car would not start.

We disassemble and repair the Chevrolet Lacetti starter.

The main illness of the Chevrolet Lacetti starter is that the breather is not made in it, as a result of the resulting condensate does not drain away, corrosion appears that affects all the main starter units, the brushes, for example, reach such a state that they wedge in the glasses of the brush assembly.

In the video, you can see the solution to this problem, drilling a hole with a diameter of about 3 mm in the lower part in order for the accumulated condensate to drain. It really helps!

As we can see, with a great desire and opportunity, you can easily disassemble, repair the starter on the Chevrolet Lacetti with your own hands, there are no particular difficulties in this.

We remove the starter for repair or replacement if it fails, as well as when dismantling the engine.

When the engine refuses to crank after applying voltage and turning the key, it becomes clear that either the contacts or the battery are to blame, or you need to think about how to remove the starter on the Chevrolet Lacetti. This is the only way to diagnose and repair it. As a last resort, replace.

Two starter mounting bolts

The starter is attached to the cylinder block on the right on two studs, but in order to dismantle it, you must disconnect all the wiring that belongs to it.

The work on the removal of the unit is carried out either on inspection pit, or on a lift and it won't take long. For its implementation, only a standard set of tools will be needed; in extreme cases, an aerosol penetrating lubricant of any manufacturer can be useful.

It is advisable to process the nuts and studs with it in advance. We carry out the work in the following order:

    We install the car on a lift or inspection pit, overpass.

Dismantle the starter power wire.

Here is the power to the solenoid relay.

Old and new starter Magnetti Morelli

After repairing or replacing a starter with a new one, several important rules must be observed:

  • the tightening torques of the nuts on the studs in 1.4 and 1.6 liter motors must be at least 23 Nm;
  • for engines with a volume of 1.8 liters, the tightening torque of the fastening screw to the cylinder block is 45 Nm, and to the gearbox - 50 Nm;
  • tighten the nuts of the solenoid relay terminal with a torque of 5.5 Nm;
  • the tightening torque of the cable nut from the ignition relay is the same, 5.5 Nm;
  • We twist the large negative cable with a torque of about 12 Nm for confident contact.

Using this algorithm and tips, you can quickly replace the starter on the Chevrolet Lacetti with your own hands. Successful work to all and good roads!

Starter not working - troubleshooting
To do the work, you will need an assistant, a multimeter,
Sequence of execution
1. We check the fuse-link Ef4 of the mounting block of fuses and relays. We replace it if necessary. We are trying to start the engine. If the fuse link burns out again, there is a short circuit in the wiring that must be repaired. When searching for a short circuit, we use the electrical diagrams given in the appendix.
2. Check if the battery is charged. We charge it if necessary.
3. Check the connection of the wires to the starter terminals. If necessary, we clean the contacts and treat them with a special conductive grease.
4. Checking the starter.
5. We check the electrical circuit of the starter.

Starter check
You can check the electrical part of the starter without disassembling it.
1. Remove the starter.

When checking, do not short-circuit the positive battery terminal to the starter housing.

2. Connect the negative terminal of the storage battery to the starter housing with one wire. The second wire, connected to the positive terminal of the battery, is connected to the contact bolt 3 of the retractor relay, to which the starter wire is connected. If the starter armature starts to rotate, the starter motor is operational. Otherwise, the brush assembly or anchor is faulty.

3. We connect the wire connected to the positive terminal of the storage battery, to the terminal bolt 1 of the retractor relay. Using a screwdriver or other suitable metal object, we short-circuit terminal 2 and the terminal bolt 1 of the solenoid relay. If there is a loud click and the starter armature begins to rotate, the retractor relay is working properly. If the relay has tripped, and the starter motor has not started to rotate, then most likely the contacts of the solenoid relay burned out and they must be cleaned, for which the relay must be removed. If the relay does not work, it must be replaced.

4. When the solenoid relay is activated, the drive should move along the starter shaft. If this does not happen, the drive lever is faulty. Contact a specialist workshop for repair.

5. To check the overrunning drive clutch with a screwdriver, rotate the gear in different directions. In this case, the gear must rotate in one direction with the shaft, and in the other direction separately from it (the shaft remains stationary). Otherwise, the drive must be replaced. To replace the drive it is necessary to disassemble the starter.

Removal and installation of a starter
The starter is secured with two bolts on the right side of the cylinder block at its rear.
To complete the work, you will need an inspection pit or overpass.

Withdrawal
1. Preparing the car for the job.

2. With a 13 mm wrench, unscrew the nut for securing the "mass" wires, remove the wires from the stud, unscrew two studs for securing the starter (the second is located symmetrically on the other side of the starter), disengage the starter from the flywheel and turn it down with the rear part for easy unscrewing of the fastening nuts wires.

3. Using a 13 mm wrench, unscrew the nut securing the wire to terminal B + of the retractor relay and remove the wire.

4. Using a 10 mm wrench, unscrew the nut securing the wire to the "ST" terminal of the retractor relay, remove the wire and remove the starter.

Installation
Install the starter in reverse order.
