Remove the starter Lada Largus 16 valves K4M engine

A starter or starting device (PU), as it is sometimes called among motorists, is designed to start a car engine. After turning the key in the ignition switch, current is transferred from the battery to the control unit. The latter is activated, driving the motor.

Violation of the rules for using the mechanism leads to its rapid wear and damage. For example, keeping it in an active state for more than 15 seconds wears out the bendix teeth and increases the operating temperature on the rubbing surfaces.

The design of the starting device is quite complex, despite the intuitive operating principle. We do not recommend carrying out repairs without experience in servicing equipment.

How to remove the starter of a Lada Largus car

Place the car on a lift or inspection hole.
Disconnect the negative terminal of the battery.

Using a flat-head screwdriver, press the fasteners and remove the casing (if installed) of the electronic control unit (ECM).

Using a 10mm wrench, unscrew the two nuts 1 securing the expansion tank 2.

We remove and move the expansion tank to the side without disconnecting the hoses.

If a JR5 gearbox is installed, use a flat screwdriver to disconnect joints 1, selector and shift cables from the gearbox.

We press the clamps and disconnect the stoppers of the sheaths of the gear selection and shift cables from the gearbox bracket.

If JH3 gearbox is installed:

Remove the cover 1 of the gearshift drive rod joint. Using a 10mm wrench, unscrew bolt 2 securing the gearshift drive rod, remove the spacer bushing and disconnect the rod.

Using a 13mm head, unscrew the three bolts 1 securing the starter

If the car is installed on a lift, then we lift the car to perform work from below.

Using a 13mm socket, unscrew nut 2 securing bracket 4 to intake manifold 3.

Using a 17mm head, unscrew bolt 6 securing bracket 4 to cylinder block 5.

Remove bracket 4 for fastening intake manifold 3.

Use a 10mm socket to unscrew nut 2

Disconnect harness 1 of the ignition system wires from starter 3

Using a 10mm socket, unscrew nut 4 securing the starter wires 5.

Disconnect the starter wire.

Using a socket 8, unscrew nut 3 securing the starter electromagnetic relay wire 5

Starter installation

Install the starter in the reverse order of removal.

In this case, the tightening torques of threaded connections:

— starter mounting bolt — 44 Nm (4.4 kgf.m);

— starter wire fastening nut — 8 Nm (0.8 kgf.m);

— nut securing the starter electromagnetic relay wire — 5 Nm (0.5 kgf.m);

— bolt for fastening the gearshift drive rod — 27.5 Nm (2.75 kgf.m).

We connect the terminals to the battery.

Problems when paying with bank cards

Sometimes difficulties may arise when paying with Visa/MasterCard bank cards. The most common of them:

1. There is a restriction on the card for paying for online purchases
2. A plastic card is not intended for making payments online.
3. The plastic card is not activated for making payments online.
4. There are not enough funds on the plastic card.

In order to solve these problems, you need to call or write to the technical support of the bank where you are served. Bank specialists will help you resolve them and make payments.

That's basically it. The entire process of paying for a book in PDF format on car repair on our website takes 1-2 minutes.

Removing and checking the Lada Largus starter

We remove the starter to repair or replace it, as well as when dismantling the engine and gearbox.

We carry out the work on an inspection ditch or overpass.

We show the operations for removing the starter on a car with an engine

1.6 (16V). By car with engine

1.6 (8V) starter is removed in the same way. Disconnect the wire terminal from the negative terminal of the battery.

We remove the power unit protection (see “Removing the power unit protection”, p. 235).

Using a high “8” socket, unscrew the nut (the nut is attached to the tip of the wire).

Use a 13mm socket (without an extension) to unscrew the lower starter mounting bolt.

Use a screwdriver to move the drive gear along the shaft.

The gear should move easily along the shaft without jamming. If the gear sticks on the shaft, the drive must be replaced.

To check the starter, we connect the “positive” terminal of the battery to the upper contact bolt of the traction relay with wires for “lighting”, and the “negative” terminal to the starter housing.

TECHNICAL CHARACTERISTICS OF STARTERS

The starter is a DC motor that can produce quite a lot of power for its size. One of the things that allows this engine to produce more power is that it has a higher rotation speed. It drives the engine through a small gear included in the starter hardware, which turns a large gear (flywheel) at a greatly reduced speed. Another factor that allows it to achieve more power is that it operates in intermittent mode, i.e. only at startup. This way the starter has little need for air circulation and the windings can be contained in a small space.

Starter solenoid

The starter solenoid is a magnetic device that uses a small current supplied to the starter energizing circuit from the ignition switch. This magnet, when in operation, moves a plunger that mechanically engages with the starter and electrically shorts the thick wire that connects the starter to the battery. The starter activation circuit consists of the starter switch, located in the ignition switch, and wires to connect them to the starter solenoid or relay.

The gear, which serves to transmit rotation, is mounted on a one-way clutch. This coupling is mounted on splines on the starter armature shaft. When the ignition key is turned to the start position, the solenoid plunger drives the gear to the flywheel ring gear through the ring and spring. If the teeth of the gear and flywheel match exactly, the gear will immediately engage the flywheel. If a tooth engages another, the spring will be compressed and act on the teeth to keep them engaged while the starter turns. As the solenoid reaches the end of its stroke, it closes the contact between the battery and the starter, and then the engine is cranked by the starter.

As soon as the engine starts, the flywheel wheel begins to spin faster than the gear spins at its highest rotation speed. In this case, the one-way clutch (Bendix) begins to allow the gear to rotate faster than the starter shaft, so the starter will not operate at increased speed. When the ignition key is removed from the “start” position, the solenoid is de-energized and the spring located inside the solenoid forces the gear out of mesh, and the current supply to the starter is stopped.

There is a spring between the gear and the drive arm from the start relay so that if the teeth are misaligned and the gear is encouraged to engage the flywheel ring, the solenoid continues to operate and provides voltage. The gear will immediately engage as soon as the starter shaft begins to rotate.

How to remove the starter on LADA cars with your own hands

The starter is removed in connection with its replacement, inspection or repair. On LADA cars, the starter is installed on the clutch housing at the front in the direction of travel. Before starting work, you should disconnect the negative terminal of the battery, drive the car onto an inspection ditch (overpass) and remove the engine protection.

On all modern LADA cars (Lada XRAY, Vesta, Largus, Granta, Kalina, Priora and Niva 4x4), removing the starter is performed in the same way. Installation is carried out in reverse order. Distinctive features of the process are presented below.
