The starter motor for Renault Duster is a four-pole, four-brush DC motor with permanent magnet excitation, combined with an electromagnetic two-winding traction relay

Covers and stator housing are tightened with two bolts. Permanent magnets are fixed in the stator housing.

Rotation from the shaft of the electric motor armature is transmitted to the drive gear through the freewheel clutch.

When the key is turned in the ignition switch to the "D" (engine start) position, the battery voltage is applied to the retractor and retaining windings of the traction relay, as a result the drive lever moves and the starter gear engages with the engine flywheel toothed rim.

At the same time, the armature of the traction relay closes the power contacts (at this moment, the retracting winding is turned off) and the voltage from the battery is supplied to the starter motor.

The starter armature turns the engine crankshaft through the freewheel clutch.

After starting the engine, when the speed of the gear wheel exceeds the speed of the starter shaft, the freewheel is unlocked and slips, protecting the starter from high speed and damage.

Use a screwdriver to turn the drive gear. The gear should turn in one direction with the drive shaft, and in the other direction on the drive shaft. Otherwise, the drive must be replaced.

Use a screwdriver to move the drive gear along the shaft. The gear should move easily along the shaft without jamming.

To check the starter, we connect with wires: the positive terminal of the battery with the upper contact bolt 1 of the traction relay, and the negative terminal with the starter housing.

Use a screwdriver to bridge the upper contact bolt 1 and control terminal 3 of the traction relay.

At the same time, the drive gear should move out and the starter motor will turn on. Otherwise, we check the electric motor and the starter traction relay.

To check the electric motor, we connect the wires to the positive terminal of the battery with the lower contact bolt 2 of the traction relay, and the negative terminal to the starter housing.

In this case, the shaft of the electric motor must rotate.

Otherwise, the motor is defective.

To check the traction relay, we connect the wires to the positive terminal of the battery with the control terminal 3 of the traction relay, and the negative terminal to the starter housing.

In this case, the drive gear should move out.

If this does not happen, the traction relay is faulty.

Install the starter in reverse order.

Use a screwdriver to move the gear along the shaft. The gear should move easily along the shaft without jamming.

If the gear sticks to the shaft, the drive must be replaced.

To check the starter, we connect with wires: the positive terminal of the battery with the upper contact bolt of the traction relay, and the negative terminal with the starter housing.

With a screwdriver, we bridge the upper contact bolt and the control output of the traction relay.

At the same time, the drive gear should move out and the starter motor will turn on.

To check the traction relay, we connect the positive wire of the battery to the control output of the traction relay, and the negative output to the case.

In this case, the drive gear should move out. If this does not happen, the traction relay is faulty.

When installing the starter, first we put the wire ends on the contact bolt and the control output of the traction relay and tighten the nuts of their fastening.

We install the starter in place and attach three bolts of its fastening.

The locating sleeve 1 in the clutch housing must enter the hole 2 of the front starter cover.

After that, we finally tighten the starter mounting bolts and the nuts for fastening the wire ends.

We inspect and check the condition of the collector and armature windings.

Charring of the windings is not permitted.

The ends of the windings must be well soldered to the collector lamellas.

If the collector is slightly burned, we clean its plates with a fine abrasive cloth.

With an ohmmeter, we check the short circuit of the armature winding to ground.

The resistance should be very large (strive to infinity).

We replace the defective anchor.

We inspect the brushes; they should not have cracks or chips. Otherwise, replace the brush holder with a new one.
