The starter consists of a drive part, a housing with poles and a collector part. The pole and collector parts contain an armature, a collector and a brush holder. Carbon brushes wear out over time. With severe wear of the brushes, the starter may fail.
A gear train is located in the drive part of the housing. After the ignition is turned on, the starter is powered by the battery. By means of a magnetic starter located in the starter housing, its gear engages with the ring gear of the engine flywheel. After that, the engine can be started. After starting the engine, the starter spins in the opposite direction by the engine and the connection between the starter and it is terminated.
It takes a lot of current to start the motor. Therefore, in the process of maintenance, it is necessary to pay special attention to the quality of the connections. Corrosion in the wire connection is not allowed. To do this, it is necessary to cover the contacts with protective grease.
Depending on the type of engine, COROLLA has starters of various capacities: petrol engines have a starter of 0.8-/1.0 kW, diesel engines - 1.4-/2.0-/2.5 kW.
Attention: Depending on the type, the starter may be a replaceable part. This means that when buying a repaired or new starter, the old starter can be returned and its cost will be taken into account when paying.
