Shangchai C11al-M8C3651+C Starter Diesel Original Details

Detailed product information

The principle of operation: the electrical energy of the battery is converted into mechanical energy, which is driven by the geneum included in the gear with the gear crown of the engine flywheel, to rotate the crankshaft of the engine and start the engine.

Structural composition: usually consists of three parts: DC engine, transmitting mechanism and control device. DC engine generates the torque after supplying the power; The transmitted mechanism is responsible for turning on and off the drive gear with the gear crown of the flywheel; And the control device controls the turning on and off the starter circuit.

Common types: an ordinary starter, a gearbox starter, etc. The gearbox starter has a gearbox installed between the rotor and the trigger, which can increase the torque transmitted by the starting mechanism. It has characteristics of small size, lightweight and high output power.

The main parameters: including rated voltage, rated power, nominal torque, the number of teeth, etc. For example, a starter suitable for Shangchai has a rated voltage of 24 V, a power of 7.5 kW and the number of teeth 11 teeth.

Stages of installation

Preparation for installation

Check the starter: make sure that there is no damage on the starter’s appearance, all the details are intact, and the drive gear rotates freely.

Prepare tools: Prepare the necessary wrenches, screwdrivers and other tools, as well as materials, such as lubrication that may come in handy.

Clean the details: clean the dust, butter and other garbage around the installation site of the starter and the flywheel of the engine.

Installation process

Install the starter: install the starter exactly to the place where it will be installed on the engine by combining the mounting holes.

Fasten the starter: Use suitable bolts to attach the starter to the engine and tighten the bolts with the specified puffing moment.

Connecting lines: Connect the starter power cable and control line, making sure of the reliability of the connection and good contact.

Adjust the clearance: adjust the gap between the lead gear and the gear crown of the flywheel in accordance with the specified standards, usually 3-5 mm.

Checking after installation

Manual rotation: manually turn the drive gear to check the smoothness of its rotation and the absence of seals.

Checking the power of power: after connecting the battery, check the power on the power to check to check if the starter works fine and whether the drive gear and the gear crown of the flywheel are firmly hooked.

Common errors

The starter does not rotate: perhaps the battery is discharged; The starter wire is weakened or disconnected; The electromagnetic switch failed; The brushes are strongly worn out and have poor contact with the rectifier; The coil of excitement or anchor is closed adversarily or open, etc.

A weak starter: the cause may be the wear of the brushes, a malfunction of the arousal or anchor, aging of the battery and insufficient output current, wear of bearings, leading to an increase in resistance, etc.

The lead gear and the gear crown of the flywheel cannot enter the engagement: this malfunction can be caused by the wear of the gear of the transmission or one -sided coupling, the incorrect installation of the starter, leading to too large or too small a gap between the leading gear and the gear crown of the flywheel, or damage to the gear crown of the flywheel.

The idle stroke of the starter: usually a one -sided coupling slides, the power cannot be effectively transmitted to the engine flywheel, or the gear crown of the flywheel is damaged and cannot normally enter the gear.

The starter continues to work after releasing the starter switch: the contacts of the electromagnetic circuit breaker can count, and the circuit will not have time to turn off.

The most common faults of the Shangchai engine starter include the following categories:

Chain malfunction

The starter does not start:

The problem with the battery: the battery is discharged or the plates are greatly vulcanized and cannot provide sufficient current. For example, if the vehicle has not been used for a long time, the battery will be discharged naturally, which will lead to a low charge level; Or, if the battery has been used for too long, the amount of active material on the plate will decrease, and the internal resistance will increase.

The problem with connecting the line: Starter power line, control line, and other lines are weakened, torn or closed accurately. For example, weakened and oxidized terminal blocks lead to an increase in contact resistance; Damaged wire shells cause short circuits.

A malfunction of the electromagnetic switch: the coil of the electromagnetic switch is open, is closed adversarily or the contacts are burned out, and it cannot be attracted normally, so the starter cannot receive food. For example, the insulating layer of the coil of the electromagnetic switch may grow old and collapse due to prolonged use, which leads to a short circuit of the coil.

The ignition switch malfunction: the internal contact of the ignition switch is bad and cannot accurately transmit the starting signal to the starter control circuit. For example, the ignition switch contacts wear out, which leads to an increase in the contact resistance and a deterioration in the signal transmission.

The starter works weakly:

Deterioration of the battery characteristics: the battery has an insufficient container or electrolyte density is too low, which leads to an unstable output voltage and current. For example, in cold weather, the battery performance will decrease significantly, and the output current will decrease.

The line resistance is too much: the resistance of the power line or grounding line increases, which leads to excessive voltage drop, which is why the starter cannot receive sufficient voltage. For example, the power cord is too long or too thin, or in the middle of the wire there is a connection, which increases the resistance.

The internal malfunction of the starter: the brush is very worn out and has poor contact with the collector; The winding of the excitement or the anchor winding is partially extinguished, which leads to a decrease in the output power of the starter. If the brush is worn to a certain extent, the contact area between the brush and the collector will decrease, and the contact resistance will increase.

Mechanical malfunction

The lead gear and the gear crown of the flywheel are poorly hooked:

The wear of the lead gear: the teeth of the lead gear are strongly worn out, which leads to the impossibility of proper hooking with the gear crown of the flywheel. This can be caused by frequent launches for a long period of time or an excessive collision between the lead gear and the gear crown of the flywheel during the launch.

The gear crown of the flywheel is damaged: the teeth of the gear crown of the tank of the chipped, worn out or cracked, which affects the ending with the sliding gear. For example, if for some reason the engine suddenly stalls during the movement of the car, and the starter will start again without a complete stop, the gear crown of the flywheel can be damaged.

The wrong position of the starter installation: the starter is set in the wrong position, as a result of which the gap between the lead gear and the gear crown of the flywheel is too large or too small, and normal engagement is impossible. For example, fasteners are weakened, which leads to the movement of the starter during operation.

Starter at idle:

Slipping of unilateral adhesion: the video, the spring and other components of one -sided clutch are worn out or damaged, which leads to the fact that it cannot normally transmit the torque normally. When the starter works, the drive gear cannot make the flywheel rotate, which leads to idle. For example, the roller of a one -sided coupling is strongly worn and cannot fit tightly to the inner wall of the case, so the torque cannot be transmitted.

The gearbox for the gearbox for the gearbox is deformed, damaged or stuck and cannot smoothly push the lead gear to hook with the gear crown of the flywheel or cannot return to its position after engagement, which leads to the work of the starter idle. For example, the connecting pin forking of the gearbox is falling off, due to which the gearbox for the gear cannot work properly.

Wear of the internal mechanical parts of the starter:

Bearing wear: bearings inside the starter wear out after prolonged use, causing an abnormal noise when the starter operation and can affect its normal operation. For example, the wear of the bearing balls will increase the resistance to rotation of the bearing or even lead to its stuck.

Detection of the neck of the shaft: wear of the neck of the shaft and the bearing of the starter leads to an increase in the clearance between the neck of the shaft and the bearing, which leads to the vibration of the starter during operation and a decrease in its performance. If the neck is strongly worn out, the starter can work incorrectly.

Other malfunctions

Overheating of the starter:

For too long, continuous launch: repeatedly turning on the starter in a short period of time leads to the fact that the starter has been working too long, secreting too much heat and causing overheating. For example, if the engine is difficult to start, the starter often turns on.

Internal malfunction: problems such as a short circuit of the winding inside the starter and excessive contact resistance between the brush and the collector, will lead to an increase in current, release excess heat and overheating of the starter. If the winding is closed adherently, the current will not pass through the normal load path, but will form a loop directly at the short circuit point, which will lead to a sharp increase in current.

The abnormal noise of the starter:

Friction or collision of mechanical parts: gears, shafts and other parts inside the starter are worn out, weakened or incorrectly installed, which leads to friction or collision between them during operation, which leads to an abnormal noise. For example, uneven wear of the surface of the teeth of the gears will lead to the appearance of abnormal noise during the engagement.

A malfunction of an electromagnetic switch: if an electromagnetic switch is stuck or moves abnormally when closed or released, an abnormal noise will occur. For example, the iron core of the electromagnetic circuit breaker during movement collides with other details.
