If the actual starting motor is burned out, it is impossible to start the car with the starter motor. Shift to first gear and press the clutch to start the emergency engine. Manual transmission: The vehicle can be started in first or second gear, with first gear engaged and clutch engaged, but requires someone to push or tow the vehicle. When the speed increases, lift the clutch and the vehicle can start. We should handle or maintain the starter motor as soon as we discover any abnormalities. Here are some examples of starting abnormalities and how to handle maintenance situations.
1:Fault of slow starting speed or inability to drive the engine crankshaft.
Turn on the front headlights or horns, observe whether the brightness of the lights and the sound of the horns are normal, and also measure whether the voltage of the battery is normal. If it weakens, check whether the battery is low and whether the wiring connection is loose.
If the headlights or horns are found to be weak, it can be determined that the battery is in a low battery state (voltage can be measured with an instrument if conditions permit). The low battery state can be solved by charging, and the storage capacity of the battery and the power generation of the alternator need to be checked to ensure they are normal. We need to deal with the stains on the battery terminals and tighten them before using them.
The above two issues are normal, and we need to remove the starter for maintenance and cleaning.

2: Handling of starter not running under normal power supply.
Check if the electromagnetic switch is properly engaged, if there is any jamming problem with the one-way switch, if there is a short circuit inside the motor, and if the brush is in good contact due to wear.
3: The starter makes a harsh sound when starting and cannot start the engine.
Check the engagement between the starter one-way drive and the engine flywheel. If the engagement is abnormal, adjust the distance between the one-way drive and the flywheel. Check for burrs and short teeth between the one-way drive and the flywheel, and check for good engagement of the starter switch.
If the engagement between the starter one-way drive and the engine flywheel is normal, it is necessary to check whether the starter one-way drive is slipping and whether there is tooth breakage in the reduction gear of the starter. Check whether the shaft sleeves or bearings of various parts of the starter are normal.
The above is just a brief description of several common faults in the starter motor. If your problem still cannot be solved, you can contact us to study and solve it together.
For example, in our case, the PC200-6 excavator, after using our 228000-4992 (S6D102) starter engine for 2 years, suddenly found that it started well when the engine was cold, but could not start when the engine was hot. This issue was reported to the technical department and analyzed to be completely opposite to the theoretical normal situation. It is highly likely that this issue is not related to the starter motor. However, the company's mission is to serve every customer well, sending technicians on business trips to solve problems on site. We often discuss and detect that it is due to a hydraulic system malfunction of the excavator, which causes slow pressure relief after the excavator stops. When the engine starts, the pressure brought by the hydraulic system causes the starter speed to be low and the engine cannot be started. After repairing the hydraulic system, this problem was perfectly resolved.
Our company has many years of development and production experience, as well as a strong technical team. No matter if you have any problems during the use of starters or generators, please feel free to contact us at any time and we will provide you with the perfect solution.
