The Yanmar 97120951 starter motor is a key starting device specially designed for Yanmar engines. It can convert the electrical energy of the battery into mechanical energy, quickly start the engine by driving the engine flywheel, and ensure the smooth operation of the equipment.
We sell genuine original starter motors that match this model, ensuring perfect compatibility and optimal performance with your Yanmar engine. At the same time, we also understand the needs of customers under different budgets, and therefore offer quality-verified aftermarket parts for selection. These aftermarket parts can effectively reduce costs while ensuring reliability.
Detailed product description
Core role and importance
The Yanmar 97120951 starter motor is the "starting point" of the engine. Its reliability is directly related to whether the entire equipment can start up and work normally. A high-performance starter motor can ensure that the engine starts quickly and smoothly, reduce the energy consumption of the battery, and lower the wear and tear on other related components.
Maintenance and care suggestions
Proper maintenance can significantly extend the service life of the starter motor. Please pay attention to the following key points:
Regular cleaning: Regularly use compressed air (pressure is recommended to be ≤0.5MPa) to blow off the dust and oil stains on the motor surface, especially at the heat dissipation holes and terminal blocks, to prevent impurities from affecting heat dissipation and electrical conductivity. For stubborn oil stains, you can wipe them with a cloth dipped in diesel or neutral detergent. Do not directly use a high-pressure water gun to rinse to prevent water from entering the interior.
Inspection and maintenance of key components
Brushes and commutators: Regularly check the length of the brushes. If they are worn to one-third of their original length (or remain about 5-8mm) or have cracks or fallen blocks, they should be replaced in a timely manner. Check whether there is oxidation or ablation on the surface of the commutator. If necessary, gently sand it with fine sandpaper (400-600 mesh), and ensure that the contact area between the brush and the commutator is greater than 70%.
Bearings and Lubrication: Regularly apply appropriate grease to the front and rear bearings (or bushings) (high-temperature lithium-based grease is commonly used for rolling bearings, and special motor lubricating oil can be used for sliding bushings). If you shake the rotor shaft by hand and feel that the radial movement exceeds 0.5mm or there is an abnormal noise during operation, you should consider replacing the bearing.
Electromagnetic switch: Check whether the contacts are oxidized or burned. If they are severely worn (with a thickness less than 1mm), they need to be replaced.
Electrical connection inspection: Regularly tighten the terminal blocks of power lines and control lines to prevent excessive contact resistance and overheating due to loosening caused by vibration. Check whether the insulation layer of the cable is intact.
Operating habits
The single start-up time should not exceed 10 seconds. If the startup fails, wait for more than 30 seconds before attempting again to prevent the motor from overheating
Avoid restarting the starter motor when the engine is running.
Storage Instructions: If the equipment is to be idle for a long time, it is recommended to disconnect the power cord of the starter motor and place a thin paper sheet between the brush and the commutator to prevent oxidation. The storage environment should be dry and well-ventilated.
Frequently Asked Questions (FAQ
Q: What should I do if I make a "tap-tap" sound when starting the motor but can't drive the engine?
A: This is usually caused by the erosion of the electromagnetic switch contacts or insufficient battery power. Please first check the battery voltage and wiring. If the problem persists, it may be necessary to repair or replace the electromagnetic switch.
Q: What could be the reasons for the weak starting speed of the motor?
Possible causes include: excessive wear of brushes leading to poor contact, poor lubrication or wear of bearings resulting in excessive resistance, insufficient battery power or corrosion of cable joints causing A drop in supply voltage, as well as internal winding faults.
Q: Is it difficult to start the motor in a low-temperature environment?
At low temperatures, the viscosity of the engine oil increases, and the capacity of the battery also decreases, resulting in increased starting resistance and insufficient starting speed. It is crucial to ensure the use of engine oil of the appropriate viscosity and to keep the battery fully charged. For equipment that is used for a long time in extremely cold regions, it is advisable to consider installing some auxiliary starting devices.
