What are the symptoms of the broken oil pump?
Once the oil pump is damaged, the oil pressure cannot be established, resulting in poor lubrication of the engine, which will not only affect the power performance and fuel economy of the whole vehicle, but also aggravate the degree of wear of the engine, which may easily lead to slip or even direct scrapping. Therefore, we must pay attention to the damage of the oil pump. If the above symptoms occur and the oil alarm light is still on, we need to check whether the oil pump is abnormal.
Causes of oil pump damage:
Use engine oil with poor quality or wrong model. Good engine oil can prolong the maintenance period properly. Poor quality engine oil will only accelerate engine wear, causing abnormal noise and mechanical damage. At the same time, due to climate reasons, when selecting oil products in different places, attention should be paid to the meaning of the model and the low temperature resistance and viscosity of the oil.
Clogged oil filter will also cause the oil pump supply pressure to increase. Working under such high load for a long time will cause accelerated deterioration of the oil pump.
The drop of oil level will reduce the heat dissipation effect of the oil pump, and "dry pumping" will lead to serious heating and damage of the lines in the oil.
The oil pump for the ride is usually installed in the right crankcase body, and can only be seen by removing the magnetic motor, the right cover of the crankcase, etc. The oil pump usually rarely malfunctions.
How to install the camshaft on a motorcycle requires removing the cylinder head, cylinder block, magneto side cover, and magneto to replace it. Moreover, the camshaft and timing teeth need to be replaced simultaneously, and the crankshaft timing teeth also involve special tools and alignment.
If the shift fork is damaged, it may cause gear loss, jumping, and difficulty changing gears; Due to damage to the shift fork, the transmission is unable to shift the synchronizer to the engaged position, resulting in the synchronizer not being able to mesh perfectly with the engagement sleeve.
The gears inside the motorcycle gearbox are not easily damaged, and once damaged, the main manifestations are the following
The filter accuracy of oil filter is within 10 μ～ fifteen μ Its function is to remove impurities in the oil and protect the normal operation of the bearing and rotor. If the oil filter is blocked, it may cause insufficient fuel injection, affect the service life of the main engine bearing, increase the exhaust temperature of the engine head or even shut down.
