Starter Motor Solenoid Valve Check And Change

The starter motor solenoid valve in heavy equipment is one of the critical components. It plays a vital role in the start-up process of the machine. However, due to long-term use or other factors, the starter motor solenoid valve may fail. Causing heavy equipment to fail to start properly. In this article, MyMROmarts will introduce the definition, check method, and change procedure of the starter motor solenoid valve. Helps readers understand how to maintain and repair starter motor solenoid valves.

What Is A Starter Motor Solenoid

The start motor solenoid valve is usually used to control the start and stop of the starter motor. In heavy equipment, starter motor solenoid valves play a key role in automation control. It realizes the conversion of control signals through electromagnetic principles and converts electrical signals into mechanical actions. This enables the starting and stopping of heavy equipment.

How To Check A Starter Motor Solenoid

a. Always disconnect power to the heavy equipment where the starter motor solenoid is located before performing any inspections to ensure safe operation.

b. Carefully observe the appearance of the starter motor solenoid valve for obvious damage, corrosion, or deformation.

c. Remove dust, oil, and other dirt around the solenoid valve of the starter motor to ensure its surface is clean.

d. Check the connection of the solenoid valve of the diesel engine starter motor. Including whether the wiring terminals are firm and whether the wiring is connected correctly.

e. Set the multimeter to an appropriate measurement range, and connect its electrodes to the terminals of the solenoid valve of the starter motor to test the insulation resistance and coil resistance of the solenoid valve.

f. Using an appropriate test instrument, check that the operating voltage of the starter motor solenoid valve is within the rated range.

How To Change A Starter Motor Solenoid

a. Before changing the starter motor solenoid valve, make sure to disconnect the power supply and drain the hydraulic or air pressure in the machine.

b. Carefully remove the housing of the starter motor solenoid valve, taking care not to damage other components.

c. Before removing the solenoid valve of the starter motor, it is necessary to take pictures or record the position of the connecting line so that it can be connected correctly after the change.

d. Carefully remove the old starter motor solenoid, making sure not to damage surrounding components.

e. Install the new starter motor solenoid valve correctly in place and make sure that the wiring is correct.

f. After power is restored, perform the starter motor solenoid valve test. Verify that it is working properly, making sure the machine starts and stops properly. Only in this way can the starter motor be able to drive other diesel engine parts to work normally.

g. After the change, clean the dirt around the solenoid valve of the starter motor and perform regular maintenance to prolong its service life.

Starter motor solenoid valves play an important role in heavy equipment. Not only the starter motor solenoid valve, but the diesel solenoid valve also plays an important role in heavy equipment. The diesel solenoid valve opens or closes the fuel flow according to the control signal. Thereby controlling the operation and flameout of the engine. Reasonably check and change the solenoid valve in time. This helps ensure the proper functioning and longevity of heavy equipment.
