Why is my excavator swing motor not working?
Why is my excavator swing motor not working?
If you have not checked pressure, I would install a gauge at the brake line on the swing motor to see if it is loosing pressure while operating. If this machine is having charging problems, low voltage can cause the solenoid to not stay released. High voltages can cause the ecm to shutdown and lock all the controls.
What causes a travel motor to be weak?
One major cause behind a weak final drive or travel motor is simply a lack of hydraulic pressure. This can be detected by checking the hydraulic pressure at the final drive. You can refer to your manufacturer’s guidelines for the expected pressure reading you should obtain. The second potential cause behind a lack of power is high friction.
What should I do if my starter motor won’t turn?
It should turn in one direction only; check the gear teeth for wear and damage. Or take the starter motor to your local auto parts store. They can bench test the starter for you without charge. If the starter motor turns out fine, check the flywheel for missing teeth or damage to the ring gear or similar problems.
Why does my travel motor make a screeching noise?
Check the speed control system before you send in your travel motor for repairs or inspection. If your final drive is making a screeching noise along with a lack of power, the problem is most likely the charge pump.
How does an excavator swing motor work?
Piston pumps that form the oil pressure using engine power and main control valves convey the oil pressure to each part. Swing motors are hydraulic motors that form the proper turning force of excavator booms using oil pressure, shift rotation either to the right or left and convey or cut off turning power.
What kind of motor doesn’t work in the wrong direction?
Examples include HVAC unit blower squirrel cage fans whose blades won’t move air if the fan runs backwards and oil burner or well pump motors whose oil pump or water pump won’t move oil or water if the pump motor is driven in the “wrong” direction.
Why does the motor keep turning after the winding is turned off?
Current flowing through this winding produces a rotating magnetic field in the stator that keeps the motor shaft turning after the start winding has turned off.
Is it possible to change the direction of an electric motor?
Manually-reversible Electric Motor Run Direction. By swapping wire connections on some electric motors it is possible to change or reverse the motor direction. Typically purple and yellow wires or wire pairs permit this change.

How to turn off the fine swing control on an excavator?
Push down on the left side of the switch in order to turn off the fine swing control. Operate the machine with the switch in the OFF position when great swing forces are required. For example, digging on a sidewall requires great swing force.
What causes a cat 320 engine to overheat?
Hopefully coolant is no more than 50% glycol, don’t overlook this as too high a concentration can result in overheating. Another rogue for engines heating up is fuel timing, hopefully your dealer will have spill timed the engine to ensure its set up properly.
