Why does my excavator not swing in either direction?

Why does my excavator not swing in either direction?

The rear solenoid had no power on either wire. At full throttle on right console left switch down and right switch held up lights flash on panel, while doing this moving the swing lever in either direction I can feel it bump each time the lights flash. The machine still does not swing. Any suggestions? I did miss a step for you to test.

Why is my excavator not getting power from the ECM?

If no voltage is present then the K907 green wire on the back-up switch is not getting power from the ECM. The ECM is bolted under the seat. It should have a green light showing when the key is on. Inspect the wiring from the back up switch to the ECM. If no problems are found, unbolt the ECM and inspect the bottom for corrosion.

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.

When to use the swing brake on an excavator?

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. Operate the machine with the switch in the OFF position in order to control the motion with the swing brake. The purple wire gets voltage from the fine swing fuse.

Where are the solenoids on a 322bl excavator?

A K906 green wire is the control from the ECM, this wire runs through the back-up mode switch (K907 green) located in the rear of the right hand console. This switch can be placed in back-up mode to test the solenoid also. Try it in back-up and see if brake releases. Your model should have two solenoids.

What do you need to know about swing repeat?

On the downswing, it’s all about my left hip—actually, the left knee, thigh and hip. I want to feel them clearing out, or turning to my left, so my right side can drive hard.

Why does a Caterpillar excavator have a hydraulic fan?

The high-efficiency hydraulic fan cools the engine on demand to help reduce fuel consumption; an optional reverse function enables you to clean cores quickly. The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.

Why does my cat spin in opposite directions?

When you run both tracks in opposite directions it will spin but very slowly. It does seem stronger when the oil is cold and gets weaker as it warms up. All other hydraulic functions seem to be ok, the machine digs fine.

Why are the tracks on my Cat 320n not turning?

The smallest line running through the swivel will be the one to the travel motor speed actuators. You could try to plug it and see if anything changes. If the battery voltage dropped low enough, the solenoid valve for the two speed might drop out. Maybe it’s an electrical problem…..
