hi can anyone help I have a cat 301.5 excavator. when you swing around it will not stop and seems to be under power still. how do I fix it.
If it is still under power then spool in control valve must be hanging up. Is this a pilot system? Does it do this in both directions?
Is this something that has just started, or have you recently bought the machine and it has always been like that since you got it..? Does it stop if you try to swing in the opposite direction..? Have you tried it with the machine on perfectly level ground..?
