why is hydraulic cylinder drifting
Hydraulic cylinder drift is an issue that occurs between the piston, rod and oil pressure of a cylinder. When a seal breaks and fluid begins to leak, it causes an equalized amount of pressure above and below the piston throughout the cylinder tube. So if you had a failed piston seal on the boom lift cylinder of an excavator with no holding valves, the cylinders would still hold the boom up because the control valve blocks the ports. If you had a boom drifting down noticably, you'd more likely have a problem with a circuit relief valve or anti-cavitation valve in the boom section of the .

Q: Why does my mini excavator make loud noises but fail to start? A: Loud noises without startup generally indicate starter motor issues. Troubleshoot the starter, checking battery charge, electrical connections, starter relay, and motor gear engagement.There are certain conditions in a hydraulic cylinder circuit which may cause a cylinder to slowly drift (creep) when its 4-way control valve is in its center neutral position. The cause (in the fluid circuit) for cylinder drift is the unbalance between areas on opposite sides of the piston. When a hydraulic cylinder exhibits a problem, it is often due to hydraulic drift. Hydraulic drift is can result from internal leaks in piston seals, valves, or rod seals. These leaks can then create unequal pressure that causes the piston to move from its neutral position.
