All equipment must be in good working condition and be free of defects. All hydraulic lines must be free of leaks. The winch may not leak oil. Cables must be within the specified manufacturer’s guidelines.

When a hydraulic system stops working as intended, whether it is due to a major leak or a failing pump, it can bring productivity to a grinding halt (both literally and figuratively). The process of tracking down the source of the problem involves troubleshooting, which takes considerable skill, experience, and common sense. However, there are some valid guidelines and good hints to help with the process.

The first step in effective troubleshooting is making sure you understand what the problem is — and this can involve asking quite a few questions. If someone says, for example, “The pump is vibrating really bad” then you need to delve a bit deeper with questions, such as:

There are certain problems commonly prevent hydraulic systems from working properly, such as an inoperative system or overheating hydraulic fluid. What follows are some troubleshooting tips for typical issues that arise in hydraulic systems.

If the hydraulic system is inoperative, there are several things that can be checked. Verify the hydraulic fluid levels and keep in mind that leaks can lead to significant loss of hydraulic fluid. Take a look at the hydraulic filters, because if they are dirty or clogged badly enough, it can seriously impact performance. Check for restrictions in the hydraulic lines; restrictions often take the form of a collapsed or clogged line.

Make sure there are no air leaks in the pump suction line. Also inspect the pump itself; if it is worn, dirty, or out of alignment, it will affect system performance. The pump drive can be a source of issues if it the belts or couplings are slipping or broken. It may be time to replace some components; as they begin to wear, it can lead to internal leakage. It is also a good idea to make sure that the unit is operating within its maximum load limits.

When a hydraulic system begins working more slowly than normal, one of the causes can be hydraulic fluid that is too thick, which may be due to cold temperatures or the use of an

If the system is operating in an erratic, unpredictable manner, the most common causes are air trapped in the system, hydraulic fluid that is too cold (which means the equipment needs an opportunity to warm up before use), and damaged internal components such as bearings and gears.

Another common issue with hydraulic systems is excessive/abnormal noise or vibration. If it is the pump that is noisy, then check that the oil level is sufficient, the correct type of fluid is being used, and that the oil is not foamy. If the oil is foamy, that points to air in the fluid which can lead to cavitation and expensive damage. It is also wise to verify that the inlet screen and suction line are not plugged. For both pumps and hydraulic motors, there can also be internal issues, namely worn or misaligned bearings. And do not forget to make sure that the couplings are secure and tight. Keep in mind that pipes and pipe clamps can vibrate if they are not secured properly.

Excessive heat is never a good sign in a hydraulic system and often leads to a system working at sub-optimal levels. One of the purposes of hydraulic fluid is to dissipate generated heat, but the system should not be generating enough heat to cause the fluid to reach high temperatures.

There can be a host of causes behind hot hydraulic fluid, starting with contaminated hydraulic fluid or fluid levels that are too low. There may be oil passing through the relief valve for too long at a time; in this case, the control valve should be set to neutral when it is not in use. Worn out components within the system can also lead to excessive temperatures due to internal leakage.

If there are restrictions in the line or dirty filters, hot hydraulic fluid will result. If hydraulic fluid viscosity is too low, it can lead to overheating as well. Finally, there may be a need to make sure that the oil cooler is functioning correctly and that the key components are clean enough for heat to radiate away from them.

We have discussed low viscosity as a symptom, but it also qualifies as its own problem. When trying to determine why the fluid is not as viscous as it should be, the three things that need to be checked are damage to the oil (often from extreme temperatures or aging), use of the wrong type of hydraulic oil, or the presence of water in the hydraulic fluid. In all three cases, the system will need to be flushed and the oil replaced.

Having no flow within the hydraulic system is a serious issue that can have several different sources. The first step is to determine exactly where the fluid flow stops, such as failure of the pump to receive fluid at the inlet (usually the result of a clogged line or dirty strainers) or a failure for fluid to exit the outlet, which could be due to a pump motor that needs replacing, a sheared coupling between the pump and drive, or a pump/drive failure. It would also be a good idea to make sure the pump rotation is set correctly and the directional valves are in the correct position. The most expensive problem would be a damaged pump that needs to be replaced or repaired.

The first step in troubleshooting is to gather as much information about the problem as possible and then pull the hydraulic schematics for the system. From there, you basically follow a process of elimination until the root of the problem is uncovered. Something else to keep in mind with regard to troubleshooting, however, is that once you have tracked down the source of a problem, it may lead you to yet another problem that will need some troubleshooting. Getting your hydraulic system back in working order can be a time consuming process.

For example, you may uncover that the cause of overheating hydraulic fluid is low viscosity — but why is the fluid insufficiently viscous? The troubleshooting process is not over until that issue is uncovered. Take, as another example, the case of a pump whose internal components have worn out and affected overall system performance — why did the components prematurely wear? It may be a cause of misalignment, insufficient lubrication, or contaminated fluid. A good hydraulics technician will not just track down and address the problem, but will keep troubleshooting to make sure that the problem does not happen again.
