![]() ![]() Fluid temperature is too high when viscosity falls below the optimum value for the system’s components. This means that the operation of any hydraulic system at temperatures above 180☏ is detrimental and should be avoided. Flexible intake lines are prone to collapsing with age therefore, replace old or suspect intake lines.įluid temperatures above 180☏ (82☌) can damage seals and accelerate degradation of the fluid. The intake line between the reservoir and pump should not be restricted. This type of isolation device is prone to vibrating closed. If a gate-type isolation valve is fitted to the intake line, it must be fully open. If the pump has an inlet strainer or filter, it is important for it not to become clogged. A clogged inlet strainer or restricted intake line will cause the fluid in the intake line to vaporize. While cavitation can occur just about anywhere within a hydraulic circuit, it commonly occurs at the pump. In extreme cases, cavitation can cause mechanical failure of system components. Cavitation causes metal erosion, which damages hydraulic components and contaminates the fluid. The consequences of cavitation in a hydraulic system can be serious. This results in the formation of vapor cavities within the fluid, which implode when compressed, causing a characteristic knocking noise. This causes the absolute pressure in that part of the circuit to fall below the vapor pressure of the hydraulic fluid. Check the condition of the pump shaft seal and if it is leaking, replace it.Ĭavitation occurs when the volume of fluid demanded by any part of a hydraulic circuit exceeds the volume of fluid being supplied. In some systems, air can enter the pump through its shaft seal. If the fluid level in the reservoir is low, a vortex can develop, allowing air to enter the pump intake.Ĭheck the fluid level in the reservoir, and if low, fill to the correct level. Flexible intake lines can become porous with age therefore, replace old or suspect intake lines. For this reason, it is important to make sure pump intake lines are in good condition and all clamps and fittings are tight. Aeration accelerates degradation of the fluid and causes damage to system components through loss of lubrication, overheating and burning of seals.Īir usually enters the hydraulic system through the pump’s inlet. Other symptoms include foaming of the fluid and erratic actuator movement. Air in the hydraulic fluid makes an alarming banging or knocking noise when it compresses and decompresses, as it circulates through the system. Aeration occurs when air contaminates the hydraulic fluid. These symptoms are abnormal noise, high fluid temperature and slow operation.Ībnormal noise in hydraulic systems is often caused by aeration or cavitation. In the case of hydraulic systems, there are three easily detectable symptoms that give early warning of root cause conditions. Kraken Automotive can help replace and recycle that old filter quick and easy, and you don’t even have to leave your house.Proactive maintenance emphasizes the routine detection and correction of root cause conditions that would otherwise lead to equipment failure. If you are between oil changes and notice it is loose, don’t fret. The best time of course to change one is at your routine oil change. It can be extremely frustrating, thankfully oil filters are pretty easy to replace on most makes and models. This is when the old gasket sticks to the mating surface of the engine during removal and a new gasket is installed on top of it. Double gasket (happens more often than you think).It is possible it was properly tightened the first time and came loose again, but why? Below are a few reasons how that can happen: If you are sure your filter is loose, and leaking oil. If the gasket gets pinched it can create a leak even if the filter is tight. How severe it is will depend on how loose the oil filter actually gets. Since your oil pump is constantly pushing oil through the engine and the filter, a decent amount could be lost through the broken seal or improperly secured filter. If it is loose, you can definately have a leak. If an oil filter becomes loose, it can end in serious engine problems. In addition it also helps regulate oil pressure to ensure they all stay properly lubricated. An engine oil filter helps keep debris from entering your engines vital parts. Clean engine oil is essential to keeping a vehicle running smoothly, but what helps clean the oil? An oil filter of course. ![]()
