Sep 12, 2013 · Air leaking into the hydraulics will cause the pump to cavitate and make noise. Also, keep an eye on your engine oil level. If the hydraulic pump bearing and seal go out, it could dump hydraulic fluid into the engine crankcase. So if the engine level goes above full, it's probably from the hydraulic pump. Just be sure it's your hydraulic pump
Learn MoreOct 08, 2010 · 1) The hydraulic pump has a busted seal and the hydraulic pressure pushes oil through the pump shaft into the engine. 2) The transmission fluid leaks to the engine through the clutch and then to the crankcase. I think number 2 is unlikely. Oil would probably leak down from the clutch housing.
Learn MoreAug 21, 2019 · Pumps and motors can be another major source of internal leakage problems and are usually the source of major leakage problems. The cause of internal leaks on pumps and motors is simple: excessive clearance between components that leads to a significant loss in volumetric efficiency (also known as slippage). Tracking Down the Source of Internal Leaks
Learn MoreJun 02, 2020 · The whining noise caused by air leaks is similar to cavitation, but is more erratic in nature due to the uneven distribution of the air in the hydraulic system. In addition to noise problems, aerated oil also leads to other issues such as sluggish performance, reduced lubrication and increased wear, damage to seals and increased contamination.

Learn MoreFinding the hydraulic leak can often be a much more challenging task. Luckily, tractors have relatively small hydraulic systems and few hydraulic components. So there are not many places for hydraulic fluid to leak from. Gravity, vibrating parts, dirt and debris all combine to mask the origin of hydraulic leaks.
Learn MoreCheck the fluid level in the reservoir, and if low, fill to the correct level. In some systems, air can enter the pump through its shaft seal. Check the condition of the pump shaft seal and if it is leaking, replace it. Cavitation occurs when the volume of fluid demanded by any part of a hydraulic circuit exceeds the volume of fluid being supplied.

If the shaft seal is leaking now would be a good time to change it, otherwise put it back in and "test don't guess". The front pump depends upon a supply of oil from the transmission pump and if the transmission pump is not doing its job the front pump cannot do anything.
