The causes of hydraulic cylinder drift

 · The cylinder becomes hydraulically locked when the rod seal leaks due to pressure around the piston equalizing.It's this imbalance that causes the cylinder to drift towards either the extend or retract position, unable to hold a load at mid-stroke position.Occasionally, hydraulic fluid contaminated with dirt, grit, water or air is behind.

Loader leaking down : Normal or Abnormal

 · When I park the tractor with the loader off the ground, I have noticed that when I return to the tractor the next day, the loader has leaked down and is resting on the ground. I have also noticed that when loading dirt, the bucket will not always lift if i have a lot of forward pressure on the bucket while trying to lift the bucket.

70a loader cylinder size issue

 · My tractor was available with a 420 or 430 loader. The 430 loader CAME with 2" bore cylinders so the changes I made was within specs other than the increase in lift height. I checked my pressure and it was dead on the PSI factory specs so I left it where it was. Make sure the diameter of the cylinder will pass the mount bracket.

Adding down pressure to loader

 · Tractor: Massey 65 Diesel Loader: Freeman (seperate pump driven off the pto on the front) I'm in the process of adding down pressure to my loader. I've installed the new cylinders (old SA ones were leaking anyway). I took the plug out of the other side of the lift spool valve and hooked up the line thinking that would give me the down pressure with no success.

Loader doesn't hold hydraulic pressure

 · Let the loader sit for a period of time to see if it drifts down. If yes this would indicate the directional valve is leaking. If no this would indicate the seals on the cylinder piston seals are worn and the cylinders require rebuilding. Use the jack to raise the loader enough to reconnect the quick disconnect so that you can lower the loader.

Hydraulics for Loader

 · I plan on building a loader for my compact tractor (Ford ). I am wondering if I am missing something. If I want to use the internal hydraulic pump I believe all I need the tractor to supply is hydraulic pressue and I have to provide a return. Everything else is a function of the loader.

Hydraulic cylinder rod travel is slower than normal

 · That means that the pump flow has decreased from 5 GPM (18.75 Lpm) down to 2.5 GPM (8.45 Lpm), or 50%. Clearly, the only reason why the cylinder rod speed decreased is because the pump flow decreased, which simply means that any time the speed of a cylinder decreases, the problem MUST be a decrease in flow, and NOT a decrease in pressure.

Troubleshooting hydraulic cylinder drift

But because of the loss in effective area

Because of the loss in effective area due to pressure now acting on the rod-side annulus area, the static pressure in the cylinder must increase to support the same load. Remember, force developed by a cylinder is a product of pressure and area. For example, if the load-induced pressure on the piston side of the cylinder was 2,000 PSI and zero.
