The effect is similar to an air leak in the line. You can avoid this problem by moving the bucket slowly and/or simultaneously revving the engine to max.

The 7308 loader is spec'ed to lift about 900lbs on a TC33. So, place the 800lb object (axle) in your bucket along with another 100lbs of stuff. Make small adjustments to the pressure relief until the loader will just barely lift the load. Now, of course, we need someone to tell us where the adjustment point is.

Aug 21, 2020 · If the loader frame has no issue moving up and down that would say the pump and valve are good. I suspect one of the dump cylinders has had the piston come loose and partially seals to lift the load but does not seal in the opposite direction.
