480D CK Loader wont fully raise

Chad I have been using my FIL's 480 D CK to move some heavy objects on our land. Recently I noticed that the loader will not fully raise up when lifting an object. It will raise the bucket say 8' in the air, lifting the object, but then starts to bypass. However I can curl the bucket up no problem. It seemed all this started after blowing a hyd line to the RF lift cylinder. Are there any filters that need cleaned(other than the screw on), etc?? I see no signs of air in the hyd oil, and it wont start bypassing fluid immediatly, but wont fully extend either.

-loader will however raise fully with no weight.

AJ Plenty oil in the tank?.It sound as if there is a problem with the port valve for that function,when you curl the bucket fully notice the engine tone and check to see if the tone is the same when the bucket is fully raised,if not try adjusting the port valve for the lift.
