Hey, i also have a white 6105 fwa. I recently did a seal kit on the power steering pump (danfoss), the filters were changed last fall, and only have a couple hundred hours on them. After taking the power steering pump out (the pump was in really good shape) and installing all the new seals after it was leaking really bad, we have lost all power steering. Even when it was leaking we still had steering. I tried to work the air out out of the system and by lifting the front end with the loader and turning it to lock both way, and cracking the hydraulic lines at the steering rams, but nothing. Any other suggestions?
