[QUOTE="Tazza, post: 3095, member: 82"] Can you try moving the motor to the other side? this way you know if its the motor or the pump. You will need to rotate your fittings to join back to the hoses. It will most probably leak a bit of oil, but for the time being let it leak a little untill you have it all sorted out and you can replace the O rings. I re-read your post and noticed you said the steering lever felt like it wasn't connected. My 731 when cold going down hills at high speed sometimes does this. Pushing the levers forward then going to stop by pulling the levers back the machine swings to the right and the left hand lever feels like nothing. I push it back forward then pull back and it works. This is ONLY when cold, it warms up and works 100%. It could be a problem with your rotating group in the pump if the motor swap doesn't work. Keep this to a last resort, do the easier things first, the inside of the pumps are quite simple, but the parts are very expensive. Have you tried pestering your local dealer? It may pay to get them to do a flow and pressure test on your hydrostats, then you will know what the state of your pump is. Just a thought, never hurts to get a price. *if* you have to remove the pump, i found the easiest way is to remove and plug the hoses to the motors at the motor end. Remove the hoses to the super charge port on the pump and any others that need to go. Remove the pump with the 4 hydro motor hoses still attached. They are a swine to un-do at the pump end. Let me know how it all goes! [/QUOTE]
