[QUOTE="Tazza, post: 14918, member: 82"] [FONT=Arial][SIZE=2] The brake discs are meant to flop around. They are held on a hexagonal shaft with a large sir clip. This is so they can essentially float to get in the correct position. They have NOTHING to do with steering, only for the park brake. All your drive is controlled with the big blue pump your steering levers attach to. This is a variable displacement piston pump that is fully reversible. Essentially your motors are attached to the pumps output so when you vary the amount of fluid the pump generates this in turn spins the motors at that speed. If you move the stick the other way the oil flow actually changes direction which makes the motor spin that way too. Seeing a diagram for this sure helps explain things. The chaincase only transfers power from the drive motor through a reduction box to the wheels, it also has the park brake. All the drive power generated between the pump and hydraulic motor. If it was my machine, as you said the oil was white and water came out. I would pull the pump and clean the insides out and make sure the rotating groups are still ok. If the pistons are stuck or the swash plates are worn this will cause a lack of drive. Really the motors should be pulled and cleaned as well. This is all up to you though. You may get away with dropping the oil several times to clean the system but as you said your drive on one side is not working I believe you have a pump issue. You can swap motors from side to side to confirm this, if the problem moves its the motor, if not its the pump. Hopefully you can get out of it cheaply.[/SIZE][/FONT] [/QUOTE]
