    I have a sixty inch super z and just replaced the wheel motor. Now I can not get it to move. I changed the hydro fluid and lifted the drive wheels off the ground and let it run to get the air out of the system but the side I replaced is not spining and the other side is but it is real jerky. I did this for about 15 minutes and still no movement out of the side with the new motor. Any sugestions? Also both release nuts are tight. Thanks

    When you replaced the wheel motor did you replace the hydro filter? if so did you pre fill it?
    Did you also make sure the pump wasn't contaminated from the wheel motor failure? if there is still metal in the reservoir and you didn't completely flush every bit of the system you could of damaged the new wheel motor and the pump may be also.
    Regardless you need to get the unit up on jack stands and run it until all the air is out of the system, sometimes its 15 minutes, sometimes its a hour or more, depending on how much air is in the system and where it is trapped in the system.

    That is likely why it is going to take longer.
    Another thing to make sure of, make sure you dont have 2 rubber gaskets on the filter to mount connection, as in the old one may have not come off with the old filter.
    That will cause air to get into the system.

    Still have no power going to the wheel motor we replaced. Could air be getting in the system from somewhere else? I check all the lines and they are tight. I know air is in the system because the fluid is foaming and has bubbles in it.

    I would suggest you follow PJ's suggestion and then you need to have a lot of patience to get the air out.
    Once it is in the system it takes a lot of perseverance to get it out.
    Also the manual has some reference to bleed out air.
    I usually don't pre fill the filter because it is hard to do one person.
    But I let it run for a while before I touch the handles.

    Check the filter like PJ said for 2 gaskets and make sure it is tight.

    Either air is still getting into the system or the pump is shot.
    Did you have a dealer pressure test the pump before replacing the wheel motor?
