    I am in the process of rebuilding a toploader to go into the mav. The instructions say to remove the output shaft bearing but doesn't say how to do it. So my question is how do I get the bearing off the output shaft?

    Thanks Stephen

    If you don't want to remove the shaft, you are going to have to work at it.
    remove the extension housing, the rubber seal behind the speedo gear, the speedo gear and drive ball. using a long puller and bearing splitter, pull the bearing off the rear of the output shaft.

    The other way is to remove the output shaft and then press the bearing off the shaft in a press. This requires removal of the gear train from the input shaft back and the above parts from behind the bearing.

    Thanks, I figured I would have to get a special puller to do it or remove all the gears and take the shaft to a press. I just wanted to make sure I didn't miss something since the instrutions simply said "remove bearing" I am going to go through the whole trans anyway so I will probalby just take to the press once I get all the gears out.

    What about when putting back together, does it have to be done the same way? Seems like it would be a lot easier to put the gears on the output shaft out side of the case. Can I just heat the bearing nad "slide" it on after the gears and output shaft is in the case?

    Yes, cool the shaft and heat the bearing to 300 F and slide it on.

    Last two Toploaders I rebuilt, the output bearing came off just using a hammer and punch. New bearings went on the same way. Just becareful you don't nick the shaft in doing so.

    Thanks for all the replies.

    Well I got it apart by taking all the gears off then pulling the output shaft out of the case. The output shaft is bad, about half of the splines at the front end, the ones that hold the snap ring on, of it are gone. The input shaft is twisted and I guess it took those splines with it. So since I need a new output shaft I am not too worried about getting the bearing off now.

    Is there anything else I should look at really good that could be damaged from the input shaft twisting?
