    Well we have been doing it and have not had bearing going out on top. #1 the bearing will not have alot of grease in them when you buy them.. Check them and see about the grease. If you have no grease how long will it run?

    if it has two seals, it is probably a sealed cassette bearing and therefore would require no grease. they may not come with what seems like much in them, but it has to have room to expand and be able not to push it past the seal.

    Are the bearings pressed onto the spindle or just interference fit? Also, how much slop is too much slop? I currently have about 2mm of up and down movement in the spindle. Before that I had absolutely zero up/down movement. I assume 2mm isn't too bad yet I don't want it to get out of hand and wipe out other parts as well.

    Thanks for your replies.

    The bearings just slide onto the shaft. It is easier to slide them on with a little grease or a film of oil on the shaft. The up and down is not much of a problem. It is the side to side movement of the bearing, in each bearing location that is the problem. When the bearing is installed in it's location, you should have to press, or drive it firmly into place. I use a wood block about 1 1/2" square and a hammer to TAP the bearings into their locations. If the bearing fall into, falls out off, or spins in the bearing location, then, the spindle housing is too worn and needs replaced.
    Do not remove any seals from the double-sealed bearing. As a Grasshopper dealer, I can tell you that those bearings can last hundreds and hundreds of hours just like they come with the seals. They are pre-lubed at the bearing factory. As the seal finally wears, you will actually be forcing new grease into that bearing every time you grease. So, the bearing is not going to run dry, even when it has lots of hours on it.
    hope this helps.

    Extremely helpful Mowingman, fastcutter, joshco84, and the rest of you. My deck is a 9861 does anybody know what the right part# bearings I need? I googled grasshopper parts and got a parts supplier website but it was unclear what the part# was for the far right spindle (when sitting in the seat).

    Thanks,
    Red

    if your spindle is loose then you probably DON'T want to rebuild it. just replace it. it sounds about like the hub removal/replacement on the hustler z i just did. quite simple, actually.

    I install the the jugs from a 72 in the 61 deck.. They work alot better. I don't like the Alum. ones...

    Just my 2 cents worth..

    probably better off with the cast iron hub. that's what the hustler uses in the 60". might even be the same part # from oregon. got one for sale!
