    Noisey bearing on front wheel of 997 with just 202 hours.

    Bearing noise heard on left front wheel of 997 during 200 hour maintenance by spinning it by hand
    and comparing it to the right wheel.
    Spun as free as the right wheel, no hang ups, but was noisy.

    Pulled the castor down, (an el cheapo 12 ton press does a great job doing this).

    Found that one bearing was noisy and one was OK.

    The noisy one was curded up with dried grease, the good one still had good grease on it,
    but not very much.

    Cleaned both with kerosene and repacked with JD *blue* lithium base high moisture environment grease.

    Checked both bearings for any hang ups or glitches while rolling in my hands, seemed to be
    OK now.

    Coated all internal bushings, spacers and axle shaft with Anti-Seize, these parts really
    need the anti-seize because they can rust and lock up on the bolt axle.

    Reassembled and checked out, no bearing noise, feels good spinning.

    Suspect the bearings weren't properly packed with enough grease to start with from the looks of the better
    one.
    No way should this have happened with just 202 hours had the caster been properly assembled and greased
    from the get-go.

    Will pull down the right wheel to check, even though it sounds good spinning, suspect not enough grease
    on them either.

    Might be a good idea to jack up the front end and check the spinning and sound once or twice a year, imho.

    It looks like you avoided a future failure. It's surprising that there isn't a better hub setup on a top-of-the-line machine like yours. It's hard to tell from the photos, which are very nice, by the way: Are there rubber / composite seals protecting the bearings or just the metal end plates?

    Good thing you were spinning your wheels ...

    Just metal end caps with felt washers, sure ain't water/moisture proof.
    Not a good design all the way around, the hub thickness is really too thin to drill out and tap for a zerk.

    Found a bearing number on them and the specs (OD,ID and thickness) matched out the measurements I found with my
    caliper micrometer.
    No manufacturer name on them and judging by the minimal lubrication, pretty sure they are Chinese crap.

    I took a look at JDParts after asking about the seals earlier. I was underwhelmed. Granted, the caster wheels don't do much except carry the front end and swivel, but their design leaves a lot to be desired.

    Good thing you don't live near a big swamp where moisture might be a concern.

    Good on you for catching this! A little quiet time with your machine does wonders in a maintenance perspective.

    Yeah - I would do the other side now while you are at it.

    OC, Good post.
    The first time I went to grease our Z915B,,,,, what the hell, no fittings on the front casters.
    Our Toro Z-Master had them.

    It is a link to Granger for bearing number 6205-2RS1 which is the number listed on JD parts along with the JD number. If this is the right size, you should be able to use this number to search for a US made bearing, if the Dayton is not. I have never heard of Dayton bearings.

    It looks like the link won't work, but I found it by Googling the 6205-2RS1.

    Houma bearing service about 30 miles down the road handles Timken bearings, they have a very big stock of bearings.
    If I ever need a new bearing for anything, I go to them, they never had to order, always in stock.

    This is the third thing that bugs me about the 997.

    The deck lift bearings are just sleeve pillow block type bearings with no zerks on all four.
    The owners manual says to pump grease in them from the *Zerks* every grease job.
    The JD service manual says the same, even a picture of the pillow block with a zerk.

    I really hate when the bean counters decide to save a few bucks by doing crap like that.

    ...and I would be happy to have a u-joint on my 2320 that did not require greasing, because it's so damn hard to get to.

    Those castor forks don't resemble the ones on the other Ztraks. Wonder why they went to a thinner and added a metal piece between the spindle and the fork.
