    Water in bearings?

    Is there any easy way to tell if I've got a problem with water in my pump bearing (Aside from removing the pump cone and visually seeing it)?

    Would a barely audible, high-pitched, whistle sound be in any way indicative of a bearing problem?

    When flipping my wear ring a couple months ago, I did find a small amount of water inside my pump cone. I replaced all of the bearing grease in the pump cone with fresh OEM bearing grease. My RXT seems to be riding perfectly, but I can hear a very faint whistle sound...Not sure if it was always there or it's just the wind, I might just be paranoid. I seem to only be able to hear it when giving a little gas, and not during idling. Can't really tell at all where it's coming from.

    Thanks for any help,

    TheEngineer

    sounds like it might be your supercharger that you're hearing

    Hmm, it could be...I just don't remember hearing it before, and I've got 80 hours on the ski. It sounds different than the regular super charger reving sound. Very faint, and very high-pitched whistling. It's so faint though, that I guess it's possible I just never noticed it before.

    Usually the ability to notice something different and then go after it, will keep you running without a surprise. Have you changed anything else? Doesn't seem likely you would hear pump bearing under water?

    Another thought, pull seat off temporarily and listen for source?

    If you have already found water inside your pump... putting new grease in it will not solve that problem! More than likely... your front pump shaft seals are leaking. None the less... you have an issue that needs to be addressed.

    Just pull your cone and check the grease... you will see if you have any water in there as the grease will turn black. Although... 150 hrs. is a lot on the bearing, I did a complete rebuild on my pump at 150 hrs as well.

    Aha! Gotcha! I'll be sending you my pump shortly.

    Seriously..When I pull the pump cone off, there is yellow grease in the cone and yellow with a little brown grease on the bearings.

    Dang! Whats a pump rebuild going to cost me?

    Send it on homie (UPS PLEASE)... As I haven't seen my UPS chick in a while ...

    If your grease looks good, and your not trashing wear rings from excessive bearing play... let it ride as long as you can!!!
