    Pump bearings

    I pulled my pump out and found that it had water inside, the grease was white and u could see the water. still had standard cone fitted and the o rings looked ok. anyone had this before? So i removed the retaining clip and put a socket on the bearing and went to tap it out but its that tight i think it need to be pressed.? Can someone tell me if the bolt that holds the prop just slides out, seemed very firm

    You can tap it out it's tight but it can be done.,but then you will have to place a new bearing.
    I would recommend a rebuild,i did this myself without a press.
    For installing the new bearing place the pump in the oven for a bout 10 minutes,place the bearing in the freezer.
    The bearing will just slide in this way.
    Put the bolt also in the freezer,after installing the bearing wait a few minutes,this will allow the bearing to heat up a bit because the housing is still hot from the oven.
    Then gently tap the bolt in.
    And finish the rebuilt by installing the other parts.

    Thanks for the info Rich. So does the pump only have one bearing, it looks from the outside that it has 2.

    No only one bearing,but you can easily take it apart.
    I already did twice the way i described,and they perform fine,and no leaks.
