    Yacht Club Trailer - Bearing Grease

    Hi All,

    I have a relatively new trailer, 2018 Yacht Club (I think its the WC112). Just got our '18 Waverunner last July. I want to make sure I'm doing the preventative maintenance for the bearings, so I decided to grease the hubs.

    It just has the standard caps, no bearing buddies. Grease looks good inside. The back of the hub has a Zerc fitting, so I put about 5 pumps in there. I've heard you don't want to blow the seals out so I made sure to only give that amount.

    Is there something I'm missing here? Not sure how you would purge out the old grease from either the back or the front if it has no bearing buddies? Maybe I'm wrong and you just want to make sure you are putting fresh grease in every so often to prevent moisture from getting in.........

    Did you have the dust cap removed when you pumped grease into the Zerk on the back side of the hub?

    I think that hub-with-Zerk-on-the-back-side is intended to allow fresh grease to be pushed into the back of the hub, and the old grease will travel towards the outside bearing and then exit through the dust cap opening.

    Pumping grease into the Zerk fitting while the dust cap is still installed might force excess grease out past the inner hub seal, which you donít want.

    Thanks K447! Perfect! Hadn't seen that before. I'll make sure the dust cap is off, then keep pumping grease until I start to see the old come out. Didn't think the old stuff looked bad really. Still looks brand new.

    I didn't see that "Rubber Plug" behind the dust cap in the diagram. Maybe its covered in grease? Not sure if that's referring to the style I don't have? My dust cap is solid.
