Bearing buddies wear out?

6 posts in this topic

I am going to replace the bearings and grease seals on my boat trailer. My question is should I replace my bearing buddies also? does anything wear out on them? They are probably 15 years old, seem to work fine. Thanks for any thoughts

Shouldn't have to, CH. Basically they are a spring loaded device that pushes the grease at about 3-4 psi or so against bearings to keep water out when launching into and retrieving from water. The warm hubs suddenly contract when they hit the cool water, creating a vacuum, sucking water in. The bearing buddy helps prevent this. I occasionally took mine apart, checked the backing plates, and gave the springs a bit of a "stretch".

I agree with Reb. The only thing I like to do is use the bra that you can get. Smear a little grease around the outside were it slips on. This way it make a waterproof seal and keeps the dirt out of the bearing buddy. I like to smear grease around the zirt as well to protect against rust.

It never occurred to me that something like bearing buddies with not much in the way of moving parts could wear out.

  If they haven't had the bra on them, take them apart and clean them. Otherwise they should last forever.

    • Haula is probably going to see a lot of playing time so I don't doubt he will have some nice years, kind of like how Brodziak scored 20 playing as our first line center. I like Schroeder as first call up or emergency player but he just can't consistently bring it in the NHL, that is no crime because when he gets hot he is fun to watch but he just can't stay there. 
    • That's some good info, Thanks.
    •   I think they're shut down, too.  Smells like no money and more welfare...    
    •   Not sure if their still producing cardboard up at that plant anymore?
    • Now Haula and Tuch will have career seasons next year.  Haula is the odds on favorite to win the Ross trophy and Tuch should have a couple Norris' in the next 5 years.     Sounds like Wild might not bring Schroeder back either.  I really hope they are contenders for a strong center or a really nice goal scorer.  
    • Good point about the center support.  I wandered out to my ground blind on one of the last days of archery season to find the roof caved in and two poles busted. 
    • MMmmm Cloquet....   Smells like money.
    • I am a little concerned with it fading but it needs to be left up for the deer to get accustomed to it so no way around that.   I assume the sun is the main culprit in fading so I'll do my best to protect against that.  One spot I'm considering is tucked into some pines which create a lot of shade, brushing it in heavily should also help keep it out of direct sun as well.   Good point about a center support to help with the snow.  I'll make sure to add something.
    • interesting? oh its raining here too!!!!!!!!!!!
    • That's what this Cooper's Hawk was doing, right in the middle of the street. Has a nest in the top of the neighbors birch tree. Watched them all Spring with their young. Was pouring buckets here and this guy sat in the middle of the street for ten minutes flapping and spinning around. Think he was having a good time! First and third shots are while he was fanning wings. Camera didn't want to subject auto-focus  on full zoom with the amount of rain coming down, but figgered I wanted to get the pics. Hawk was half a block away
