Oil Bath Hubs

[YellowMoomba0]

Hello everyone,

I got to thinking about the Oil Bath Hubs on my single axle trailer and wondered how often to change the oil. I suppose the manual is at home so I wrote an email to Boatmate. The reply was simple. Change the oil at least once a year, make sure it is always full, not milky etc. and to use SAE 50 weight Motor Oil. Never use Hypoid Gear Oil. UFP is the manf. of these hubs and more info is available at www.ufpnet.com

Id say my trailer has 1000 miles on it or so and I have never changed the Hub oil. Guess I will start tonight.

That makes two of us. I do change my beer more often though.

mine is 3 years old and I did it once. It wasn't hard except trying to get the oil into that little hole to fill the hub. I ended up having to use a syringe to get the oil in there without making a giant mess.

You have to jack up the wheel and remove it. Then there is a little screw in the hub that comes out and you drain it that way then refill through the same hole and put the screw back in with the allen wrench.

I've taken the trailer to a shop, i think they fill it with marine grease, when they call me to let me know that isaid NOOOOOOOOO!!!!!!, hope they where joking, if not what would happend?

I'd hate to know how long it took them to stuff all that grease in through the little holes in the hub. If they did it and it hasn't been towed around there shouldn't be any damage. They'll have to tear the hubs apart clean them out and fill them with oil. I find it hard to believe that a shop would do that though, since they obviously would have had to drain the oil first and there is not grease zert to use to fill them with grease.

Dumb question, but are you sure you have a trailer with oil bath hubs? I'm not sure when they switched over to these. Could also be that the person you talked to hadn't done the work on your boat and just gave you the standard answer for what they do to most trailers.

lowdrag, that is a good question in re: to what year they switched to the oil bath bearings.

my 02 boatmate trailer was grease and my 05 is oil bath.

i have probably put 6K miles on my trailer and the oil looks good.

Well, we may have an answer to that question. My '03 had oil bath. So I'm guessing that's the year they switched if your '02 didn't have them.
