View Full Version : Oil Bath Bearings question
05-18-2013, 09:05 PM
My trailer has the oil bath bearings system, I have nerver had this system. One of them is low on the visual indicator. It looks like you take the tire off pull out the plug and drain the system and re-fill with 50W oil. put plug back in.
If I am missing something please reply, I am thinking about doing this tomororw as we have storms coming our way.
thanks for any input.

What brand do you have???
I have Reliable and they recommend 50 wt half to three quarters up. I believe UFP says to fill them almost full

I have the Reliable brand on a 2004 model trailer. Owner's manual says 80-90st gear oil.
To answer the original question. Yes, you will have to pull the wheel to get the oil in. If you have the aluminum caps then there are definately seperate set screw plugs on the hub and the cap. reremoving just one of them allows you to put oil into the hub.

I finished the project today, one tip I found was use a oil can to fill then instead of funnel. That made it much easier. Next time I am taking trailer off boat and rent a slip for the day and do work on trailer and return for boat.

I found a ketchup/mustard dispenser bottle like at Walmart with the thin pointy cap works well also.
