Plastic oil bath hub

[joeu235]

I've got a trailer built in 1994 that has a broken plastic cover for the oil bath hub. How do these come off and any idea how to get a replacement?

I believe they screw in.

Use a big pair of channellocks to take it out. Most trailer repair shops have them or can get them. Probably would be good idea to replace all of them, keep an old one for a spare.

It is a screw in cap, not sure of the size but it looks like a Fruehauf/Propar cap.
The cap had a large nut cast into it.
It is probably polycarbonate, I would try to just break it out or hit with a chisel and unscrew it.

Here is what the other 3 hubs look like. They are rough looking but the trailer is used to haul square bales and hasn't been over 5 miles an hour in the last 15 years.

I spent like 20 bucks to replace all of them on my trailers and To have spares. Cheap insurance. You need to do something and make sure there’s oil in there

Just googled H-A Hub Cap and found it looks like it is made by Dexter 2 7/8" hub cap.
You might even be able to get it at your local NAPA. ??

I thought they were typically clear so you could monitor oil level

They're clear when new.
They get dark with age and being stained by the gear oil.

I have an older 10t trailer and the caps are black, not stained but actually black plastic.
