Where to buy front oil bath seals...

I have some leaking front oil bath seals on my 97 international 3800. The seal I took out is a national b-370150-bg. A Google search does not reveal anything. I haven't tried the bus specialty places yet. Does anyone have an idea where to get these. The axle is a Spicer 8000lbs front axle.

Thanks

A google search revealed a whole bunch for me......

The first google hit says it's a discontinued seal from national/timken.

Crosses to SKF # 28758 for scotseal or 28759 for scotseal plus using the napa part number conversion.

Amazon shows both available.

Get the specs from skf for seal sizing and compare that to what you're working on to make sure it's an actual cross.

Thanks. I will look into the SKF ones. I was at the Napa srotr for 30 minutes on Saturday and the two seals he brought out were the correct diameter "at least by looks"
but there was an extra shoulder. It looks like there is on on finditparts.com. I will also try contacting national to see if there is a part that supersedes the old one. I will send an update when I get more info

supercedes to 370150a

All the above have the lip you're talking about.

I'd say it wouldn't be a problem unless you think it will interfere.

I have confirmed that booya is correctl. 370150A is the same seal. I just got of the phone with Timken. The tech on the phone said the letters were specific to the customer and specified ath coating on the seal. Good thing is there are three distributors about 2 miles from where I work. So I guess I will be buying some seals during lunch unless they are a lot cheaper online.

Thanks for the input all
