72 gear box main bearing.

Anyone see a problem using a main gear box bearing that is open on both sides. The original bearing has a dust shield on the drive side. I know there is a seal but with the sprocket slinging dirt and water i guess the shield was extra protection from debris.

I think the OEM bearing is just a normal, unsealed bearing..?

I bought a single-side sealed bearing from OldBritts for $25 or so and I think it worked out great. IMO, that extra sealed side can do nothing but good!

Thanks Jordon Thats what i was thinking too, but i have a new open bearing, so there goes another three days for parts.

I don't see why it wouldn't work just fine, I'm just saying I'll continue buying the single-side sealed ones (they're cheaper anyway)!

If you already have one that's the right size--sealed or not--I say use it. No sense wasting money on new parts when you have something that's perfectly good already! Save your money for things that (will) break.

The open bearing is fine, you don't really need the shielded bearing.

What he said. I needed a replacement and nearly died when I saw the non-sealed bearing was $110.. I found the shielded one for $22.50 and I like it. That said, you should use what you have, IMO!

I have a '74, went to CNW for a ND sleeve bearing, they sent a
off shore brand rubber sealed both sides one. I complained and
they said that they had been using them for at least a year with
no problems. OK to use it sealed or unsealed.
Havent yet implanted it and I do have a double shielded on from
RGM in stock. Matt is unlikely to steer anybody wrong and the
idea of a fully sealed bearing does have its pluses.
...and its minuses.
I dont think the big ball gives any trouble anyway.
Any comments?

Installed the unshield bearing today i guess it be ok. The housing seal i installed doesn't seem to be the best quality not like the original. I could just about install with finger pressure. So i put blue locktight and installed i guess if it doesn't leak it will be ok. The bearing p/n i installed is 1654 zzc3 KYK made in Japan. Motion Industries the former berry bearing said this bearing is a sealed bearing someone removed the dust shields. Bought bearings from rabers they said this is the bearing they use. Didn't ask if they removed the shields. Steve
