56picup,

I copied and pasted the MBS number in the google search bar. It brings up a link to their site where they show that number as being a tapered roller bearing. Their site shows no ball bearings. You might want to check the online site for MBS. Good luck.

Stuart.

Arch - 909052R should be a roller, and there was a thread quite some time back about them, but I didn't find any suggestions panned out

of course, none of the repro places will tell you what the numbers are on the bearings they sell, and I've never been able to find rollers the right size to fit correctly, tho I've mic-ed new ball bearings and had 2 major bearing places try to match the specs in a roller

considering that the trucks work fine w/ ball bearings and that there are some quality newer vehicles that use'em, rollers aren't an "upgrade" but a modification - no reason to prefer'em - let us know if you find some that work! grin

I'm still running ball bearings in all of my trucks, even the one that had an 8' plow on it with no problems. I agree with Bill, not really an upgrade in my opinion. Besides, you can buy a lot of ball bearings for the price of one of those special made tapers,

Stuart, I'm wanting to switch over to roller bearings but need numbers to order them from my local parts supply (figure they'll be lots cheaper then thru one of the catalogs)..are the the numbers you gave good for over-the-counter ordering?? Are those front or rear??

Inner seal: National #6064
Inner bearing and race: MBS #909052R
Outer race: Timken #LM11919
Outer bearing: Timken #LM11949

Larry - re-read Stuarts post - not his information, but from here - also see this thread

been cussed and discussed here a number of times over the years, and as I said above, after much research I was unable to find any bearings that were the exact correct size for the TF spindle and drum - GM engineers chose ball bearings over rollers for a reason [rollers are not "modern" and are used on some 50's models], and if everything is correct, they are fine and last a loooong time w/ no trouble - overtightening is a major cause of problems

discussion not applicable to the rear axle

I tend to agree that there is nothing wrong with ball bearings, but am a little concerned about 70-75 mph interstate driving--very common when we drive to car and truck events some distance from home. If this whole thing doesn't pan out, I'll just go back to ball bearings.

However, this is what I've found out so far. Both are roller bearing and race part numbers.

Classic Performance Products kit at $119:

Seal: National 6064
Inner: MBS 909052R
Outer: MBS 909067R

Chevies of the '40s at $235:

(Why so much, I don't know.)

Seal: 3656536
Inner: 909052R
Outer: 909001R

Tech at CPP did say they have experienced some problems with the seal seating and had to use a hammer and punch at 12-3-6-9 to get it to seat. Sounds kinda' hokey.

Well, off to check with local bearing supplier. I'll report back.

I am with red58 on this subject. I just found the numbers in a previous thread, as noted, and thought I would pass the information on to Arch for his further research. There are many tapered roller bearing and race combinations available, called out, not by application, but by ID, OD, stack height etc. If a person wanted to, you could probably adapt anything to these newer style bearing...are they better, who knows!

There are even more seals available, in a million different configurations and compounds. The trouble with all of this is finding the right person at the counter who has the time and inclination to help you. Sometimes it's tough for the owner of the local parts store to spend an hour with Sammy Stovebolt in his search for a 35 cent part. He has bread to put on his table too.

Stuart.

Just got back from Precision Bearing here in Omaha. Their books do show that the numbers in my previous post are ball bearings, however, the pics on Chevies of the '40's are rollers. Am taking another roll of the dice and placing an order with CPP as their cost is approx. 1/2 of anything else I've been able to come up with and they are great about returns.

56picup,

I hope we will learn from your determination and research. In regards to the fellows comments about how to drive a seal in..I'm with you on that. Sounds like he has access to lots of free seals. Maybe he was referring to driving in the bearing race.

Stuart.
