Anyone have the Brearing #'s handy

Just a sec......... <digging thru notebook>

 

Drum brake or Closed knuckle inner wheel bearing seal is National # 8430s. Hopefully William_CJ3b can help with the bearing #'s as I don't have them here. Nickmil.

 

OK, ready???

For '55-64 CJ's

Seal - BCA Bearings - 6626S and Timken - 6626S

Bearing - BCA & Timken - 18590

Race - BCA & Timken - 18520

BCA = Advance
Timken = Autozone

 

.......above PN's are correct if your inner seal diameter is 2 7/8". If its 3" you have '65 or later spindles/hubs and/or later axle. nickmil mentions the seal PN for the '65-'76? CJ's.

 

Interesting. Didn't realize there were different seals for the drum brake applications. I know When Jeep went to disc brakes on the CJ's in '77 they changed the ID of the seal because of the larger inner bearing and what not. I'll have to investigate further.....

There is a difference...ruined a hub and the replacement has a 2 7/8 " opening..my original one has a 3" opening...race and seal won't fit

 

Yep, I think the change fell in line with the switch to 10" drums. Took me a while to figure out when I first got the 3B. Then took even longer to convince the parts stores

'41-64 M, CJ, Wagon, Truck w/dana 25 - all use same seals and bearings, inner and outer bearings are identical.

'65-'71 CJ - all use same seals and bearings, inner and outer bearings are identical (72-76 seal is the same as 65-71, bearings I'm not sure except that the inner/outer are the same)

'77-86 CJ - larger seal, new spindles, inner wheel bearing and outer are NOT the same PN.

 

New replacements for both the early (41-64) and late (65-80) hubs are available.

 

William 3b is absolutely right, I stand corrected. It can't be a 10" brake thing though because my '59 had the factory swedged-stud 9" brake drums and used the 8430s seal. Someone could have changed the front end but the hub and drum were definitely factory swedged together. That's why I was curious about the other seal. Already knew about the other bearings. The earlier bearings and races are thinner and the hub is different because of it. I dug around in my BCA bearing book that goes from '46-'79 and according to the book the breakdown is as follows:

1946 to 12/31/61 uses National seal # 40566s I'm sure these are the same seals for '45 and older but could be wrong

1962 up to 1976 all drum brake uses the 8430s seal

1977 up uses #4131 seal due to the disc brake spindle being different.

Interesting that your info and my info are different by the year they went to the 8430s seal. Probably a glitch in the books somewhere.
