The Ford Barn - View Single Post - throw-out bearing

I have seen 10 or 12 noisy Aetna bearings in different cars (ie not all in one car) in the last 15 years.

Every bad bearing was stamped "AETNA" just one word. so maybe these are the junk "INDIA" bearings.

Recently I found a used throw out bearing which looks very old and is greasy.

It was in an engine that had not been running in years.

It is stamped:

"Aetna Ball Bearing Manufacturing Co. A-7580-B 3"

NOT just "AETNA"

NOTE: Unlike the new T. O. Bearings, this bearing is open on the ID so grease can get inside bearing when the Zerk on the "bearing carrier" is used to apply grease.

Maybe this is a genuine Aetna bearing?
