Model T Ford Forum: Forum 2016: Rear bearing failed in my alternator

I have a 1924 Model T Coupe. Sometime in the 1990ís it was converted to a 12 V system with a distributor. It also had a Delco-Remy CS 121 alternator installed that is used on a lot of GM products. Three years ago, I had the alternator changed to self-activating and generally overhauled by a company that specializes in this type of work. Recently the rear bearing went out and I only have, perhaps 2,000 miles on it. Any ideas what could cause that bearing to fail in such a short time?

If it's removable you might be able to buy just the bearing. Take it to an auto parts shop to match it up. #'s and bearings are used for years & years so chances are it's available. Even foreign stuff uses bearings that are already being manufactured. Years back a $100 Nissan belt tensioner pulley used a $10 bearing that was the same as an older style Chrysler alternator. D something or other. I forget the #. Why did it fail? No tellin'.

The belt tensioner bearing on the Honda passport
(ISUZU RODEO) fails about once a year. The replacement bearing made in china costs about $7.00
The experience of changing it?... PRICELESS.
