Well as you know I am looking for the required spare parts for my Eaton M62 supercharger in order to do a precaution service. Well today I managed to find the first part. I bought the pulley bearing. The shop did not hadvethe Nachi bearing (was out of stock), but we found together with the seller the dimensions of the nachi bearing and I got a PFI bearing (made in USA), which has exactly the same dimensions. And the price? Only 10 euro! ;)
