I have never had to use one of the speedi sleeves before but I'm thinking about getting one for the fan pulley, and rear pinion. From information gathered from another post the sleeve is not as wide as the surface on the pulley, or the pinion. The sleeves measure around 1/2". Do you only push them on until they are at the contact area of the seal? It's hard to tell the exact area were the seal contacts the shaft. I was thinking they would be as wide as the surface of the pulley.
The sleeves look to much cheaper at Rockauto than NAPA.
