I had the same problem. If I tightened the nut, the mandrel would not turn. If I backed the nut off a little bit, the mandrel would turn. But that seemed unsafe. So I took it apart, and took it to a dealer. They told me that mine had been converted to a new style assembly. I also bought the two new Timken tapered roller bearings and two lip seals. The other parts appeared to be fine to both me and the dealer. I'm not sure it was assembled properly when I bought it. Can anyone provide advice on where to find a manual and an exploded parts drawing - particularly for the mandrel assembly. Thanks.
