WARNING. New DeDion bearings faulty

Post by MD » Wed Feb 26, 2020 2:15 am

Recently spent 2 days with the help of a friend trying to figure out the reason why the bearing seized up after the hub and the inner shaft connection was tightened up to spec. It turned out after testing outside of the DeDion mount that inner race clearances are wrong for the correct preload.
This is the FAG brand made in Slovakia number F-805791. DO NOT USE THEM.

If using the FAG brand, the correct part number is 545495 made in Germany.

These are no longer available in Oz hence the problem with the so called equivalent.

After some digging I found some substitutes that work well. See photos. I have never used this brand before. The fitment is great as for its durability, we shall see.
