Since the surface of the cone had been rough, but did not expect too much, as a result of the exchange is quite good. So also was replaced with the ball, I do not know the effect of the only core rod, if the ball press is worm-eaten state (is scratched), I think that is also good idea to exchange to this.
When the grease exchange, was exchanged for and the nut press threaded funny ball of the mandrel after was busy it was difficult out, it had been rough contact surface with the ball.

The question of ball press nut was plated product (zinc-plated?). This nut is in contact with the ball, because the functional portion of the ball is rolling, is as it is hardening the skin without the plating desirable. In particular, since zinc plating hydrogen embrittlement occurs on the surface, in part to take the force must have post-processing. If ... photos, so black, ... I'm sorry if I were you of misunderstanding seems to be hardening the skin.

Photos, and there was a description of the "Silver" as the wording, product arrived, rather than the sphere push of silver, was something of gray.
The product of gray, has been sold as a mandrel set later for the transmission of the same manufacturer, already purchased in Monotaro, the surface of the press sphere is damaged been harsh with the use of about 4000 kilometers. It's premature damage.
This time, instead of gray, despite the ordered thought that want sphere push of silver, arrival was gray.
Gray goods are rough the surface of the press sphere, to imagine that very friction is large, I do not feel like to use.
