Maintenance of granny's bike (24 inches)

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.
At the time of replacing the grease, the screw thread of the mandrel after use was incorrect. The ball nut was difficult to disengage and the contact surface with the ball was rough and it was exchanged.

I doubt that the ball nut was a plated product (galvanized?). Since this nut comes into contact with the ball and it is a functional part rolling the ball, it does not plating and it is hard as it is quenched skin. Particularly in zinc plating, since hydrogen brittleness occurs on the surface, post-treatment is necessary for the portion to which force is applied. ... Looking at the photos, it's black, so it looks like quenched skin ... I'm sorry if it's my mistake.

I broke the axle and brought it to a bicycle store It was said that it was cheaper to buy a new one, since I consulted, I used this to exchange and repair it. Another prepared was bearings and grease on one side that fell out. You need tools without monkey wrench, hub spana, and boss free.

There was a description of "Silver" as a picture, and wording, but the product that arrived was gray, not silver ball. The same product of gray is sold as a set of rear axle for transmission by the same manufacturer, already purchased with Monotalau, the surface of the ball press was broken by using 4000 kilograms and it was torn. This is premature corruption. This time, arrival was gray despite ordering thought that Silver's ball push was wanted, not gray. The item of gray is rough, the surface of the ball push is rough, imagine that the friction is very large, I can not use it.
