Re: Rear axle housing repair sleeves not hardened
Hello,
the circulating lubricating grooves are not good!
At that time in the past designers thought these grooves were necessary for the constant fat distribution.
Today it is known that these grooves interfere with the hydrodynamic pressure resistance of the lubricating film.
Therefore, all bearings have a smooth surface with a little rough-depth. (Never polished!)
