I replace this needle bearings every 2 years or 50 000 km. After 25 000 km it will look like on your photos.
But they will be able to work even 1 year. If you use a water-repellent grease. The original bearing I could not find. I used bearings which are located in the clutch flywheel alfa 75. They are available for sale.
But.It outer diameter has more 1 mm. And the same inner diameter greater than the original.
I changed the outer diameter of the bracket. Then I made a new shaft, mine shaft was corrosion. The new shaft I made with a smaller diameter and produced a removable sleeve. Which are replaced with new bearings. Now the shaft is still not damaged by corrosion.
This procedure needs metalworking machines. For sleeve require heat treatment and grinding. If such a procedure is possible for you. I will try to make a detailed description with the size and pictures of this.
