How to carry out the sliding bearing blow grind

Before scraping carefully review the journal is not smooth, there is not rust, bumps and other composite bearing defects, if any should first try to eliminate; then view the status of the journal and the shaft touch to view the way in shaft diameter Apply a thin layer of Reagent (such as red lead powder, red Qian oil), then packed in journal bearings, rolling hand turn to a couple of positive and negative direction, lift shafts, bearing color view point spread condition, if not normal color point spread or foundation not turn, begin scraping ability.

     When scraping, should be based on conditions, the adoption of the first re-light, left light heavy scraping, scraping large bearing stay small criteria. Beginning a few times, the hand can be heavier, more scrape some metal to quickly reach better {TodayHot} of contact. When the touch area reach 50%, it should scuffing. Every once scraped off, wipe the tile surface, and then appeared in the journal repellent checking view, and then based on touch status scraping, until fit skills needs to stop. View scraping agents can use to show, but in the end during the period of high demand for fine touch point bearing, scraping can not use Reagent. Because, after the coating agent appeared, bearing the color point is too large and difficult to distinguish the practice of touch situation. In this case, you can wipe the journal, bearing directly on the check, and then remove the shaft, bearings can be seen on the highlights, is the touch point. And then the highlights were scraping, until fit skills needs to stop.

When scraping, not as long as the touch point fit the skill requirements, and also to make the side gap and angle of arrival touch skills needs. Usually the first touch point research, but also take care of the touch angle, eventually Zaigua side gap. However, some touch and non-touch should not have some clear boundaries with your fingers to wipe the surface of the bearing, should imperceptible traces.
