Reasons for bearing wear
1. Decreased tensile strength of metal, jagged scratches
2. Improperly planted; bright (polished) stripes
3.Scratched by dirt; dirt has entered the surface of the bearing
4. Lack of oil; worn top layer
5. Excessive wear; the top layer is wiped off over the entire surface
6. The bearing is deformed; the top layer was wiped off in a circle
Examination
Although the old bearing shells are replaced with new ones when the engine is overhauled, the old bearing shells must be carefully inspected. Inspection of the liner can reveal the cause of its wear.
Bearing failure occurs due to lack of lubrication, the presence of dirt and other foreign particles, motor overload and corrosion.
Insert selection
For the correct selection of liners, be guided by the size of the lubrication gap, which can be measured using a plastic measuring tape. If you have any problems with the selection of liners, contact the specialists.
