Main and connecting rod bearings — inspection (Opel Astra F)

It is necessary to check all bearings, including old ones, which will provide valuable information about the condition of the engine.

The main reason for bearing failure is lack of lubrication. To prevent this phenomenon in the future, it is necessary to find out the reasons for the disruption of normal lubrication.

Incorrect installation of the bearing can lead to its destruction. Strong tightening of bearings leaves insufficient clearance for lubrication and leads to oil starvation. Dirt and foreign particles cause the formation of bumps on the working surface, which leads to the destruction of the bearing.
