Schematic diagram of crankshaft installation

Where is the crankshaft installed? I believe that for some novice Xiaobai, this knowledge point is indeed a bit unpopular. But knowing more about cars will definitely help in the future. In order to answer this question, let's give a schematic diagram of crankshaft installation below.

The installation position of the crankshaft bush is actually on the fixed bracket of the crankshaft and the cylinder block, which not only supports and lubricates the crankshaft, but also has a positioning protrusion on each bush, which plays a role in the axial positioning of the crankshaft. effect. Then, its installation steps can be said to be relatively simple, as long as the positioning protrusion is clamped into the positioning groove inside the cylinder.

It is worth mentioning that after installing the new bearing into the seat hole, check the distance between each end of the upper and lower plates, which should be 0.03-0.05mm higher than the bearing seat plane. Because of this, it can ensure that the bearing shell and the seat hole are closely attached, thereby improving the heat dissipation effect. Secondly, the screw must reach the corresponding torque (10-20N·m). But don't overtighten it, otherwise it will cause the bolt to be overstressed, which will not only cause slippage of the internal thread, but also the bolt will have a certain chance of deformation.
