Piston ring installation method
In the parts of the engine, the piston ring is very delicate, slightly bad will affect the performance of the engine, so the installation of piston ring to be extra carefully, if improper installation will cause engine failure, and thus can not give full play to the working performance of the piston ring. Here is the installation method of piston ring we must pay attention to the following.
Piston ring installation preparation
Before installation should thoroughly check the piston ring and the ring groove is clean, in the installation and assembly process should be completely clean.
The first measurement of cylinder bore of cylinder piston ring assembly, the adaptability is a certain limit, wear old cylinder and deformation degree, new cylinder processing precision, must check whether they comply with regulations.
The piston ring installation steps
A, YL, Y marking must face upward.
Two, installation of pingzheng.
The performance of piston ring with air tightness is most important. If by twisting, will produce permanent deformation (Figure), which can not be kept completely sealed in the ring groove. Hand piston ring upscaled to the ring groove to, it is easy to distort, due to extensional stress axial distortions in the ring in the direction of the force, sometimes the piston rings broken. Therefore, it is necessary to pay attention to environment protection piston to Pingzheng, and at the opening should be possible only with the right of the tangential force, so be sure to use disassembly tool to install.
