When replacing the cylinder liner and piston, it is considered that the new cylinder liner and piston are both standard parts, interchangeable and ready for use.
In fact, the cylinder sleeve and piston sizes have a certain tolerance range.
If the large size of the cylinder sleeve with a small size of the piston, will make fit clearance is too large, resulting in weak compression, start difficult.
Therefore, SINOTENG cautions that standard liner and piston size grouping codes should be checked when reloading. The liner and piston should be installed so that the standard piston size grouping codes are the same as the standard liner size grouping codes so that there is a standard fit gap between the two.
In addition, the cylinder installation with the same group of code cylinder liner and piston at the same time, but also pay attention to the inspection of cylinder plug clearance before installation, in order to ensure the assembly standard, before the installation should also be a test, to prevent the installation of fake inferior products.
