New cylinder liners and pistons are installed after selection

 

When replacing cylinder liners and pistons, it is considered that the new cylinder liners and pistons are standard parts and interchangeable, and can be used after installation. In fact, there is a certain tolerance range for the dimensions of cylinder liner and piston. If the cylinder sleeve with the largest size is matched with the piston with the smallest size, the clearance will be too large, resulting in weak compression and difficult starting. Therefore, the size grouping code of the standard cylinder liner and piston must be checked when replacing. The size grouping code of the standard piston and the size grouping code of the standard cylinder liner must be the same as the size grouping code of the standard cylinder liner. Only in this way the standard clearance between cylinder liners and pistons can be guaranteed. In addition, when installing cylinder liners and pistons with the same group code for each cylinder, should also be paid attention to the inspection of cylinder plug clearance before installation. In order to ensure the assembly standard, an inspection should also be carried out before installation.
