How much do you know about the ten taboos in construction machinery maintenance? Today we will take a look at the third item.

New cylinder liners and pistons are installed without options

When replacing the cylinder liner and piston, it is considered that the new cylinder liner and piston are standard parts and are interchangeable, and they can be used as soon as they are installed. In fact, the dimensions of the cylinder liner and piston have a certain tolerance range. If the largest size cylinder liner is matched with the smallest size piston, the matching gap will be too large, resulting in weak compression and difficulty in starting. Therefore, when replacing, you must check the size grouping codes of the standard cylinder liner and piston. The cylinder liner and piston used must make the size grouping code of the standard piston and the standard cylinder liner the same. Only in this way can the difference between the two be guaranteed. Has standard fit clearance. In addition, when installing cylinder liners and pistons with the same group code in each cylinder, attention should also be paid to inspecting the cylinder plug clearance before installation. In order to ensure assembly standards, an inspection should be conducted before installation to prevent the installation of fake and inferior products.
