In the construction and repair process, Used digging machines offer, at a construction machinery facelift cylinder liners and piston, that the new cylinder liners and pistons are standard parts are interchangeable, put something you can use. In fact, the size of the piston and cylinder liner has a certain tolerance range. As the maximum size of the cylinder liner coupled with a minimum size of the piston causes the gap is too large, hand digging machines offer the market, resulting in compression weakness, difficulty in starting. Therefore, we must check the cylinder liner and piston Dress standard size grouping code, liner fitted with a standard piston and piston must be the size of a packet the size of the code and standard Cylinder same grouping code, the only way to guarantee between a standard with the gap. Excavators regular maintenance is to restore the performance and extend the life of its effective way, used digging machine price quotes, but in actual operation and maintenance process, because some of the use and maintenance personnel, but there are many wrong practices, will also affect the Construction Machinery normal use. Today Dulwich used excavator sales company small series and our friends talk about oil drilling machine bogey on maintenance Note the only plus not change.
