A few months ago, when Maragon Hydraulics’ quality control department checked the quality of hundreds of A2FM45 cylinder blocks delivered by one of our hydraulic parts suppliers, they found that some of the cylinder block piston holes were 2/3 of the way from the orifice (there were steps in the piston holes), for details, pls refer to the picture as shown hereby.

Anyone who is engaged in hydraulic repair or an experienced hydraulic expert knows that the steps inside the piston hole should never be found, which can instantly destroy the piston and piston rings or shorten the service life of the remanufactured pump or motor. The steps inside the piston hole are like a sharp knife or a steel file which keeps scraping the piston and rings back and forth, causing them to be damaged abnormally.

The improper manufacturing of the production line workers is the root cause of this quality problem, but the manufacturer's production line quality inspectors and the final product warehousing quality inspectors are also negligent, allowing the improper operation of the workers, failing to find this quality defect in time and finally letting these inferior A2FM45 cylinder blocks with step holes be sent to customers and sold to the market is the most unacceptable.

If the quality control personnel from Maragon Hydraulics are also irresponsible or have no experience in how to check and control the quality, these poor quality cylinder blocks with step holes may be sold to the end customers all over the world.
