Where the metric ball joint rod end is missing or unable to use the press, the end rod joint bearing can be mounted with the assembly sleeve and the small hammer. The hammering force should be transmitted evenly to the entire circumference of the end face of the end rod joint bearing ring, so the hammered end face of the assembly casing should be made spherical.
During the installation of the metric ball joint rod end, the required force is related to the size of the joint bearing and the amount of interference. For medium or large joint bearings with large interference, the hot charging method is commonly used. Before hot loading, put the end rod joint bearing or the separable joint bearing ring into the fuel tank or special heater and heat evenly to 80-100 °C, not more than 100 °C.
The metric ball joint rod end needs skillful operation skills to a certain extent. When the joint bearing is taken out from the heating oil tank or the heat device, the oil track and the attached material on the surface of the joint bearing should be wiped off immediately with a clean cloth. (Be careful not to use cotton yarn), then place it in front of the mating surface and push the joint bearing to the shoulder against it in one operation. Always tighten during the cooling process or tap the joint bearing with a small hammer through the fitting sleeve to make it tight. When installing the end rod joint bearing, the joint bearing should be slightly rotated to avoid the installation from tipping or jamming.
