1、Receive a fixed number of oil seal.

2、From oil seal to assembly, must be kept clean.

3、Before the assembly, good seal check, the size of each part was well consistent with the shaft seal and seal cavity size, before installation, the diameter size and seal diameter size should be consistent with the control clearly. The size of the cavity and the outer diameter of the oil seal should be suitable to check the framework oil seal lip is not damaged, deformed, spring has not fallen off, rust. To prevent the oil seal in the process of transport without flat, by external forces such as extrusion and impact, and undermine its true roundness.

4、The assembly before machining inspection procedures, a good amount of cavity axis and the size of each part is correct, especially in the chamfer, cannot have a slope, surface processing shaft and the cavity to be smooth, no burr and chamfer damage, clean assembly parts, loading at axis (chamfer) part no burr, sand and debris that will produce the seal lip irregular damage, suggest chamfer parts adopt R angle.

5、In the operating skills, you can feel it with your hands, whether smooth, true circle.

6、Before the installation of the oil seal not too early to tear the wrapping paper to prevent debris attached to the surface of the oil seal and into the work.

7、Before installing, should be on the lip seal between the amount of smear on the addition of lithium ester with MoS2, prevent the shaft in an instant startup, caused by dry grinding phenomenon of interference effects of lip, lip, and assembly as soon as possible. Installed oil seal oil seal seat, if not immediately installed, it is recommended to cover with a cloth to prevent foreign matter attached to the oil seal. Hand tools or coated grease must be clean.

8、The skeleton oil seal wants the paperback, cannot have the slanting phenomenon. Recommended use of hydraulic equipment or sleeve tool installation. Pressure should not be too large, the speed should be uniform, slow.

9、For the installation of the framework of the oil seal of the machine, do mark to facilitate tracking, careful attention to the whole process.
