Since the tight rubber seal skeleton Installation Considerations

(1) Install oil seal, it shall be checked whether the journal surface is too rough, with or without injuries, especially without a long scar along the axial direction. If the journal surface is too rough, can easily damage the oil seal lip 1:3 or accelerated wear, damage its sealing performance. If the journal surface due to improper disassembly bludgeoning more serious injuries, oil seal lip will fit with the journal surface lax, resulting in oil leakage. In both cases, the Ministry of injuries can re-surfacing according to the provisions of the journal size lathe round, or replace the new axis. If the journal only metal burrs or burr shaft, etc., can be flat grinding rasp to prevent injuries when installing oil seal oil seal lip.
(2) Check the oil seal lip without breaking, cracking or oil corrosion damage, if any, of these negative phenomena, should be replaced with new oil seal.
(3) Install oil seal, to prevent oil security cable ties lip 121 is tensile deformation or scratch damage, to adopt special tools for installation. Without this tool can be installed dismount: first shaft portion even in the journal, the volume of the hard layer of transparent plastic film (commonly known as cellophane), cast on its surface a little oil, the oil into the wrapped plastic envelope film first axis, uniform force the seal slowly pushed to the journal, and then pull out the plastic film. Note: Do not put lip installed the wrong direction and should be made toward the inside of the oil being stored, a trademark, specifications side facing outward. Because only one-way sealing lip 1:3, if anti-oil package, will inevitably result in oil leakage, seal weakened or lapsed. To avoid the oil encapsulated crooked or stick with a hammer and other tools in the seal surface Luanqiao hard, or easy to make seals cause injury is.
(4) During the installation process, should maintain metal seal (especially the lip area) and the journal area clean, and pay attention not to spring out from the tight seal springs outside the tank. If the self-tightening spring relaxation, stretch weakened, depending on the circumstances of its period cut down securely connected to both ends of the head can continue to use.
