There are many threaded oil seals in automobiles. Although the price of threaded oil seals is not high according to the new market quotations of threaded oil seals, if the correct selection and installation of oil seals are ignored, oil leakage or liquid leakage failure will occur in the automobile, resulting in Problems such as pulling the cylinder, holding the shaft, and burning the gear. Therefore, every car maintenance personnel should pay attention to the selection and installation of threaded oil seals. Next, the editor will elaborate on the precautions for the installation of automotive thread oil seals?
1. Select the oil seal that meets the original design requirements
When car manufacturers design cars, they have made in-depth demonstrations and tests on the threaded oil seals used in various parts, and should not be arbitrarily replaced or substituted in the process of car maintenance. If you really can't find the original threaded oil seal and want to replace it with other oil seals, you need to check the data repeatedly, make a careful comparison and analysis, and treat the question of which product is the best threaded oil seal with a cautious attitude.
2. To disassemble and assemble the oil seal, the method should be gentle
When disassembling and assembling the threaded oil seal, the force should be uniform and the action should be gentle. Do not use hard, sharp edge and sharp tools to pry. For some threaded oil seals with tight fit, they can be assembled after slight heating if necessary, or a suitable copper milling machine can be selected for installation by light tapping. Because even a tiny scratch on the threaded oil seal will cause the oil seal to lose its proper sealing effect.
3. Wipe clean and install in the specified direction
Before installing the oil seal, the oil seal should be wiped clean. The parts in contact with the oil seal should also be cleaned together to prevent the dirt on the parts from deforming the oil seal, thereby affecting the sealing effect. For stains, it can be cleaned with alcohol or detergent. Install the threaded oil seal in the specified direction. The direction of the edge of the threaded oil seal cannot be wrong, otherwise, its sealing effect will be deteriorated. For example, threaded oil seals used in some transmissions and transmission shaft intermediate supports have this requirement, and attention must be paid during assembly.
It can be seen from the above description that when installing the automobile thread oil seal, pay attention to selecting the oil seal that meets the original design requirements; disassembling and assembling the oil seal, the method should be gentle; wipe it clean, and install it in the specified direction. At the same time, the tightness of the threaded oil seal after reassembly needs to be appropriate. If it is too tight, the oil seal will increase the rotational resistance of the sealed part; if it is too loose, the oil seal will not have the proper sealing effect. Reminder: The oil seal brand is selected with integrity and complete specifications. Welcome to sample and customize.
