Oil seals are used to seal the crankshaft and cylinder block. One of them (front) is installed near the pulley, and the other (rear) is hidden behind the gearbox and clutch. The crankshaft oil seal itself costs a penny, but for the work of replacing it you will have to pay a round sum or spend a lot of time and physical strength. Therefore, it is necessary to take a responsible approach to the choice of spare parts when the time comes for repair. The recommendations of our experts will help you bypass the pitfalls when buying crankshaft oil seals.
Features, technologies, subtleties of repair
Features of the work of oil seals. Several factors negatively affect the crankshaft oil seals.
- The crankshaft rotates constantly during engine operation. Friction occurs between the oil seals and the shaft; only wear-resistant material can withstand such loads.
- There is a large amount of engine oil inside the engine, which, when heated, liquefies and strives to seep out. In order to keep it in the block and sump, the gland must remain elastic.
- The gland has to deal with temperature changes every day. It should be equally elastic in the temperature range -40 … + 200 ° C. Currently, manufacturers use synthetic materials such as NBR (-40 … + 120 ° C), FKM (-20 … + 180 ° C) and PTFE (-130 … + 200 ° C) for the manufacture of parts. ).
Dimensions. The tightness of the connection in the engine can be ensured by oil seals of certain sizes. And if the outer and inner diameters must correspond to the original, then the width can range from +3 to -2 mm.
Manufacturing technology. A high-quality oil seal differs from a low-quality one not only in material and dimensions, but also in manufacturing technology. The most popular are punching and profile cutting with a cutter. It all depends on the quality of tool sharpening, which affects the parameters of the working edge. The smoother and sharper it is, the more durable the oil seal will serve.
Subtleties of repair. A lot of unfairly negative reviews go to the crankshaft oil seals from different manufacturers. And the cause of leaks can be incorrect installation or a large depletion on the shaft. Unsurprisingly, when criticism is directed at established leaders, car builders are defending these brands. First of all, pay attention to the presence of wear on the shaft, and then carry out the correct seating of the sealing element.
