雪佛兰K2500郊区前曲轴密封件更换在您的家庭或办公室。

我们的建议：

One of the most important parts of your car, crankshaft seals are typically made from a durable material, such as a synthetic rubber or silicone, designed to handle the extreme pressure and temperatures as well as the caustic chemicals in your engine oil. Because they are exposed to such abuse, main seals are subject to a lot of wear and tear. And whether you are talking a front or rear main seal, replacement is the only cure when one malfunctions.

好消息是密封件是相对便宜的组件。坏消息是，都不容易更换。

Front seal:The front seal is located behind the main pulley that drives all the belts, which is, of course, always spinning. The main pulley throws any leaking oil out in a big circle. It can get thrown up on the alternator, steering pump, belts, in short anything attached to the front of the engine and cause a real mess and eventually some serious damage. Consequently, it has to be removed along with many of the components attached to the front of the block to replace the front main seal.

后密封：后曲轴密封与变速箱一起放置；因此，更换它的过程需要去除传输以及离合器和飞轮组件。这是一项非常参与的工作。
