Neither does it verify that the camshaft hasīeen properly ground with the correct duration lobes, which can drastically affect performance. It could be as little as 2° off or as much as 6°, depending on the exact lobe shape and the procedure used during the degreeing operation. Therefore, when you attempt to locate the middle (or centerline) of the asymmetrical lobe there is an automaticĮrror factor. Lobe being much more aggressive and the closing side being gentler. The truth is that most modern lobes are asymmetrical, with the opening side of the It makes the basic assumption that the lobe you areĬhecking is symmetrical, with its opening side being the exact same shape and size as the closing side of the lobe. The main problem with the centerline method is it has you finding the theoretical centerline of the intake and/or exhaust lobe and line up on it. We believe it is far better to degree theĬamshaft with either method than not to degree the cam at all but of the two methods, the duration at. Is There More Than One Way to Degree a Cam, and Which is Better?Ĭurrently there are two popular methods for degreeing a cam: the centerline method, and the duration at. If you have the tools and expertise, weĪlways recommend that the camshaft's position in the engine be degreed in. The cam you can never be sure that the parts are in correct position. If these tolerances stack up against you, it could throw you out of alignment. (the camshaft, crankshaft, timing chain, and sprockets), all with their own standards and tolerances. In reality, you are dealing with a group of components If the circumstances were perfect, one would only need to line up the marks on the timing chain sprockets and the cam would be degreed. A few degrees of misalignment can affect the engine's Way you will know if the rise and fall of the pistons properly matches the opening and closing of the valves, so the engine will run properly. The term "Degreeing In Your Camshaft" means you are making sure the camshaft's position in the engine coincides with that of the crankshaft, so that their rotation is synchronized.
