Camshaft base circle diagram

WebCamshaft base circle, block deck height, cylinder head design and lifter design all contribute to possible errors in geometry, which must be compensated for with pushrod length and shaft height. Usually, a longer than stock pushrod will be necessary in a high performance engine, but care must be taken to choose the correct length. Move to Top WebConsider the following statements regarding cams: 1. Base circle is the smallest circle tangent to the cam profile (contour) drawn from the centre of rotation of a radial cam. 2. Pitch curve is the curve drawn by the trace point assuming that the cam is fixed, and the trace point of the follower rotates around the cam. 3.
