摘要： Preferably, a motorcycle valve spring removal tool includes a motorcycle engine operatively mounted and secured to a frame of a motorcycle, and a valve spring compression tool secured to the motorcycle engine for use in removing a valve spring of the motorcycle engine while the cylinder head remains torqued to the cylinder, and the motorcycle engine remains mounted and secured within the motorcycle frame. In a preferred embodiment, the valve spring compression tool includes a base plate supporting a stud reception member that provides a threaded stud attachment aperture, in which a corresponding threaded stud is secured. Also included in the preferred embodiment is a compression plate interacting with the threaded stud and a force transfer component, preferably a threaded nut, also interacting with the stud to impart a compression force on the valve spring to achieve a predetermined level of compression of the valve spring.

摘要： A tool for the removal and replacement of valve springs on the cylinder head of an internal combustion engine while the cylinder head is either mounted to the engine block within the vehicle or is positioned on a work bench apart from the engine. The tool comprises a bracket component that is mounted by a number of bolts to the cylinder head to be worked on. The bracket includes a number of upright threaded bolts each associated with an adjacent upright guide. A pressure plate is progressively positioned on each set of the upright bolts and upright guides. Beneath the pressure plate are positioned two (or more) valve guides that engage the outer upper perimeter of two or more valve springs. A nut is threaded on to the upright bolt in a manner that forces the pressure plate and the valve guides downward onto the valve springs. Compression of the springs releases the split rings or collars that hold the valve springs to the valve stems. The end of the valve stems that incorporate the split ring attachment mechanisms are allowed to move upward into the valve guides while the perimeter of the spring is compressed. In this manner the split ring can be removed and the springs released upon removal of the nut from the threaded upright bolt. The pressure plate may then be moved to the next upright bolt on the bracket to effect removal of the adjacent set of valve springs.

摘要： A valve spring compressor hand tool quickly mounted on a rocker arm mounting stud on the top of a cylinder head for compressing a valve stem spring to release and remove the valve retainer lock for replacing a single valve spring, stem seal, or shield without removing the cylinder head on many automotive engine models. The valve spring compressor is a three piece tool including a mounting stud thread lock position engaging tool element with an internal half thread section, a threaded top and a tilt support base, a sleeve having a bifurcated valve spring top engaging side extension rotationally keyed to and slideable along the tool element from the top thereof to a keyway bottom stop position, and a manual handle member internally threaded to fit the threaded top of the thread lock position engaging tool element and turnable downward against the top of the sleeve with the bifurcated side extension to press the sleeve downward compressing the valve spring for valve retainer lock removal.

摘要： A generally cylindrical adapter which may be used with a conventional C-clamp valve spring compressor is made of a material such as nylon which will not scratch the cam follower bore of an overhead cam engine. The adapter has a groove in its upper portion for connecting to the jaw assembly of the C-clamp compressor, and has a flat annular lower end face for applying the compressing force from the C-clamp compressor to the valve spring assembly. As the compressing force is applied, the valve stem will be received in a central axial opening in the adapter, until the collets become accessible through lateral openings or access ports in the lower portion of the adapter. The collets may thus be removed through the lateral openings for disassembly of the valve spring assembly or may be returned to the valve stem through the lateral openings for reassembly. The adapter provides sufficient clearance so that the C-clamp compressor may be used to compress the valve spring of an overhead cam engine.
摘要翻译：可与常规C型夹紧阀弹簧压缩机一起使用的大致圆柱形适配器由诸如尼龙的材料制成，其不会划伤顶置凸轮发动机的凸轮从动孔。适配器在其上部具有用于连接到C形夹紧压缩机的钳口组件的凹槽，并且具有用于将来自C形夹紧压缩机的压缩力施加到阀弹簧组件的平坦的环形下端面。当施加压缩力时，阀杆将被容纳在适配器中的中心轴向开口中，直到夹头通过适配器下部中的横向开口或进入口容易接近。因此，夹头可以通过侧向开口移除以拆卸阀弹簧组件，或者可以通过横向开口返回到阀杆，用于重新组装。适配器提供足够的间隙，使得C形夹紧压缩机可用于压缩顶置凸轮发动机的气门弹簧。
