ABSTRACT:
A keyless valve spring retainer for an internal combustion engine. The valve spring retainer has a high load strength yet can be easily assembled or unassembled on a valve stem. It includes a curved arm portion which permits the spring retainer to be located as close to the valve stem as possible yet long enough so as to be bendable for assembly or unassembly. The valve spring retainer in one embodiment clamps on the valve stem thus inhibiting rotation of the valve stem. In another embodiment, the valve spring retainer is not clamped thereon to allow rotation of the valve stem. It is adaptable to being used with a support plate for increased loading as well as externally or internally of a valve spring.
