ABSTRACT:
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.
