COMP Cams 4797 - Comp Cams Crankshaft Sockets
Comp Cams Crankshaft Sockets
When slipped on the end of a crankshaft, these specially designed 1/2" drive sockets allow you to rotate the engine assembly. These sockets also provide a great way to attach a degree wheel (Part number 249-4790 or 249-4791-1) to the engine. The unique design incorporates a knurled retaining nut that sandwiches the degree wheel and holds it in place. This nut can be loosened while on the crank snout so that the wheel can be turned independent of the engine when finding top dead center.
