Crankshaft Socket Tool For Degree Wheel Don't use the crank hub retaining bolt to rotate your engine! By removing the crank hub or balancer and using a Moroso Crankshaft Socket Tool, engine builders have a positive way to turn over the engine. This tool makes it easier to locate TDC and BDC when degreeing camshafts. Broached keyway allows the socket (which fits 1/2" drive) to slide over the crankshaft snout and key. A knurled jam nut is then used to position a degree wheel.

Crankshaft Socket Tool Designed to simplify the task of crankshaft rotation during short block assembly with the balancer removed. Manufactured of tool quality steel with gold iridite finish. Accepts 1/2" drive.
