Schley 80500 VW Oil Pressure Piston Puller.
This quality tool has been designed to remove the oil pressure relief piston in Volkswagen engines. A piston which many times gets stuck due to corrosion and gunk buildup and which should be removed during an engine overhaul for thorough oil passage cleaning, insuring proper piston operation. In use, this tool simply slides inside the case into the piston, then with the tools tip expanded, it grabs hold of the piston pulling it out along with the tool. This precision made tool is a necessity when overhauling a VW engine or just checking out oil pressure problems. For use on all type I, II, III, & IV engines.
