Built with adjustable arms and supplied 6mm and 8mm mounting bolts, this tool adapts to common bolt patterns so you can apply even, controlled force directly to the crankshaft or case bosses. It’s a practical addition to a home garage or a professional toolbox when you need a reliable, repeatable method to split cases cleanly.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the TUSK splitter avoid damaging crankcase surfaces?\u003c\/h3\u003e\n\u003cp\u003eThe splitter centralizes force so the crank assembly is pushed straight out of the opposing half, preventing uneven leverage that can chip or gouge sealing surfaces.
