The Tusk tool features adjustable arms that adapt to many bolt patterns and ships with both 6mm and 8mm mounting bolts, making it a practical choice for a wide range of motorcycle, ATV, and small engine projects.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool make crankcase separation safer?\u003c\/h3\u003e\n\u003cp\u003eThe Tusk splitter applies consistent, controlled force across the case joint so you avoid prying or hammering on delicate mating surfaces.

Having the correct bolt size, a clean work area, and a gentle backing support for the case halves will make the separation smooth and safe.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eRemove external covers, clutch, stator, or gear components as required\u003c\/li\u003e\n  \u003cli\u003eUse the supplied 6mm and 8mm bolts that match your case threads\u003c\/li\u003e\n  \u003cli\u003eSupport one case half on a flat, soft surface to avoid marring\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this tool for? The Tusk crankcase splitter is aimed at professional mechanics, home wrenchers, and restoration hobbyists who regularly work on vertically split engines and want to speed up bottom‑end jobs while minimizing damage risk. It’s especially useful if you perform frequent rebuilds, service older machines with seized halves, or prefer using purpose‑built tools to reduce repair time and costly mistakes. If you need a durable, adjustable splitter that covers many common bolt patterns and includes both 6mm and 8mm mounting hardware, this Tusk tool is a practical addition to your toolbox.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the Tusk splitter fit my engine bolt pattern?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: The adjustable arms fit many common vertically split crankcase bolt patterns; check measurements against your case and use the supplied 6mm or 8mm bolts as needed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can this tool remove the crank assembly without damaging it?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the central pushing screw applies controlled axial force to extract the crank without hammering, reducing risk to journals and seals.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"TUSK","offers":[{"title":"Default Title","offer_id":48081466359966,"sku":"B0039L9PSU","price":109.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/tusk-crankcase-splitter-front-view.jpg?v=1785805915","url":"https:\/\/northtrailauto.ca\/products\/tusk-crankcase-splitter-tool-for-vertically-split-2-stroke-4-stroke-engines-adjustable-arms-6mm-8mm-bolts","provider":"North Trail Auto","version":"1.0","type":"link"}
