The kit includes adaptable arms plus both 6mm and 8mm mounting bolts so you can position the splitter on a variety of bolt patterns. Built for repeatable shop use, it reduces prying and improvised methods that risk scoring or warping case faces.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the TUSK splitter remove a crank assembly from vertically split cases?\u003c\/h3\u003e\n\u003cp\u003eThe tool uses a central forcing bolt and adjustable arms to apply even pressure that pushes the crank out while the case halves remain supported. Instead of levering or hammering, the splitter transfers controlled axial force to separate mating faces cleanly. This preserves bearing seats and alignment features for easier reassembly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCentral drive bolt applies steady, controllable axial force\u003c\/li\u003e\n  \u003cli\u003eAdjustable arms attach to existing case studs or tapped holes\u003c\/li\u003e\n  \u003cli\u003eEven pressure prevents tilting and reduces sealing surface damage\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat mounting options does it include and why do they matter?\u003c\/h3\u003e\n\u003cp\u003eBecause engine manufacturers use different stud sizes and patterns, the TUSK splitter ships with both 6mm and 8mm bolts to fit common configurations. The adjustable arms slide to match staggered or widely spaced studs, making the tool compatible with most vertically split 2‑ and 4‑stroke crankcases. Proper mounting keeps the forcing bolt aligned with the crankshaft centreline for safe separation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e6mm and 8mm mounting bolts included for broader compatibility\u003c\/li\u003e\n  \u003cli\u003eSliding arm channels suit varied stud spacing and angles\u003c\/li\u003e\n  \u003cli\u003eSecure bolting prevents slippage during extraction\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill this tool protect my engine parts during disassembly?\u003c\/h3\u003e\n\u003cp\u003eYes — the splitter is engineered to apply uniform force rather than concentrated leverage, which lowers the risk of cracked cases, damaged bearings or warped surfaces. By guiding the crank assembly straight out, it reduces lateral stresses on seals and shafts. Still, follow standard procedures: support the case halves and inspect mating surfaces before pressurized reassembly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eGuided axial extraction reduces bearing and journal damage\u003c\/li\u003e\n  \u003cli\u003eAvoids hammering or prying that can gouge case faces\u003c\/li\u003e\n  \u003cli\u003eWorks with supported case halves to maintain alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow simple is it to set up and use in a home or professional shop?\u003c\/h3\u003e\n\u003cp\u003eSetup is straightforward: mount the adjustable arms to existing case studs using the included bolts, align the forcing bolt with the crank, and turn the drive bolt to separate the halves. No specialized presses or fixtures are required, though a stable workbench and proper supports are recommended. Its repeatable operation makes it practical for one-off repairs or busy shop workflows.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick assembly with common wrenches and the supplied bolts\u003c\/li\u003e\n  \u003cli\u003eFits a range of engine makes with minimal adjustments\u003c\/li\u003e\n  \u003cli\u003ePortable enough for mobile mechanics and compact shops\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho this tool is for: The TUSK crankcase splitter is aimed at motorcycle and ATV technicians, DIY engine rebuilders, and small‑engine specialists who regularly service vertically split crankcases. If you remove crankshafts from 2‑stroke or 4‑stroke engines and want a safer, faster alternative to improvised separation methods, this kit offers the adjustability and hardware needed for reliable, damage‑minimizing disassembly.\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 this fit all vertically split crankcases?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: It fits most common vertically split 2‑ and 4‑stroke crankcases thanks to adjustable arms and included 6mm and 8mm bolts, but check stud spacing before purchase.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do I need extra tools to use the splitter?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Only basic hand tools to tighten mounting bolts and turn the forcing bolt; a stable bench and supports for the case halves are recommended.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"TUSK","offers":[{"title":"Default Title","offer_id":55170521432407,"sku":"B0039L9PSU","price":106.22,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/tusk-splitter-front-view.jpg?v=1790430147","url":"https:\/\/britishgarage.co.uk\/products\/tusk-crankcase-splitter-adjustable-arms-with-6mm-8mm-bolts-for-vertically-split-2-and-4-stroke-engines","provider":"British Garage","version":"1.0","type":"link"}
