Use a dedicated crankcase splitter tool. Before dropping the new crank assembly into place, freeze the main bearings and gently warm the crankcase bearing bores with a heat gun to allow the bearings to seat square without side-loading the races.\u003c\/p\u003e\n\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/2-stroke-performance-quads-atv\"\u003eYamaha ATV \u0026amp; Quad Performance Parts\u003c\/a\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-4-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eYamaha 4-Stroke Performance Parts\u003c\/a\u003e\u003c\/li\u003e\n\t\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003eOff-Road Engine Tools \u0026amp; Equipment\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
