You must completely split the right and left case halves to pull the old balancer bearings and press these fresh units in.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why should I replace my balancer bearings during a routine crank rebuild?\u003c\/strong\u003e\u003cbr\u003e\nA: If you drop a fresh, tight crankshaft assembly into an engine with worn balancer bearings, the remaining harmonic imbalance will quickly cause accelerated wear on your new main bearings and can ruin the internal engine casing alignment over time.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When reassembling your bottom end, you must verify that the timing marks on your counter balancer drive gear are perfectly aligned with the corresponding marks on the crankshaft gear. Missing the timing alignment by even a single tooth will cause the balancer to swing out of phase with the piston stroke, which actually doubles engine vibration instead of canceling it out. Always use a quality assembly lube on the bearing tracks during drop-in and torque the balancer locking nut to factory specs using an accurate inch-pound wrench.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz250f-yz250fx-performance-parts-and-accessories\"\u003eYamaha YZ250F \/ YZ250FX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz450f-performance-upgrades-engine-mods-and-accessories-moto-house-mx\"\u003eYamaha YZ450F Performance Parts\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/mx-off-road-motorcycle-tools\"\u003ePremium Case Splitters \u0026amp; Bottom End Engine Tools\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
