The risks/issues of a bad rear bearing are not holding a tune, crank can get worn, and worst of all the bearing comes apart and eats your piston/sleeve.Installation: The best way to install is to use a bearing puller/installer, OFNA makes a very affordable one. If you place the new bearing in the freezer for 15 minutes it will be easier to install.Positioning: For proper lubrication, face the open side where you can see the balls to the rear of the motor (not the clutch side).Break In: For the first run of these bearings, We suggests that you fatten your motor up on the high-end needle so the ceramic balls will seat instead of skidding them.
