- Diagnosing: If you hold the head of the engine with your hand and the rattling sound disappears then you have a worn-out rear bearing. 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).
