5. Install the New Bearing

Place the new Komatsu 930E roller bearing in the seat. Make sure it sits flush. "A little grease won’t hurt," suggests Anna, a mechanical engineer. It helps with installation.

Attach all bolts and components back into place. Use a torque wrench to ensure everything is tightened to the manufacturer's specifications. This step is crucial for the longevity of your machine.
