Einleitung
This guide shows how to remove and replace the two driveshaft bearings for the Toro Cement Mixer 68009HD.
In order to remove the gear-side bearing, you must remove the driveshaft. This requires removing the tub first. You may be able to extract the pulley-side bearing without removing the driveshaft and tub.
Warning: The tub is extremely heavy and requires at least two people to lift it. Be sure to practice safe lifting techniques.
