Place the four point angular contact ball bearings in the bucket and soak them in a bubble-free overflow. Remove the four point angular contact ball bearings before cooling the grease. The amount of residual grease is small. After the grease is cooled, remove the four point angular contact ball bearings and the amount of residual grease is large. Determine the amount of grease remaining as needed.
9. Wipe the outer grease of the four point angular contact ball bearings with a soft cloth or toilet paper to assemble the FAGfour point angular contact ball bearings onto the pulley. The maintenance work is over.
