STEP 7 Lubricating the bearings
Use any piece of fabric to protect
your working surface from grease.
Make sure the bearing is clean
inside.
Wipe the preservative oil off the
bearing surface with a paper towel.
It is necessary to lubricate all 4
rows of balls inside the bearing.
STEP 8 Lubricating the bearings
Turn with the tube and applicator clockwise until you feel a slight resistance. This
means that the holes in the applicator are aligned with the ball rows.
Gently press the tube to push the lubricant into the ball rows of the bearing.
Look at the front of the bearing. When the applicator pushes the lubricant out
(around the black gasket), stop pressing the tube. Hold the bearing with the other
hand during the lubricating.
The grease must be spread evenly over all four ball rows inside the bearing. There
must not be too much grease, or too little. Take a closer look at the last picture.
Wipe off excess grease on the outside of the bearing with a paper towel.
Use this procedure for both bearings.
