Remove one shaft end at a time!
Action
Remove the VK cover using one of the re-
commended methods:
• Drive a screwdriver (or similar)
through the VK cover, as close as
possible to the center of the VK
cover, and bend out the cover. If not
making a hole in the center of the
VK cover, there is a risk of damaging
the bearing inside. The damaged VK
cover must be replaced with a new.
• Remove the protection screw from
the vent hole and use air pressure
through the hole to blow out the
cover. The cover can be reused if
not damaged.
Wipe off all residual grease inside the re-
cess.
