7.9 Checking for grease / oil leaks
Check the area around the bearing cover, brake drum, brake linings as well
as the lower and/or inner area of the traction sheave for traces of oil. For the
check, remove the cover plate above the traction sheave!
A small amount of escaping oil means individual drops of oil or traces of oil in
the inner area of the traction sheave / brake drum.
This can be a visual check or a manual check by reaching through the
spokes of the traction sheave.
