are free of damage and do not show any signs of
wear.
Fig. 6
If a ball or roller bearing of a bearing pair shows de-
l
fects, both ball or roller bearings need to be re-
placed.
Remove any lubricant residues from the ball or roll-
l
er bearing to be examined by washing it with gaso-
line or any other appropriate degreasing agent.
Ensure strict cleanliness.
Check balls or rollers, running surfaces, outer faces
l
of outer races and inner faces of inner races for vis-
ible damage. Replace the ball or roller bearing if
necessary.
Check the ball or roller bearing for clearance and re-
l
sistance between the inner and outer races, replace
if necessary.
Lubricate the ball or roller bearing with the recom-
l
mended type of grease before assembly or reas-
sembly.
On greased bearings (e.g. wheel bearings) fill the
l
space between ball or roller bearing and outer seal
with the recommended type of grease before as-
sembling the seal.
