of bearings. Do not apply oil to the back surfaces, but thor-
oughly clean them.

bearing cap, all in the same direction. (when using a protrac-
tor)

+Always use either an angle wrench (SST) or protractor
during angular tightening. Avoid tightening based on
visual checks alone.

to observe the following as it may adversely affect elec-
tronic control systems depending on installation location.
