Overview of the motor mount and drive
unit components.
The brass spacer bush H12 is pushed
onto the motor shaft. Then
fi
t the pinion
gear S974.
The grub screw hole in the pinion is positi-
oned so that it lines up with the
fl
at spot on
the motor shaft.
Then put some Loctite on the thread of
the grub screw M4x4 573 and screw it into
the pinion. Check before tightening that
you are really on the
fl
at spot. Therefore
leave the screw slightly loose and feel the
endpoints of the
fl
at spot while turning the
pinion back and forth on the shaft. When
this is achieved tighten the screw with 1.7
Nm torque.
