0.022–0.43 ft·lbf)
c. Out of specification → Tighten the nut further.
d. Repeat steps (a) to (c) until the starting
torque is within specification.
TIP
• Be careful not to exceed the specified starting
torque.
• If the specified starting torque is exceeded, re-

NOTICE
Check each bearing. The needle bearings
can easily fall out of their races. Slide the
yoke back and forth on the bearings; the
yoke will not go all the way onto a bearing if
a needle is out of place.
d. Press each bearing into the yoke using a suit-
able socket.
TIP
The bearing must be inserted far enough into the
yoke so that the circlip can be installed.

e. Install the circlips "2" into the groove of each
bearing.
